2014-03-13hppa: Add _STACK_GROWS_* cases to pthread_attr_[sg]etstack.Carlos O'Donell3-1/+21
This is one of a several NPTL patches to build glibc on hppa. The pthread_attr_[sg]etstack functions are defined by POSIX as taking a stackaddr that is the lowest addressable byte of the storage used for the stack. However, the internal iattr variable of the same name in NPTL is actually the final stack address as usable in the stack pointer for the machine. Therefore the NPTL implementation must add and subtract stacksize for _STACK_GROWS_DOWN architectures. HPPA is a _STACK_GROWS_UP architecture and doesn't need to add or subtract anything, the stack address *is* the lowest addressable byte of the storage. Tested on hppa-linux-gnu, with no regressions. Can't impact any other targets because of the conditionals. If nobody objects I'll check this in at the end of the week. I can't see there being any objections to this patch except that it introduces more code to maintain for an old architecture (perhaps we'll get another _S_G_U target in the future?).
2014-03-13stop supporting bash-1.xMike Frysinger5-34/+20
We've stopped supporting toolchain packages older than 2009, so punting bash-1.x is reasonable when bash-2 was released almost 20 years ago.
2014-03-13delete ksh checksMike Frysinger4-73/+7
Nothing in the tree uses ksh anymore, so punt these checks.
2014-03-13sotruss: drop ksh support and add basic POSIX shell supportMike Frysinger3-10/+15
This script works fine under bash as-is, so we don't need ksh anymore. Once we tweak the function style, the code even works (for the most part) under a POSIX shell. The localized strings will be prepended with a $, but it is otherwise functional.

The current description says Tuesday when it meant to say Thursday (since that comes before Friday).
2014-03-13tst-longjmp_chk2: add comments/sanity checkMike Frysinger2-1/+11
If the longjmp checking code is slightly broken, this code can loop forever which isn't too helpful. Add a sanity check to keep that from happening. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2014-03-13Save and restore AVX-512 zmm registers to x86-64 ld.soIgor Zamyatin12-40/+609
AVX-512 ISA adds 512-bit zmm registers. This patch updates _dl_runtime_profile to pass zmm registers to run-time audit. It also changes _dl_x86_64_save_sse and _dl_x86_64_restore_sse to upport zmm registers, which are called when only when RTLD_PREPARE_FOREIGN_CALL is used.

2014-03-12Fix __ASSUME_PSELECT for MicroBlaze (bug 16642).Joseph Myers3-2/+11
Reviewing (for all architectures, with a baseline kernel version of 2.6.32) the kernel support for features for which __ASSUME_* macros would be affected by a move to 2.6.32 as minimum kernel version showed up that __ASSUME_PSELECT was wrongly defined for MicroBlaze, despite the corresponding syscall table entry not being wired up in the MicroBlaze kernel. This patch makes the MicroBlaze kernel-features.h undefine __ASSUME_PSELECT. I'd also encourage wiring it up in the kernel (so you can then make this #undef conditional, and eventually obsolete once a recent-enough kernel is required). I suspect it wasn't wired up because of the mistaken comment in asm/unistd.h "obsolete -> sys_pselect7" (there is no such syscall as pselect7). [BZ #16642] * sysdeps/unix/sysv/linux/microblaze/kernel-features.h (__ASSUME_PSELECT): Undefine.
2014-03-12PowerPC: Fix bzero definition for static libc for PPC32Adhemerval Zanella4-3/+22
This patch fixes an issue for powerpc32-fpu static build which fails with an 'bzero' undefined reference. This patch adds bzero ifunc selector for static builds and fixes the '__bzero_ppc' reference to default memset symbol (since static memset build does not provide ifunc selector). Fixes BZ#16689.
2014-03-12Provide correct buffer length to netgroup queries in nscd (BZ #16695)Siddhesh Poyarekar3-2/+8
The buffer to query netgroup entries is allocated sufficient space for the netgroup entries and the key to be appended at the end, but it sends in an incorrect available length to the NSS netgroup query functions, resulting in overflow of the buffer in some special cases. The fix here is to factor in the key length when sending the available buffer and buffer length to the query functions.

This patch makes the strspn ifunc selector build for static builds.
2014-03-11Fix MIPS libc_feresetround*_ctx to preserve exceptions.Joseph Myers2-10/+10
Testing on mips64 showed missing underflow exceptions (from exp, for example) in non-default rounding modes, caused by libc_feresetround*_ctx wrongly restoring a saved environment without preserving exceptions, when that's only valid for the _noex variants. (I don't know why Steve didn't see this in his testing.) This patch fixes this by using libc_feupdateenv_mips_ctx for the relevant macros and removing the problem definitions. The problem definitions aren't suitable for the _noex macros either because they only discard exceptions in non-default rounding modes, and while for some uses of *_noex/*_NOEX it doesn't matter whether exceptions are discarded, dbl-64/e_remainder.c requires SET_RESTORE_ROUND_NOEX to cause exceptions to be discarded. I think the accumulated set of macros / functions for optimized exception / rounding mode handling could do with a careful review by now, and possible refactoring, and at least one new feature (extracting the saved rounding mode from an environment / context variable - see dbl-64/e_sqrt.c for a case where this could be used). Tested mips64. * sysdeps/mips/math_private.h [__mips_hard_float] (libc_feresetround_ctx): Define to libc_feupdateenv_mips_ctx not libc_feresetround_mips_ctx. [__mips_hard_float] (libc_feresetroundf_ctx): Likewise. [__mips_hard_float] (libc_feresetroundl_ctx): Likewise. [__mips_hard_float] (libc_feresetround_mips_ctx): Remove.
2014-03-11Fix nextafter overflow in non-default rounding modes (bug 16677).Joseph Myers9-20/+42
ISO C requires the result of nextafter to be independent of the rounding mode, even when underflow or overflow occurs. This patch fixes the bug in various nextafter implementations that, having done an overflowing computation to force an overflow exception (correct), they then return the result of that computation rather than an infinity computed some other way (incorrect, when the overflowing result of arithmetic with that sign and rounding mode is finite but the correct result is infinite) - generally by falling through to existing code to return a value that in fact is correct for this case (but was computed by an integer increment and so without generating the exceptions required). Having fixed the bug, the previously deferred conversion of nextafter testing in libm-test.inc to ALL_RM_TEST is also included. Tested x86_64 and x86; also spot-checked results of nextafter tests for powerpc32 and mips64 to test the ldbl-128ibm and ldbl-128 changes. (The m68k change is untested.)

2014-03-11PowerPC: Fix bzero definition for static libc for PPC64Adhemerval Zanella3-6/+14
This patch fixes an issue for powerpc64[le] static build where __bzero is definied in multiple places (memset-ppc64.o and bzero.o). It is now defined only in bzero.o and memset-ppc64.o only defined __bzero_ppc for both dynamic and static library. Fixes BZ#16683.
2014-03-11PowerPC: strspn optimization for PPC64/POWER7Vidya Ranganathan8-4/+296
The optimization is achieved by following techniques: > hashing of needle. > hashing avoids scanning of duplicate entries in needle across the string. > initializing the hash table with Vector instructions (VSX) by quadword access. > unrolling when scanning for character in string across hash table.
2014-03-10PowerPC: strncat optimization for PPC64Adhemerval Zanella7-1/+346
The optimization is achieved by following techniques: 1. Doubleword aligned memory access and compares using cmpb instruction. 2. Loop unrolling for byte load/store. 3. CPU pre-fetch to avoid cache miss.
2014-03-10Mark nscd service as forking in systemd service file (BZ #16639)Siddhesh Poyarekar3-3/+8
Currently the nscd service is installed in systemd as a simple service, which means that it is able to handle its own errors and does not quit. Since nscd does not fit that description, i.e. it can exit on errors like, say, failing to parse nscd.conf, it should be declared as forking instead.
2014-03-08PowerPC: Fix modf/modff optimization return signAdhemerval Zanella3-4/+10
This patch fix the optimized powerpc-fpu modf/modff implementation when using in non-default rounding mode where the zero sign is not as expected. It fixes the libm testsuite tests modf_downward (0) == 0.00000000000000000000e+00 modf_downward (20) == 0.00000000000000000000e+00 modf_downward (21) == 0.00000000000000000000e+00 Where the sign returned was negative.
2014-03-08Add libm-test.inc macro for all-rounding-modes testing.Joseph Myers2-325/+130
This patch adds support in libm-test.inc for automatically running tests of a function in all rounding modes, in the form of a macro ALL_RM_TEST to loop over all rounding modes when running tests of a function, and uses it for functions whose results should always be independent of the rounding mode. Conversion of tests of nextafter to ALL_RM_TEST was deferred because trying that conversion showed up bug 16677. (Finding such a bug of course illustrates the point of testing more systematically in all rounding modes rather than only reactively when bugs get reported in a particular function in a non-default mode.) Conversion of tests where results can depend on the rounding mode will follow once I add gen-libm-test.pl support for using different initializers for the expected results for different rounding modes (again, some conversions may need deferring until bugs are fixed, depending on how straightforward they are to XFAIL in a particular context). Some existing tests get run five times rather than four, with round-to-nearest tests both run in that as default rounding mode and also with it explicitly set with fesetround (FE_TONEAREST). This duplication doesn't seem particularly useful, so ALL_RM_TEST only runs tests four times. Tested x86_64 and x86. * math/libm-test.inc (ALL_RM_TEST): New macro. (ceil_test): Use ALL_RM_TEST.

2014-03-07Include all of <time.h> from <sched.h> for older standards (bug 16670).Joseph Myers4-5/+14
This patch fixes one of the header namespace issues shown up by conformtest, <sched.h> failing to expose all symbols from <time.h> as required by older standards. The patch keeps the existing behavior if __USE_XOPEN2K is defined (the default; POSIX.1-2001 was the version that made it optional to expose these symbols), but ensures that all the symbols from <time.h> are exposed if an older standard is selected. Tested x86_64. [BZ #16670] * posix/sched.h [!__USE_XOPEN2K] (__need_time_t): Don't define before #include of <time.h>.

2014-03-07[PATCH] [AArch64] Optional trapping exceptions support.Marcus Shawcroft3-0/+29
Trapping exceptions in AArch64 are optional. The relevant exception control bits in FPCR are are defined as RES0 hence the absence of support can be detected by reading back the FPCR and comparing with the desired value.
2014-03-07Count miscellaneous files built on host for testing as tests.Joseph Myers5-17/+45
In <https://sourceware.org/ml/libc-alpha/2014-01/msg00198.html> I raised the question of counting miscellaneous dependencies of tests, built on the host rather than the build system, as tests, so that when test failures don't stop "make check" neither do those other builds on the host, so that a flaky host doesn't stop "make check" from producing a complete summary of test results. Brooks supported that idea in <https://sourceware.org/ml/libc-alpha/2014-02/msg00301.html>. This patch implements that change for all the examples I could find: one message catalog in catgets/, locales in localedata/ and timezone files in timezone/. Tested x86_64. * catgets/Makefile (tests-special): Add $(objpfx)sample.SJIS.cat. ($(objpfx)sample.SJIS.cat): Use $(evaluate-test). * timezone/Makefile (testdata): Move definition above include of Rules. (test-zones): New variable. (tests-special): Add zone files.

2014-03-07Make tests consistently use *.out output files.Joseph Myers11-62/+111
This patch systematically renames miscellaneous tests so their outputs use a *.out name (unless the test is just running some glibc program with its conventional output file name, rather than a special program at all, as in catgets tests generating *.cat). In the case of the iconv test test-iconvconfig, output is redirected where it wasn't before. In various places the "generated" variable is updated to reflect the revised test names; in iconvdata/Makefile a typo (mmtrace-tst-loading) is also fixed. resolv/Makefile sets both "generate" (which appears unused) and "generated". Bitrot in the settings of these variables could no doubt be fixed so that "make clean" after build and testing leaves results the same as after configure (and indeed the tests-special / xtests-special variables could be used to simplify things, by removing those files automatically rather than listing them manually in these variables), and "make distclean" leaves an empty build directory, but right now it appears various files don't get deleted. I think they are liable to continue to bitrot in the absence of routine testing that these targets actually work, given that building in the source directory isn't supported and that was the main use of such makefile targets. Tested x86_64. * elf/Makefile (tests-special): Rename tests to end with .out. ($(objpfx)noload-mem): Likewise. ($(objpfx)tst-leaks1-mem): Likewise.

2014-03-07Generate overall summary of test results.Joseph Myers4-0/+92
This patch, an updated version of <https://sourceware.org/ml/libc-alpha/2014-01/msg00197.html>, makes testsuite runs generate an overall summary of test results. A new script merge-test-results.sh deals both with collecting results within a directory to a file with all the results from that directory, and collecting the results from subdirectories into a single overall file (there's not much in common between the two modes of operation of the script, but it seemed silly to have two separate scripts for this). Within a directory, missing results produce UNRESOLVED lines; at top level, missing results for a whole directory produce an ERROR line (since toplevel can't identify what the specific missing tests are in this case). Note that this does not change the rules for when "make" considers there has been an error, or terminates, so unexpected failures will still cause make to terminate, or, with -k, mean the commands for "tests" don't get run because of failure of a dependency. Tested x86_64, including that the summary does in fact reflect all the tests with .test-result files. * scripts/merge-test-results.sh: New file. * Makefile (tests-special-notdir): New variable. (tests): Run merge-test-results.sh. (xtests): Likewise. * Rules (tests-special-notdir): New variable. (xtests-special-notdir): Likewise. (tests): Run merge-test-results.sh (xtests): Likewise.
2014-03-07conformtest: split up running of tests from makefile.Joseph Myers5-41/+474
This patch changes the logic by which header conformance tests are run so that the makefiles run the tests for each (standard, header) pair separately rather than as a single test (there are 518 such pairs being tested at present). Since these tests are slow and previously couldn't be run in parallel, this obviously speeds up the whole test run significantly when using parallel testing. There are other benefits. These tests can now be marked as expected to fail at the level of (standard, header) pairs, meaning that regressions introduced by a header change are much more likely to be spotted (of course, such a regression could be a bug in the header or in the expectations, most of which have not been properly checked against the relevant standards). The patch introduces lists in conform/Makefile of the headers to test for each standard, with a new (quick) test for each standard that the list agrees with the set of headers for which there are in fact nonempty expectations for that standard. This means that each of the 518 pairs being tested is actually something meaningful to test rather than a null test. I also hope to use these lists of headers in various standards in future tests for namespace violations where a function in a standard is implemented to call a non-reserved name for a function outside that standard. Although there are a lot of tests now marked as expected to fail, I expect most of those to be easy to fix (whether with fixes to the expectations, the headers or both - if fixing a header bug, of course file it in Bugzilla first); only a limited number are likely to reflect actual missing features in glibc. Tested x86_64 (GCC 4.7 branch). It's quite possible some failures vary from platform to platform, in which case either additional XFAILs can be added here, or platform-specific header bugs (if applicable) the failures show up can be fixed. I made XFAILs unconditional for tests that should only fail for GCC 4.6 and earlier; we could make the GCC version available in the makefiles and condition these, but simply moving the XFAILing to a finer granularity seems a clear improvement on the previous state of the whole of conformtest being XFAILed. * Makeconfig (test-xfail-name): New variable.

2014-03-07conformtest: clean up POSIX expectations for semaphore.h, signal.h, tar.h.Joseph Myers5-38/+172
Continuing the series of patches to clean up conformtest expectations for "POSIX" (1995/6) based on review of the expectations against the standard, this patch cleans up those for semaphore.h, signal.h and tar.h (including various corrections for other standards for the expectations affected by this patch). Tested x86_64. (Some of the failures for signal.h shown up by this patch correcting expectations for that header are among the reasons for posix/annexc being expected to fail. The goal is for conformtest eventually to replace posix/annexc and stdlib/isomac once it has all relevant functionality, and for the loop over standards and headers in conformtest to convert to separate makefile targets for each combination, so they can be run in parallel and so that xfails can be more specific than the present xfailing of the whole of conformtest.) * conform/conformtest.pl: Allow ' and \ in values given for constants. * conform/data/semaphore.h-data [POSIX] (fcntl.h): Allow header inclusion.

2014-03-06Enumerate tests with special rules in tests-special variable.Joseph Myers25-130/+207
This patch is a revised and updated version of <https://sourceware.org/ml/libc-alpha/2014-01/msg00196.html>. In order to generate overall summaries of the results of all tests in the glibc testsuite, we need to identify and concatenate the files with the results of individual tests. Tomas Dohnalek's patch used $(common-objpfx)*/*.test-result for this. However, the normal glibc approach is explicit enumeration of the expected set of files with a given property, rather than all files matching some pattern like that. Furthermore, we would like to be able to mark tests as UNRESOLVED if the file with their results is for some reason missing, and in future we would like to be able to mark tests as UNSUPPORTED if they are disabled for a particular configuration (rather than simply having them missing from the list of tests as at present). Such handling of tests that were not run or did not record results requires an explicit enumeration of tests. For the tests following the default makefile rules, $(tests) (and $(xtests)) provides such an enumeration. Others, however, are added directly as dependencies of the "tests" and "xtests" makefile targets. This patch changes the makefiles to put them in variables tests-special and xtests-special, with appropriate dependencies on the tests listed there then being added centrally. Those variables are used in Rules and so need to be set before Rules is included in a subdirectory makefile, which is often earlier in the makefile than the dependencies were present before. We previously discussed the question of where to include Rules; see the question at <https://sourceware.org/ml/libc-alpha/2012-11/msg00798.html>, and a discussion in <https://sourceware.org/ml/libc-alpha/2013-01/msg00337.html> of why Rules is included early rather than late in subdirectory makefiles. It was necessary to avoid an indirection through the check-abi target and get the check-abi-* targets for individual libraries into the tests-special variable. The intl/ test $(objpfx)tst-gettext.out, previously built only because of dependencies from other tests, was also added to tests-special for the same reason. The entries in tests-special are the full makefile targets, complete with $(objpfx) and .out. If a future change causes tests to be named consistently with a .out suffix, this can be changed to include just the path relative to $(objpfx), without .out. Tested x86_64, including that the same set of files is generated in the build directory by a build and testsuite run both before and after the patch (except for changes to the elf/tst-null-argv.debug.out.<number> file name), and a build with run-built-tests=no to verify there aren't any more obvious instances of the issue Marcus Shawcroft reported with a previous version in <https://sourceware.org/ml/libc-alpha/2014-01/msg00462.html>. * Makefile (tests): Change dependencies to ....

2014-03-06Prepare libm-test.inc structures for multi-rounding-mode testing.Joseph Myers3-88/+221
At present, libm-test.inc tests are run in multiple rounding modes by having a separate array for each rounding mode (which might or might not have the same test inputs as the other such arrays), a separate function calling a RUN_TEST_LOOP_* macro over that array, and a separate call to that function in main. The number of functions tested in multiple rounding modes has gradually increased as rounding-mode-specific bugs have been found and fixed in different functions. It would be better to be able to use a single macro call, in a single function, to run tests for a function over all rounding modes, with this being done for all libm functions except in cases where it's deferred until some bugs can be fixed because XFAILing all affected tests would be painful (that's why the full set of pow tests isn't currently run in all rounding modes). This patch helps prepare for that by making the structures storing expected results for tests store results for all four rounding modes. After this patch, the results for all modes are just duplicates, but tests access the appropriate field in the structure, so helping to pave the way for when the fields stop being duplicates and multiple rounding modes can be tested from a single array. Tests might in future specify a single set of results, to be used in all rounding modes; separate results for each rounding mode, specified manually; or use of auto-libm-tests-* to generate results for each rounding mode.

The __ASSUME_UTIMES macro describes whether the utimes syscall is present. For linux-generic architectures, it isn't (utimensat is instead), so the macro should not be defined for them; this patch removes the spurious definitions for such architectures. (Those definitions don't actually cause any user-visible bug, because futimes.c doesn't use __ASSUME_UTIMES if __ASSUME_UTIMENSAT is defined, and futimesat.c and utimes.c are overridden for linux-generic, but the definitions are still logically incorrect.) * sysdeps/unix/sysv/linux/aarch64/kernel-features.h (__ASSUME_UTIMES): Remove. * sysdeps/unix/sysv/linux/tile/kernel-features.h (__ASSUME_UTIMES): Likewise.
2014-03-06Adjust how gen-auto-libm-tests handles before-rounding/after-rounding cases.Joseph Myers4-327/+315
This patch changes gen-auto-libm-tests so that, when generating test results that depend on whether the architecture has before-rounding or after-rounding tininess detection, the :before-rounding or :after-rounding conditions go on the exception / errno flags generated, rather than generating two separate lines in auto-libm-test-out for e.g. flt-32:before-rounding and flt-32:after-rounding. The rationale for this is as follows. It would be desirable for testing a libm function in all rounding modes to require just one function and array in libm-test.inc, not four (or five), with the array of test data including expected results for all rounding modes rather than separate arrays for each rounding mode that also need to repeat all the test inputs. For gen-libm-test.pl to generate data for such an array from auto-libm-test-out, it would be helpful if each (format, test input) pair has exactly four lines in auto-libm-test-out, one for each rounding mode, rather than some rounding modes having just one line and some having two because the exceptions depend on tininess detection. Tested x86_64 and x86. * math/gen-auto-libm-tests.c: Update comment on output format. (output_for_one_input_case): Generate before-rounding and after-rounding information as conditions on output flags not floating-point format. * math/auto-libm-test-out: Regenerated. * math/gen-libm-test.pl (cond_value): New function.

2014-03-05Automatically check sanity of ulps from libm tests.Joseph Myers2-191/+407
This patch makes libm-test.inc apply sanity checks to ulps values resulting from tests, or found in libm-test-ulps files, to avoid the need for manual checking/editing of new ulps for cases that are excessively large or involve functions that should not have any ulps. For IBM long double, errors must be at most 14ulp (the largest currently checked-in value), or at most 3ulp (the documented error bound for division) in the case of exactly-determined functions; for other formats, the limits are 9ulp (also the largest currently checked-in value) and 0ulp. Limits from ulps files are saturated to those bounds, and regen-ulps will ignore any errors outside those bounds. (Thus if, say, you have an architecture-specific problem with fma, the tests can still be XFAILed in auto-libm-test-in, but errors outside the permitted range can no longer be listed in libm-test-ulps.) Tested x86_64. * math/libm-test.inc (max_valid_error): New variable. (init_max_error): Take new argument specifying whether function results are exactly determined. Set max_valid_error and bound other variables for errors based on this argument. (set_max_error): Do not record results above max_valid_error.

2014-03-05Don't include individual test ulps in libm-test-ulps.Joseph Myers24-218882/+95
As recently discussed <https://sourceware.org/ml/libc-alpha/2014-02/msg00670.html>, it doesn't seem particularly useful for libm-test-ulps files to contain huge amounts of data on ulps for individual tests; just the global maximum observed ulps for each function, together with the verification of exceptions, errno and special results such as infinities and NaNs for each test, suffices to verify that a function's behavior on the given test inputs is within the expected accuracy. Removing this data reduces source tree churn caused by updates to these files when libm tests are added, and reduces the frequency with which testsuite additions actually need libm-test-ulps changes at all. Accordingly, this patch removes that data, so that individual tests get checked against the global bounds for the given function and only generate an error if those are exceeded. Tested x86_64 (including verifying that if an ulps value is artificially reduced, the tests do indeed fail as they should and "make regen-ulps" generates the expected changes). * math/libm-test.inc (struct ulp_data): Don't refer to ulps for individual tests in comment.

2014-03-04Fix libm-test.inc:print_complex_max_error handling of some error cases.Joseph Myers2-8/+22
When regenerating ulps incrementally with "make regen-ulps", the resulting diffs should only increase existing ulps, never decrease them. This allows successive uses of "make regen-ulps" on different hardware or with different compiler configurations to accumulate ulps that are sufficient for tests to pass in a variety of configurations. However, sometimes changes that decrease ulps are wrongly generated; thus, when applying <https://sourceware.org/ml/libc-alpha/2014-02/msg00605.html> I had to remove such changes manually. The problem is print_complex_max_error. If the ulps for either the real or the imaginary part of a function are out of range, this function prints the maximum ulps seen for both parts, which then replace those previously in libm-test-ulps. So if the ulps for one part are bigger than recorded before, but those for the other part are smaller, the diffs reduce existing ulps. This patch fixes the logic so that only increased ulps get printed. Tested x86_64 ("make math/tests", and "make regen-ulps" in a situation with ulps manually modified so one part would go up and the other down, to confirm the changes have the intended effect then). * math/libm-test.inc (print_complex_max_error): Check separately whether real and imaginary errors are within allowed range and pass 0 to print_complex_function_ulps instead of value within allowed range.

2014-03-04Use cached offset in ftell when reliableSiddhesh Poyarekar5-23/+65
The cached offset is reliable to use in ftell when the stream handle is active. We can consider a stream as being active when there is unflushed data. However, even in this case, we can use the cached offset only when the stream is not being written to in a+ mode, because this case may have unflushed data and a stale offset; the previous read could have sent it off somewhere other than the end of the file. There were a couple of adjustments necessary to get this to work. Firstly, fdopen now ceases to use _IO_attach_fd because it sets the offset cache to the current file position. This is not correct because there could be changes to the file descriptor before the stream handle is activated, which would not get reflected. A similar offset caching action is done in _IO_fwide, claiming that wide streams have 'problems' with the file offsets. There don't seem to be any obvious problems with not having the offset cache available, other than that it will have to be queried in a subsequent read/write/seek. I have removed this as well. The testsuite passes successfully with these changes on x86_64.
