2007-09-101. Don't call Value::getName(), which is slow.Chris Lattner
2. Lower calls to fabs and friends to FABS nodes etc unless the function has internal linkage. Before we wouldn't lower if it had a definition, which is incorrect. This allows us to compile: define double @fabs(double %f) { %tmp2 = tail call double @fabs( double %f ) ret double %tmp2 } into: _fabs: fabs f1, f1 blr git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41805 91177308-0d34-0410-b5e6-96231b3b80d8

2007-09-10It's not safe to rematerialize MOV32r0 etc. by simply cloning the originalEvan Cheng

Use APFloat in UpgradeParser and AsmParser. Change all references to ConstantFP to use the APFloat interface rather than double. Remove the ConstantFP double interfaces.

2007-09-05Due to label merging, the last label for an invokeDuncan Sands
may be the same as the first label for the following invoke. Remove a micro-optimization which was wrong in this case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41720 91177308-0d34-0410-b5e6-96231b3b80d8
2007-09-05Fix PR1628. When exception handling is turned on,Duncan Sands
labels are generated bracketing each call (not just invokes). This is used to generate entries in the exception table required by the C++ personality. However it gets in the way of tail-merging. This patch solves the problem by no longer placing labels around ordinary calls. Instead we generate entries in the exception table that cover every instruction in the function that wasn't covered by an invoke range (the range given by the labels around the invoke). As an optimization, such entries are only generated for parts of the function that contain a call, since for the moment those are the only instructions that can throw an exception [1]. As a happy consequence, we now get a smaller exception table, since the same region can cover many calls. While there, I also implemented folding of invoke ranges - successive ranges are merged when safe to do so. Finally, if a selector contains only a cleanup, there's a special shorthand for it - place a 0 in the call-site entry. I implemented this while there. As a result, the exception table output (excluding filters) is now optimal - it cannot be made smaller [2]. The problem with throw filters is that folding them optimally is hard, and the benefit of folding them is minimal. [1] I tested that having trapping instructions (eg divide by zero) in such a region doesn't cause trouble. [2] It could be made smaller with the help of higher layers, eg by having branch folding reorder basic blocks ending in invokes with the same landing pad so they follow each other. I don't know if this is worth doing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41718 91177308-0d34-0410-b5e6-96231b3b80d8
