* While hunting for two hanging tests,Gabor Greif2008-02-262-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | (on solaris10, which are: CodeGen/PowerPC/frounds.ll Transforms/InstCombine/2008-02-23-MulSub.ll) I needed a tool to figure out which one is the guilty. To this end I have added a verbosity option to the test/Makefile. It can be invoked thus: gmake check TESTSUITE=CodeGen/PowerPC VERBOSE="-v -v" (The number of "-v"s specifies the verbosity level. Instead of "-v" other aliases can be specified, please consult the dejagnu docs for info.) At level >= 2 following line is logged for each test, before running it: ABOUT TO RUN: <test>.ll git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47602 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix a nasty bug in LegalizeTypes (spotted inDuncan Sands2008-02-266-60/+70
| | | | | | | | | | | | | | | | | | CodeGen/PowerPC/illegal-element-type.ll): suppose a node X is processed, and processing maps it to a node Y. Then X continues to exist in the DAG, but with no users. While processing some other node, a new node may be created that happens to be equal to X, and thus X will be reused rather than a truly new node. This can cause X to "magically reappear", and since it is in the Processed state in will not be reprocessed, so at the end of type legalization the illegal node X can still be present. The solution is to replace X with Y whenever X gets resurrected like this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47601 91177308-0d34-0410-b5e6-96231b3b80d8

* Add support for intermodule tail calls on x86/32bit withArnold Schwaighofer2008-02-261-12/+24
| | | | | | | | | GOT-style position independent code. Before only tail calls to protected/hidden functions within the same module were optimized. Now all function calls are tail call optimized. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47594 91177308-0d34-0410-b5e6-96231b3b80d8
* Change the lowering of arguments for tail call optimizedArnold Schwaighofer2008-02-262-42/+84
| | | | | | | | | | | | | calls. Before arguments that could overwrite each other were explicitly lowered to a stack slot, not giving the register allocator a chance to optimize. Now a sequence of copyto/copyfrom virtual registers ensures that arguments are loaded in (virtual) registers before they are lowered to the stack slot (and might overwrite each other). Also parameter stack slots are marked mutable for (potentially) tail calling functions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47593 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix isNegatibleForFree to not return true for ConstantFP nodes Chris Lattner2008-02-262-33/+61
| | | | | | | | | | after legalize. Just because a constant is legal (e.g. 0.0 in SSE) doesn't mean that its negated value is legal (-0.0). We could make this stronger by checking to see if the negated constant is actually legal post negation, but it doesn't seem like a big deal. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47591 91177308-0d34-0410-b5e6-96231b3b80d8
