2020-05-27outputs.exp: no lto, linker default output, cdtor temps, empty argsAlexandre Oliva2-48/+119
This patch fixes various issues in the testsuite that came up after the dump/aux output revamp, namely: - many outputs.exp tests used -flto without checking that LTO was supported, getting lots of failures. With this patch, we test for LTO support, and skip -flto tests on platforms that do not support it. - some linkers error out if an output file is not named, and the a.{out,exe} construct that we used throughout outputs.exp to match the default linker output would trigger a bug in tcl globbing. With this patch, we detect the default linker output early. If none is found, we arrange to pass -o a.out explicitly in tests that used to test the default linker output. We now look for the detected default, or for explicitly-specified output. - collect2 will leave <execname>.cdtor.* files behind in -save-temps tests. Ignore them. - The prepending of -Wl, to file names in ldflags et al was done in a way that introduced empty arguments when consecutive blanks appeared in these board configuration knobs. Skip the empty strings between consecutive blanks to avoid this problem. gcc/testsuite/ChangeLog: * lib/gcc-defs.exp: Avoid introducing empty arguments between consecutive blanks in board linking options. * gcc.misc-tests/outputs.exp: Likewise. Document -gsplit-dwarf testing, skip LTO tests if -flto is not supported, detect the default linker output name, cope with the need for an explicit executable output.

2020-05-27libstdc++: Fix view adaptors for mixed-const sentinels and iterators (PR 95322)Jonathan Wakely2-47/+68
The bug report is that transform_view's sentinel<false> cannot be compared to its iterator<true>. The comparison is supposed to use operator==(iterator<Const>, sentinel<Const>) after converting sentinel<false> to sentinel<true>. However, the operator== is a hidden friend so is not a candidate when comparing iterator<true> with sentinel<false>. The required conversion would only happen if we'd found the operator, but we can't find the operator until after the conversion happens. A new LWG issue has been reported, but not yet assigned a number. The solution suggested by Casey Carter is to make the hidden friends of the sentinel types work with iterators of any const-ness, so that no conversions are required. Patrick Palka observed that join_view has a similar problem and a similar fix is used for its sentinel. PR libstdc++/95322 * include/std/ranges (transform_view::_Sentinel): Allow hidden friends to work with _Iterator<true> and _Iterator<false>.

2020-05-27libstdc++: Fix std::reverse_iterator comparisons (PR 94354)Jonathan Wakely2-5/+105
The std::reverse_iterator comparisons have always been implemented only in terms of equality and less than. In C++98 that made no difference for reasonable code, because when the underlying operators are the same type they are required to support all comparisons anyway. But since LWG 280 it's possible to compare reverse_iterator<X> and reverse_iterator<Y>, and comparisons between X and Y might not support the full set of equality and relational operators. This means that it matters whether we implement operator!= as x.base() != y.base() or !(x.base() == y.base()), and the current implementation is non-conforming. This was already fixed in GCC 10.1 for C++20, this change also fixes it for all other -std modes.

2020-05-27i386: Fix V2SF horizontal add/subtract insnsUros Bizjak2-33/+46
PFPNACC insn is incorrectly modelled to perform addition and subtraction of two operands, but in reality it performs horizontal addition and subtraction: Instruction: PFPNACC dest,src Description: dest[31:0] <- dest[31:0] - dest[63:32]; dest[63:32] <- src[31:0] + src[63:32]; Also, it is not possible to directly replace PFACC with HADDPS and PFNACC with HSUBPS, because operands in the second word do not match. PFACC does: dest[31..0] <- dest[31..0] + dest[63..32]; dest[63..32] <- src[31..0] + src [63..32]; while HADDPS does: dest[31..0] <- dest[31..0] + dest[63..32]; dest[63..32] <- dest[127..96] + dest[95..64]; dest[95..64] <- src [31..0] + src [64..32]; dest[127:96] <- src [127..96] + src [95..64]; 2020-05-27 Uroš Bizjak <ubizjak@gmail.com> gcc/ChangeLog: * config/i386/mmx.md (*mmx_haddv2sf3): Remove SSE alternatives.

PR jit/95314 reports a internal error inside verify_gimple, which turned out to be due to reusing the result of gcc_jit_lvalue_get_address in several functions, leading to tree nodes shared between multiple function bodies.

2020-05-27openmp: Fix up omp_declare_variant{s,_alt} htab handlingJakub Jelinek2-0/+38
This patch fixes a GC ICE. During debugging, I've found that during gimplification we can actually call omp_resolve_declare_variant multiple times and it would create a new magic declare_variant_alt FUNCTION_DECL each time, which is undesirable, once we have such a decl, we should just use that. The other problem is that there was no cgraph node removal hook. As the omp_declare_variants htab is used just early during gimplification, we can just clear the whole htab, rather than trying to lookup and remove a particular entry. The other hash table is used later as well and that one uses just DECL_UID as hash, so in that case the patch removes the elt. 2020-05-27 Jakub Jelinek <jakub@redhat.com> PR middle-end/95315 * omp-general.c (omp_declare_variant_remove_hook): New function.

PR jit/95306 reports that attempts to use builtins __builtin_sadd_overflow" and "__builtin_memcpy" via gcc_jit_context_get_builtin_function lead to inscrutable error messages of the form: unimplemented primitive type for builtin: 42 and: unimplemented primitive type for builtin: 38 The root cause is that jit-builtins.c only implements a subset of the types defined via DEF_PRIMITIVE_TYPE in builtin-types.def.

This patch fixes the definition of common_iterator::operator-> when the underlying iterator's operator* returns a non-reference. The first problem is that the class __detail::_Common_iter_proxy is used unqualified. Fixing that revealed another problem: the class's template friend declaration of common_iterator doesn't match up with the definition of common_iterator, because the friend declaration isn't constrained. If we try to make the friend declaration match up by adding constraints, we run into frontend bug PR93467. So we currently can't correctly express this friend relation between __detail::_Common_iter_proxy and common_iterator. As a workaround to this frontend bug, this patch moves the definition of _Common_iter_proxy into the class template of common_iterator so that we could instead express the friend relation via the injected-class-name. (This bug was found when attempting to use views::common to work around the compile failure with the testcase in PR95322.) libstdc++-v3/ChangeLog: PR libstdc++/95322 * include/bits/stl_iterator.h (__detail::_Common_iter_proxy): Remove and instead define it ...

2020-05-26do not skip validation of switch after %<optAlexandre Oliva2-12/+30
After the patch that revamped dump and aux outputs, GCC compilation drivers built without Ada would reject -d* options. Such options would only be validated because of the %{d*} in Ada lang specs, though other languages had it as well. Other languages had %< specs that had to be there before %{d*} %:dumps(), while Ada was missing them. Adding them to Ada brought the same problem to compilers that had Ada enabled. The reason validation failed was that they mishandled %< specs, advancing past the beginning of the next spec, causing it not to be handled. Since %{d*} appeared after an odd %<, it was thus ignored. The logic of validate_switches originally skipped the closing brace that matched the opening brace, but this shouldn't happen for %<. Fixed by letting validate_switches know whether it is handling a braced group or a single atom, and behaving accordingly. gcc/ChangeLog: * gcc.c (validate_switches): Add braced parameter. Adjust all callers. Expected and skip trailing brace only if braced. Return after handling one atom otherwise. (DUMPS_OPTIONS): New. (cpp_debug_options): Define in terms of it. gcc/ada/ChangeLog: * gcc-interface/lang-specs.h (ADA_DUMPS_OPTIONS): Define in terms of DUMPS_OPTIONS. Replace occurrences of %{d*} %:dumps with it.
