2021-12-24Darwin: Update rules for handling alignment of globals.Iain Sandoe1-0/+14
The current rule was too strict and has not been required since Darwin11. This relaxes the constraint to allow up to 2^28 alignment for non-common entities. Common is still restricted to a maximum aligment of 2^15. When the host is an older version of Darwin ( earlier that 11 ) then the existing constraint is still applied. Note that this is a host constraint not a target one (so that a compilation on 10.7 targeting 10.6 is allowed to use a greater alignment than the tools on 10.6 support). This matches the behaviour of clang. Signed-off-by: Iain Sandoe <iain@sandoe.co.uk> gcc/ChangeLog: * config.gcc: Emit L2_MAX_OFILE_ALIGNMENT with suitable values for the host. * config/darwin.c (darwin_emit_common): Error for alignment values > 32768. * config/darwin.h (MAX_OFILE_ALIGNMENT): Rework to use the configured L2_MAX_OFILE_ALIGNMENT. gcc/testsuite/ChangeLog: * gcc.dg/darwin-aligned-globals.c: New test. * gcc.dg/darwin-comm-1.c: New test. * gcc.dg/attr-aligned.c: Amend for new alignment values on Darwin. * gcc.target/i386/pr89261.c: Likewise.
2021-12-22arm: Declare MVE types internally via pragmaMurray Steele1-2/+2
Move the implementation of MVE ACLE types from arm_mve_types.h to inside GCC via a new pragma, which replaces the prior type definitions. This allows for the types to be used internally for intrinsic function definitions. gcc/ChangeLog: * config.gcc (arm*-*-*): Add arm-mve-builtins.o to extra_objs. * config/arm/arm-c.c (arm_pragma_arm): Handle "#pragma GCC arm".

2021-12-18Darwin: Future-proof and homogeneize detection of darwin versionsFrançois-Xavier Coudert1-2/+2
The current GCC branch will become 12.1.0, which will be the stable version of GCC when the next macOS version is released. There are some places in GCC that don’t handle darwin22 as a version, so we need to future-proof it (gcc/config.gcc and gcc/config/darwin-driver.c). We align that code with what Apple clang does, i.e. accept all potential major macOS versions until 99. This patch also homogenises the handling of darwin version numbers, where the majority of places use darwin2*, but some used darwin2[0-9]*. Since there never was a darwin2.x version, the two are equivalent, and we prefer the simpler darwin2* gcc/ChangeLog: * config/darwin-driver.c: Make version code more future-proof. * config.gcc: Homogeneize darwin versions. * configure.ac: Homogeneize darwin versions. * configure: Regenerate. gcc/testsuite/ChangeLog: * gcc.dg/darwin-minversion-link.c: Test darwin21. * obj-c++.dg/cxx-ivars-3.mm: Homogeneize darwin versions. * obj-c++.dg/objc-gc-3.mm: Homogeneize darwin versions. * objc.dg/objc-gc-4.m: Homogeneize darwin versions.
2021-12-09Provide vxworks alternate stdint.h during the buildOlivier Hainque1-9/+2
This change arranges to provide the vxworks alternate stdint.h at build time instead of at install time, so it is used instead of the system one while building the libraries. This is a lot more consistent and helps the build on configurations where the system does not come with stdint.h at all. The change uses a similar mechanism as the one previsouly introduced for glimits.h and takes the opportunity to simplify the glimits.h command to use an automatic variable. This introduces an indirect dependency on the VxWorks version.h for vxcrtstuff objects, for which we then need to apply the same tricks as for libgcc2 regarding include paths (to select the system header instead of the gcc one). 2021-02-12 Olivier Hainque <hainque@adacore.com> Rasmus Villemoes <rv@rasmusvillemoes.dk> gcc/ * Makefile.in (T_STDINT_GCC_H): New variable, path to stdint-gcc.h that a target configuration may override when use_gcc_stdint is "provide".

2021-11-10rs6000: Remove LINK_OS_EXTRA_SPEC{32,64} from --with-advance-toolchainLucas A. M. Magalhaes1-10/+0
Historically this was added to fill gaps from ld.so.cache on early AT releases. This now are just causing errors and rework. Since AT5.0 the AT's ld.so is using a correctly configured ld.so.cache and sets the DT_INTERP to AT's ld.so. This two factors are sufficient for an AT builded program to get the correct libraries. GCC congured with --with-advance-toolchain has issues building GlibC releases because it adds DT_RUNPATH to ld.so and that's unsupported. 2021-11-10 Lucas A. M. Magalhães <lamm@linux.ibm.com> gcc/ * config.gcc (powerpc*-*-*): Remove -rpath from --with-advance-toolchain.

2021-10-26rs6000: Fixes for tests including only <x86intrin.h>Paul A. Clarke1-1/+1
Tests which only include <x86intrin.h> expect many other include files to be brought in, but not enough are. Try to increase compatibility with x86 headers by: - Create new immintrin.h, including the analogous subset of intrinsics headers available for powerpc. - Create new x86gprintrin.h, serving exclusively as the umbrella for bmiintrin.h and bmi2intrin.h. - Modify x86intrin.h: - Include new immintrin.h. - Remove mmintrin.h, xmmintrin.h, emmintrin.h, now included indirectly from immintrin.h. - Remove bmiintrin.h, bmi2intrin.h, now included indirectly from x86gprintrin.h (which is now included from immintrin.h). Add the new files to gcc/config.gcc. Also, fix up the testcase that provoked PR102719, which requires Power8 vector support. Fixes commit 29fb1e831bf1c25e4574bf2f98a9f534e5c67665. 2021-10-25 Paul A.

After r12-4432-g7bfe7d634f60b0a9 Darwin fails to bootstrap with D enabled since there is no definition of either DWARF2_DEBUG_INFO or PREFERRED_DEBUGGING_TYPE.

The BPF CO-RE support (commit 8bdabb37549f12ce727800a1c8aa182c0b1dd42a) mistakenly overwrote bpf-*-* extra_headers in config.gcc, causing bpf-helpers.h to not be installed.

This removes the support for vax-openbsd which has been discontinued after the OpenBSD 5.9 release and which has no supported gas or GNU ld configuration [anymore].

2021-09-15Remove m68k-openbsd supportRichard Biener1-11/+1
This removes m68k-openbsd as a valid configuration, according to openbsd.org m68k-openbsd [on the mac] was discontinued after the 5.1 release. The configuration is also not (or no longer) supported by gas and GNU ld so I could not figure whether it is still a.out (I suspect it is). But first and foremost the target only supports STABS as a debugging format. 2021-09-13 Richard Biener <rguenther@suse.de> * config.gcc: Remove m68k-openbsd. contrib/ * config-list.mk: Remove m68k-openbsd.
2021-09-13Remove m32r{,le}-*-linux* support from GCCAndrew Pinski1-16/+2
m32r support never made it to glibc and the support for the Linux kernel was removed with 4.18. It does not remove much but no reason to keep around a port which never worked or one which the support in other projects is gone. OK? Checked to make sure m32r-linux and m32rle-linux were rejected when building. contrib/ChangeLog: * config-list.mk: Remove m32r-linux and m32rle-linux from the list. gcc/ChangeLog: * config.gcc: Add m32r-*-linux* and m32rle-*-linux* to the Unsupported targets list.

2021-08-24nvptx: Add a __PTX_SM__ predefined macro based on target ISA.Roger Sayle1-0/+2
This patch adds a __PTX_SM__ predefined macro to the nvptx backend that allows code to check the compute model being targeted by the compiler. This is equivalent to the __CUDA_ARCH__ macro defined by CUDA's nvcc compiler, but to avoid causing problems for source code that checks for that compiler, this macro uses GCC's nomenclature; it's easy enough for users to "#define __CUDA_ARCH__ __PTX_SM__". What might have been a four line patch is actually a little more complicated, as this patch takes the opportunity to upgrade the nvptx backend to use the now preferred nvptx-c.c idiom. 2021-08-24 Roger Sayle <roger@nextmovesoftware.com> Tom de Vries <tdevries@suse.de> gcc/ChangeLog * config.gcc (nvptx-*-*): Define {c,c++}_target_objs. * config/nvptx/nvptx-protos.h (nvptx_cpu_cpp_builtins): Prototype. * config/nvptx/nvptx.h (TARGET_CPU_CPP_BUILTINS): Implement with a call to the new nvptx_cpu_cpp_builtins function in nvptx-c.c. * config/nvptx/t-nvptx (nvptx-c.o): New rule. * config/nvptx/nvptx-c.c: New source file.
