2014-10-30Make soft-fp symbols into compat symbols for powerpc*-*-linux*.Joseph Myers8-10/+171
Continuing preparations for implementing TARGET_ATOMIC_ASSIGN_EXPAND_FENV for powerpc*-*-linux* soft-float and e500, this patch makes soft-fp symbols used for those targets into compat symbols when building with glibc >= 2.19, so that they are only in shared libgcc for existing binaries requiring them, not in static libgcc and not available for new links using shared libgcc. Instead, new links will get the symbols from libc, which has exported all of them since 2.19. (Actually all the symbols were exported from glibc since 2.4, but some of them were exported by glibc as compat symbols only - because of a confusion between deliberately present soft-fp symbols and old accidental reexports of libgcc functions from glibc 2.0 - until 2.19.) This allows user floating-point arithmetic to interoperate properly with the state handled by <fenv.h> functions, whether software state (for soft-float; TLS variables that don't form a public part of glibc's ABI, so can only be accessed directly by functions within glibc) or hardware state (for e500 - the copies of the soft-fp functions in glibc being built to interoperate with the hardware state whereas those in libgcc aren't). Previously only glibc's own functions, and those operations done in hardware on e500, properly worked with that state, not direct floating-point arithmetic operations that were implemented in software. The intended next step is the actual TARGET_ATOMIC_ASSIGN_EXPAND_FENV implementation. The test of glibc >= 2.19 uses the same --with-glibc-version configure option as in the gcc/ directory (but differently implemented; in gcc/ the fallback is to examine headers to find the version, while in libgcc/ we can use compile for the target and so use AC_COMPUTE_INT). The TARGET_ATOMIC_ASSIGN_EXPAND_FENV implementation will also only do anything for glibc >= 2.19, as it will depend on generating calls to functions __atomic_feholdexcept __atomic_feclearexcept __atomic_feupdateenv that were added in 2.19 for that purpose (even for e500, inline code is not readily possible because of the need to make prctl syscalls from the implementation of these functions). In order to make symbols compat symbols, the soft-fp files need wrapping with generated wrappers including asm .symver directives, which need to name the symbol version in question. This is extracted by an awk script from an intermediate stage of generating the .map file for linking libgcc (that .map itself depends on the objects that go into the library, so can't be used for this purpose as that would mean a circular dependency); the extraction is not fully general regarding the features available in .map generation, but suffices for the present purpose. It would make sense for hardfp.c symbols to be compat symbols as well (in the cases where hardfp.c gets used, the functions in question should not be used for new links), but this isn't required for the present purpose, which is only concerned with ensuring that where functions that should be affected by rounding modes or exceptions get used, those functions are actually affected by those rounding modes or exceptions. Tested with no regressions with cross to powerpc-linux-gnu (soft-float); c11-atomic-exec-5.c moves from UNSUPPORTED to FAIL, as expected, now that floating-point arithmetic in user programs uses the same state as <fenv.h> functions, so the fenv_exceptions test passes, but TARGET_ATOMIC_ASSIGN_EXPAND_FENV isn't yet implemented. (For e500, c11-atomic-exec-5.c was already FAILing, as enough operations worked with the hardware state for the fenv_exceptions effective target test to pass.) Also verified that the exported symbols and versions are unchanged, with the expected symbols becoming compat symbols at the same versions, and that with --with-glibc-version=2.18 the symbols remain normal rather than compat symbols. * Makefile.in (libgcc.map.in): New target.

2014-10-29Optimize powerpc*-*-linux* e500 hardfp/soft-fp use.Joseph Myers6-3/+92
Continuing the cleanups of libgcc soft-fp configuration for powerpc*-*-linux* in preparation for implementing TARGET_ATOMIC_ASSIGN_EXPAND_FENV for soft-float and e500, this patch optimizes the choice of which functions to build for the e500 cases. For e500v2, use of hardfp is generally right, except that calls to __unordsf2 and __unorddf2 are actually generated by GCC from __builtin_isunordered and so they need to be implemented with soft-fp to avoid recursively calling themselves. For e500v1, hardfp is right for SFmode (except for __unordsf2) but soft-fp for DFmode (and when using soft-fp, as usual it's best for the conversions between DFmode and integers all to come directly from soft-fp rather than some coming from libgcc2.c). Thus, new variables hardfp_exclusions and softfp_extras are added that configurations using t-hardfp and t-softfp can use to achieve the desired effect of selectively mixing the two sources of functions. Tested with no regressions for crosses to powerpc-linux-gnuspe (both e500v1 and e500v2); also checked that the same set of symbols and versions is exported from shared libgcc before and after the patch. * config/t-hardfp (hardfp_exclusions): Document new variable for user to define.

2014-10-25Optimize powerpc*-*-linux* 32-bit classic hard/soft float hardfp/soft-fp use.Joseph Myers4-2/+71
Continuing the cleanups of libgcc soft-fp configuration for powerpc*-*-linux* in preparation for implementing TARGET_ATOMIC_ASSIGN_EXPAND_FENV for soft-float and e500, this patch optimizes the choice of which functions to build for the 32-bit classic hard-float and soft-float cases. (e500 will be dealt with in a separate patch which will need to add new features to t-hardfp and t-softfp; this patch keeps the status quo for e500.) For hard-float, while the functions in question are part of the libgcc ABI there is no need for them to contain software floating point code: no newly built code should use them, and if anything does use them it's most efficient (space and speed) for them to pass straight through to floating-point hardware instructions; this case is made to use t-hardfp to achieve that. For soft-float, direct use of soft-fp functions for operations involving DImode or unsigned integers is more efficient than using the libgcc2.c versions of those operations to convert to operations on other types (which then end up calling soft-fp functions for those other types, possibly more than once); this case is thus stopped from using t-softfp-excl. (A future patch will stop the e500 cases from using t-softfp-excl as well.) Tested with no regressions for crosses to powerpc-linux-gnu (soft float and classic hard float); also checked that the same set of symbols and versions is exported from shared libgcc before and after the patch. * configure.ac (ppc_fp_type): Set variable on powerpc*-*-linux*. * configure: Regenerate. * config.host (powerpc*-*-linux*): Use $ppc_fp_type to determine additions to tmake_file. Use t-hardfp-sfdf and t-hardfp instead of soft-fp for 32-bit classic hard float. Do not use t-softfp-excl for soft float. From-SVN: r216687
2014-10-22Do not build soft-fp code at all for powerpc64-linux-gnu.Joseph Myers3-4/+11
When I added support for using soft-fp in libgcc <https://gcc.gnu.org/ml/gcc-patches/2006-03/msg00689.html>, libgcc configuration was still done in the gcc/ directory, meaning that the variables set in makefile fragments could not depend on the multilib being built. Thus, building the soft-fp code for powerpc64-linux-gnu was disabled in the same way as had been done with fp-bit: the code was built, but with #ifndef __powerpc64__ wrappers around it so that the resulting objects were empty. Now that libgcc configuration is done in the toplevel libgcc directory, such uses of softfp_wrap_start / softfp_wrap_end are better replaced by configure-time conditionals that determine whether to use soft-fp for a given multilib. This patch does so for powerpc*-*-linux*. The same would appear to apply to powerpc*-*-freebsd* (using rs6000/t-freebsd64), but I have not made any changes there. t-ppc64-fp is also used by AIX targets, but they don't use soft-fp anyway so the changes are of no consequence to them. The same principle of replacing softfp_wrap_start / softfp_wrap_end with configure-time conditionals also applies to softfp_exclude_libgcc2, which was intended for cases where soft-fp is being used on hard-float multilibs and so it is desirable on those multilibs for a few functions to come from libgcc2.c rather than soft-fp (but the soft-fp versions would be more efficient on soft-float multilibs). Now we have hardfp.c and t-hardfp, those are better to use in that case, to minimize the size of the bulk of the functions that are only present for ABI compatibility and should never be called by newly compiled code. I intend followup patches to switch 32-bit hard-float multilibs to use t-hardfp as far as possible (for all non-libgcc2.c operations for classic hard float; for all except __unord* for e500v2; for all SFmode operations except __unordsf2 for e500v1). After that will come making the soft-fp operations, in the remaining cases for which they are built because they are actually needed for code compiled by current GCC, into compat symbols when building for glibc 2.19 or later, so that the glibc versions (with exception and rounding mode support) get used instead (2.19 or later is needed for all the functions to be exported from glibc as non-compat symbols). In turn, that is required before implementing TARGET_ATOMIC_ASSIGN_EXPAND_FENV for soft-float and e500, as that can only be properly effective when GCC-compiled code is actually interoperating correctly with the exception and rounding mode state used by <fenv.h> functions. Tested with no regressions with cross to powerpc64-linux-gnu (in addition, verified that stripped libgcc_s.so.1 is identical before and after the patch). * config.host (powerpc*-*-linux*): Only use soft-fp for 32-bit configurations. * config/rs6000/t-ppc64-fp (softfp_wrap_start, softfp_wrap_end): Remove variables.
