* Adding -verify-machineinstrs option to PowerPC testsEhsan Amiri2016-08-031-1/+1
| | | | | | | | | | | 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
* [PowerPC] Recurse through constants when looking for TLS globalsHal Finkel2015-10-281-0/+40
We cannot form ctr-based loops around function calls, including calls to __tls_get_addr used for PIC TLS variables. References to such TLS variables, however, might be buried within constant expressions, and so we need to search the entire constant expression to be sure that no references to such TLS variables exist. Fixes PR25256, reported by Eric Schweitz. This is a slightly-modified version of the patch suggested by Eric in the bug report, and a test case I created. llvm-svn: 251582
