2020-07-27gcc.dg/tree-ssa/vector-4.c: Adjust for mmix.Hans-Peter Nilsson1-1/+2
Again, the variables are "privatized" using ASM_PN_FORMAT for MMIX (but apparently not for other targets) and the line to match looks like: D.1427 = VEC_PERM_EXPR <a::0, b::1, { 0, 4, 1, 5 }>; gcc/testsuite: * gcc.dg/tree-ssa/vector-4.c: Adjust for mmix.

2020-07-27gcc.dg/tree-ssa/ssa-dom-cse-2.c: xfail scan for mmix.Hans-Peter Nilsson1-1/+1
Looking at the dump and the test, I guess all "64-bit targets" fail the test for the reasons seen in the comment just above the dg-final, whose last two lines make it to the patch context. Maybe the xfail target list can be shortened by removing most targets and use just "lp64". That doesn't cover it passing on x86_64 and s390x-zarch though. gcc/testsuite: * gcc.dg/tree-ssa/ssa-dom-cse-2.c: xfail scan for mmix.

2020-07-27gcc.dg/tree-ssa/reassoc-20.c: Adjust for mmix.Hans-Peter Nilsson1-1/+1
The expression of interest looks like "e_5 = a::0_1 + b::1_2;" for mmix-knuth-mmixware, while other targets have a "." instead of the "::". ISTM the most useful change here is not to disable the test, but to add an optional character in the matched expression to match the "extra" ":". Also checked cris-elf to assert that the expression still passes for an "ordinary" ELF target. gcc/testsuite: * gcc.dg/tree-ssa/reassoc-20.c: Adjust for mmix.
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.

This enables types __int128 et al for move, add, subtract, and logical operations. At least shift, rotate, multiple, divide, and modulus are broken so we can expect some test failures. This is required now because libgomp no longer builds without __int128.

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.
