* Changes to support making the shift instructions be true BinaryOperators.Reid Spencer2007-02-021-35/+35
| | | | | | | | | | | | | This feature is needed in order to support shifts of more than 255 bits on large integer types. This changes the syntax for llvm assembly to make shl, ashr and lshr instructions look like a binary operator: shl i32 %X, 1 instead of shl i32 %X, i8 1 Additionally, this should help a few passes perform additional optimizations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33776 91177308-0d34-0410-b5e6-96231b3b80d8
* For PR950:Reid Spencer2006-12-231-47/+39
| | | | | | | | | This patch removes the SetCC instructions and replaces them with the ICmp and FCmp instructions. The SetCondInst instruction has been removed and been replaced with ICmpInst and FCmpInst. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@32751 91177308-0d34-0410-b5e6-96231b3b80d8

* For PR950:Reid Spencer2006-11-271-17/+52
| | | | | | | | | | | The long awaited CAST patch. This introduces 12 new instructions into LLVM to replace the cast instruction. Corresponding changes throughout LLVM are provided. This passes llvm-test, llvm/test, and SPEC CPUINT2000 with the exception of 175.vpr which fails only on a slight floating point output difference. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31931 91177308-0d34-0410-b5e6-96231b3b80d8
* For PR950:Reid Spencer2006-11-201-14/+16
| | | | | | | | | First in a series of patches to convert SetCondInst into ICmpInst and FCmpInst using only two opcodes and having the instructions contain their predicate value. Nothing uses these classes yet. More patches to follow. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31867 91177308-0d34-0410-b5e6-96231b3b80d8

* For PR950:Reid Spencer2006-11-081-12/+13
| | | | | | | | | This patch converts the old SHR instruction into two instructions, AShr (Arithmetic) and LShr (Logical). The Shr instructions now are not dependent on the sign of their operands. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31542 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | Replace the REM instruction with UREM, SREM and FREM. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31369 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | Make necessary changes to support DIV -> [SUF]Div. This changes llvm to have three division instructions: signed, unsigned, floating point. The bytecode and assembler are bacwards compatible, however. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31195 91177308-0d34-0410-b5e6-96231b3b80d8
