2022-03-02testsuite: Add testcases for already fixed PR [PR100541]Jakub Jelinek2-0/+49
These testcases started failing with r12-630 and one of them got fixed with r12-4531 (aka PR102764 fix and r12-4616 further improved the fix) and the other went latent in r12-2591 (i.e. threader changes) and I believe was fixed for real by the PR102764 fix too. 2022-03-02 Jakub Jelinek <jakub@redhat.com> PR debug/100541 * g++.dg/opt/pr100541-1.C: New test. * g++.dg/opt/pr100541-2.C: New test.

2022-03-01warn-access: Fix up check_pointer_uses [PR104715]Jakub Jelinek2-3/+38
The following testcase emits bogus -Wdangling-pointer warnings. The bug is that when it sees that ptr immediate use is a call that returns one of its arguments, it will assume that the return value is based on ptr, but that is the case only if ptr is passed to the argument that is actually returned (so e.g. for memcpy the first argument, etc.). When the builtins guarantee e.g. that the result is based on the first argument (either ERF_RETURNS_ARG 0 in which case it will always just returns the first argument as is, or when it is something like strstr or strpbrk or mempcpy that it returns some pointer based on the first argument), it means the result is not based on second or following argument if any. The second hunk fixes this. The first hunk just removes an unnecessary TREE_CODE check, the code only pushes SSA_NAMEs into the pointers vector and if it didn't, it uses FOR_EACH_IMM_USE_FAST (use_p, iter, ptr) a few lines below this, which of course requires that ptr is a SSA_NAME. Tree checking on SSA_NAME_VERSION will already ensure that if it wasn't a SSA_NAME, we'd ICE. 2022-03-01 Jakub Jelinek <jakub@redhat.com> PR tree-optimization/104715 * gimple-ssa-warn-access.cc (pass_waccess::check_pointer_uses): Don't unnecessarily test if ptr is a SSA_NAME, it has to be.

2022-02-28PR tree-optimization/91384: peephole2 to eliminate testl after negl.Roger Sayle2-0/+33
This patch is my proposed solution to PR tree-optimization/91384 which is a missed-optimization/code quality regression on x86_64. The problematic idiom is "if (r = -a)" which is equivalent to both "r = -a; if (r != 0)" and alternatively "r = -a; if (a != 0)". In this particular case, on x86_64, we prefer to use the condition codes from the negation, rather than require an explicit testl instruction. Unfortunately, combine can't help, as it doesn't attempt to merge pairs of instructions that share the same operand(s), only pairs/triples of instructions where the result of each instruction feeds the next. But I doubt there's sufficient benefit to attempt this kind of "combination" (that wouldn't already be caught by the tree-ssa passes). Fortunately, it's relatively easy to fix this up (addressing the regression) during peephole2 to eliminate the unnecessary testl in: movl %edi, %ebx negl %ebx testl %edi, %edi je .L2 2022-02-28 Roger Sayle <roger@nextmovesoftware.com> gcc/ChangeLog PR tree-optimization/91384 * config/i386/i386.md (peephole2): Eliminate final testl insn from the sequence *movsi_internal, *negsi_1, *cmpsi_ccno_1 by transforming using *negsi_2 for the negation. gcc/testsuite/ChangeLog PR tree-optimization/91384 * gcc.target/i386/pr91384.c: New test case.
2022-02-28PR middle-end/80270: ICE in extract_bit_field_1Roger Sayle2-0/+25
This patch fixes PR middle-end/80270, an ICE-on-valid regression, where performing a bitfield extraction on a variable explicitly stored in a hard register by the user causes a segmentation fault during RTL expansion. Nearly identical source code without the "asm" qualifier compiles fine. The point of divergence is in simplify_gen_subreg which tries to avoid creating non-trivial SUBREGs of hard registers, to avoid problems during register allocation. This suggests the simple solution proposed here, to copy hard registers to a new pseudo in extract_integral_bit_field, just before calling simplify_gen_subreg. 2022-02-28 Roger Sayle <roger@nextmovesoftware.com> Eric Botcazou <ebotcazou@adacore.com> gcc/ChangeLog PR middle-end/80270 * expmed.cc (extract_integral_bit_field): If OP0 is a hard register, copy it to a pseudo before calling simplify_gen_subreg. gcc/testsuite/ChangeLog * gcc.target/i386/pr80270.c: New test case.
2022-02-28[PR104637] LRA: Split hard regs as many as possible on one subpassVladimir N. Makarov2-7/+57
LRA hard reg split subpass is a small subpass used as the last resort for LRA when it can not assign a hard reg to a reload pseudo by other ways (e.g. by spilling non-reload pseudos). For simplicity the subpass works on one split base (as each split changes pseudo live range info). In this case it results in reaching maximal possible number of subpasses. The patch implements as many non-overlapping hard reg splits splits as possible on each subpass. gcc/ChangeLog: PR rtl-optimization/104637 * lra-assigns.cc (lra_split_hard_reg_for): Split hard regs as many as possible on one subpass. gcc/testsuite/ChangeLog: PR rtl-optimization/104637 * gcc.target/i386/pr104637.c: New.

2022-02-28c++: Lost deprecated/unavailable attr in class tmpl [PR104682]Marek Polacek7-6/+133
When looking into the other PR I noticed that we fail to give a warning for a deprecated enumerator when the enum is in a class template. This only happens when the attribute doesn't have an argument. The reason is that when we tsubst_enum, we create a new enumerator: build_enumerator (DECL_NAME (decl), value, newtag, DECL_ATTRIBUTES (decl), DECL_SOURCE_LOCATION (decl)); but DECL_ATTRIBUTES (decl) is null when the attribute was provided without an argument -- in that case it simply melts into a tree flag. handle_deprecated_attribute has: if (!args) *no_add_attrs = true; so the attribute isn't retained and we lose it when tsubsting. Same thing when the attribute is on the enum itself. Attribute unavailable is a similar case, but it's different in that it can be a late attribute whereas "deprecated" can't: is_late_template_attribute has /* But some attributes specifically apply to templates. */ && !is_attribute_p ("abi_tag", name) && !is_attribute_p ("deprecated", name) && !is_attribute_p ("visibility", name)) return true; else return false; which looks strange, but attr-unavailable-9.C tests that we don't error when the attribute is applied on a template.

2022-02-28[nvptx] Add -mptx=_Tom de Vries3-1/+6
Add an -mptx=_ value, that indicates the default ptx version. It can be used to undo an explicit -mptx setting, so this: ... $ gcc test.c -mptx=3.1 -mptx=_ ... has the same effect as: ... $ gcc test.c ... Tested on nvptx. gcc/ChangeLog: 2022-02-28 Tom de Vries <tdevries@suse.de> * config/nvptx/nvptx-opts.h (enum ptx_version): Add PTX_VERSION_default. * config/nvptx/nvptx.cc (handle_ptx_version_option): Handle PTX_VERSION_default. * config/nvptx/nvptx.opt: Add EnumValue "_" / PTX_VERSION_default.

2022-02-28rtl-optimization/104686 - speed up conflict iterationRichard Biener1-4/+6
The following replaces /* Skip bits that are zero. */ for (; (word & 1) == 0; word >>= 1) bit_num++; idioms in ira-int.h in the attempt to speedup update_conflict_hard_regno_costs which we're bound on in PR104686. The trick is to use ctz_hwi here which should pay off even with dense bitmaps on architectures that have HW support for this. For the PR in question this speeds up compile-time from 31s to 24s for me. 2022-02-25 Richard Biener <rguenther@suse.de> PR rtl-optimization/104686 * ira-int.h (minmax_set_iter_cond): Use ctz_hwi to elide loop skipping bits that are zero. (ira_object_conflict_iter_cond): Likewise.

2022-02-25match.pd: Further complex simplification fixes [PR104675]Jakub Jelinek2-2/+31
Mark mentioned in the PR further 2 simplifications that also ICE with complex types. For these, eventually (but IMO GCC 13 materials) we could support it for vector types if it would be uniform vector constants. Currently integer_pow2p is true only for INTEGER_CSTs and COMPLEX_CSTs and we can't use bit_and etc. for complex type. 2022-02-25 Jakub Jelinek <jakub@redhat.com> Marc Glisse <marc.glisse@inria.fr> PR tree-optimization/104675 * match.pd (t * 2U / 2 -> t & (~0 / 2), t / 2U * 2 -> t & ~1): Restrict simplifications to INTEGRAL_TYPE_P. * gcc.dg/pr104675-3.c : New test.
2022-02-25rs6000: Use rs6000_emit_move in movmisalign<mode> expander [PR104681]Jakub Jelinek2-1/+23
The following testcase ICEs, because for some strange reason it decides to use movmisaligntf during expansion where the destination is MEM and source is CONST_DOUBLE. For normal mov<mode> expanders the rs6000 backend uses rs6000_emit_move to ensure that if one operand is a MEM, the other is a REG and a few other things, but for movmisalign<mode> nothing enforced this. The middle-end documents that movmisalign<mode> shouldn't fail, so we can't force that through predicates or condition on the expander. 2022-02-25 Jakub Jelinek <jakub@redhat.com> PR target/104681 * config/rs6000/vector.md (movmisalign<mode>): Use rs6000_emit_move. * g++.dg/opt/pr104681.C: New test.
