2019-05-09[PR89221] Continue to default to '--disable-frame-pointer' for x86 GNU systemsThomas Schwinge1-2/+2
The recent trunk r270914 for PR89221 "--enable-frame-pointer does not work as intended" fixed a scripting defect in the x86 '--enable-frame-pointer' handling. This has the side effect that, for example, for '--target=i686-gnu' this is now enabled by default: 'USE_IX86_FRAME_POINTER=1' is added to 'tm_defines'. Given that it's highly unlikely that anyone would now suddenly want '--enable-frame-pointer' as the default for any kind of GNU system, I'm changing the default back for GNU systems, to match that of a 'target_os' of 'linux* | darwin[8912]*'. gcc/ PR target/89221 * configure.ac (--enable-frame-pointer): Disable by default for GNU systems. * configure: Regenerate.

This corrects a long-standing misconfiguration for Darwin. The assembler supports the “.file” and “.loc” directives, but the GCC configury was not detecting this because it was using objdump, which does not exist on most Darwin installations.

2018-11-29[RS6000] inline plt call sequencesAlan Modra1-6/+42
Finally, the point of the previous patches in this series, support for inline PLT calls, keyed off -fno-plt. This emits code using new relocations that tie all insns in the sequence together, so that the linker can edit the sequence back to a direct call should the call target turn out to be local. An example of ELFv2 code to call puts is as follows: .reloc .,R_PPC64_PLTSEQ,puts std 2,24(1) .reloc .,R_PPC64_PLT16_HA,puts addis 12,2,0 .reloc .,R_PPC64_PLT16_LO_DS,puts ld 12,0(12) .reloc .,R_PPC64_PLTSEQ,puts mtctr 12 .reloc .,R_PPC64_PLTCALL,puts bctrl ld 2,24(1) "addis 12,2,puts@plt@ha" and "ld 12,puts@plt@l(12)" are also supported by the assembler. gcc instead uses the explicit R_PPC64_PLT16_HA and R_PPC64_PLT16_LO_DS relocs because when the call is to __tls_get_addr an extra reloc is emitted at every place where one is shown above, to specify the __tls_get_addr arg. The linker expects the extra reloc to come first. .reloc enforces that ordering. The patch also changes code emitted for longcalls if the assembler supports the new marker relocs, so that these too can be edited. One side effect of longcalls using PLT16 relocs is that they can now be resolved lazily by ld.so. I don't support lazy inline PLT calls for ELFv1, because ELFv1 would need barriers to reliably load both the function address and toc pointer from the PLT. ELFv1 -fno-plt uses the longcall sequence instead, which isn't edited by GNU ld. * config.in (HAVE_AS_PLTSEQ): Add. * config/rs6000/predicates.md (indirect_call_operand): New. * config/rs6000/rs6000-protos.h (rs6000_pltseq_template), (rs6000_sibcall_sysv): Declare. * config/rs6000/rs6000.c (init_cumulative_args): Set cookie CALL_LONG for -fno-plt.

2018-10-31Update GCC to autoconf 2.69, automake 1.15.1 (PR bootstrap/82856).Joseph Myers1-934/+997
This patch updates GCC to use autoconf 2.69 and automake 1.15.1. (That's not the latest automake version, but it's the one used by binutils-gdb, with which consistency is desirable, and in any case seems a useful incremental update that should make a future update to 1.16.1 easier.) The changes are generally similar to the binutils-gdb ones, and are copied from there where shared files and directories are involved (there are some further changes to such shared directories, however, which I'd expect to apply to binutils-gdb once this patch is in GCC). Largely, obsolete AC_PREREQ calls are removed, while many AC_LANG_SOURCE calls are added to avoid warnings from aclocal and autoconf. Multilib support is no longer included in core automake, meaning that multilib.am needs copying from automake's contrib directory into the GCC source tree. Autoconf 2.69 has Go support, so local copies of that support are removed. I hope the D support will soon be submitted to upstream autoconf so the local copy of that can be removed in a future update. Changes to how automake generates runtest calls mean quotes are removed from RUNTEST definitions in five lib*/testsuite/Makefile.am files (libatomic, libgomp, libitm, libphobos, libvtv; some others have RUNTEST definitions without quotes, which are still OK); libgo and libphobos also get -Wno-override added to AM_INIT_AUTOMAKE so those overrides of RUNTEST do not generate automake warnings. Note that the regeneration did not include regeneration of fixincludes/config.h.in (attempting such regeneration resulted in all the USED_FOR_TARGET conditionals disappearing; and I don't see anything in the fixincludes/ directory that would result in such conditionals being generated, unlike in the gcc/ directory). Also note that libvtv/testsuite/other-tests/Makefile.in was not regenerated; that directory is not listed as a subdirectory for which Makefile.in gets regenerated by calling "automake" in libvtv/, so I'm not sure how it's meant to be regenerated. While I mostly fixed warnings should running aclocal / automake / autoconf, there were various such warnings from automake in the libgfortran, libgo, libgomp, liboffloadmic, libsanitizer, libphobos directories that I did not fix, preferring to leave those to the relevant subsystem maintainers. Specifically, most of those warnings were of the following form (example from libgfortran): Makefile.am:48: warning: source file 'caf/single.c' is in a subdirectory, Makefile.am:48: but option 'subdir-objects' is disabled automake: warning: possible forward-incompatibility. automake: At least a source file is in a subdirectory, but the 'subdir-objects' automake: automake option hasn't been enabled. For now, the corresponding output automake: object file(s) will be placed in the top-level directory. However, automake: this behaviour will change in future Automake versions: they will automake: unconditionally cause object files to be placed in the same subdirectory automake: of the corresponding sources. automake: You are advised to start using 'subdir-objects' option throughout your automake: project, to avoid future incompatibilities. I think it's best for the relevant maintainers to add subdir-objects and do any other associated Makefile.am changes needed. In some cases the paths in the warnings involved ../; I don't know if that adds any extra complications to the use of subdir-objects. I've tested this with native, cross and Canadian cross builds. The risk of any OS-specific issues should I hope be rather lower than if a libtool upgrade were included (we *should* do such an upgrade at some point, but it's more complicated - it involves identifying all our local libtool changes to see if any aren't included in the upstream version we update to, and reverting an upstream libtool patch that's inappropriate for use in GCC); I think it would be better to get this update into GCC so that people can test in different configurations and we can fix any issues found, rather than to try to get more and more testing done before it goes in. top level: 2018-10-31 Joseph Myers <joseph@codesourcery.com> PR bootstrap/82856 * multilib.am: New file.

2018-09-27rs6000: Delete many HAVE_AS_* (PR87149)Segher Boessenkool1-356/+0
This deletes most HAVE_AS_* that determine if the assembler supports some ISA level (and also HAVE_AS_MFPGPR and HAVE_AS_DFP). These are not useful: we will only generate an instruction that requires some newer ISA if the user specifically asked for it (with -mcpu=, say). If the assembler cannot handle that, it is fine if it gives an error. They also hurt: it increases the number of possible situations that all need handling and all need testing. We do not handle all cases, and obviously do not test all either. This patch removes: HAVE_AS_POPCNTB (power5, 2.02) HAVE_AS_FPRND (power5+, 2.04) HAVE_AS_CMPB (power6, 2.05) HAVE_AS_POPCNTD (power7, 2.06) HAVE_AS_POWER8 (power8, 2.07) HAVE_AS_POWER9 (power9, 3.0) HAVE_AS_DFP (power6, 2.05, server) HAVE_AS_MFPGPR (power6x but not later, not arch) PR target/87149 * config.in (HAVE_AS_CMPB, HAVE_AS_DFP, HAVE_AS_FPRND, HAVE_AS_MFPGPR, HAVE_AS_POPCNTB, HAVE_AS_POPCNTD, HAVE_AS_POWER8, HAVE_AS_POWER9): Delete, always treat as true. * config/powerpcspe/powerpcspe.c (rs6000_option_override_internal): Ditto.

For some targets (in my case VxWorks 5.5), libgcov does not compile due to missing functions and macros such as getpid() and F_OK. Incidentally, gcc/Makefile.in already contains comments such as # Install gcov if it was compiled. but there is no logic in place to actually allow gcov to not be compiled. So add an option for disabling build and install of libgcov and the related host tools. From-SVN: r262180

2018-02-09[LVU] Introduce location viewsAlexandre Oliva1-0/+46
This patch introduces an option to enable the generation of location views along with location lists. The exact format depends on the DWARF version: it can be a separate attribute (DW_AT_GNU_locviews) or (DW_LLE_view_pair) entries in DWARF5+ loclists. Line number tables are also affected. If the assembler is found, at compiler build time, to support .loc views, we use them and assembler-computed view labels, otherwise we output compiler-generated line number programs with conservatively-computed view labels. In either case, we output view information next to line number changes when verbose assembly output is requested. This patch requires an LVU patch that modifies the exported API of final_scan_insn. It also expects the entire SFN patchset to be installed first, although SFN is not a requirement for LVU. for include/ChangeLog * dwarf2.def (DW_AT_GNU_locviews): New. * dwarf2.h (enum dwarf_location_list_entry_type): Add DW_LLE_GNU_view_pair.
