2016-11-27[Darwin] fix PR67710 by updating 'as' specs to handle newer assembler versions.iains
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. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@242898 138bc75d-0d04-0410-961f-82ee72b054a4

2016-10-10Always support float128 on ia64 (PR target/77586).jsm28
Bug 77586, and previously <https://gcc.gnu.org/ml/gcc-bugs/2016-08/msg03233.html>, reports ia64-elf failing to build because of float128_type_node being NULL, but being used by the back end for __float128. The global float128_type_node is only available conditionally, if target hooks indicate TFmode is not only available as a scalar mode and of the right format, but also supported in libgcc. The back-end support, however, expects the type always to be available for __float128 even if the libgcc support is missing. Although a target-specific node could be restored in the case where libgcc support is missing, it seems better to address the missing libgcc support. Thus, this patch enables TFmode soft-fp in libgcc globally for all ia64 targets. Support for XFmode in libgcc (that is, for libgcc2.c XFmode functions, not soft-fp) is also enabled for all ia64 targets so that ia64 no longer needs to define the TARGET_LIBGCC_FLOATING_MODE_SUPPORTED_P hook. I've confirmed that ia64-elf builds cc1 with this patch and it passes -fself-test. I have not otherwise tested the patch. It's plausible that ia64-elf and ia64-freebsd might work as-is, but ia64-vms probably needs further changes, by someone familiar with VMS shared libraries, to implement an equivalent of ia64/t-softfp-compat in that case (avoiding conflicts between __divtf3 from soft-fp and the old alias for __divxf3).

2016-09-07Correct libgcc complex multiply excess precision handling (PR libgcc/77519).jsm28
libgcc complex multiply is meant to eliminate excess precision from certain internal values by forcing them to memory in exactly those cases where the type has excess precision. But in https://gcc.gnu.org/ml/gcc-patches/2014-09/msg01894.html I accidentally inverted the logic so that values get forced to memory in exactly the cases where it's not needed. (This is a pessimization in the no-excess-precision case, in principle could lead to bad results depending on code generation in the excess-precision case. Note: I do not have a test demonstrating bad results.) Bootstrapped with no regressions on x86_64-pc-linux-gnu.

2016-08-26Always support float128 on x86.jsm28
In <https://gcc.gnu.org/ml/gcc-bugs/2016-08/msg03233.html>, Nick reported i386-elf and ia64-elf failing to build because of float128_type_node being NULL, but being used by the back end for __float128. The global float128_type_node is only available conditionally, if target hooks indicate TFmode is not only available as a scalar mode and of the right format, but also supported in libgcc. The back-end support, however, expects the type always to be available for __float128 even if the libgcc support is missing. Although a target-specific node could be restored in the case where libgcc support is missing, it seems better to address the missing libgcc support. Thus, this patch enables TFmode soft-fp in libgcc globally for all x86 targets - the only special cases needed being for targets that use soft-fp for SFmode and DFmode, one of which already had the support for TFmode as well (so I based the i[34567]86-*-rtems* configuration on that present for i[34567]86-*-elfiamcu). The i386 implementation of TARGET_LIBGCC_FLOATING_MODE_SUPPORTED_P is then removed as no longer needed. I can provide such a patch for ia64 if useful, but am not in a position to test it (and while I'm reasonably confident that enabling this support would be right for ia64-elf and ia64-freebsd, I've no real idea if enabling libgcc support for TFmode, with or without also enabling it for XFmode, would be safe for ia64-vms).

2016-08-16Update soft-fp from glibc (PR libgcc/77265).jsm28
This patch updates soft-fp from glibc, bringing in the fix for PR libgcc/77265, XFmode extension to TFmode wrongly turning an infinity into a NaN. A test for that bug is added.
