* [opaque pointer type] Add textual IR support for explicit type parameter to ↵David Blaikie2015-02-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | 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
* X86: Don't emit conditional floating point moves on when targeting ↵Benjamin Kramer2012-04-271-0/+12
pre-pentiumpro architectures. * Model FPSW (the FPU status word) as a register. * Add ISel patterns for the FUCOM*, FNSTSW and SAHF instructions. * During Legalize/Lowering, build a node sequence to transfer the comparison result from FPSW into EFLAGS. If you're wondering about the right-shift: That's an implicit sub-register extraction (%ax -> %ah) which is handled later on by the instruction selector. Fixes PR6679.
