2023-11-09libstdc++: optimize bit iterators assuming normalization [PR110807]Alexandre Oliva1-3/+34
The representation of bit iterators, using a pointer into an array of words, and an unsigned bit offset into that word, makes for some optimization challenges: because the compiler doesn't know that the offset is always in a certain narrow range, beginning at zero and ending before the word bitwidth, when a function loads an offset that it hasn't normalized itself, it may fail to derive certain reasonable conclusions, even to the point of retaining useless calls that elicit incorrect warnings. Case at hand: The 110807.cc testcase for bit vectors assigns a 1-bit list to a global bit vector variable. Based on the compile-time constant length of the list, we decide in _M_insert_range whether to use the existing storage or to allocate new storage for the vector. After allocation, we decide in _M_copy_aligned how to copy any preexisting portions of the vector to the newly-allocated storage. When copying two or more words, we use __builtin_memmove. However, because we compute the available room using bit offsets without range information, even comparing them with constants, we fail to infer ranges for the preexisting vector depending on word size, and may thus retain the memmove call despite knowing we've only allocated one word. Other parts of the compiler then detect the mismatch between the constant allocation size and the much larger range that could theoretically be copied into the newly-allocated storage if we could reach the call. Ensuring the compiler is aware of the constraints on the offset range enables it to do a much better job at optimizing. Using attribute assume (_M_offset <= ...) didn't work, because gimple lowered that to something that vrp could only use to ensure 'this' was non-NULL. Exposing _M_offset as an automatic variable/gimple register outside the unevaluated assume operand enabled the optimizer to do its job. Rather than placing such load-then-assume constructs all over, I introduced an always-inline member function in bit iterators that does the job of conveying to the compiler the information that the assumption is supposed to hold, and various calls throughout functions pertaining to bit iterators that might not otherwise know that the offsets have to be in range, so that the compiler no longer needs to make conservative assumptions that prevent optimizations. With the explicit assumptions, the compiler can correlate the test for available storage in the vector with the test for how much storage might need to be copied, and determine that, if we're not asking for enough room for two or more words, we can omit entirely the code to copy two or more words, without any runtime overhead whatsoever: no traces remain of the undefined behavior or of the tests that inform the compiler about the assumptions that must hold. for libstdc++-v3/ChangeLog PR libstdc++/110807 * include/bits/stl_bvector.h (_Bit_iterator_base): Add _M_assume_normalized member function.

2023-11-09skip debug stmts when assigning locus discriminatorsAlexandre Oliva1-0/+16
c-c++-common/goacc/kernels-loop-g.c has been failing (compare-debug) on i686-linux-gnu since r13-3172, because the implementation enabled debug stmts to cause discriminators to be assigned differently, and the discriminators are printed in the .gkd dumps that -fcompare-debug compares. This patch prevents debug stmts from affecting the discriminators in nondebug stmts, but enables debug stmts to get discriminators just as nondebug stmts would if their line numbers match. I suppose we could arrange for discriminators to be omitted from the -fcompare-debug dumps, but keeping discriminators in sync is probably good to avoid other potential sources of divergence between debug and nondebug. for gcc/ChangeLog * tree-cfg.cc (assign_discriminators): Handle debug stmts.

2023-11-08i386: Apply LRA reload workaround to insns with high registers [PR82524]Uros Bizjak12-243/+673
LRA is not able to reload zero_extracted in-out operand with matched input operand in the same way as strict_low_part in-out operand. The patch applies the strict_low_part workaround, where we allow LRA to generate an instruction with non-matched input operand, which is split post reload to the instruction that inserts non-matched input operand to an in-out operand and the instruction that uses matched operand, also to zero_extracted in-out operand case. The generated code from the pr82524.c testcase improves from: movl %esi, %ecx movl %edi, %eax movsbl %ch, %esi addl %esi, %edx movb %dl, %ah to: movl %edi, %eax movl %esi, %ecx movb %ch, %ah addb %dl, %ah The compiler is now also able to handle non-commutative operations: movl %edi, %eax movl %esi, %ecx movb %ch, %ah subb %dl, %ah and unary operations: movl %edi, %eax movl %esi, %edx movb %dh, %ah negb %ah The patch also robustifies split condition of the splitters to ensure that only alternatives with unmatched operands are split.

2023-11-08TLC to vect_check_store_rhs and vect_slp_child_index_for_operandRichard Biener3-28/+31
This prepares us for the SLP of scatters. We have to tell vect_slp_child_index_for_operand whether we are dealing with a scatter/gather stmt so this adds an argument similar to the one we have for vect_get_operand_map. This also refactors vect_check_store_rhs to get the actual rhs and the associated SLP node instead of leaving that to the caller. * tree-vectorizer.h (vect_slp_child_index_for_operand): Add gatherscatter_p argument. * tree-vect-slp.cc (vect_slp_child_index_for_operand): Likewise.

2023-11-08RISC-V: Removed unnecessary sign-extend for vsetvlLehua Ding2-0/+72
Hi, This patch try to combine bellow two insns and then further remove unnecessary sign_extend operations. This optimization is borrowed from LLVM (https://godbolt.org/z/4f6v56xej): (set (reg:DI 134 [ _1 ]) (unspec:DI [ (const_int 19 [0x13]) (const_int 8 [0x8]) (const_int 5 [0x5]) (const_int 2 [0x2]) repeated x2 ] UNSPEC_VSETVL)) (set (reg/v:DI 135 [ <retval> ]) (sign_extend:DI (subreg:SI (reg:DI 134 [ _1 ]) 0))) The reason we can remove signe_extend is because currently the vl value returned by the vsetvl instruction ranges from 0 to 65536 (uint16_t), and bits 17 to 63 (including 31) are always 0, so there is no change after sign_extend. Note that for HI and QI modes we cannot do this. Of course, if the range returned by vsetvl later expands to 32 bits, then this combine pattern needs to be removed. But that could be a long time from now. gcc/ChangeLog: * config/riscv/vector.md (*vsetvldi_no_side_effects_si_extend): New combine pattern. gcc/testsuite/ChangeLog: * gcc.target/riscv/rvv/vsetvl/vsetvl_int.c: New test.

2023-11-08libgfortran: Remove empty array descriptor first dimension overwrite [PR112371]Mikael Morin189-2714/+1100
Remove the forced overwrite of the first dimension of the result array descriptor to set it to zero extent, in the function templates for transformational functions doing an array reduction along a dimension. This overwrite, which happened before early returning in case the result array was empty, was wrong because an array may have a non-zero extent in the first dimension and still be empty if it has a zero extent in a higher dimension. Overwriting the dimension was resulting in wrong array result upper bound for the first dimension in that case. The offending piece of code was present in several places, and this removes them all. More precisely, there is only one case to fix for logical reduction functions, and there are three cases for other reduction functions, corresponding to non-masked reduction, reduction with array mask, and reduction with scalar mask. The impacted m4 files are ifunction_logical.m4 for logical reduction functions, ifunction.m4 for regular functions and types, ifunction-s.m4 for character minloc and maxloc, ifunction-s2.m4 for character minval and maxval, and ifindloc1.m4 for findloc.

2023-11-08libgfortran: Remove early return if extent is zero [PR112371]Mikael Morin145-288/+495
Remove the early return present in function templates for transformational functions doing a (masked) reduction of an array along a dimension. This early return, which triggered if the extent in the reduction dimension was zero, was wrong because even if the reduction operation degenerates to a constant value in that case, one has to loop anyway along the other dimensions to initialize every element of the resulting array with that constant value. The case of negative extent (not sure whether it may happen in practice) which was also early returning, is handled by clamping to zero. The offending piece of code was present in several places, and this removes them all. Namely, the impacted m4 files are ifunction.m4 for regular functions and types, ifunction-s.m4 for character minloc and maxloc, and ifunction-s2.m4 for character minval and maxval.

2023-11-08libgfortran: Don't skip allocation if size is zero [PR112412]Mikael Morin161-752/+499
In the function template of transformational functions doing a reduction of an array along one dimension, if the passed in result array was unallocated and the calculated allocation size was zero (this is the case of empty result arrays), an early return used to skip the allocation. This change moves the allocation before the early return, so that empty result arrays are not seen as unallocated. This is possible because zero size is explicitly supported by the allocation function. The offending code is present in several places, and this updates them all. More precisely, there is one place in the template for logical reductions, and there are two places in the templates corresponding to masked reductions with respectively array mask and scalar mask. Templates for unmasked reductions, which already allocate before returning, are not affected, but unmasked reductions are checked nevertheless in the testcase. The affected m4 files are ifunction.m4 for regular functions and types, ifunction-s.m4 for character minloc and maxloc, ifunction-s2.m4 for character minval and maxval, and ifunction_logical for logical reductions.

2023-11-08RISC-V: Normalize user vsetvl intrinsics[PR112092]Juzhe-Zhong13-22/+83
Since our user vsetvl intrinsics are defined as just calculate the VL output which is the number of the elements to be processed. Such intrinsics do not have any side effects. We should normalize them when they have same ratio. E.g __riscv_vsetvl_e8mf8 result is same as __riscv_vsetvl_e64m1. Normalize them can allow us have better codegen. Consider this following example: #include "riscv_vector.h" void foo(int32_t *in1, int32_t *in2, int32_t *in3, int32_t *out, size_t n, int cond, int avl) { size_t vl; if (cond) vl = __riscv_vsetvl_e32m1(avl); else vl = __riscv_vsetvl_e16mf2(avl); for (size_t i = 0; i < n; i += 1) { vint32m1_t a = __riscv_vle32_v_i32m1(in1, vl); vint32m1_t b = __riscv_vle32_v_i32m1_tu(a, in2, vl); vint32m1_t c = __riscv_vle32_v_i32m1_tu(b, in3, vl); __riscv_vse32_v_i32m1(out, c, vl); } } Before this patch: foo: beq a5,zero,.L2 vsetvli a6,a6,e32,m1,tu,ma .L3: li a5,0 beq a4,zero,.L9 .L4: vle32.v v1,0(a0) addi a5,a5,1 vle32.v v1,0(a1) vle32.v v1,0(a2) vse32.v v1,0(a3) bne a4,a5,.L4 .L9: ret .L2: vsetvli zero,a6,e32,m1,tu,ma j .L3 After this patch: foo: li a5,0 vsetvli zero,a6,e32,m1,tu,ma beq a4,zero,.L9 .L4: vle32.v v1,0(a0) addi a5,a5,1 vle32.v v1,0(a1) vle32.v v1,0(a2) vse32.v v1,0(a3) bne a4,a5,.L4 .L9: ret PR target/112092 gcc/ChangeLog: * config/riscv/riscv-vector-builtins-bases.cc: Normalize the vsetvls. gcc/testsuite/ChangeLog: * gcc.target/riscv/rvv/vsetvl/pr109743-1.c: Adapt test. * gcc.target/riscv/rvv/vsetvl/pr109743-3.c: Ditto. * gcc.target/riscv/rvv/vsetvl/vsetvl-11.c: Ditto. * gcc.target/riscv/rvv/vsetvl/vsetvl-15.c: Ditto. * gcc.target/riscv/rvv/vsetvl/vsetvl-22.c: Ditto. * gcc.target/riscv/rvv/vsetvl/vsetvlmax-13.c: Ditto. * gcc.target/riscv/rvv/vsetvl/vsetvlmax-15.c: Ditto. * gcc.target/riscv/rvv/vsetvl/vsetvlmax-5.c: Ditto. * gcc.target/riscv/rvv/vsetvl/vsetvlmax-7.c: Ditto. * gcc.target/riscv/rvv/vsetvl/vsetvlmax-8.c: Ditto. * gcc.target/riscv/rvv/vsetvl/pr112092-1.c: New test. * gcc.target/riscv/rvv/vsetvl/pr112092-2.c: New test.

Completing the move to refer to C23 in place of C2X, rename all tests with "c2x" or "gnu2x" in their names to use "c23" or "gnu23" instead. 17 files in the testsuite that referred to such tests (or, in one case, a generated .i file to be scanned) by those names are updated for the renaming. Bootstrapped with no regressions for x86_64-pc-linux-gnu. gcc/testsuite/ * gcc.dg/atomic/c2x-stdatomic-lockfree-char8_t.c: Move to ... * gcc.dg/atomic/c23-stdatomic-lockfree-char8_t.c: ... here. * gcc.dg/atomic/c2x-stdatomic-var-init-1.c: Move to ... * gcc.dg/atomic/c23-stdatomic-var-init-1.c: ... here. * gcc.dg/atomic/gnu2x-stdatomic-lockfree-char8_t.c: Move to ... * gcc.dg/atomic/gnu23-stdatomic-lockfree-char8_t.c: ... here.

2023-11-07Fix libgomp build on targets that are not Linux-based or acceleratorsKwok Cheung Yeung1-0/+0
The patch 'openmp: Add support for the 'indirect' clause in C/C++' introduced a new file target-indirect.c into the Makefile sources, but that file was only present in config/linux/ and config/accel/, so targets that are not Linux-based or GPU accelerators will not pick it up and fail to build. This is fixed by making the version in config/linux/ the default by moving it into the base directory of libgomp. 2023-11-07 Kwok Cheung Yeung <kcy@codesourcery.com> libgomp/ * config/linux/target-indirect.c: Move to... * target-indirect.c: ...here.
2023-11-07testsuite: Refer more consistently to C23 not C2XJoseph Myers406-607/+607
Continuing the move to refer to C23 in place of C2X throughout the source tree, update testcase contents to use the "c23" or "gnu23" option names in place of the old "c2x" or "gnu2x" names, except for the few tests specifically intended to test the old names, and to refer to C23 in comments. This updates testcase *contents*; testcase naming (renaming c2x-* tests to c23-* and gnu2x-* tests to gnu23-*), with a few consequent changes to contents (where tests #include other tests, or refer to them by name in comments) is to be addressed separately. Bootstrapped with no regressions for x86_64-pc-linux-gnu. gcc/testsuite/ * c-c++-common/alias-1.c: Use "c23" or "gnu23" option names in place of "c2x" or "gnu2x" names, and refer to C23 in comments in

The following makes the C++98 locale init path follow the way the C++11 performs initialization. This way we deal with pthread_once failing, falling back to non-threadsafe initialization which, given we initialize from the library, should be serialized by the dynamic loader already.

2023-11-07testsuite: check for and use -mno-strict-align where neededAlexandre Oliva36-0/+81
Various tests fail on powerpc if the toolchain is configured to enable -mstrict-align by default. This patch introduces -mno-strict-align on tests found to fail that way, when the target supports this option. I suppose !non_strict_align could be used to skip tests, instead of or in addition to this tweak, and that might be desirable if they still fail on targets that do no support -mno-strict-align, but I haven't observed such scenarios. The p9-vec-length tests expect vectorization on loop bodies and epilogues that reference arrays that are not known to be more aligned than their small element types. Though VSX vectors work best with 32- or 64-bit alignment, unaligned vector loads and stores are expected by the tests. However, with -mstrict-align by default, vector loads and stores not known to be aligned end up open coded, which doesn't match the asm output expectations coded in the tests. for gcc/ChangeLog * doc/sourcebuild.texi (opt_mstrict_align): New target. for gcc/testsuite/ChangeLog * lib/target-supports.exp (check_effective_target_opt_mstrict_align): New. * gcc.dg/strlenopt-80.c: Add -mno-strict-align if supported. * gcc.target/powerpc/prefix-ds-dq.c: Likewise. * gcc.target/powerpc/p9-vec-length-epil-1.c: Likewise. * gcc.target/powerpc/p9-vec-length-epil-2.c: Likewise. * gcc.target/powerpc/p9-vec-length-epil-3.c: Likewise. * gcc.target/powerpc/p9-vec-length-epil-4.c: Likewise. * gcc.target/powerpc/p9-vec-length-epil-5.c: Likewise. * gcc.target/powerpc/p9-vec-length-epil-6.c: Likewise. * gcc.target/powerpc/p9-vec-length-epil-7.c: Likewise. * gcc.target/powerpc/p9-vec-length-epil-8.c: Likewise. * gcc.target/powerpc/p9-vec-length-epil-run-1.c: Likewise. * gcc.target/powerpc/p9-vec-length-epil-run-2.c: Likewise. * gcc.target/powerpc/p9-vec-length-epil-run-3.c: Likewise. * gcc.target/powerpc/p9-vec-length-epil-run-4.c: Likewise. * gcc.target/powerpc/p9-vec-length-epil-run-5.c: Likewise. * gcc.target/powerpc/p9-vec-length-epil-run-6.c: Likewise. * gcc.target/powerpc/p9-vec-length-epil-run-7.c: Likewise. * gcc.target/powerpc/p9-vec-length-epil-run-8.c: Likewise. * gcc.target/powerpc/p9-vec-length-full-1.c: Likewise. * gcc.target/powerpc/p9-vec-length-full-2.c: Likewise. * gcc.target/powerpc/p9-vec-length-full-3.c: Likewise. * gcc.target/powerpc/p9-vec-length-full-4.c: Likewise. * gcc.target/powerpc/p9-vec-length-full-5.c: Likewise. * gcc.target/powerpc/p9-vec-length-full-6.c: Likewise. * gcc.target/powerpc/p9-vec-length-full-7.c: Likewise. * gcc.target/powerpc/p9-vec-length-full-8.c: Likewise. * gcc.target/powerpc/p9-vec-length-full-run-1.c: Likewise. * gcc.target/powerpc/p9-vec-length-full-run-2.c: Likewise. * gcc.target/powerpc/p9-vec-length-full-run-3.c: Likewise. * gcc.target/powerpc/p9-vec-length-full-run-4.c: Likewise. * gcc.target/powerpc/p9-vec-length-full-run-5.c: Likewise. * gcc.target/powerpc/p9-vec-length-full-run-6.c: Likewise. * gcc.target/powerpc/p9-vec-length-full-run-7.c: Likewise. * gcc.target/powerpc/p9-vec-length-full-run-8.c: Likewise.

2023-11-07ada: Compiler crash on early alignment clauseBob Duff2-4/+1
This patch fixes a bug: if "for T'Alignment use..." is followed by "for T use (<enum rep>);" the compiler crashes. A workaround is to move the alignment clause after the enumeration rep clause. gcc/ada/ * sem_ch13.ads (Set_Enum_Esize): Do not set alignment. * sem_ch13.adb (Set_Enum_Esize): Do not set alignment. Archaeology seems to show that this line of code dates from when "Alignment = 0" meant "the Alignment is not known at compile time" and "the Alignment is not yet known at compile time" as well as "the Alignment is zero". In any case, it seems to be unnecessary, and in this case harmful, because gigi would crash. Alignment_Clause is set (because there is one), so gigi would query the Alignment, but Alignment was destroyed.
