be listed second as that is how the instructions are usually created (and is the correct asm syntax) so that it's assembled correctly from its constituents git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17183 91177308-0d34-0410-b5e6-96231b3b80d8
2004-10-23Fix the SPR field for MTLR, MFLR, MTCTR, and MFCTR instructions.Misha Brukman
The decimal value given in the manual (8 or 9) really needs to be multiplied by a factor of 32 because of the group of 5 zero bits after the register code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17182 91177308-0d34-0410-b5e6-96231b3b80d8

2004-10-23Kill casts from integer types to unsigned byte, when the cast was only usedNate Begeman
as the shift amount operand to a shift instruction. This was causing us to emit unnecessary clear operations for code such as: int foo(int x) { return 1 << x; } git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17175 91177308-0d34-0410-b5e6-96231b3b80d8

2004-10-20Small performance improvement in generated C code:John Criswell
Instead of unconditionally copying all phi node values into temporaries for all successor blocks, generate code that will determine what successor block will be called and then copy only those phi node values needed by the successor block. This seems to cut down namd execution time from being 8% higher than GCC to 4% higher than GCC. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17144 91177308-0d34-0410-b5e6-96231b3b80d8

2004-10-18Initial implementation of the strength reduction for GEP instructions inNate Begeman
loops. This optimization is not turned on by default yet, but may be run with the opt tool's -loop-reduce flag. There are many FIXMEs listed in the code that will make it far more applicable to a wide range of code, but you have to start somewhere :) This limited version currently triggers on the following tests in the MultiSource directory: pcompress2: 7 times cfrac: 5 times anagram: 2 times ks: 6 times yacr2: 2 times git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17134 91177308-0d34-0410-b5e6-96231b3b80d8
