* [PowerPC] Adjust the naming and operand order of fnmsub patternsJinsong Ji2019-10-031-1/+0
| | | | | | | | | | | | | | | | | | | | | | Summary: This is follow up patch of https://reviews.llvm.org/D67595. Adjust naming and the Commutable operands for additional patterns to make it easier to read. The testcase update also show that we can save some unecessary fmr as well.

* PowerPC: Do not use llc -march in tests.Matthias Braun2017-08-011-1/+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. This patch: - Removes -march if the .ll file already has a matching `target triple` directive or -mtriple argument. - In all other cases changes -march=ppc32/-march=ppc64 to -mtriple=ppc32--/-mtriple=ppc64-- See also the discussion in https://reviews.llvm.org/D35287 llvm-svn: 309754
* Adding -verify-machineinstrs option to PowerPC testsEhsan Amiri2016-08-031-2/+2
| | | | | | | | | | | Currently we have a number of tests that fail with -verify-machineinstrs. To detect this cases earlier we add the option to the testcases with the exception of tests that will currently fail with this option. PR 27456 keeps track of this failures. No code review, as discussed with Hal Finkel. llvm-svn: 277624
