* [Codegen][X86] Modernize/regenerate old tests. NFCI.Dávid Bolvanský2019-12-101-1/+17
| | | | | | | | | | | | | | | | Summary: Switch to FileCheck where possible. Adjust tests so they can be easily regenerated by update scripts.

* X86: Do not use llc -march in tests.Matthias Braun2017-08-021-1/+1
| | | | | | | | | | | | | | | `llc -march` is problematic because it only switches the target architecture, but leaves the operating system unchanged. This occasionally leads to indeterministic tests because the OS from LLVM_DEFAULT_TARGET_TRIPLE is used. However we can simply always use `llc -mtriple` instead. This changes all the tests to do this to avoid people using -march when they copy and paste parts of tests. See also the discussion in https://reviews.llvm.org/D35287 llvm-svn: 309774
* Flip the new block-placement pass to be on by default.Chandler Carruth2012-04-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | This is mostly to test the waters. I'd like to get results from FNT build bots and other bots running on non-x86 platforms. This feature has been pretty heavily tested over the last few months by me, and it fixes several of the execution time regressions caused by the inlining work by preventing inlining decisions from radically impacting block layout. I've seen very large improvements in yacr2 and ackermann benchmarks, along with the expected noise across all of the benchmark suite whenever code layout changes. I've analyzed all of the regressions and fixed them, or found them to be impossible to fix. See my email to llvmdev for more details. I'd like for this to be in 3.1 as it complements the inliner changes, but if any failures are showing up or anyone has concerns, it is just a flag flip and so can be easily turned off. I'm switching it on tonight to try and get at least one run through various folks' performance suites in case SPEC or something else has serious issues with it. I'll watch bots and revert if anything shows up. llvm-svn: 154816

ffastmath mode. This fixes rdar://5902801, a miscompilation of gcc.dg/builtins-8.c. Bill, please pull this into Tak. llvm-svn: 50523
