[X86][AVX1] Regenerate checks and add i686 triple tests for folded logical ops llvm-svn: 302144

Add support for load folding of avx1 logical instructions AVX supports logical operations using an operand from memory. Unfortunately because integer operations were not added until AVX2 the AVX1 logical operation's types were preventing the isel from folding the loads. In a limited number of cases the peephole optimizer would fold the loads, but most were missed. This patch adds explicit patterns with appropriate casts in order for these loads to be folded. The included test cases run on reduced examples and disable the peephole optimizer to ensure the folds are being pattern matched.

Add support for load folding of avx1 logical instructions AVX supports logical operations using an operand from memory. Unfortunately because integer operations were not added until AVX2 the AVX1 logical operation's types were preventing the isel from folding the loads. In a limited number of cases the peephole optimizer would fold the loads, but most were missed. This patch adds explicit patterns with appropriate casts in order for these loads to be folded. The included test cases run on reduced examples and disable the peephole optimizer to ensure the folds are being pattern matched.

%tmp1 = bitcast float* %A to <8 x float>*
[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
