The existing precondition guarded against exception Dereference_Error, but not against Constraint_Error. The RM rule B.3.1(36/3) only mentions Constraint_Error for the Value function which returns char_array, but the one which returns String has the same restriction, because it is equivalent to calling the variant which returns char_array and then converted. gcc/ada/ * libgnat/i-cstrin.ads (Value): Extend preconditions; adapt comment for the package.

When first added explicitly in 3ddffba9 ("i386.md (sse4_1_round<mode>2): Add avx512f alternative"), "*" should not have been used for the pre-existing alternative. The attribute was plain missing. Subsequent changes adding more alternatives then generously extended the bogus pattern.

In the rdrand and rdseed cases "prefix_0f" is meant instead. For mmx_floatv2siv2sf2 1 is correct only for the first alternative. For the integer min/max cases 1 uniformly applies to legacy and VEX encodings (the UB and SW variants are dealt with separately anyway). Same for {,V}MOVNTDQA. Unlike {,V}PEXTRW, which has two encoding forms, {,V}PINSRW only has a single form in 0f space. (In *vec_extract<mode> note that the dropped part if the condition also referenced non-existing alternative 2.) Of the integer compare insns, only the 64-bit element forms are encoded in 0f38 space. gcc/ * config/i386/i386.md (@rdrand<mode>): Add "prefix_0f". Drop "prefix_extra".

Record common properties in other attributes' default calculations: There's always a 1-byte immediate, and they're always encoded in a VEX3- like manner (note that "prefix_extra" already evaluates to 1 in this case). The drop now (or already previously) redundant explicit attributes, adding "mode" ones where they were missing. Furthermore use "sse4arg" consistently for all VPCOM* insns; so far signed comparisons did use it, while unsigned ones used "ssecmp". Note that while they have (not counting the explicit or implicit immediate operand) they really only have 3 operands, the operator is also counted in those patterns. That's relevant for establishing the "memory" attribute's value, and at the same time benign when there are only register operands. Note that despite also having 4 operands, multiply-add insns aren't affected by this change, as they use "ssemuladd" for "type". gcc/ * config/i386/i386.md (length_immediate): Handle "sse4arg".

Drop SSE5 leftovers from both its comment and its default calculation. A value of 2 simply cannot occur anymore. Instead extend the comment to mention the use of the attribute in "length_vex", clarifying why "prefix_extra" can actually be meaningful on VEX-encoded insns despite those not having any real prefixes except possibly segment overrides. gcc/ * config/i386/i386.md (prefix_extra): Correct comment.

As detailed in LLVM Issue #57624 (https://github.com/llvm/llvm-project/issues/57624), a patch to sanitizer_internal_defs.h broke SPARC stacktraces in the sanitizers. The issue has now been fixed upstream (https://reviews.llvm.org/D156504) and I'd like to cherry-pick that patch. Bootstrapped without regressions on sparc-sun-solaris2.11. 2023-07-27 Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE> libsanitizer: * sanitizer_common/sanitizer_stacktrace_sparc.cpp, sanitizer_common/sanitizer_unwind_linux_libcdep.cpp: Cherry-pick llvm-project revision 679c076ae446af81eba81ce9b94203a273d4b88a.

If loop is ifconverted and later versioning by vectorizer, vectorizer will reuse the scalar loop produced by ifconvert. Curiously enough it does not seem to do so for versions produced by loop distribution while for loop distribution this matters (since since both ldist versions survive to final code) while after ifcvt it does not (since we remove non-vectorized path). This patch fixes associated profile update. Here it is necessary to scale both arms of the conditional according to runtime checks inserted. We got partly right the loop body, but not the preheader block and block after exit. The first is particularly bad since it changes loop iterations estimates. So we now turn 4 original loops: loop 1: iterations by profile: 473.497707 (reliable) entry count:84821 (precise, freq 0.9979) loop 2: iterations by profile: 100.000000 (reliable) entry count:39848881

My apologies (again), I managed to mess up the 64-bit version of the test case for PR 110792. Unlike the 32-bit version, the 64-bit case contains exactly the same load instructions, just in a different order making the correct and incorrect behaviours impossible to distinguish with a scan-assembler-not. Somewhere between checking that this test failed in a clean tree without the patch, and getting the escaping correct, I'd failed to notice that this also FAILs in the patched tree. Doh! Instead of removing the test completely, I've left it as a compilation test. The original fix is tested by the 32-bit test case. Committed to mainline as obvious.

This prevents useless loop distribiton produced in hmmer. With FDO we now correctly work out that the loop created for last iteraiton is not going to iterate however loop distribution still produces a verioned loop that has no chance to survive loop vectorizer since we only keep distributed loops when loop vectorization suceeds and it requires number of (header) iterations to exceed the vectorization factor. gcc/ChangeLog: * tree-loop-distribution.cc (loop_distribution::execute): Disable distribution for loops with estimated iterations 0.

Epilogue peeling expects the scalar loop to have same number of executions as the vector loop which is true at the beggining of vectorization. However if the epilogues are vectorized, this is no longer the case. In this situation the loop preheader is replaced by new guard code with correct profile, however loop body is left unscaled. This leads to loop that exists more often then it is entered. This patch add slogic to scale the frequencies down and also to fix profile of original preheader where necesary.

As mentioned in PR 110202, GCC may be presented with input where control word of the VPTERNLOG intrinsic implies that some of its operands do not affect the result. In that case, we can eliminate redundant operands of the instruction by substituting any other operand in their place. This removes false dependencies. For instance, instead of (252 = 0xfc = _MM_TERNLOG_A | _MM_TERNLOG_B) vpternlogq $252, %zmm2, %zmm1, %zmm0 emit vpternlogq $252, %zmm0, %zmm1, %zmm0 When VPTERNLOG is invariant w.r.t first and second operands, and the third operand is memory, load memory into the output operand first, i.e. instead of (85 = 0x55 = ~_MM_TERNLOG_C) vpternlogq $85, (%rdi), %zmm1, %zmm0 emit vmovdqa64 (%rdi), %zmm0 vpternlogq $85, %zmm0, %zmm0, %zmm0 gcc/ChangeLog: PR target/110202 * config/i386/i386-protos.h (vpternlog_redundant_operand_mask): Declare.

This patch is inspired by Jakub's work on PR rtl-optimization/110717. The bitfield example described in comment #2, looks like: struct S { __int128 a : 69; }; unsigned type bar (struct S *p) { return p->a; } which on x86_64 with -O2 currently generates: bar: movzbl 8(%rdi), %ecx movq (%rdi), %rax andl $31, %ecx movq %rcx, %rdx salq $59, %rdx sarq $59, %rdx ret The ANDL $31 is interesting... we first extract an unsigned 69-bit bitfield by masking/clearing the top bits of the most significant word, and then it gets sign-extended, by left shifting and arithmetic right shifting. Obviously, this bit-wise AND is redundant, for signed bit-fields, we don't require these bits to be cleared, if we're about to set them appropriately. This patch eliminates this redundancy in the middle-end, during RTL expansion, but extending the extract_bit_field APIs so that the integer UNSIGNEDP argument takes a special value; 0 indicates the field should be sign extended, 1 (any non-zero value) indicates the field should be zero extended, but -1 indicates a third option, that we don't care how or whether the field is extended. By passing and checking this sentinel value at the appropriate places we avoid the useless bit masking (on all targets). For the test case above, with this patch we now generate: bar: movzbl 8(%rdi), %ecx movq (%rdi), %rax movq %rcx, %rdx salq $59, %rdx sarq $59, %rdx ret 2023-08-04 Roger Sayle <roger@nextmovesoftware.com> gcc/ChangeLog * expmed.cc (extract_bit_field_1): Document that an UNSIGNEDP value of -1 is equivalent to don't care.

This patch is the final piece in the series to improve the ABI issues affecting PR 88873. The previous patches tackled inserting DFmode values into V2DFmode registers, by introducing insvti_{low,high}part patterns. This patch improves the extraction of DFmode values from V2DFmode registers via TImode intermediates. I'd initially thought this would require new extvti_{low,high}part patterns to be defined, but all that's required is to recognize that the SUBREG idioms produced by combine are equivalent to (forms of) vec_select patterns. The target-independent middle-end can't be sure that the appropriate vec_select instruction exists on the target, hence doesn't canonicalize a SUBREG of a vector mode as a vec_select, but the backend can provide a define_split stating where and when this is useful, for example, considering whether the operand is in memory, or whether !TARGET_SSE_MATH and the destination is i387. For pr88873.c, gcc -O2 -march=cascadelake currently generates: foo: vpunpcklqdq %xmm3, %xmm2, %xmm7 vpunpcklqdq %xmm1, %xmm0, %xmm6 vpunpcklqdq %xmm5, %xmm4, %xmm2 vmovdqa %xmm7, -24(%rsp) vmovdqa %xmm6, %xmm1 movq -16(%rsp), %rax vpinsrq $1, %rax, %xmm7, %xmm4 vmovapd %xmm4, %xmm6 vfmadd132pd %xmm1, %xmm2, %xmm6 vmovapd %xmm6, -24(%rsp) vmovsd -16(%rsp), %xmm1 vmovsd -24(%rsp), %xmm0 ret with this patch, we now generate: foo: vpunpcklqdq %xmm1, %xmm0, %xmm6 vpunpcklqdq %xmm3, %xmm2, %xmm7 vpunpcklqdq %xmm5, %xmm4, %xmm2 vmovdqa %xmm6, %xmm1 vfmadd132pd %xmm7, %xmm2, %xmm1 vmovsd %xmm1, %xmm1, %xmm0 vunpckhpd %xmm1, %xmm1, %xmm1 ret The improvement is even more dramatic when compared to the original 29 instructions shown in comment #8.

The support for early break vectorization breaks lots of scan vect and slp testcases because they assume that loops with abort () in them cannot be vectorized. Additionally it breaks the point of having a scalar loop to check the output of the vectorizer if that loop is also vectorized. For that reason this adds vectorized using this patch series. FWIW, none of these tests were failing to vectorize or run before the pragma. The tests that did point to some issues were copies to the early break test suit as well. gcc/testsuite/ChangeLog: * g++.dg/vect/pr84556.cc: Add novector pragma. * g++.dg/vect/simd-1.cc: Add novector

FORTRAN currently has a pragma NOVECTOR for indicating that vectorization should not be applied to a particular loop. ICC/ICX also has such a pragma for C and C++ called #pragma novector. As part of this patch series I need a way to easily turn off vectorization of particular loops, particularly for testsuite reasons. This patch proposes a #pragma GCC novector that does the same for C as gfortan does for FORTRAN and what ICX/ICX does for C. I added only some basic tests here, but the next patch in the series uses this in the testsuite in about ~800 tests. gcc/c-family/ChangeLog: * c-pragma.h (enum pragma_kind): Add PRAGMA_NOVECTOR. * c-pragma.cc (init_pragma): Use it. gcc/c/ChangeLog: * c-parser.cc (c_parser_while_statement, c_parser_do_statement, c_parser_for_statement, c_parser_statement_after_labels, c_parse_pragma_novector, c_parser_pragma): Wire through novector and default to false. gcc/testsuite/ChangeLog: * gcc.dg/vect/vect-novector-pragma.c: New test.
