Sean Fertile	f65ec1bb1c	[PowerPC][NFC] We do not save/restore vrsave for any remaining subtargets. ... Extend lit test to show that we don't save or restore vrsave register when expanding @llvm.eh.unwind.init().	2020-02-20 10:20:33 -05:00
Ehsan Amiri	db43217a24	Adding -verify-machineinstrs option to PowerPC tests ... 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	2016-08-03 18:17:35 +00:00
Hal Finkel	055ca2ecc9	PPC: Ignore spill/restore requests for VRSAVE (except on Darwin) ... This fixes PR16418, which reports that a function calling __builtin_unwind_init() asserts. The cause is that this generates a spill/restore for VRSAVE, and we support that only on Darwin (because VRSAVE is only really used on Darwin). The test case checks only that we don't crash. We can add correctness checks once someone verifies what behavior the function is supposed to have. llvm-svn: 185235	2013-06-28 22:29:56 +00:00
