2020-09-08MSP430: Fix detection of assembler support for .mspabi_attributeJozef Lawrynowicz1-1/+1
The assembly code ".mspabi_attribute 4,1" uses the object attribute mechanism to indicate that the 430 ISA is in use. However, the default ISA is 430X, so GAS fails to assemble this since the ISA wasn't also set to 430 on the command line. gcc/ChangeLog: * config/msp430/msp430.c (msp430_file_end): Fix jumbled HAVE_AS_MSPABI_ATTRIBUTE and HAVE_AS_GNU_ATTRIBUTE checks. * configure: Regenerate. * configure.ac: Use ".mspabi_attribute 4,2" to check for assembler support for this object attribute directive.
2020-08-03Removal of HSA offloading from gcc and libgompMartin Jambor1-32/+22
This patch removes the generation of HSAIL from the compiler, the HSA offloading plugin from libgomp and the associated testsuite tests and infrastructure bits from the respective testsuites. Apart from removal of the obvious files, I removed bits that I found by searching for HSA related terms and by re-tracing my steps and looking at the patches that introduced HSA in the first place. I did not remove everything these patches brought in, for example: - the mechanism to pass offload-target specific info from the application to the offloading plugin - but the same mechanism is also used to communicate number of teams and the thread limit to all offload targets. - run_func hook in gomp_device_descr stays too, although now it is not used. If some future offload target would like the ability to refuse to offload some functions, it can use it. It is easy to remove as a follow-up if it is considered clutter, though. - configure options --with-hsa-runtime=PATH, -with-hsa-runtime-include=PATH and --with-hsa-runtime-lib=PATH rmeain because GCN uses them too. - Surprisingly, GOMP_TARGET_ARG_HSA_KERNEL_ATTRIBUTES (a constant from gomp-constants.h) appears in the source of the amdgcn libgomp plugin, although I tend to think that code path is not ever used and this patch certainly removes it from the compiler. Nevertheless, it seems it has potential value beyond HSAIL and so I've kept it, it can of course always be easily removed in the future of GCN folk abandon it too. - I assume constants OFFLOAD_TARGET_TYPE_HSA and GOMP_DEVICE_HSA need to stay indefinitely too just so that no future offload target picks that number. - I have kept dg-require-effective-target offload_device_nonshared_as requirement of thests which have it. It is quite probable I missed some small HSA artifacts but those should be easy to remove later as we find them. include/ChangeLog: 2020-07-24 Martin Jambor <mjambor@suse.cz> * gomp-constants.h (GOMP_VERSION_HSA): Remove. gcc/ChangeLog: 2020-07-24 Martin Jambor <mjambor@suse.cz> * hsa-brig-format.h: Moved to brig/brigfrontend. * hsa-brig.c: Removed. * hsa-builtins.def: Likewise. * hsa-common.c: Likewise. * hsa-common.h: Likewise. * hsa-dump.c: Likewise. * hsa-gen.c: Likewise. * hsa-regalloc.c: Likewise. * ipa-hsa.c: Likewise. * omp-grid.c: Likewise. * omp-grid.h: Likewise. * Makefile.in (BUILTINS_DEF): Remove hsa-builtins.def.

Previously I had AX_CXX_COMPILE_STDCXX in the gcc directory configure, which added -std=c++11 to CXX if needed, but then CXX is overridden from the toplevel directory, so it didn't have the desired effect. Fixed by moving the check to the toplevel.

2020-05-05build: Fix 32-bit TLS detection with 64-bit-default gas on Solaris/x86Rainer Orth1-0/+5
I've recently tested i386-pc-solaris2.11 bootstrap on Solaris 11/x86 with only the bundled tools (using /usr/gnu/bin/as from binutils 2.30 in this case). It failed compiling libgo/runtime/proc.c, creating invalid assembly: proc.s: Assembler messages: proc.s:2092: Error: junk at end of line, first unrecognized character is `*' .globl __emutls_v.*runtime.g and several more errors. This is completely unexpected since Solaris does support TLS. It turned out that 32-bit TLS detection in gcc/configure had failed: configure:25145: checking assembler for thread-local storage support configure:25158: /usr/gnu/bin/as --fatal-warnings -o conftest.o conftest.s >&5 conftest.s: Assembler messages: conftest.s:6: Error: relocated field and relocation type differ in signedness conftest.s:7: Error: @TLSLDM reloc is not supported with 64-bit output format conftest.s:7: Error: junk `@tlsldm' after expression which isn't unexpected given that the bundled gas has been configured for x86_64-pc-solaris2.11, i.e. 64-bit-default. This is easily fixed by explicitly passing --32 for the 32-bit case, matching what is done for the 64-bit test. Tested on i386-pc-solaris2.11 with 32-bit-default and 64-bit-default gas as well as with /usr/bin/as, always correctly detecting TLS support. * configure.ac <i[34567]86-*-*>: Add --32 to tls_as_opt on Solaris. * configure: Regenerate.

2020-04-27Fix warning URLs for Fortran and analyzer [PR 92830]David Malcolm1-1/+1
PR 92830 reports that we always use "gcc/Warning-Options.html" when we emit escaped documentation URLs when printing "[-Wname-of-option]" for a warning. This page is wrong for most Fortran warnings, and for analyzer warnings. I considered various schemes involving adding extra tags to the .opt format to capture where options are documented, but for now this patch fixes the issue by introducing some special-casing logic. It only fixes the URLs for warning options, not for other command-line options, but those are the only options for which get_option_url is currently called. gcc/ChangeLog: PR 92830 * configure.ac (DOCUMENTATION_ROOT_URL): Drop trailing "gcc/" from default value, so that it can by supplied by get_option_html_page. * configure: Regenerate. * opts.c: Include "selftest.h".

2020-01-31nios2: Support for GOT-relative DW_EH_PE_datarel encoding.Sandra Loosemore1-0/+37
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.

2019-11-20Switch gcc ftp URL's to httpsJanne Blomqvist1-1/+1
The FTP protocol is getting long in the tooth, and we should emphasize HTTPS where that is available. This patch changes various gcc.gnu.org URL's to instead use HTTPS. For instance, kernel.org shut down FTP access in 2017, with the explanation: - The protocol is inefficient and requires adding awkward kludges to firewalls and load-balancing daemons - FTP servers have no support for caching or accelerators, which has significant performance impacts - Most software implementations have stagnated and see infrequent updates ChangeLog: 2019-11-20 Janne Blomqvist <jb@gcc.gnu.org> * configure.ac: Use https for gcc.gnu.org. * configure: Regenerated. gcc/ChangeLog: 2019-11-20 Janne Blomqvist <jb@gcc.gnu.org> * configure.ac: Use https for gcc.gnu.org. * configure: Regenerated. * doc/install.texi: Use https for gcc.gnu.org. * doc/sourcebuild.texi: Likewise. gcc/testsuite/ChangeLog: 2019-11-20 Janne Blomqvist <jb@gcc.gnu.org> * README: Use https for gcc.gnu.org. libstdc++-v3/ChangeLog: 2019-11-20 Janne Blomqvist <jb@gcc.gnu.org> * doc/html/api.html: Use https for gcc.gnu.org. * doc/xml/api.xml: Likewise. maintainer-scripts/ChangeLog: 2019-11-20 Janne Blomqvist <jb@gcc.gnu.org> * gcc_release: Use https for gcc.gnu.org.

2019-11-11[build] Properly track GCC language configure fragmentsThomas Schwinge1-3/+7
The 'gcc/configure' script sources all 'gcc/*/config-lang.in' files, but fails to emit such dependency information into the build machinery. That means, currently, when something gets changed in a 'gcc/*/config-lang.in' file, this is not noticed, and doesn't propagate through the build machinery. Handling of configure fragments is modelled in the same way as it already exists for Makefile fragments. gcc/ * Makefile.in (LANG_CONFIGUREFRAGS): Define.

2019-11-04pass --enable-obsolete down to gcc/configure for auto-build.hAlexandre Oliva1-3/+10
Configuring GCC for obsolete targets works as long as build = host. When it isn't, --enable-obsolete is not passed down to the additional build configure started by gcc/configure, used to generate auto-build.h. The build configure fails and we end up without a auto-build.h, but the host configure proceeds, so we only get a fatal failure much later, when make realizes auto-build.h is not there and there's no rule to create it. This patch gets the host configure to fail when the build configure does, leaving the temporary build configure dir behind for investigation. It also arranges for --eanble-obsolete to be passed down to the build configure. Alas, the latter triggered a warning in the build configure because --enable-obsolete is not a recognized configure option. That's not reported in the host configure because of the --disable-option-checking passed by the top-level configure, so I arranged for that to be passed down to the build configure as well. Finally, since my initial suspicion when investigating this failure was that auto-build.h had been removed after configuration and there was no rule to rebuild it, I'm adding rules to gcc/Makefile to get it created or updated as needed. Since it is configure that creates it, as run by e.g. config.status --recheck, and config.status is created after auto-build.h, I've made config.status depend on auto-build.h, and added a dummy rule to create auto-build.h. This would normally not be enough to create a header when needed, but since Makefile depends on config.status, and make first updates Makefile, it ends up working, as long as nothing else that Makefile depends on requires auto-build.h but not config.status. The config.status dependency and the auto-build.h rule are only enabled in the cases in which auto-build.h is actually used, namely when build != host. for gcc/ChangeLog * configure.ac: Pass --enable-obsolete=* and --enable-option-checking=* down to build configure, and fail if it fails.

Apart from doing the same twice this is actually harmful in sufficiently parallelized `make' invocation, as the removal of old files performed within the `install-gnatlib' recipe in the former case actually races with the installation of new files done in the latter case, causing the recipe to fail and abort, however non-fatally, having not completed the installation of all the built files needed for the newly-built compiler to work correctly. This can be observed with a native `x86_64-linux-gnu' bootstrap: make[4]: Entering directory '.../gcc/ada' rm -rf .../lib/gcc/x86_64-linux-gnu/10.0.0/adalib rm: cannot remove '.../lib/gcc/x86_64-linux-gnu/10.0.0/adalib': Directory not empty make[4]: *** [gcc-interface/Makefile:512: install-gnatlib] Error 1 make[4]: Leaving directory '.../gcc/ada' make[3]: *** [.../gcc/ada/gcc-interface/Make-lang.in:853: install-gnatlib] Error 2 make[2]: [.../gcc/ada/gcc-interface/Make-lang.in:829: ada.install-common] Error 2 (ignored) which then causes missing files to be reported when an attempt is made to use the newly-installed non-functional compiler to build a `riscv-linux-gnu' cross-compiler: (cd ada/bldtools/sinfo; gnatmake -q xsinfo ; ./xsinfo sinfo.h ) error: "ada.ali" not found, "ada.ads" must be compiled error: "s-memory.ali" not found, "s-memory.adb" must be compiled gnatmake: *** bind failed. /bin/sh: ./xsinfo: No such file or directory make[2]: *** [.../gcc/ada/Make-generated.in:45: ada/sinfo.h] Error 127 make[2]: Leaving directory '.../gcc' make[1]: *** [Makefile:4369: all-gcc] Error 2 make[1]: Leaving directory '...' make: *** [Makefile:965: all] Error 2 Depending on timing `.../lib/gcc/x86_64-linux-gnu/10.0.0/adainclude' may cause an installation failure instead and the resulting compiler may be non-functional in a different way. Only invoke `install-gnatlib' from within gcc/ then if a legacy build process is being used with libada disabled and gnatlib built manually with `make -C gcc gnatlib'. gcc/ * Makefile.in (gnat_install_lib): New variable. * configure.ac: Substitute it. * configure: Regenerate. gcc/ada/ * gcc-interface/Make-lang.in (ada.install-common): Split into...
