2012-02-03Revert "Disable InstCombine unsafe folding bitcasts of calls w/ varargs."Jim Grosbach
This reverts commit d0e277d272d517ca1cda368267d199f0da7cad95. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149647 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-01Disable InstCombine unsafe folding bitcasts of calls w/ varargs.Jim Grosbach
Changing arguments from being passed as fixed to varargs is unsafe, as the ABI may require they be handled differently (stack vs. register, for example). Remove two tests which rely on the bitcast being folded into the direct call, which is exactly the transformation that's unsafe. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149457 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-17manually upgrade a bunch of tests to modern syntax, and remove some thatChris Lattner
are either unreduced or only test old syntax. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133228 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-11Change tests from "opt %s" to "opt < %s" so that opt doesn't see theDan Gohman
input filename so that opt doesn't print the input filename in the output so that grep lines in the tests don't unintentionally match strings in the input filename. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81537 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-08Use opt -S instead of piping bitcode output through llvm-dis.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81257 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-08Change these tests to feed the assembly files to opt directly, insteadDan Gohman
of using llvm-as, now that opt supports this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81226 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-07Don't depend on Tcl behavior of redirecting stderr for all commands in aDaniel Dunbar
pipeline. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81153 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-10Ignore stderr for some more tests that expect warnings there.Matthijs Kooijman
This fixes 2 testcases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52184 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-13When turning a call to a bitcast function into a direct call,Duncan Sands
if this becomes a varargs call then deal correctly with any parameter attributes on the newly vararg call arguments. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45931 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-06The transform that tries to turn calls to bitcast functions intoDuncan Sands
direct calls bails out unless caller and callee have essentially equivalent parameter attributes. This is illogical - the callee's attributes should be of no relevance here. Rework the logic, which incidentally fixes a crash when removed arguments have attributes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45658 91177308-0d34-0410-b5e6-96231b3b80d8
