[x86] regenerate checks with update_llc_test_checks.py The dream of a unified check-line auto-generator for all phases of compilation is dead. The llc script has already diverged to be better at its goal, so having 2 scripts that do almost the same thing is just causing confusion. We can rip out the llc ability in update_test_checks.py next and rename it, so it will be clear that we have one script for llc check auto-generation and another for opt. llvm-svn: 305206

[x86, AVX] allow explicit calls to VZERO* to modify state in VZeroUpperInserter pass (PR27823) As noted in the review, there are still problems, so this doesn't the bug completely. Differential Revision: http://reviews.llvm.org/D20529 llvm-svn: 270718
2016-05-26 00:39:47 +08:00
; In the following 4 tests, the existing call to VZU/VZA ensures clean state before
; the call to the unknown, so we don't need to insert a second VZU at that point.
