[X86] Autogenerate complete checks. NFC
2020-05-30 13:46:57 +08:00
; NOTE: Assertions have been autogenerated by utils/update_llc_test_checks.py
Fixed a bug in narrowing store operation. Type MVT::i1 became legal in KNL, but store operation can't be narrowed to this type, since the size of VT (1 bit) is not equal to its actual store size(8 bits). Added a test provided by David (dag@cray.com) llvm-svn: 226805

[opaque pointer type] Add textual IR support for explicit type parameter to load instruction Essentially the same as the GEP change in r230786. A similar migration script can be used to update test cases, though a few more test case improvements/changes were required this time around: (r229269-r229278) import fileinput import sys import re pat = re.compile(r"((?:=|:|^)\s*load (?:atomic )?(?:volatile )?(.*?))(| addrspace\(\d+\) *)\*($| *(?:%|@|null|undef|blockaddress|getelementptr|addrspacecast|bitcast|inttoptr|\[\[[a-zA-Z]|\{\{).*$)") for line in sys.stdin: sys.stdout.write(re.sub(pat, r"\1, \2\3*\4", line)) Reviewers: rafael, dexonsmith, grosser Differential Revision: http://reviews.llvm.org/D7649 llvm-svn: 230794
