Patch contributed by Paolo Invernizzi. Thanks Paolo! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16368 91177308-0d34-0410-b5e6-96231b3b80d8
2004-07-20Fix a serious code pessimization problem. If an inlined function has a singleChris Lattner
return, clone the 'ret' BB code into the block AFTER the inlined call, not the other way around. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@15030 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-16Fix Inline/2004-04-15-InlineDeletesCall.llChris Lattner
Basically we were using SimplifyCFG as a huge sledgehammer for a simple optimization. Because simplifycfg does so many things, we can't use it for this purpose. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12977 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-13Fix compilation of 126.gcc: intrinsic functions cannot throw, so they are notChris Lattner
allowed in invoke instructions. Thus, if we are inlining a call to an intrinsic function into an invoke site, we don't need to turn the call into an invoke! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11384 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-08rename the "exceptional" destination of an invoke instruction to the ↵Chris Lattner
'unwind' dest git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11202 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-04Two changes:Chris Lattner
1. Don't scan to the end of alloca instructions in the caller function to insert inlined allocas, just insert at the top. This saves a lot of time inlining into functions with a lot of allocas. 2. Use splice to move the alloca instructions over, instead of remove/insert. This allows us to transfer a block at a time, and eliminates a bunch of silly symbol table manipulations. This speeds up the inliner on the testcase in PR209 from 1.73s -> 1.04s (67%) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11118 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-04Optimize the case where we are inlining a function that contains only one ↵Chris Lattner
basic block, and that basic block ends with a return instruction. In this case, we can just splice the cloned "body" of the function directly into the source basic block, avoiding a lot of rearrangement and splitBasicBlock's linear scan over the split block. This speeds up the inliner on the testcase in PR209 from 2.3s to 1.7s, a 35% reduction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11116 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-04More refactoring. Move alloca instructions and handle invoke instructionsChris Lattner
before we delete the original call site, allowing slight simplifications of code, but nothing exciting. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11109 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-04Move the cloning of the function body much earlier in the inlinefunctionChris Lattner
process. The only optimization we did so far is to avoid creating a PHI node, then immediately destroying it in the common case where the callee has one return statement. Instead, we just don't create the return value. This has no noticable performance impact, but paves the way for future improvements. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11108 91177308-0d34-0410-b5e6-96231b3b80d8

2003-10-27Get the list of PHI node values before the basic block is split. Also, addChris Lattner
PHI node entries for unwind instructions just like for call instructions which became invokes! This fixes PR57, tested by Inline/2003-10-26-InlineInvokeExceptionDestPhi.ll git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9526 91177308-0d34-0410-b5e6-96231b3b80d8

2003-10-14Do not move variable sized allocations to the top of the caller, which mightChris Lattner
break dominance relationships, and is otherwise bad. This fixes bug: Inline/2003-10-13-AllocaDominanceProblem.ll. This also fixes miscompilation of 3 176.gcc source files (reload1.c, global.c, flow.c) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9109 91177308-0d34-0410-b5e6-96231b3b80d8
2003-10-06Avoid doing pointless work. Amazingly, this makes us go faster.Chris Lattner
Running the inliner on 252.eon used to take 48.4763s, now it takes 14.4148s. In release mode, it went from taking 25.8741s to taking 11.5712s. This also fixes a FIXME. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8890 91177308-0d34-0410-b5e6-96231b3b80d8
