2013-11-06gdb/dwarf2read.c: Sanity check DW_AT_sibling values.Will Newton2-2/+26
When reading objects with corrupt debug information it is possible that the sibling chain can form a loop, which leads to an infinite loop and memory exhaustion.

2013-11-06Test on solib load and unloadYao Qi5-0/+260
This patch is to add a test case to on the performance of GDB handling load and unload of shared library. In V4: - Handle malloc and dlopen failure, - Document test parameters. In V3, there are some changes, - Adapt to perf test framework changes. - Measure load and unload separately. In V2, there are some changes, - A new proc gdb_produce_source to produce source files. I tried to move all source file generation code out of solib.exp, but compilation step still needs to know the generated file names. I have to hard-code the file names in compilation step, which is not good to me, so I give up on this moving. - SOLIB_NUMBER -> SOLIB_COUNT - New variable SOLIB_DLCLOSE_REVERSED_ORDER to control the order of iterating a list of shared libs to dlclose them. - New variable GDB_PERFORMANCE to enable these perf test cases. - Remove dlsym call in solib.c. - Update solib.py for the updated framework. gdb/testsuite/ * lib/gdb.exp (gdb_produce_source): New procedure. * gdb.perf/solib.c: New. * gdb.perf/solib.exp: New. * gdb.perf/solib.py: New.

2013-11-06Perf test frameworkYao Qi7-0/+491
This patch adds a basic framework to do performance testing for GDB. perftest.py is about the test case, testresult.py is about test results, and how are they saved. reporter.py is about how results are reported (in what format). measure.py is about measuring the execution of tests by a collection of measurements. In V5: - Simplify perftest.exp. In V4: - Rename MeasurementCPUTime to MeasurementCpuTime, - Add 'pass' in empty method, - Simplify string comparison in perftest.exp. - Rename GDB_PERFORMANCE to GDB_PERFTEST_MODE and rename GDB_PERFORMANCE_TIMEOUT to GDB_PERFTEST_TIMEOUT. In V3, there are some changes, - Add wall time measurement, cpu time measurement and vmsize measurement. - Rename SingleStatisticTestCase to TestCaseWithBasicMeasurements, which measures cpu time, wall time, and memory (vmsize). - GDB_PERFORMANCE=run|compile|both to control the mode of perf testing. - New GDB_PERFORMANCE_TIMEOUT to specify the timeout. - Split proc prepare to proc compile and startup. - Disable GC while doing measurements. In V2, there are several changes to address Doug and Sanimir's comments. - Add copyright header and docstring in perftest/__init__.py - Remove config.py. - Fix docstring format. - Rename classes "SingleVariable" to "SingleStatistic". - Don't extend gdb.Function in class TestCase. Add a new method run to run the test case so that we can pass parameters to test. - Allow to customize whether to warm up and to append test log. - Move time measurement into test harness. Add a new class Measurement for a specific measurement and a new class Measure to measure them for a given test case. - A new class ResultFactory to create instances of TestResult. - New file lib/perftest.exp, which is to do some preparations and cleanups to simplify each *.exp file. - Skip compilation step if GDB_PERFORMANCE_SKIP_COMPILE is set. gdb/testsuite/ 2013-11-06 Yao Qi <yao@codesourcery.com> * lib/perftest.exp: New. * gdb.perf/lib/perftest/__init__.py: New. * gdb.perf/lib/perftest/measure.py: New. * gdb.perf/lib/perftest/perftest.py: New. * gdb.perf/lib/perftest/reporter.py: New. * gdb.perf/lib/perftest/testresult.py: New.
2013-11-06New make target 'check-perf' and new dir gdb.perfYao Qi7-2/+41
We add a new dir gdb.perf in testsuite for all performance tests. However, current 'make check' logic will either run dejagnu in directory testsuite or iterate all gdb.* directories which has *.exp files. Both of them will run tests in gdb.perf. We want to achieve: 1) typical 'make check' should not run performance tests. In each perf test case, GDB_PERFTEST_MODE is checked. If it doesn't exist, return. 2) run perf tests easily. We add a new makefile target 'check-perf'. gdb: 2013-11-06 Yao Qi <yao@codesourcery.com> * Makefile.in (check-perf): New target. gdb/testsuite: 2013-11-06 Yao Qi <yao@codesourcery.com> * Makefile.in (check-perf): New target. * configure.ac (AC_OUTPUT): Output Makefile in gdb.perf. * configure: Re-generated. * gdb.perf/Makefile.in: New.

2013-11-04switch to fully parallel modeTom Tromey2-58/+56
This switches "make check" to fully parallel mode. One primary issue facing full parallelization is the overhead of "runtest". On my machine, if I "touch gdb.base/empty.exp", making a new file, and then "time runtest.exp", it takes 0.08 seconds. Multiply this by the 1008 (in my configuration) tests and you get ~80 seconds. This is the overhead that would theoretically be present if all tests were run in parallel. However, the problem isn't nearly as bad as this, for two reasons. First, you must divide by the number of jobs, assuming perfect parallelization -- reasonably true for small -j numbers, based on the results I see. Second, the current test suite parallelization approach bundles the tests, largely by directory, but also splitting up gdb.base into two halves. I was curious to see how the current bundling played out in practice, so I ran "make -j1 check RUNTEST='/bin/time runtest'". This invokes the parallel mode (thus the bundling) and then shows the time taken by each invocation of runtest. Then, I ran "/bin/time make -j3 check". (See below about -j2.) The time for the entire -j3 test run was the same as the time for "gdb.base1". What this means is that gdb.base1 is currently the time-limiting run, preventing further parallelization gains. So, I reason, whatever overhead we see from full parallelization will only be seen by "-j1" and "-j2". I then tried a -j2 test run. This does take longer than a -j3 build, meaning that the gdb.base1 job finishes and then proceeds to other runtest invocations. Finally I tried a -j2 test run with the appended patch. This was 9% slower than the -j2 run without the patch. I think that is a reasonable slowdown for what is probably a rare case. I believe this patch will yield faster test results for all -j values greater than 2. For -j3 on my machine, the test suite is a few seconds faster; I didn't try any larger -j values. For -j1, I went ahead and changed the Makefile so that, if no -j option is given, then the "check-single" mode is used. You can still use "make -j1 check" to get single-job parallel-mode, though of course there's no good reason to do so. This change is likely to speed up the plain "make check" scenario a little as we will now bypass dg-extract-results.sh. One drawback of this change is that "make -jN check" is now much more verbose. I generally only look at the .sum and .log files, but perhaps this will bother some. Another interesting question is scalability of the result. The slowest test, which limits the scalability, took 80.78 seconds. The mean of the remaining tests is 1.08 seconds. (Note that this is just a rough estimate, since there are still outliers.) This means we can run 80.78 / 1.08 =~ 74 tests in the time available. And, in this data set (slightly older than the above, but materially the same) there were 948 tests. So, I think the current test suite should scale ok up to about -j12. We could improve this number if need be by breaking up the biggest tests. 2013-11-04 Tom Tromey <tromey@redhat.com> * Makefile.in (TEST_DIRS): Remove. (TEST_TARGETS, check-parallel): Rewrite.

This fixes the gdb.xml tests to be parallel-safe. 2013-11-04 Tom Tromey <tromey@redhat.com> * gdb.xml/tdesc-arch.exp: Use standard_output_file. Make downloads conditional on remote host. (set_arch): Likewise. * gdb.xml/tdesc-regs.exp: Use gdb_remote_download. (load_description): Use standard_output_file.
2013-11-04fix up gdb.gdbTom Tromey3-4/+22
This fixes the gdb.gdb tests to be parallel-safe, by ensuring that the new "xgdb" file ends up in the standard output directory during the tests. 2013-11-04 Tom Tromey <tromey@redhat.com> * gdb.gdb/selftest.exp: Use standard_output_file. * lib/selftest-support.exp (do_self_tests): Use standard_output_file.
2013-11-04fix weird.exp for parallel testingTom Tromey2-1/+7
This fixes up gdb.stabs/weird.exp for parallel testing. This just means using gdb_remote_download and standard_output_file, so that the tests end up in the right place. 2013-11-04 Tom Tromey <tromey@redhat.com> * gdb.stabs/weird.exp: Use gdb_remote_download and standard_output_file.
2013-11-04fix some simple thinkos in the test suiteTom Tromey3-3/+11
This fixes some parallelization thinkos from a while ago. I'm not sure how the problems ever slipped through. In addition to a thinko fix in twice.exp, this also finishes fixing it up for parallelization. 2013-11-04 Tom Tromey <tromey@redhat.com> * gdb.base/gcore-buffer-overflow.exp: Use standard_output_file, not standard_testfile. * gdb.base/twice.exp: Use standard_testfile, not standard_output_file. Use gdb_remote_download.
2013-11-04fix up log-file togglingTom Tromey2-1/+7
Currently a proc in gdb.exp toggles the expect (and thus dejagnu) logging. This is not a super idea, but it is there to avoid putting some preprocessor output into the log. In the right circumstances, this can result in the log file being mysteriously truncated. I think this happens because it doesn't necessarily write to the correct log file again. The fix is to use "log_file -info" to save the previous log file. 2013-11-04 Tom Tromey <tromey@redhat.com> * lib/gdb.exp (get_compiler_info): Use log_file -info and restore from that.
2013-11-04x86-64/gas: fix an asymmetry in suffix/register checkingJan Beulich6-5/+49
Without this, constructs like "orw %rax, (%rax)" aren't being rejected (other than any other wrong suffix/register combination). gas/ 2013-11-04 Jan Beulich <jbeulich@suse.com> * config/tc-i386.c (check_long_reg): Correct comment indentation. (check_qword_reg): Correct comment and its indentation. (check_word_reg): Extend comment and correct its indentation. Also check for 64-bit register. gas/testsuite/ 2013-11-04 Jan Beulich <jbeulich@suse.com> * gas/i386/x86-64-suffix-bad.[sl]: New. * gas/i386/i386.exp: Run new test.
2013-11-04Improve performance of large restore commandsAnton Blanchard2-0/+11
I noticed a large (100MB) restore took hours to complete. The problem is memory_xfer_partial repeatedly mallocs and memcpys the entire 100MB buffer for breakpoint shadow handling only to find a small portion of it is actually written. The testcase that originally took hours now takes 50 seconds. gdb/ 2013-07-29 Anton Blanchard <anton@samba.org> * target.c (memory_xfer_partial): Cap write to 4KB.
2013-11-04Remove powerpc.cc copy of use_plt_offsetAlan Modra2-115/+37
This adds an extra flag for needs_dynamic_reloc() in order to remove the copy of this function and use_plt_offset() in powerpc.cc, and tweaks the powerpc get_reference_flags() to return the flag as appropriate. ELFv2 does not want ELFv1 behaviour here. * symtab.h (Symbol::Reference_flags): Add FUNC_DESC_ABI. (Symbol::needs_dynamic_reloc): Test new flag. * powerpc.cc (needs_dynamic_reloc, use_plt_offset): Delete. (Target_powerpc::Scan::get_reference_flags): Add target param. Return FUNC_DESC_ABI for 64-bit ELFv1. (Target_powerpc::Branch_info::make_stub): Adjust get_reference_flags call. (Target_powerpc::Scan::global): Use Symbol::needs_dynamic_reloc. (Target_powerpc::Relocate::relocate): Use Symbol::use_plt_offset.

2013-11-04Edit ELFv2 global entry prologue to non-PICAlan Modra4-2/+44
Changing addis r2,r12,..; addi r2,r2,.. to lis r2,..; addi r2,r2.. in non-PIC executables has the benefit of removing a dependency on r12. bfd/ * elf64-ppc.c (ppc64_elf_relocate_section): Edit global entry prologue to non-PIC in non-PIC executables. ld/testsuite/ * ld-powerpc/elfv2exe.d: Adjust for non-PIC global entry.
2013-11-04PowerPC64 ELFv2 symbols defined in pltAlan Modra2-48/+276
In a non-pic executable, ELFv2 like other targets, needs to emit a plt entry even for non-call references to functions defined in shared libraries, and define the function on the plt code. * elf64-ppc.c (ppc64_elf_copy_indirect_symbol): Copy pointer_equality_needed flag. (ppc64_elf_check_relocs): For ELFv2 arrange to emit plt entries for references to functions in shared libraries on non-call relocs. (readonly_dynrelocs): Split into function of the same name and.. (maybe_set_textrel): ..this new function. Update call. (ppc64_elf_adjust_dynamic_symbol): Don't emit dynrelocs for ELFv2 in most cases if we have a plt entry. Use new readonly_relocs. (allocate_dynrelocs): For ELFv2, don't allocate dynreloc space for ifunc in static executables. (size_global_entry_stubs): New function. (ppc64_elf_size_dynamic_sections): Call size_global_entry_stubs. Save end of glink branch table. (ppc64_elf_hash_symbol): New function. (build_global_entry_stubs): New function. (ppc64_elf_build_stubs): Call build_global_entry_stubs. Adjust glink sizing. (ppc64_elf_relocate_section): Tidy plt16/32/64 reloc code. (ppc64_elf_finish_dynamic_symbol): For ELFv2, adjust symbols defined on plt code.
