2016-11-27[Darwin] fix PR67710 by updating 'as' specs to handle newer assembler versions.Iain Sandoe1-0/+7
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.

2016-11-27[Darwin, config] Arrange for ld64 to be detected as Darwin's linker.Iain Sandoe1-0/+12
This is an initial patch in a series that converts Darwin's configury to detect ld64 features, rather than the current process of hard-coding them on target system version. A ld64-compatible linker is currently required and assumed by Darwin. If a DEFAULT_LINKER is set via --with-ld= then this will be tested to see if it is ld64. The ld64 version is determined for the chosen ld and this is exported for use in setting a default value for -mtarget-linker (needed for run-time code-gen changes to section choices). The support for -rdynamic is converted to be detected at config time, or by the ld64 version if that is found. gcc/ 2016-11-27 Iain Sandoe <iain@codesourcery.com> PR target/71767 * configure.ac (with-ld64): New var, set for Darwin, set on detection of ld64, gcc_cv_ld64_export_dynamic: New, New test. * config/darwin.h: Use LD64_HAS_DYNAMIC export.

Extend this attribute to cover long double ABIs, for 64-bit too. This patch also corrects an error that crept in to code setting rs6000_passes_float. See the added comment.

There are extensions to x86-64 psABI: https://groups.google.com/forum/#!topic/x86-64-abi/de5_KnLHxtI and i386 psABI: https://groups.google.com/forum/#!topic/ia32-abi/awsRSvJOJfs to call tls_get_addr via GOT. X86 assembler and linker in binutils 2.27 implemented call *__tls_get_addr@GOTPCREL(%rip) in 64-bit and call *___tls_get_addr@GOT(%reg) in 32-bit to access global and local thread loal variables in shared library. We check if 32-bit x86 assembler and linker work with call *___tls_get_addr@GOT(%reg) as 32-bit and 64-bit assembler and linker are enabled togther.

2014-12-04x86-64: Optimize access to globals in PIE with copy relocSriraman Tallam1-0/+6
Normally, with -fPIE/-fpie, GCC accesses globals that are extern to the module using the GOT. This is two instructions, one to get the address of the global from the GOT and the other to get the value. If it turns out that the global gets defined in the executable at link-time, it still needs to go through the GOT as it is too late then to generate a direct access. Examples: foo.cc ------ int a_glob; int main () { return a_glob; // defined in this file } With -O2 -fpie -pie, the generated code directly accesses the global via PC-relative insn: 5e0 <main>: mov 0x165a(%rip),%eax # 1c40 <a_glob> foo.cc ------ extern int a_glob; int main () { return a_glob; // defined in this file } With -O2 -fpie -pie, the generated code accesses global via GOT using two memory loads: 6f0 <main>: mov 0x1609(%rip),%rax # 1d00 <_DYNAMIC+0x230> mov (%rax),%eax This is true even if in the latter case the global was defined in the executable through a different file. Some experiments on google benchmarks shows that the extra memory loads affects performance by 1% to 5%. Solution - Copy Relocations: When the linker supports copy relocations, GCC can always assume that the global will be defined in the executable. For globals that are truly extern (come from shared objects), the linker will create copy relocations and have them defined in the executable. Result is that no global access needs to go through the GOT and hence improves performance. This optimization only applies to undefined, non-weak global data. Undefined, weak global data access still must go through the GOT. This patch checks if linker supports PIE with copy reloc, which is enabled in gold and bfd linker in bininutils 2.25, at configure time and enables this optimization if the linker support is available. gcc/ * configure.ac (HAVE_LD_PIE_COPYRELOC): Defined to 1 if Linux/x86-64 linker supports PIE with copy reloc. * config.in: Regenerated. * configure: Likewise. * config/i386/i386.c (legitimate_pic_address_disp_p): Allow pc-relative address for undefined, non-weak, non-function symbol reference in 64-bit PIE if linker supports PIE with copy reloc. * doc/sourcebuild.texi: Document pie_copyreloc target. gcc/testsuite/ * gcc.target/i386/pie-copyrelocs-1.c: New test. * gcc.target/i386/pie-copyrelocs-2.c: Likewise. * gcc.target/i386/pie-copyrelocs-3.c: Likewise. * gcc.target/i386/pie-copyrelocs-4.c: Likewise. * lib/target-supports.exp (check_effective_target_pie_copyreloc): New procedure.

2014-11-03Implement TARGET_ATOMIC_ASSIGN_EXPAND_FENV for powerpc*-*-linux* soft-float ↵Joseph Myers1-4/+19
and e500. This patch implements support for TARGET_ATOMIC_ASSIGN_EXPAND_FENV for powerpc*-*-linux* soft-float and e500, provided GCC is configured for glibc 2.19 or later on the target. New functions __atomic_feholdexcept, __atomic_feclearexcept and __atomic_feupdateenv were added (to libc) in that glibc version (for powerpc soft-float / e500 only) in order to support this part of C11. For soft-float, libc functions are needed because the floating-point exception state is in TLS variables in libc that aren't directly accessible outside of glibc. For e500, they are also needed because of the prctl syscalls involved in controlling trapping for exceptions and informing the kernel when certain exception flags have been cleared. The actual implementation in GCC is a straightforward matter of calling those functions. Tested with no regressions for cross to powerpc-linux-gnu (soft-float); the c11-atomic-exec-5.c results go from FAIL to PASS. * configure.ac (TARGET_GLIBC_MAJOR, TARGET_GLIBC_MINOR): Define macros. * configure, config.h.in: Regenerate. * config/rs6000/linux.h [TARGET_GLIBC_MAJOR > 2 || (TARGET_GLIBC_MAJOR == 2 && TARGET_GLIBC_MINOR >= 19)] (RS6000_GLIBC_ATOMIC_FENV): New macro. * config/rs6000/linux64.h [TARGET_GLIBC_MAJOR > 2 || (TARGET_GLIBC_MAJOR == 2 && TARGET_GLIBC_MINOR >= 19)] (RS6000_GLIBC_ATOMIC_FENV): New macro. * config/rs6000/rs6000.c (atomic_hold_decl, atomic_clear_decl) (atomic_update_decl): New static variables. (rs6000_atomic_assign_expand_fenv) [RS6000_GLIBC_ATOMIC_FENV]: Generate calls to __atomic_feholdexcept, __atomic_feclearexcept and __atomic_feupdateenv for soft-float and no-FPRs. From-SVN: r217040
