* [PowerPC] Enable splat generation for BUILD_VECTOR with little endianBill Schmidt2015-04-031-4/+2
| | | | | | | | | | | | | | | | | | | When enabling PPC64LE, I disabled some optimizations of BUILD_VECTOR nodes for little endian because wrong results were produced. I've subsequently investigated and found this is due to a call to BuildVectorSDNode::isConstantSplat that was always specifying big-endian. With this changed to correctly identify the target endianness, the optimizations work as expected. I found another case of a call to the same method with big-endian hardcoded, in PPC::isAllNegativeZeroVector(). I discovered this was an orphaned method with no callers, so I've just removed it. The existing test/CodeGen/PowerPC/vec_constants.ll checks these optimizations, so for testing I've just added a variant for little endian. llvm-svn: 234011
* [opaque pointer type] Add textual IR support for explicit type parameter to ↵David Blaikie2015-02-271-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | 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
* Convert CodeGen/*/*.ll tests to use the new CHECK-LABEL for easier ↵Stephen Lin2013-07-131-8/+8
| | | | | | | | | | debugging. No functionality change and all tests pass after conversion. This was done with the following sed invocation to catch label lines demarking function boundaries: sed -i '' "s/^;\( *\)\([A-Z0-9_]*\):\( *\)test\([A-Za-z0-9_-]*\):\( *\)$/;\1\2-LABEL:\3test\4:\5/g" test/CodeGen/*/*.ll which was written conservatively to avoid false positives rather than false negatives. I scanned through all the changes and everything looks correct. llvm-svn: 186258

* Additional fixes for bug 15155.Bill Schmidt2013-02-201-1/+0
| | | | | | | | This handles the cases where the 6-bit splat element is odd, converting to a three-instruction sequence to add or subtract two splats. With this fix, the XFAIL in test/CodeGen/PowerPC/vec_constants.ll is removed. llvm-svn: 175663
* Disable a couple more vector splat optimizations on PPC.Benjamin Kramer2013-02-041-1/+41
| | | | | | | I didn't see those because the test case used "not grep". FileCheck the test and XFAIL it, preserving the old optimization, so this can be fixed eventually. llvm-svn: 174330

* For PR1319:Reid Spencer2007-04-161-1/+0
| | | | | | | | Remove && from the end of the lines to prevent tests from throwing run lines into the background. Also, clean up places where the same command is run multiple times by using a temporary file. llvm-svn: 36142
