| | | | | | | | | 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

| | | | | | | | 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

* Two changes:Chris Lattner2004-02-041-5/+12
| | | | | | | | | | | | | | 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
* Optimize the case where we are inlining a function that contains only one ↵Chris Lattner2004-02-041-37/+67
| | | | | | | | | | | | 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

| | | | | | | | 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
* Move the cloning of the function body much earlier in the inlinefunctionChris Lattner2004-02-041-52/+54
| | | | | | | | | | | 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
