dropped. This shrinks libllvmgcc.dylib another 67K git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28975 91177308-0d34-0410-b5e6-96231b3b80d8

2006-04-14Teach scalarrepl to promote unions of vectors and floats, producingChris Lattner
insert/extractelement operations. This implements Transforms/ScalarRepl/vector_promote.ll git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27710 91177308-0d34-0410-b5e6-96231b3b80d8
2006-03-08Fix a miscompilation of 188.ammp with the new CFE. 188.ammp is accessingChris Lattner
arrays out of range in a horrible way, but we shouldn't break it anyway. Details in the comments. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26606 91177308-0d34-0410-b5e6-96231b3b80d8

2005-12-14Fix Transforms/ScalarRepl/2005-12-14-UnionPromoteCrash.ll, a crash on undefinedChris Lattner
behavior in 126.gcc on big-endian systems. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24708 91177308-0d34-0410-b5e6-96231b3b80d8
2005-12-12Implement a little hack for parity with GCC on crafty. This speeds upChris Lattner
186.crafty by about 16% (from 15.109s to 13.045s) on my system. This turns allocas with unions/casts into scalars. For example crafty has something like this: union doub { unsigned short i[4]; long long d; }; int f(long long a) { return ((union doub){.d=a}).i[1]; } Instead of generating loads and stores to an alloca, we now promote the whole thing to a scalar long value. This implements: Transforms/ScalarRepl/AggregatePromote.ll git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24667 91177308-0d34-0410-b5e6-96231b3b80d8
2005-11-05Add support alignment of allocation instructions.Nate Begeman
Add support for specifying alignment and size of setjmp jmpbufs. No targets currently do anything with this information, nor is it presrved in the bytecode representation. That's coming up next. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24196 91177308-0d34-0410-b5e6-96231b3b80d8

2004-11-14Teach SROA how to promote an array index that is variable, if the dimensionChris Lattner
of the array is just two. This occurs 8 times in gcc, 6 times in crafty, and 12 times in 099.go. This implements ScalarRepl/sroa_two.ll git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17727 91177308-0d34-0410-b5e6-96231b3b80d8
