2020-05-28aarch64: Fix missed shrink-wrapping opportunityRichard Sandiford3-0/+44
wb_candidate1 and wb_candidate2 exist for two overlapping cases: when we use an STR or STP with writeback to allocate the frame, and when we set up a frame chain record (either using writeback allocation or not). However, aarch64_layout_frame was leaving these fields with legitimate register numbers even if we decided to do neither of those things. This prevented those registers from being shrink-wrapped, even though we were otherwise treating them as normal saves and restores. The case this patch handles isn't the common case, so it might not be worth going out of our way to optimise it. But I think the patch actually makes the output of aarch64_layout_frame more consistent. 2020-05-28 Richard Sandiford <richard.sandiford@arm.com> gcc/ * config/aarch64/aarch64.h (aarch64_frame): Add a comment above wb_candidate1 and wb_candidate2. * config/aarch64/aarch64.c (aarch64_layout_frame): Invalidate wb_candidate1 and wb_candidate2 if we decided not to use them. gcc/testsuite/ * gcc.target/aarch64/shrink_wrap_1.c: New test.
2020-05-28aarch64: Fix segfault in aarch64_expand_epilogue [PR95361]Richard Sandiford2-1/+16
The stack frame for the function in the testcase consisted of two SVE save slots. Both saves had been shrink-wrapped, but for different blocks, meaning that the stack allocation and deallocation were separate from the saves themselves. Before emitting the deallocation, we tried to attach a REG_CFA_DEF_CFA note to the preceding instruction, to redefine the CFA in terms of the stack pointer. But in this case there was no preceding instruction. This in practice only happens for SVE because: (a) We don't try to shrink-wrap wb_candidate* registers even when we've decided to treat them as normal saves and restores. I have a fix for that. (b) Even with (a) fixed, we're (almost?) guaranteed to emit a stack tie for frames that are 64k or larger, so we end up hanging the REG_CFA_DEF_CFA note on that instead. We should only need to redefine the CFA if it was previously defined in terms of the frame pointer. In other cases the CFA should already be defined in terms of the stack pointer, so redefining it is unnecessary but usually harmless. 2020-05-28 Richard Sandiford <richard.sandiford@arm.com> gcc/ PR testsuite/95361 * config/aarch64/aarch64.c (aarch64_expand_epilogue): Assert that we have at least some CFI operations when using a frame pointer.

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.

2020-05-27i386: 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.

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. (omp_resolve_declare_variant): Always return base if it is already declare_variant_alt magic decl itself.

2020-05-26jit: fix missing types for builtins [PR 95306]David Malcolm8-11/+279
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: - implements enough types to enable the above two builtins to be referenced - documents gcc_jit_context_get_builtin_function, and notes the limitation that not all types are supported (supporting some of them would take a lot of extra work) - improves the error message for the unsupported cases - adds a testcase for __builtin_memcpy. This required jit_langhook_global_bindings_p to be implemented (otherwise the assertion there failed deep inside "expand" on the builtin) - adds test coverage for the above gcc/jit/ChangeLog: PR jit/95306 * docs/topics/functions.rst (gcc_jit_context_get_builtin_function): Document. * docs/_build/texinfo/libgccjit.texi: Regenerate. * dummy-frontend.c (jit_langhook_global_bindings_p): Remove gcc_unreachable. * jit-builtins.c (type_names): New array.
