versions. This brings in the following commits: commit c73cc6fe6207b2863afa31a3be8ad87b70d3df0a Author: Jakub Jelinek <jakub@redhat.com> Date: Tue Dec 5 23:32:19 2023 +0100 libiberty: Fix build with GCC < 7 Tobias reported on IRC that the linker fails to build with GCC 4.8.5. In configure I've tried to use everything actually used in the sha1.c x86 hw implementation, but unfortunately I forgot about implicit function declarations. GCC before 7 did have <cpuid.h> header and bit_SHA define and __get_cpuid function defined inline, but it didn't define __get_cpuid_count, which compiled fine (and the configure test is intentionally compile time only) due to implicit function declaration, but then failed to link when linking the linker, because __get_cpuid_count wasn't defined anywhere. The following patch fixes that by using what autoconf uses in AC_CHECK_DECL to make sure the functions are declared. commit 691858d279335eeeeed3afafdf872b1c5f8f4201 Author: Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE> Date: Tue Dec 5 11:04:06 2023 +0100 libiberty: Fix pex_unix_wait return type The recent warning patches broke Solaris bootstrap: /vol/gcc/src/hg/master/local/libiberty/pex-unix.c:326:3: error: initialization of 'pid_t (*)(struct pex_obj *, pid_t, int *, struct pex_time *, int, const char **, int *)' {aka 'long int (*)(struct pex_obj *, long int, int *, struct pex_time *, int, const char **, int *)'} from incompatible pointer type 'int (*)(struct pex_obj *, pid_t, int *, struct pex_time *, int, const char **, int *)' {aka 'int (*)(struct pex_obj *, long int, int *, struct pex_time *, int, const char **, int *)'} [-Wincompatible-pointer-types] 326 | pex_unix_wait, | ^~~~~~~~~~~~~ /vol/gcc/src/hg/master/local/libiberty/pex-unix.c:326:3: note: (near initialization for 'funcs.wait') While pex_funcs.wait expects a function returning pid_t, pex_unix_wait currently returns int. However, on Solaris pid_t is long for 32-bit, but int for 64-bit. This patches fixes this by having pex_unix_wait return pid_t as expected, and like every other variant already does. Bootstrapped without regressions on i386-pc-solaris2.11, sparc-sun-solaris2.11, x86_64-pc-linux-gnu, and x86_64-apple-darwin23.1.0. commit c3f281a0c1ca50e4df5049923aa2f5d1c3c39ff6 Author: Jason Merrill <jason@redhat.com> Date: Mon Sep 25 10:15:02 2023 +0100 c++: mangle function template constraints Per https://github.com/itanium-cxx-abi/cxx-abi/issues/24 and https://github.com/itanium-cxx-abi/cxx-abi/pull/166 We need to mangle constraints to be able to distinguish between function templates that only differ in constraints. From the latter link, we want to use the template parameter mangling previously specified for lambdas to also make explicit the form of a template parameter where the argument is not a "natural" fit for it, such as when the parameter is constrained or deduced. I'm concerned about how the latter link changes the mangling for some C++98 and C++11 patterns, so I've limited template_parm_natural_p to avoid two cases found by running the testsuite with -Wabi forced on: template <class T, T V> T f() { return V; } int main() { return f<int,42>(); } template <int i> int max() { return i; } template <int i, int j, int... rest> int max() { int sub = max<j, rest...>(); return i > sub ? i : sub; } int main() { return max<1,2,3>(); } A third C++11 pattern is changed by this patch: template <template <typename...> class TT, typename... Ts> TT<Ts...> f(); template <typename> struct A { }; int main() { f<A,int>(); } I aim to resolve these with the ABI committee before GCC 14.1. We also need to resolve https://github.com/itanium-cxx-abi/cxx-abi/issues/38 (mangling references to dependent template-ids where the name is fully resolved) as references to concepts in std:: will consistently run into this area. This is why mangle-concepts1.C only refers to concepts in the global namespace so far. The library changes are to avoid trying to mangle builtins, which fails. Demangler support and test coverage is not complete yet. commit f2c52c0dfde581461959b0e2b423ad106aadf179 Author: Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE> Date: Thu Nov 30 10:06:23 2023 +0100 libiberty: Disable hwcaps for sha1.o This patch commit bf4f40cc3195eb7b900bf5535cdba1ee51fdbb8e Author: Jakub Jelinek <jakub@redhat.com> Date: Tue Nov 28 13:14:05 2023 +0100 libiberty: Use x86 HW optimized sha1 broke Solaris/x86 bootstrap with the native as: libtool: compile: /var/gcc/regression/master/11.4-gcc/build/./gcc/gccgo -B/var/gcc/regression/master/11.4-gcc/build/./gcc/ -B/vol/gcc/i386-pc-solaris2.11/bin/ -B/vol/gcc/i386-pc-solaris2.11/lib/ -isystem /vol/gcc/i386-pc-solaris2.11/include -isystem /vol/gcc/i386-pc-solaris2.11/sys-include -fchecking=1 -minline-all-stringops -O2 -g -I . -c -fgo-pkgpath=internal/goarch /vol/gcc/src/hg/master/local/libgo/go/internal/goarch/goarch.go zgoarch.go ld.so.1: go1: fatal: /var/gcc/regression/master/11.4-gcc/build/gcc/go1: hardware capability (CA_SUNW_HW_2) unsupported: 0x4000000 [ SHA1 ] gccgo: fatal error: Killed signal terminated program go1 As is already done in a couple of other similar cases, this patches disables hwcaps support for libiberty. Initially, this didn't work because config/hwcaps.m4 uses target_os, but didn't ensure it is defined. Tested on i386-pc-solaris2.11 with as and gas. commit bf4f40cc3195eb7b900bf5535cdba1ee51fdbb8e Author: Jakub Jelinek <jakub@redhat.com> Date: Tue Nov 28 13:14:05 2023 +0100 libiberty: Use x86 HW optimized sha1 Nick has approved this patch (+ small ld change to use it for --build-id=), so I'm commiting it to GCC as master as well. If anyone from ARM would be willing to implement it similarly with vsha1{cq,mq,pq,h,su0q,su1q}_u32 intrinsics, it could be a useful linker speedup on those hosts as well, the intent in sha1.c was that sha1_hw_process_bytes, sha1_hw_process_block functions would be defined whenever defined (HAVE_X86_SHA1_HW_SUPPORT) || defined (HAVE_WHATEVERELSE_SHA1_HW_SUPPORT) but the body of sha1_hw_process_block and sha1_choose_process_bytes would then have #elif defined (HAVE_WHATEVERELSE_SHA1_HW_SUPPORT) for the other arch support, similarly for any target attributes on sha1_hw_process_block if needed. commit 01bc30b222a9d2ff0269325d9e367f8f1fcef942 Author: Mark Wielaard <mjw@redhat.com> Date: Wed Nov 15 20:27:08 2023 +0100 Regenerate libiberty/aclocal.m4 with aclocal 1.15.1 There is a new buildbot check that all autotool files are generated with the correct versions (automake 1.15.1 and autoconf 2.69). https://builder.sourceware.org/buildbot/#/builders/gcc-autoregen Correct one file that was generated with the wrong version. commit 879cf9ff45d94065d89e24b71c6b27c7076ac518 Author: Brendan Shanks <bshanks@codeweavers.com> Date: Thu Nov 9 21:01:07 2023 -0700 [PATCH v3] libiberty: Use posix_spawn in pex-unix when available. Hi, This patch implements pex_unix_exec_child using posix_spawn when available. This should especially benefit recent macOS (where vfork just calls fork), but should have equivalent or faster performance on all platforms. In addition, the implementation is substantially simpler than the vfork+exec code path. Tested on x86_64-linux. v2: Fix error handling (previously the function would be run twice in case of error), and don't use a macro that changes control flow. v3: Match file style for error-handling blocks, don't close in/out/errdes on error, and check close() for errors. commit 810bcc00156cefce7ad40fc9d8de6e43c3a04450 Author: Jason Merrill <jason@redhat.com> Date: Thu Aug 17 11:36:23 2023 -0400 c++: constrained hidden friends [PR109751] r13-4035 avoided a problem with overloading of constrained hidden friends by checking satisfaction, but checking satisfaction early is inconsistent with the usual late checking and can lead to hard errors, so let's not do that after all. We were wrongly treating the different instantiations of the same friend template as the same function because maybe_substitute_reqs_for was failing to actually substitute in the case of a non-template friend. But we don't actually need to do the substitution anyway, because [temp.friend] says that such a friend can't be the same as any other declaration. After fixing that, instead of a redefinition error we got an ambiguous overload error, fixed by allowing constrained hidden friends to coexist until overload resolution, at which point they probably won't be in the same ADL overload set anyway. And we avoid mangling collisions by following the proposed mangling for these friends as a member function with an extra 'F' before the name. I demangle this by just adding [friend] to the name of the function because it's not feasible to reconstruct the actual scope of the function since the mangling ABI doesn't distinguish between class and namespace scopes.

Mark did the code formatting to GNU style and integration into the gcc/libiberty build system and testsuite. include/ChangeLog: 2016-11-03 David Tolnay <dtolnay@gmail.com> Mark Wielaard <mark@klomp.org> * demangle.h (DMGL_RUST): New macro.

2015-11-28PR other/61321 - demangler crash on casts in template parametersPedro Alves1-0/+4
The fix for bug 59195: [C++ demangler handles conversion operator incorrectly] https://gcc.gnu.org/bugzilla/show_bug.cgi?id=59195 unfortunately makes the demangler crash due to infinite recursion, in case of casts in template parameters. For example, with: template<int> struct A {}; template <typename Y> void function_temp(A<sizeof ((Y)(999))>) {} template void function_temp<int>(A<sizeof (int)>); The 'function_temp<int>' instantiation above mangles to: _Z13function_tempIiEv1AIXszcvT_Li999EEE The demangler parses this as: typed name template name 'function_temp' template argument list builtin type int function type builtin type void argument list template (*) name 'A' template argument list unary operator operator sizeof unary operator cast template parameter 0 (**) literal builtin type int name '999' And after the fix for 59195, due to: static void d_print_cast (struct d_print_info *dpi, int options, const struct demangle_component *dc) { ... /* For a cast operator, we need the template parameters from the enclosing template in scope for processing the type. */ if (dpi->current_template != NULL) { dpt.next = dpi->templates; dpi->templates = &dpt; dpt.template_decl = dpi->current_template; } when printing the template argument list of A (what should be "<sizeof (int)>"), the template parameter 0 (that is, "T_", the '**' above) now refers to the first parameter of the the template argument list of the 'A' template (the '*' above), exactly what we were already trying to print. This leads to infinite recursion, and stack exaustion. The template parameter 0 should actually refer to the first parameter of the 'function_temp' template. Where it reads "for the cast operator" in the comment in d_print_cast (above), it's really talking about a conversion operator, like: struct A { template <typename U> explicit operator U(); }; We don't want to inject the template parameters from the enclosing template in scope when processing a cast _expression_, only when handling a conversion operator. The problem is that DEMANGLE_COMPONENT_CAST is currently ambiguous, and means _both_ 'conversion operator' and 'cast expression'. Fix this by adding a new DEMANGLE_COMPONENT_CONVERSION component type, which does what DEMANGLE_COMPONENT_CAST does today, and making DEMANGLE_COMPONENT_CAST just simply print its component subtree. I think we could instead reuse DEMANGLE_COMPONENT_CAST and in d_print_comp_inner still do: @@ -5001,9 +5013,9 @@ d_print_comp_inner (struct d_print_info *dpi, int options, d_print_comp (dpi, options, dc->u.s_extended_operator.name); return; case DEMANGLE_COMPONENT_CAST: d_append_string (dpi, "operator "); - d_print_cast (dpi, options, dc); + d_print_conversion (dpi, options, dc); return; leaving the unary cast case below calling d_print_cast, but seems to me that spliting the component types makes it easier to reason about the code. g++'s testsuite actually generates three symbols that crash the demangler in the same way. I've added those as tests in the demangler testsuite as well. And then this fixes PR other/61233 too, which happens to be a demangler crash originally reported to GDB, at: https://sourceware.org/bugzilla/show_bug.cgi?id=16957 Bootstrapped and regtested on x86_64 Fedora 20. Also ran this through GDB's testsuite. GDB will require a small update to use DEMANGLE_COMPONENT_CONVERSION in one place it's using DEMANGLE_COMPONENT_CAST in its sources. libiberty/ 2015-11-27 Pedro Alves <palves@redhat.com> PR other/61321 PR other/61233 * demangle.h (enum demangle_component_type) <DEMANGLE_COMPONENT_CONVERSION>: New value. * cp-demangle.c (d_demangle_callback, d_make_comp): Handle DEMANGLE_COMPONENT_CONVERSION.
