2023-05-21Darwin, libgcc : Adjust min version supported for the OS.Iain Sandoe6-8/+63
Tools from later versions of the OS deprecate or fail to support earlier OS revisions.

2022-09-19Fix PR target/99184: Wrong cast from double to 16-bit and 32-bit intsGeorg-Johann Lay1-50/+0
this patch fixed PR target/99184 which incorrectly rounded during 64-bit (long) double to 16-bit and 32-bit integers. The patch just removes the respective roundings from libf7-asm.sx::to_integer and ::to_unsigned. Luckily, LibF7 does nowhere use respective functions internally, the only user is in libf7.c::f7_exp which reads f7_round (qq, qq); int16_t q = f7_get_s16 (qq); so that f7_get_s16() operates on an already rounded value, and therefore this code works unaltered with or without rounding in to_integer. PR target/99184 libgcc/config/avr/libf7/ * libf7-asm.sx (to_integer, to_unsigned): Don't round 16-bit and 32-bit integers. (cherry picked from commit 0b5b8ac5cb7fe92dd17ae8bd7de84640daa59e84)

2021-12-17libgcc, Darwin: Add missing build dependencies.Iain Sandoe4-7/+12
There was a race condition where the link for the new shared EH library (only used on earlier Darwin) could fail because the new crts had not been copied to the gcc directory. This can cause a build failure (although currently only seen on powerpc-darwin). Fixed by adding specific dependency on the crts and on the multi target. We also add the declaration header for the Darwin10 unwinder shim to the powerpc cases, since we build that there for Rosetta use. Signed-off-by: Iain Sandoe <iain@sandoe.co.uk> libgcc/ChangeLog: * config.host: Add shim declaration header to powerpc*-darwin builds. * config/rs6000/t-darwin-ehs: Remove dependency on the powerpc end file. * config/t-darwin-ehs: Add dependencies to the shared unwinder objects. * config/t-slibgcc-darwin: Add extra_parts to the dependencies for the shared EH lib.

2021-12-13Remove ppc*-vxworks7* inadequate libgcc Makefile fragmentsOlivier Hainque1-1/+1
t-linux assigns .so version numbers to a set of symbols, some of which aren't included the VxWorks libgcc on powerpc (from ibm-ldouble.c, in particular). t-slibgcc-libgcc yields a kind of .so file that the default loader can't handle. This sort of extension to tmake_file for shared libs will be better handled in a grouped fashion for all targets anyway. 2021-12-13 Olivier Hainque <hainque@adacore.com> * config.host (powerpc*-*-vxworks7*): Remove rs6000/t-linux and t-slibgcc-libgcc from tmake_file.

2021-12-13Tigthen libc_internal and crtstuff for VxWorks shared objectsFrederic Konrad2-5/+81
This change tightens and documents the use of libc_internal, then strengthens the VxWorks crtstuff objects for the support of shared libraries. In particular: - Define __dso_handle, which libstdc++.so requires, - Provide _init and _fini functions to run through the init/fini arrays for shared libs in configurations which HAVE_INITFINI_ARRAY_SUPPORT. The init/fini functions are provided by libc_internal.a for static links but with slightly different names and we don't want to risk dragging other libc_internal contents in the closure accidentally so make sure we don't link with it. As for the !vxworks crtstuff, the new shared libs specific bits are conditioned by a CRTSTUFFS_O macro, for which we provide new Makefile fragment. The bits to actually use the fragment and the shared objects will be added by a forthcoming change, as part of a more general configury update for shared libs. The change also adds guards the eh table registration code in vxcrtstuff so the objects can be used for either init/fini or eh tables independently. 2021-12-07 Fred Konrad <konrad@adacore.com> Olivier Hainque <hainque@adacore.com> gcc/ * config/vxworks.h (VXWORKS_BASE_LIBS_RTP): Guard -lc_internal on !shared+!non-static and document. (VXWORKS_LIB_SPEC): Remove the bits intended to drag the init/fini functions from libc_internal in the shared lib case. (VX_CRTBEGIN_SPEC/VX_CRTEND_SPEC): Use vxcrtstuff objects also in configurations with shared lib and INITFINI_ARRAY support. libgcc/ * config/t-vxcrtstuffS: New Makefile fragment. * config/vxcrtstuff.c: Provide __dso_handle. Provide _init/_fini functions for INITFINI_ARRAY support in shared libs and guard the definition of eh table registration functions on conditions indicating they are needed.
2021-12-13Preserve cpu specific CRTSTUFF_T_CFLAGS on powerpc-vxworks7Olivier Hainque2-2/+5
The unconditional assignment performed in t-vxworks to handle include flags currently overrides what specific cpu ports had for the regular (!vxworks) crtstuff objects. This was not done on purpose and the proposed change adjusts the configuration bits to apply the vxworks specific flags on top of the cpu ones instead. 2021-12-07 Olivier Hainque <hainque@adacore.com> * config.host (powerpc*-wrs-vxworks7*): Place t-crtstuff ahead of the other files in tmake_files. * config/t-vxworks: Add to CRTSTUFF_T_CFLAGS instead of overriding it.
2021-12-13Leverage sysroot for VxWorksOlivier Hainque3-29/+3
The build of a VxWorks toolchain relies a lot on system headers and VxWorks has a few very specific features that require special processing. For example, different sets of headers for the kernel vs the rtp modes, which the compiler knows about by way of -mrtp on the command line. If we manage to avoid the need for fixincludes on recent versions of VxWorks (>= 7), we still need to handle at least VxWorks 6.9 at this stage. We sort of get away with locating the correct headers at run-time thanks to environment variables and various tests for -mrtp in cpp specs, but getting fixincludes to work for old configurations has always been tricky and getting a toolchain to build with c++/libstdc++ support gets trickier with every move to a more recent release. sysroot_headers_suffix_spec is a pretty powerful device to help address such issues, and this patch introduces changes that let us get advantage of it. The general idea is to leverage the assumption that compilations occur with --sysroot=$VSB_DIR on vx7 or --sysroot=$WIND_BASE/target prior to that. For the toolchains we build, this is achieved with a few configure options like: --with-sysroot --with-build-sysroot=${WIND_BASE}/target --with-specs=%{!sysroot=*:--sysroot=%:getenv(WIND_BASE /target)} This also allows simplifying the libgcc compilation flags control and we take the opportunity to merge t-vxworks7 into t-vxworks as the two files were differing only on the libgcc2 flags part. 2021-12-09 Olivier Hainque <hainque@adacore.com> gcc/ * config/t-vxworks: Clear NATIVE_SYSTEM_HEADER_DIR. * config/vxworks.h (SYSROOT_HEADERS_SUFFIX_SPEC): Define, for VxWorks 7 and earlier.

2021-12-11libgcc: vxcrtstuff.c: make ctor/dtor functions staticRasmus Villemoes1-3/+7
When the translation unit itself creates pointers to the ctors/dtors in a specific section handled by the linker (whether .init_array or .ctors.*), there's no reason for the functions to have external linkage. That ends up polluting the symbol table in the running kernel. This makes vxcrtstuff.c on par with the generic crtstuff.c which also defines e.g. frame_dummy and __do_global_dtors_aux static. libgcc/ * config/vxcrtstuff.c: Make constructor and destructor functions static when possible.
