2010-01-27Eliminate target hook IsEligibleForTailCallOptimization.Evan Cheng
Target independent isel should always pass along the "tail call" property. Change target hook LowerCall's parameter "isTailCall" into a refernce. If the target decides it's impossible to honor the tail call request, it should set isTailCall to false to make target independent isel happy. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94626 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-26use EmitLinkage for functions as well as globals. One outputChris Lattner
change is that we now use ".linkonce discard" for global variables instead of ".linkonce samesize". These should be the same, just less strict. If anyone is interested in mcizing MCSection for COFF targets, this should be easy to fix. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94623 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94616 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-26Fix inline cost predictions with SCIENCE.Jakob Stoklund Olesen
After running a batch of measurements, it is clear that the inliner metrics need some adjustments: Own argument bonus: 20 -> 5 Outgoing argument penalty: 0 -> 5 Alloca bonus: 10 -> 5 Constant instr bonus: 7 -> 5 Dead successor bonus: 40 -> 5*(avg instrs/block) The new cost metrics are generaly 25 points higher than before, so we may need to move thresholds. With this change, InlineConstants::CallPenalty becomes a political correction: if (!isa<IntrinsicInst>(II) && !callIsSmall(CS.getCalledFunction())) NumInsts += InlineConstants::CallPenalty + CS.arg_size(); The code size is accurately modelled by CS.arg_size(). CallPenalty is added because calls tend to take a long time, so it may not be worth it to inline a function with lots of calls. All of the political corrections are in the InlineConstants namespace: IndirectCallBonus, CallPenalty, LastCallToStaticBonus, ColdccPenalty, NoreturnPenalty. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94615 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-26now that enough stuff is constified, move function header printingChris Lattner
logic up from X86 into the common code. The other targets will hopefully start using this soon. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94614 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-26Revert test polarity to match comment and desired outcome. Remove undeserved ↵Jakob Stoklund Olesen
bonus. A GEP with all constant indices is already considered free by analyzeBasicBlock(), so don't give it an extra bonus in CountCodeReductionForAlloca(). This patch should remove a small positive bias toward inlining functions with variable-index GEPs, and remove a smaller negative bias from functions with all-constant index GEPs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94591 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-26Remove dead code.Jakob Stoklund Olesen
Functions containing indirectbr are marked NeverInline by analyzeBasicBlock(), so there is no point in giving indirectbr special treatment in CountCodeReductionForConstant. It is never called. No functional change intended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94590 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-26Eliminate SetDirective, and replace it with HasSetDirective.Chris Lattner
Default HasSetDirective to true, since most targets have it. The targets that claim to not have it probably do, or it is spelled differently. These include Blackfin, Mips, Alpha, and PIC16. All of these except pic16 are normal ELF targets, so they almost certainly have it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94585 91177308-0d34-0410-b5e6-96231b3b80d8
