2022-10-11Generic configury support for shared libs on VxWorksOlivier Hainque1-1/+30
This change adds the configury bits to activate the build of shared libs on VxWorks ports configured with --enable-shared, for libraries variants where this is generally supported (rtp, code model !large - currently not compatible with -fPIC). Set lt_cv_deplibs_check_method in libtool.m4, so the build of libraries know how to establish dependencies. This is useful in configurations such as aarch64 where proper support of LSE relies on accurate dependency information between libstdc++ and libgcc_s to begin with. Regenerate configure scripts to reflect libtool.m4 change. 2022-10-09 Olivier Hainque <hainque@adacore.com> * libtool.m4 (*vxworks*): When enable_shared, set dynamic_linker and friends for rtp !large.

2021-12-17libgcc, Darwin: Add missing build dependencies.Iain Sandoe1-0/+4
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.

2021-12-13Preserve cpu specific CRTSTUFF_T_CFLAGS on powerpc-vxworks7Olivier Hainque1-1/+2
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 Hainque1-3/+0
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.

2021-12-08libgcc, Darwin: Build a libgcc_s.1 for backwards compatibility.Iain Sandoe1-3/+10
In order to reslve a long-standing issue with inter-operation with libSystem, we have bumped the SO name for libgcc_s. Distributions might wish to install this new version into a structure where exisiting code is already linked with the compiler-local libgcc_s.1 (providing symbols exported by the now-retired libgcc_ext.10.x shims). The replacement libgcc_s.1 forwards the symbols from the new SO. In order to support DYLD_LIBRARY_PATH on systems (where it works) we forward the libSystem unwinder symbols from 10.7+ and a compiler-local version of the libgcc unwinder on earlier. For macOS 10.4 to 10.6 this is 'bug-compatible' with existing uses. For 10.7+ the behaviour will now actually be correct. This should be squashed with the initial libgcc changes for PR80556 in any backport (r12-5418-gd4943ce939d) libgcc/ChangeLog: * config.host (*-*-darwin*): Add logic to build a shared unwinder library for Darwin8-10. * config/i386/t-darwin: Build legacy libgcc_s.1. * config/rs6000/t-darwin: Likewise. * config/t-darwin: Reorganise the EH fragments to place them for inclusion in a shared EH lib. * config/t-slibgcc-darwin: Build a legacy libgcc_s.1 and the supporting pieces (all FAT libs). * config/t-darwin-noeh: Removed. * config/darwin-unwind.ver: New file. * config/rs6000/t-darwin-ehs: New file. * config/t-darwin-ehs: New file.

2021-11-19Darwin: Rework handling for unwinder code in libgcc_s and specs [PR80556].Iain Sandoe1-2/+5
This addresses a long-standing problem where a work-around for an unwinder issue (also a regression) regresses other functionality. The patch replaces several work-arounds with a fix for PR80556 and a work-around for PR88590. * The fix for PR80556 requires a bump to the SO name for libgcc_s, since we need to remove the unwinder symbols from it. This would trigger PR88590 hence the work-around for that. * We weaken the symbols for emulated TLS support so that it is possible for a DSO linked with static-libgcc to interoperate with a DSO linked with libgcc_s. Likewise main exes. * We remove all the gcc-4.2.1 era stubs machinery and workarounds. * libgcc is always now linked ahead of libc, which avoids fails where the libc (libSystem) builtins implementations are not up to date. * The unwinder now always comes from the system - for Darwin9 from /usr/lib/libgcc_s.1.dylib - for Darwin10 from /usr/lib/libSystem.dylib - for Darwin11+ from /usr/lib/system/libunwind.dylib. We still insert a shim on Darwin10 to fix an omitted unwind function, but the underlying unwinder remains the system one. * The work-around for PR88590 has two parts (1) we always link libgcc from its convenience lib on affected system versions (avoiding the need to find the DSO path); (2) we add and export the emutls functions from DSOs - this makes a relatively small (20k) addition to a DSO. These can be backed out when a proper fix for PR88590 is committed. For distributions that wish to install a libgcc_s.1.dylib to satisfy linkage from exes that linked against the stubs can use a reexported libgcc_s.1.1 (since that contains all the symbols that were previously exported via the stubs).

2021-11-05Support TI mode and soft float on PA64John David Anglin1-2/+5
This change implements TI mode on PA64. Various new patterns are added to pa.md. The libgcc build needed modification to build both DI and TI routines. We also need various softfp routines to convert to and from TImode. I added full softfp for the -msoft-float option. At the moment, this doesn't completely eliminate all use of the floating-point co-processor. For this, libgcc needs to be built with -msoft-mult.

This adds ${cpu_type}/t-lse and t-slibgcc-libgcc to the tmake_file list for aarch64-vxworks7* configurations, as the Linux port does. t-lse is needed by all triplets now anyway and the standard setting for slibgcc makes sense as we are working on reintroducing PIC support for RTPs on various targets.

2020-10-30Introduce support for vxworks7r2 on x86 and x86_64Olivier Hainque1-1/+1
This change extends the VxWorks support on intel CPUs to VxWorks7r2 for x86_64 as well as x86, with a "mcmodel=large" additional multilib for the 64bit configuration. The support for fPIC is not functional yet for this model, so we just don't add the corresponding multilib. We extend the range of CPU families handled by TARGET_OS_CPP_BUILTINS, accounting for the fact that archs older than PENTIUM4 are not supported (any more) by VxWorks 7. As we did for powerpc, we leverage VX_CPU_PREFIX to emit different forms of definitions for different families of VxWorks as the system headers's expectations has evolved between Vx 5, 6 and 7. 2020-10-27 Olivier Hainque <hainque@adacore.com> gcc/ * config.gcc: Adjust the ix86/x86_64-wrs-vxworks filters to apply to VxWorks 7 as well. * config/i386/t-vxworks (MULTILIB_OPTIONS, MULTILIB_DIRNAMES): Remove the fPIC multilib and add one for the large code model on x86_64. * config/i386/vxworks.h: Separate sections for TARGET_VXWORKS7, other variants and common bits.

2020-10-21Introduce vxworks7r2 support for ppc and ppc64Douglas Rupp1-0/+17
This change introduces support for the most recent versions of VxWorks on PowerPC targets, for both 32 and 64 bit thanks to a bi-arch setup. The system compilers are essentially configured as Linux toolchains with only a few specificities and we replicate that model here. The most visible specificities are the use of secureplt by default, the pre-definition of some macros that the system headers still rely on (_VX_CPU and _VX_CPU_FAMILY, for example), and of course some variations related to the so VxWorks typical kernel vs RTP mode distinction. In addition to the introduction of config.gcc and libgcc configuration chunks, much inspired by the linux ones, the change - Reworks rs6000/vxworks.h file to feature bits common to the Vx6 and Vx7 port then a separate section for each, where the Vx7 part is very short as we rely on the Linux definitions for most things. - Adjusts the CPU macro predefinitions in CPP_SPEC to resort to "_VX_CPU" instead of "CPU" for Vx7, to better match the more recent system headers expectations, - Adds a cpu definition case for e6500. - Changes to the use SUB3TARGET_OVERRIDE_OPTIONS instead of SUBSUBTARGET_OVERRIDE_OPTIONS for specifics, so we don't override the Linux's version of the latter for vx7. 2020-10-20 Douglas Rupp <rupp@adacore.com> gcc/ * config.gcc (powerpc*-wrs-vxworks7r*): New case. * config/rs6000/vxworks.h: Rework to handle VxWorks7.

2020-06-21aix: Add GCC64 configuration and FAT target libraries.David Edelsohn1-1/+1
This patch adds the ability to configure GCC on AIX to build as a 64 bit application and to build target libraries "FAT" libraries in both 32 bit and 64 bit mode. The patch adds makefile fragment hooks to target libraries that allows them to include target-specific rules. The target specific rules for AIX place both 32 bit and 64 bit objects and shared objects in archives at the top-level, not multilib subdirectories. The multilibs are built in subdirectories, but must be combined during the last parts of the target library build process. Because of the way that GCC bootstrap works, the libraries must be combined during the multiple stages of GCC bootstrap, not solely when installed in the final destination, so the libraries are correct at the end of each target library build stage, not solely an install recipe. gcc/ChangeLog 2020-06-21 David Edelsohn <dje.gcc@gmail.com> * config.gcc: Use t-aix64, biarch64 and default64 for cpu_is_64bit. * config/rs6000/aix72.h (ASM_SPEC): Remove aix64 option.

2020-01-31nios2: Support for GOT-relative DW_EH_PE_datarel encoding.Sandra Loosemore1-1/+2
On nios2-linux-gnu, there has been a long-standing bug in C++ exception handling that sometimes resulted in link errors like ../nios2-linux-gnu/bin/ld: FDE encoding in /tmp/cccfpQ2l.o(.eh_frame) prevents .eh_frame_hdr table being created when building some shared libraries or PIE executables. The root of the problem is that GCC was incorrectly emitting an absolute encoding in EH tables for PIC. This patch changes it to use either DW_EH_PE_indirect (for global) or DW_EH_PE_datarel (for local), and fixes libgcc so it can find the address of the GOT as the base address for DW_EH_PE_datarel. Complicating matters somewhat, GAS was missing support for %gotoff(symbol) relocation syntax. I have just pushed a fix for that, but I've added a configure check to test for presence of the binutils support and fall back to the current absolute encoding (which works most of the time) if it is not available. Once the fix makes it into an official binutils release it might be appropriate to make this error out instead. Since this is a wrong-code bug and affects only nios2 target, I think this is appropriate for Stage 4. I regression-tested on both nios2-linux-gnu and nios2-elf, with and without the binutils support present, before committing this. 2020-01-31 Sandra Loosemore <sandra@codesourcery.com> gcc/ * configure.ac [nios2-*-*]: Check HAVE_AS_NIOS2_GOTOFF_RELOCATION. * config.in: Regenerated. * configure: Regenerated. * config/nios2/nios2.h (ASM_PREFERRED_EH_DATA_FORMAT): Fix handling for PIC when HAVE_AS_NIOS2_GOTOFF_RELOCATION.

2019-11-12 Corentin Gay <gay@adacore.com> Jerome Lambourg <lambourg@adacore.com> Olivier Hainque <hainque@adacore.com> libgcc/ * config/t-gthr-vxworks: New file, add all the gthr-vxworks sources to LIB2ADDEH. * config/t-vxworks: Remove adjustments to LIB2ADDEH. * config/t-vxworks7: Likewise. * config.host: Append a block at the end of the file to add the t-gthr files to the tmake_file list for VxWorks after everything else. * config/vxlib.c: Rename as gthr-vxworks.c. * config/vxlib-tls.c: Rename as gthr-vxworks-tls.c. * config/gthr-vxworks.h: Simplify a few comments. Expose a TAS API and a basic error checking API, both internal. Simplify the __gthread_once_t type definition and initializers. Add sections for condition variables support and for the C++0x thread support, conditioned against Vx653 for the latter. * config/gthr-vxworks.c (__gthread_once): Simplify comments and implementation, leveraging the TAS internal API. * config/gthr-vxworks-tls.c: Introduce an internal TLS data access API, leveraging the general availability of TLS services in VxWorks7 post SR6xxx. (__gthread_setspecific, __gthread_setspecific): Use it. (tls_delete_hook): Likewise, and simplify the enter/leave dtor logic. * config/gthr-vxworks-cond.c: New file. GTHREAD_COND variable support based on VxWorks primitives. * config/gthr-vxworks-thread.c: New file. GTHREAD_CXX0X support based on VxWorks primitives.

2019-11-06 Jerome Lambourg <lambourg@adacore.com> Olivier Hainque <hainque@adacore.com> libgcc/ * config/vxcrtstuff.c: New file. * config/t-vxcrtstuff: New Makefile fragment. * config.host: Append t-vxcrtstuff to the tmake_file list on all VxWorks ports using dwarf for table based EH. gcc/ * config/vx-common.h (USE_TM_CLONE_REGISTRY): Remove definition, pointless with a VxWorks specific version of crtstuff. (DWARF2_UNWIND_INFO): Conditionalize on !ARM_UNWIND_INFO. * config/vxworks.h (VX_CRTBEGIN_SPEC, VX_CRTEND_SPEC): New local macros, controlling the addition of vxworks specific crtstuff objects depending on the EH mechanism and kind of module being linked. (VXWORKS_STARTFILE_SPEC, VXWORKS_ENDFILE_SPEC): Use them. Co-Authored-By: Olivier Hainque <hainque@adacore.com> From-SVN: r278248
