Eliminate more uses of llvm-as and llvm-dis. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81290 91177308-0d34-0410-b5e6-96231b3b80d8 2009-09-08 23:54:48 +00:00			`; RUN: llc < %s -march=x86-64 -relocation-model=pic > %t`
Fix the remaining TCL-style quotes found in the testsuite. This is another mechanical change accomplished though the power of terrible Perl scripts. I have manually switched some "s to 's to make escaping simpler. While I started this to fix tests that aren't run in all configurations, the massive number of tests is due to a really frustrating fragility of our testing infrastructure: things like 'grep -v', 'not grep', and 'expected failures' can mask broken tests all too easily. Essentially, I'm deeply disturbed that I can change the testsuite so radically without causing any change in results for most platforms. =/ git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159547 91177308-0d34-0410-b5e6-96231b3b80d8 2012-07-02 19:09:46 +00:00			`; RUN: grep "movswl %ax, %edi" %t`

Revert 67132. This is breaking some objective-c apps. Also fixes SDISel so it does not force promote return value if the function is not marked signext / zeroext. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@67701 91177308-0d34-0410-b5e6-96231b3b80d8 2009-03-25 20:20:11 +00:00			`; XFAIL: *`
Don't force promotion of return arguments on the callee. Some architectures (like x86) don't require it. This fixes bug 3779. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@67132 91177308-0d34-0410-b5e6-96231b3b80d8 2009-03-17 23:43:59 +00:00
