2017-03-10rs6000: float128 on BE and 32-bitSegher Boessenkool4-13/+23
This fixes float128 on BE and on 32-bit. The configure tests need to use -mabi=altivec for 32-bit, since it is not the default there. That also enables the "vector" keyword, used by the tests. To do this it temporarily adds a few flags to the CFLAGS variable. It also fixes a syntax error in the libgcc_cv_powerpc_float128_hw test (the function name was missing in the function declaration). Regenerating config.in (via autoreconf) removed the duplicate definition of HAVE_SOLARIS_CRTS. Finally, this adds a "-mfloat128-hardware requires -m64" test to rs6000.c: all the current patterns need 64-bit registers. Maybe we'll want to add float128 hardware support to 32-bit some day, but certainly not today. * config/rs6000/rs6000.c (rs6000_option_override_internal): Disallow -mfloat128-hardware without -m64. libgcc/ * configure.ac (test for libgcc_cv_powerpc_float128): Temporarily modify CFLAGS.

2017-01-04Make MIPS soft-fp preserve NaN payloads for NAN2008.Joseph Myers2-1/+18
The MIPS sfp-machine.h has an _FP_CHOOSENAN implementation which emulates hardware semantics of not preserving signaling NaN payloads for an operation with two NaN arguments (although that doesn't suffice to avoid sNaN payload preservation in any case with just one NaN argument). However, those are only hardware semantics in the legacy NaN case; in the NAN2008 case, the architecture documentation says hardware preserves payloads in such cases. Furthermore, this implementation assumes legacy NaN semantics, so in the NAN2008 case the implementation actually has the effect of preserving sNaN payloads but not preserving qNaN payloads, when both should be preserved. This patch fixes the code just to copy from the first argument (at the level of libgcc, it's not meaningful which argument is the first and which is the second). Tested for mips64-linux-gnu (soft float, NAN2008) with the glibc math/ tests. * config/mips/sfp-machine.h (_FP_CHOOSENAN): Always preserve NaN payload if [__mips_nan2008]. From-SVN: r244059

2016-11-27[Darwin] fix PR67710 by updating 'as' specs to handle newer assembler versions.Iain Sandoe2-0/+10
A/ Newer versions of ld64 check the min_version command, and newer versions of the system assembler inserts this in response to "-mmacosx-version-min=" on the assembler line. Unless one makes sensible versions, some object is bound to conflict. B/ Additionally, there's a difference in behaviour between "as" and "ld" when presented with xx.yy.zz (ld truncates to xx.yy, as doesn't); net result is that one needs to pass a truncated version to "as". So (if the assembler supports minversion commands) (a) provide a truncated minversion (as asm_macosx_version_min, which is a driver-only var). (b) pass this to "as" (c) Update tests to determine 'HAVE_AS_MMACOSX_VERSION_MIN_OPTION' (Rainer's patch) (d) For some reason the testcases are "run" (it's not obvious they need to be, they are checking compile-time issues) - anyway, to preserve the status quo, I've left them as exec. However, the minimum version that can be code-gened for is target-dependent (there are no released x86 versions before 10.4, for example). To avoid conflicts where the "as" is assuming some minimum, I've set the testversion to 10.5 (which is supported by all the archs we have) (e) We need to ensure that libgcc and crts are generated with a sufficiently old minversion not to conflict. gcc/ 2016-11-27 Iain Sandoe <iain@codesourcery.com> Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE> PR target/67710 * config.in: Regenerate * config/darwin-driver.c (darwin_driver_init): Emit a version string for the assembler. * config/darwin.h(ASM_MMACOSX_VERSION_MIN_SPEC): New, new tests. * config/darwin.opt(asm_macosx_version_min): New. * config/i386/darwin.h: Handle ASM_MMACOSX_VERSION_MIN_SPEC. * configure: Regenerate * configure.ac: Check for mmacosx-version-min handling. gcc/testsuite/ 2016-11-27 Iain Sandoe <iain@codesourcery.com> Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE> Dominique d'Humieres <dominiq@lps.ens.fr> PR target/67710 * gcc.dg/darwin-minversion-1.c: Update min version check. * gcc.dg/darwin-minversion-2.c: Likewise. * gcc.dg/darwin-minversion-3.c: Likewise. libgcc/ 2016-11-27 Iain Sandoe <iain@codesourcery.com> Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE> PR target/67710 * config/t-darwin: Default builds to 10.5 codegen.
