2022-10-04aarch64: Define __ARM_FEATURE_RCPCRichard Sandiford5-6/+28
https://github.com/ARM-software/acle/pull/199 adds a new feature macro for RCPC, for use in things like inline assembly. This patch adds the associated support to GCC. Also, RCPC is required for Armv8.3-A and later, but the armv8.3-a entry didn't include it. This was probably harmless in practice since GCC simply ignored the extension until now. (The GAS definition is OK.) gcc/ * config/aarch64/aarch64.h (AARCH64_ISA_RCPC): New macro. * config/aarch64/aarch64-arches.def (armv8.3-a): Include RCPC. * config/aarch64/aarch64-cores.def (thunderx3t110, zeus, neoverse-v1) (neoverse-512tvb, saphira): Remove RCPC from these Armv8.3-A+ cores. * config/aarch64/aarch64-c.cc (aarch64_update_cpp_builtins): Define __ARM_FEATURE_RCPC when appropriate. gcc/testsuite/ * gcc.target/aarch64/pragma_cpp_predefs_1.c: Add RCPC tests.

2022-10-04openmp: Add begin declare target supportJakub Jelinek18-75/+328
The following patch adds support for the begin declare target construct, which is another spelling for declare target construct without clauses (where it needs paired end declare target), but unlike that one accepts clauses. This is an OpenMP 5.1 feature, implemented with 5.2 clarification because in 5.1 we had a restriction in the declare target chapter shared by declare target and begin declare target that if there are any clauses specified at least one of them needs to be to or link. But that was of course meant just for declare target and not begin declare target, because begin declare target doesn't even allow to/link/enter clauses. In addition to that, the patch also makes device_type clause duplication an error (as stated in 5.1) and similarly makes declare target with just device_type clause an error rather than warning. What this patch doesn't do is: 1) OpenMP 5.1 also added an indirect clause, we don't support that neither on declare target nor begin declare target and I couldn't find it in our features pages (neither libgomp.texi nor web) 2) I think device_type(nohost)/device_type(host) support can't work for variables (in 5.0 it only talked about procedures so this could be also thought as 5.1 feature that we should just add to the list and implement) 3) I don't see any use of the "omp declare target nohost" attribute, so I'm not sure if device_type(nohost) works at all 2022-10-04 Jakub Jelinek <jakub@redhat.com> gcc/c-family/ * c-omp.cc (c_omp_directives): Uncomment begin declare target entry. gcc/c/ * c-lang.h (struct c_omp_declare_target_attr): New type.

2022-10-04Convert nonzero mask in irange to wide_int.Aldy Hernandez3-171/+130
The reason the nonzero mask was kept in a tree was basically inertia, as everything in irange is a tree. However, there's no need to keep it in a tree, as the conversions to and from wide ints are very annoying. That, plus special casing NULL masks to be -1 is prone to error. I have not only rewritten all the uses to assume a wide int, but have corrected a few places where we weren't propagating the masks, or rather pessimizing them to -1. This will become more important in upcoming patches where we make better use of the masks. Performance testing shows a trivial improvement in VRP, as things like irange::contains_p() are tied to a tree. Ughh, can't wait for trees in iranges to go away. gcc/ChangeLog: * value-range-storage.cc (irange_storage_slot::set_irange): Remove special case. * value-range.cc (irange::irange_set): Adjust for nonzero mask being a wide int.

2022-10-03libstdc++: Filter out unconditional <stdio.h> default includeArsen Arsenović2-8/+26
_AC_INCLUDES_DEFAULT_REQUIREMENTS including <stdio.h> when checking for stdint.h has prevented proper detection of whether stdint.h is present, since it'd poison the cache variables with test results failing due to <stdio.h> failing to include. As a solution, for autoconf versions under 2.70, we filter out that bit of code from ac_includes_default. This issue was fixed in autoconf-2.70. This also applies to various other headers, but was noticed when looking into why HAVE_STDINT_H was misdefined. libstdc++-v3/ChangeLog: * configure.ac: Remove any lines that unconditionally include <stdio.h> from ac_includes_default, when running Autoconf <2.70. * configure: Regenerate.
2022-10-03libstdc++: Make _GLIBCXX_HOSTED respect -ffreestanding [PR103626]Jonathan Wakely6-7/+7
This allows the library to switch to freestanding mode when compiling with the -ffreestanding flag. This means you don't need a separate libstdc++ build configured with --disable-hosted-libstdcxx in order to compile for a freestanding environment.

2022-10-03vect: while_ult for integer masksAndrew Stubbs3-6/+35
Add a vector length parameter needed by amdgcn without breaking aarch64. All amdgcn vector masks are DImode, regardless of vector length, so we can't tell what length is implied simply from the operator mode. (Even if we used different integer modes there's no mode small enough to differenciate a 2 or 4 lane mask). Without knowing the intended length we end up using a mask with too many lanes enabled, which leads to undefined behaviour.. The extra operand is not added for vector mask types so AArch64 does not need to be adjusted. gcc/ChangeLog: * config/gcn/gcn-valu.md (while_ultsidi): Limit mask length using operand 3. * doc/md.texi (while_ult): Document new operand 3 usage. * internal-fn.cc (expand_while_optab_fn): Set operand 3 when lhs_type maps to a non-vector mode.

2022-10-03c: Adjust LDBL_EPSILON for C2x for IBM long doubleJoseph Myers3-1/+44
C2x changes the <float.h> definition of *_EPSILON to apply only to normalized numbers. The effect is that LDBL_EPSILON for IBM long double becomes 0x1p-105L instead of 0x1p-1074L. There is a reasonable case for considering this a defect fix - it originated from the issue reporting process (DR#467), though it ended up being resolved by a paper (N2326) for C2x rather than through the issue process, and code using *_EPSILON often needs to override the pre-C2x value of LDBL_EPSILON and use something on the order of magnitude of the C2x value instead. However, I've followed the conservative approach of only making the change for C2x and not for previous standard versions (and not for C++, which doesn't have the C2x changes in this area). The testcases added are intended to be valid for all long double formats. The C11 one is based on gcc.target/powerpc/rs6000-ldouble-2.c (and when we move to a C2x default, gcc.target/powerpc/rs6000-ldouble-2.c will need an appropriate option added to keep using an older language version). Tested with no regressions for cross to powerpc-linux-gnu. gcc/c-family/ * c-cppbuiltin.cc (builtin_define_float_constants): Do not special-case __*_EPSILON__ setting for IBM long double for C2x. gcc/testsuite/ * gcc.dg/c11-float-7.c, gcc.dg/c2x-float-12.c: New tests.
2022-10-03libstdc++: Fix tests broken by C++23 P2266R3 "Simpler implicit move"Jonathan Wakely2-2/+2
In C++23 mode these tests started to FAIL because an rvalue reference parameter can no longer be bound to an lvalue reference return type. As confirmed by Ville (who added these tests) the problem overloads are not intended to be called, and only exist to verify that they don't interfere with the intended behaviour. This changes the function bodies to just throw, so that the tests will fail if the function is called. libstdc++-v3/ChangeLog: * testsuite/27_io/basic_ostream/inserters_other/char/6.cc: Change body of unused operator<< overload to throw if called. * testsuite/27_io/basic_ostream/inserters_other/wchar_t/6.cc: Likewise.

Currently if we have a range of [0,0] and we set the nonzero bits to 1, the current code pessimizes the range to [0,1] because it assumes the range is [1,1] plus the possibility of 0.

2022-10-02Adjust LIBGCC2_INCLUDES for VxWorks and augment commentOlivier Hainque1-8/+28
Investigating the reasons for libgcc build failures in a canadian context, orthogonally to the recent update of vxcrtstuff, exposed interesting differences in the way include search paths are managed between a regular Linux->VxWorks cross build and a canadian setup building a Windows->VxWorks toolchain in a Linux environment. This change augments the comment attached to LIBGCC2_INCLUDE in libgcc/config/t-vxworks to better describe the parameters at play. It also adjusts the addition of options for gcc/include and gcc/include-fixed to minimize the actual differences for libgcc in the two kinds of configurations. 2022-03-06 Olivier Hainque <hainque@adacore.com> libgcc/ * config/t-vxworks (LIBGCC2_INCLUDE): Augment comment.

2022-10-02Define GCC_DRIVER_HOST_INITIALIZATION for VxWorks targetsMarc Poulhiès4-0/+109
We need to perform static links by default on VxWorks, where the use of shared libraries involves unusual steps compared to standard native systems. This has to be conveyed before the lang_specific_driver code gets invoked (in particular for g++), so specs aren't available. This change defines the GCC_DRIVER_HOST_INITIALIZATION macro for VxWorks, to insert a -static option in case the user hasn't provided any explicit indication on the command line of the kind of link desired. While a HOST macro doesn't seem appropriate to control a target OS driven behavior, this matches other uses and won't conflict as VxWorks is not supported on any of the other configurations using this macro. gcc/ * config/vxworks-driver.cc: New. * config.gcc (*vxworks*): Add vxworks-driver.o in extra_gcc_objs. * config/t-vxworks: Add vxworks-driver.o. * config/vxworks.h (GCC_DRIVER_HOST_INITIALIZATION): New.

Within gthr-vxworks.h, we prevent C++ errors from missing declarations in some system headers by prepending their inclusion with a #pragma GCC diagnostic ignored "-Wstrict-prototypes" But Wstrict-prototypes is internally registered as valid for C/ObjC only, not C++, and this trick in turn triggers a Wpragma warning with -Wsystem-headers. This change just arranges to ignore the secondary warning locally. 2021-02-03 Olivier Hainque <hainque@adacore.com> * config/gthr-vxworks.h: Prevent Wpragma warning for the pragma diagnostics on Wstrict-prototypes.
2022-10-02Refine guard for vxworks crtstuff specOlivier Hainque1-5/+4
Working on the reintroduction of shared libraries support (and of modules depending on shared libraries) exposed a few test failures of simple c++ constructor tests on arm-vxworks7r2. Investigation revealed that we were not linking the crtstuff objects as needed from a compiler configured not to have shared libs support, because of the ENABLE_SHARED_LIBGCC guard in this piece of vxworks.h: /* Setup the crtstuff begin/end we might need for dwarf EH registration and/or INITFINI_ARRAY support for shared libs. */ #if (HAVE_INITFINI_ARRAY_SUPPORT && defined(ENABLE_SHARED_LIBGCC)) \ || (DWARF2_UNWIND_INFO && !defined(CONFIG_SJLJ_EXCEPTIONS)) #define VX_CRTBEGIN_SPEC "%{!shared:vx_crtbegin.o%s;:vx_crtbeginS.o%s}" crtstuff initfini array support is meant to be leveraged for constructors regardless of whether the compiler also happens to be configured with shared library support, so the guard on ENABLE_SHARED_LIBGCC here is inappropriate. This change just removes it, 2022-09-30 Olivier Hainque <hainque@adacore.com> gcc/ * config/vxworks.h (VX_CRTBEGIN_SPEC, VX_CRTEND_SPEC): If HAVE_INITFINI_ARRAY_SUPPORT, pick crtstuff objects regardless of ENABLE_SHARED_LIBGCC.
