2020-07-27mmix: Don't turn off .hidden support.Hans-Peter Nilsson2-12/+0
In 2012 e2769e908a915ebbc/r192344, I added the following lines, that I now delete. I've changed my mind: ELF-related targets based on gas, that support only static linking, have .hidden "for free", regardless of the visibility of the hidden object in the linked executable. No regressions for mmix-knuth-mmixware and "fixes": FAIL: gcc.dg/torture/pr94947-1.c -O2 -flto -fuse-linker-plugin -fno-fat-lto-objects (test for excess errors) Excess errors: lto1: warning: visibility attribute not supported in this configuration; ignored [-Wattributes] ...a warning which is emitted for "all" LTO tests (of which most have warnings filtered out); LTO "thinks" all supported targets have .hidden support. gcc: * configure.ac (out-of-tree linker .hidden support): Don't turn off for mmix-knuth-mmixware. * configure: Regenerate.

2020-07-26rs6000: add option -mblock-ops-unaligned-vsxAaron Sawdey3-0/+22
This option is mostly being added to provide -mno-block-ops-unaligned-vsx. The default is set the same as -mefficient-unaligned-vsx. This option will control the use of unaligned VSX loads/stores in the inline expansion of memcpy() and memmove(). The use case for this would be if you're compiling code that is doing a memcpy to memory mapped device memory that is cache-inhibited. On some powerpc processors this requires the unaligned vsx ops to be emulated by the kernel which is very slow. gcc/ChangeLog: * config/rs6000/rs6000.c (rs6000_option_override_internal): Set the default value for -mblock-ops-unaligned-vsx. * config/rs6000/rs6000.opt: Add -mblock-ops-unaligned-vsx. * doc/invoke.texi: Document -mblock-ops-unaligned-vsx.
2020-07-26gcc.dg/tree-ssa/forwprop-36.c: Adjust for mmixHans-Peter Nilsson1-1/+2
The label of interest here is "b.0_2" for e.g. x86_64-pc-linux-gnu but "b::1_2" for mmix-knuth-mmixware. The test seems to be of some interest for mmix (hey, gcc open-coded 128-bit integer support behind my back!) so I didn't want to just disable it. I also didn't want to obscure the matching pattern by generalizing it, so instead I added a separate matching pattern. gcc/testsuite: * gcc.dg/tree-ssa/forwprop-36.c: Adjust for mmix.
2020-07-26gcc.dg/torture/pr59330.c: Disable for mmixHans-Peter Nilsson1-0/+1
With the dejagnu status-wrapper, there's a reference to write in each executable, which for mmix in newlib has a reference to a variable defined in open, which for mmix in newlib has a reference to sprintf (oops!) and the dependency-chain goes on; ad finitum there's a reference to malloc, which in default newlib is colocated with free; the same file newlib/libc/stdlib/malloc.c. Not being compiled with -ffunction-sections, they're emitted in the same section (.text) and thus inseparable: you can't override just one of them as in this test, or else you'll get: <X>/pre/mmix/bin/ld: <X>/gccobj/mmix/./newlib/libc.a(lib_a-malloc.o): in function `free': <X>/gcc/newlib/libc/stdlib/malloc.c:169: multiple definition of `free'; /tmp/ccvRA0zb.o:(.text+0x0): first defined here collect2: error: ld returned 1 exit status compiler exited with status 1 FAIL: gcc.dg/torture/pr59330.c -O0 (test for excess errors) I'm using a dg-skip-if here instead of starting a hardly scalable dg-do target selector. I'm not keying on effective-target unwrapped because the dependency-chain is target-specific rather than dejagnu status-wrapper-specific. gcc/testsuite: * gcc.dg/torture/pr59330.c: Disable for mmix.

2020-07-25config/mmix/mmix.c (TARGET_ASM_OUTPUT_IDENT): Override.Hans-Peter Nilsson1-0/+3
Funny that default_asm_output_ident_directive isn't the default... Anyway, since dot-pseudos like .ident are treated as comments by mmixal, there's nothing lost compatibilitywise by supporting it. If mmix-knuth-mmixware had included elfos.h this'd have been the default. There might be enough reason to do that; relocatable objects are ELF but (by default) links to produce mmo. Fixes c-c++-common/ident-1b.c and 2b in C and C++ testing. Committed. gcc: * config/mmix/mmix.c (TARGET_ASM_OUTPUT_IDENT): Override the default with default_asm_output_ident_directive.
2020-07-25C++, testsuite: Adjust pure-virtual1.C options for Darwin.Iain Sandoe1-0/+1
Darwin's static linker expects, by default, that all linkage will be satisfied (even for weak items). This allows the two-level namespace to work even for weak cases. However, there's an option to make it behave in a similar manner to ELF. This is needed for the pure-virtual1.C testcase to pass on Darwin. gcc/testsuite/ChangeLog: * g++.dg/abi/pure-virtual1.C: Add dynamic_lookup option for Darwin.

The only way to enable or disable Power10 insns (ISA 3.1 insns) should be via the -mcpu= switch. This patch disables the -mpower10 options the same way the -mdirect-move switch is neutered already.

2020-07-24testsuite: Adjust patchable_function tests for mmix.Hans-Peter Nilsson3-3/+3
There's no reason anyone would want to use the "patchable function" feature for MMIX and also no reason to exclude those tests. For MMIX, the NOP equivalent is SWYM ("swymming" is a healthy exercise). Text-wise, making the tests pass by adjusting the regexp, is shorter, and it seems unlikely to both appear as a mnemonic for other targets *and* being emitted in uppercase. gcc/testsuite: * c-c++-common/patchable_function_entry-decl.c, c-c++-common/patchable_function_entry-default.c, c-c++-common/patchable_function_entry-definition.c: Adjust for mmix.

This test case, extracted from PR 95645, was failing because alignment of local long long variable got lowered from 8 bytes to 4 bytes in adjust alignment pass, which triggered assert failure. This test case passes now because PR 95237 fix only allows lowering of alignment of local variables in the front end.

2020-07-24[PR96230] some -dumpbase-ext fixesAlexandre Oliva2-7/+31
The initial bug report was that compiling (-c) with -dumpbase "" -dumpbase-ext .<ext> crashes the driver. The verification of -dumpbase-ext against -dumpbase doesn't cover the case in which -dumpbase activates backward-compatibility mode. I added a test for that, and for -dumpbase-ext without -dumpbase, trying to make it work in a sensible way, as if applied to the default -dumpbase for each file. It turned out that this made for too much complexity in dealing with suffixes derived from input filenames, so I gave that up and returned to discarding -dumpbase-ext as documented, ending up with a change identical to that in the original bug report. I also thought I caught an off-by-one error in the initial verification, that caused dumpbase_ext to be discarded if it was identical to the specified dumpbase, but that turned out to be intentional as well, so I put in comments and a test to reflect it. Finally, an earlier version of the newly-added tests used "$var.ext" in an expected output list, which showed me the handling of string expansion was incorrect. Reworked the expr into an eval to make that work, and, absent any reliance on post-eval adjustments to so-expanded output names, I arranged for the adjustments to be skipped after eval. Co-Authored-By: "Zhanghaijian (A)" <z.zhanghaijian@huawei.com> for gcc/ChangeLog PR driver/96230 * gcc.c (process_command): Adjust and document conditions to reset dumpbase_ext. for gcc/testsuite/ChangeLog PR driver/96230 * gcc.misc-tests/outputs.exp: Add tests with -dumpbase-ext, with identical -dumpbase, with -dumpbase "", and without any -dumpbase.

2020-07-22c++: structural_comptypes additionNathan Sidwell1-9/+15
I had to debug structural_comptypes, and its complex if conditions and tail calling of same_type_p made that hard. I'd hope we can turn the eqivalent of return boolean_fn () ? true : false; into a tail call of the boolean. We also were not dealing with TYPEOF_TYPE. gcc/cp/ * typeck.c (structural_comptypes): [DECLTYPE_TYPE] break apart complex if. [UNDERLYING_TYPE]: Use an if. [TYPEOF_TYPE]: New.
2020-07-22c++: More cleanups for modern C++Nathan Sidwell3-58/+39
Here are some more places where we can declare variables at the assignment point, rather than use C89. Also, let's name our variables by what they contain -- the register allocator is perfectly able to track liveness for us. gcc/cp/ * decl.c (decls_match): Move variables into scopes they're needed in. (duplicate_decls): Use STRIP_TEMPLATE. (build_typename_type): Move var decls to their assignments. (begin_function_body): Likewise. * decl2.c (get_guard): Likewise. (mark_used): Use true for truthiness. * error.c (dump_aggr_type): Hold the decl in a var called 'decl', not 'name'.
2020-07-22c++: Shrink lambda-exprNathan Sidwell1-2/+2
I noticed the default capture mode and the discriminator both used ints. That seems excessive. This shrinks them to 8 bits and 16 bits respectively. I suppose the discriminator could use the remaining 24 bits of an int allocation unit, if we're worried about more that 64K lambdas per function. I know, users are strange :) On a 64 bit system this saves 64 bits, because we also had 32 bits of padding added. gcc/cp/ * cp-tree.h (struct tree_lambda_expr): Shrink default_capture_mode & discriminator.
