2020-05-13Fix -fcompare-debug issue in purge_dead_edges [PR95080]Jakub Jelinek4-1/+49
The following testcase fails with -fcompare-debug, the bug used to be latent since introduction of -fcompare-debug. The loop at the start of purge_dead_edges behaves differently between -g0 and -g - if the last insn is a DEBUG_INSN, then it skips not just DEBUG_INSNs but also NOTEs until it finds some other real insn (or bb head), while with -g0 it will not skip any NOTEs, so if we have real_insn note debug_insn // not present with -g0 then with -g it might remove useless REG_EH_REGION from real_insn, while with -g0 it will not. Yet another option would be not skipping NOTE_P in the loop; I couldn't find in history rationale for why it is done. 2020-05-13 Jakub Jelinek <jakub@redhat.com> PR debug/95080 * cfgrtl.c (purge_dead_edges): Skip over debug and note insns even if the last insn is a note. * g++.dg/opt/pr95080.C: New test.
2020-05-13Fold single imm use of a FMA if it is a negation [PR95060]Jakub Jelinek28-144/+226
match.pd already has simplifications for negation of a FMA (FMS, FNMA, FNMS) call if it is single use, but when the widening_mul pass discovers FMAs, nothing folds the statements anymore. So, the following patch adjusts the widening_mul pass to handle that. I had to adjust quite a lot of tests, because they have in them nested FMAs (one FMA feeding another one) and the patch results in some (equivalent) changes in the chosen instructions, previously the negation of one FMA's result would result in the dependent FMA being adjusted for the negation, but now instead the first FMA is adjusted. 2020-05-13 Jakub Jelinek <jakub@redhat.com> PR tree-optimization/95060 * tree-ssa-math-opts.c (convert_mult_to_fma_1): Fold a NEGATE_EXPR if it is the single use of the FMA internal builtin. * gcc.target/i386/avx512f-pr95060.c: New test. * gcc.target/i386/fma_double_1.c: Adjust expected insn counts. * gcc.target/i386/fma_double_2.c: Likewise. * gcc.target/i386/fma_double_3.c: Likewise. * gcc.target/i386/fma_double_4.c: Likewise. * gcc.target/i386/fma_double_5.c: Likewise. * gcc.target/i386/fma_double_6.c: Likewise. * gcc.target/i386/fma_float_1.c: Likewise. * gcc.target/i386/fma_float_2.c: Likewise. * gcc.target/i386/fma_float_3.c: Likewise. * gcc.target/i386/fma_float_4.c: Likewise. * gcc.target/i386/fma_float_5.c: Likewise. * gcc.target/i386/fma_float_6.c: Likewise. * gcc.target/i386/l_fma_double_1.c: Likewise. * gcc.target/i386/l_fma_double_2.c: Likewise. * gcc.target/i386/l_fma_double_3.c: Likewise. * gcc.target/i386/l_fma_double_4.c: Likewise. * gcc.target/i386/l_fma_double_5.c: Likewise. * gcc.target/i386/l_fma_double_6.c: Likewise. * gcc.target/i386/l_fma_float_1.c: Likewise. * gcc.target/i386/l_fma_float_2.c: Likewise. * gcc.target/i386/l_fma_float_3.c: Likewise. * gcc.target/i386/l_fma_float_4.c: Likewise. * gcc.target/i386/l_fma_float_5.c: Likewise. * gcc.target/i386/l_fma_float_6.c: Likewise.

2020-05-13x86-vxworks malloc aligns to 8 bytes like solarisAlexandre Oliva3-5/+15
Vxworks 7's malloc, like Solaris', only ensures 8-byte alignment of returned pointers on 32-bit x86, though GCC's stddef.h defines max_align_t with 16-byte alignment for __float128. This patch enables on x86-vxworks the same memory_resource workaround used for x86-solaris. The testsuite also had a workaround, defining BAD_MAX_ALIGN_T and xfailing the test; extend those to x86-vxworks as well, and remove the check for char-aligned requested allocation to be aligned like max_align_t. With that change, the test passes on x86-vxworks; I'm guessing that's the same reason for the test not to pass on x86-solaris (and on x86_64-solaris -m32), so with the fix, I'm tentatively removing the xfail. for libstdc++-v3/ChangeLog PR libstdc++/77691 * include/experimental/memory_resource (__resource_adaptor_imp::do_allocate): Handle max_align_t on x86-vxworks as on x86-solaris.

2020-05-12preprocessor: EOF location is at end of file [PR95013]Nathan Sidwell58-64/+168
My recent C++ parser change to pay attention to EOF location uncovered a separate bug. The preprocesor's EOF logic would set the EOF location to be the beginning of the last line of text in the file -- not the 'line' after that, which contains no characters. Mostly. This fixes things so that when we attempt to read the last line of the main file, we don't pop the buffer until the tokenizer has a chance to create an EOF token with the correct location information. It is then responsible for popping the buffer. As it happens, raw string literal tokenizing contained a bug -- it would increment the line number prematurely, because it cached buffer->cur in a local variable, but checked buffer->cur before updating it to figure out if it was at end of file. We fix up that too. The EOF token intentionally doesn't have a column number -- it's not a position on a line, it's a non-existant line. The testsuite churn is just correcting the EOF location diagnostics. libcpp/ PR preprocessor/95013 * lex.c (lex_raw_string): Process line notes before incrementing. Correct incrementing condition.

2020-05-12c++: Function found via ADL when it should not [PR95074]Marek Polacek4-10/+73
I noticed that we don't implement [basic.lookup.argdep]/3: quite correctly; it says "If X (the lookup set produced by unqualified lookup) contains -- a block-scope function declaration that is not a using-declaration [...] then Y (the lookup set produced by ADL) is empty." but we were still performing ADL in fn1 in the attached test. The problem was that we were only looking at the first function in the overload set which in this case happened to be a using-declaration, and those don't suppress ADL. We have to look through the whole set to find out if unqualified lookup found a block-scope function declaration, or a member function declaration. PR c++/95074 * parser.c (cp_parser_postfix_expression) <case CPP_OPEN_PAREN>: When looking for a block-scope function declaration, look through the whole set, not just the first function in the overload set. * g++.dg/lookup/koenig15.C: New test.

2020-05-12Fix throw specifiers on interface.Nathan Sidwell3-17/+38
I discovered that libitm: (a) declares __cxa_allocate_exception and friends directly, (b) doesn't mark them as 'throw()' (c) doesn't mark the replacment fns _ITM_$foo as nothrow either We happen to get away with it because of code in the compiler that, although it checks the parameter types, doesn't check the exception specification. (One reason being they used to not be part of the language's type system, but now they are.) I suspect this can lead us to generate pessimal code later, if we've seen one of these decls earlier. Anyway, with modules it becomes trickier[*], so I'm trying to clean it up and not be a problem. I see Jakub fixed part of the problem (https://gcc.gnu.org/pipermail/gcc-patches/2018-December/513302.html) AFAICT, he did fix libitm's decls, but left the lax parm-type checking in the compiler. libitm.h is not very informative about specification: in version 1 of http://www.intel.com/some/path/here.pdf. */ Anyway, it was too fiddly to have libitm pick up the declarations from libsupc++. Besides it makes them weak declarations, and then provides definitions for non-elf systems. So this patch adds the expected 'throw()' * libitm/libitm.h (_ITM_NOTHROW): Define.
