2006-11-02For PR786:Reid Spencer
Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting fall out by removing unused variables. Remaining warnings have to do with unused functions (I didn't want to delete code without review) and unused variables in generated code. Maintainers should clean up the remaining issues when they see them. All changes pass DejaGnu tests and Olden. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31380 91177308-0d34-0410-b5e6-96231b3b80d8
2006-11-02General clean up of teh dwarf writer.Jim Laskey
1. Most significant is the folding of debug information entries. This reduced self hosted -g SelectionDAGISel.s from 120M to 13M and pretty close to matching .o file sizes with gcc. 2. Debug information entry printing for debugging the dwarf code. 3. Bring all the code closer to llvm standards. 4. Misc. fixes and doc clean ups. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31379 91177308-0d34-0410-b5e6-96231b3b80d8

2006-11-02Implement the getRegForInlineAsmConstraint method for PPC. With recentChris Lattner
sdisel changes, this eliminates a ton of copies around common inline asms. For example: int test2(int Y, int X) { asm("foo %0, %1" : "=r"(X): "r"(X)); return X; } now compiles to: _test2: foo r3, r4 blr instead of: _test2: mr r2, r4 foo r2, r2 mr r3, r2 blr GCC produces: _test2: foo r4, r4 mr r3,r4 blr git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31367 91177308-0d34-0410-b5e6-96231b3b80d8
2006-11-02Allow the getRegForInlineAsmConstraint method to return a register class withChris Lattner
no fixes physreg. Treat this as permission to use any register in the register class. When this happens and it is safe, allow the llvm register allcoator to allocate the register instead of doing it at isel time. This eliminates a ton of copies around common inline asms. For example: int test2(int Y, int X) { asm("foo %0, %1" : "=r"(X): "r"(X)); return X; } now compiles to: _test2: foo r3, r4 blr instead of: _test2: mr r2, r4 foo r2, r2 mr r3, r2 blr GCC produces: _test2: foo r4, r4 mr r3,r4 blr git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31366 91177308-0d34-0410-b5e6-96231b3b80d8
