2010-06-26Implement rdar://7530813 - collapse multiple GEP instructions in IRgenChris Lattner
This avoids generating two gep's for common array operations. Before we would generate something like: %tmp = load i32* %X.addr ; <i32> [#uses=1] %arraydecay = getelementptr inbounds [100 x i32]* %A, i32 0, i32 0 ; <i32*> [#uses=1] %arrayidx = getelementptr inbounds i32* %arraydecay, i32 %tmp ; <i32*> [#uses=1] %tmp1 = load i32* %arrayidx ; <i32> [#uses=1] Now we generate: %tmp = load i32* %X.addr ; <i32> [#uses=1] %arrayidx = getelementptr inbounds [100 x i32]* %A, i32 0, i32 %tmp ; <i32*> [#uses=1] %tmp1 = load i32* %arrayidx ; <i32> [#uses=1] Less IR is better at -O0. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@106966 91177308-0d34-0410-b5e6-96231b3b80d8
2010-06-26Implement support for -fwrapv, rdar://7221421Chris Lattner
As part of this, pull together trapv handling into the same enum. This also add support for NSW multiplies. This also makes PCH disagreement on overflow behavior silent, since it really doesn't matter except for warnings and codegen (no macros get defined etc). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@106956 91177308-0d34-0410-b5e6-96231b3b80d8
2010-06-26implement rdar://7432000 - signed negate should codegen as NSW.Chris Lattner
While I'm in there, adjust pointer to member adjustments as well. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@106955 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-15Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.Daniel Dunbar
- This is designed to make it obvious that %clang_cc1 is a "test variable" which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it can be useful to redefine what gets run as 'clang -cc1' (for example, to set a default target). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91446 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-07add 'F' to a bunch of libm builtins so that codegen doesn't die on them,Chris Lattner
