2006-11-15Remove the isTwoAddress property from the CodeGenInstruction class. It shouldChris Lattner
not be used for anything other than backwards compat constraint handling. Add support for a new DisableEncoding property which contains a list of registers that should not be encoded by the generated code emitter. Convert the codeemitter generator to use this, fixing some PPC JIT regressions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31769 91177308-0d34-0410-b5e6-96231b3b80d8

2004-08-10This was a good idea, but until this does not break the build ofChris Lattner

2003-08-05The CodeEmitterGenerator used to consider ANY uninitialized field as being anChris Lattner
operand (unless it's annul or predict). Now we only consider fields to be operands if they are uninitialized AND used in the "Inst" field. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7589 91177308-0d34-0410-b5e6-96231b3b80d8

2003-07-18Added a DEBUG() guard to a debug information printout.Misha Brukman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7203 91177308-0d34-0410-b5e6-96231b3b80d8
2003-07-15Fixed a bug: outputting name of variable instead of its value.Misha Brukman
Also, placed DEBUG() guards around debug information so that the generated file is much smaller and hence should be faster to preprocess/compile. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7180 91177308-0d34-0410-b5e6-96231b3b80d8
2003-07-15This optimization greatly enhances efficiency of creating new instructions byMisha Brukman
masking and shifting operands directly into their place in the instruction, instead of the old-fashioned way of ORing in each bit separately. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7179 91177308-0d34-0410-b5e6-96231b3b80d8
2003-07-07Stop using the `Offset' variable, as we are cycling through the bits of a fieldMisha Brukman
initializer and the loop index variable already carries the offset information that we need. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7123 91177308-0d34-0410-b5e6-96231b3b80d8

2003-06-06All debug print statements are now output with the DEBUG() guard to makeMisha Brukman
output clean so that tests can automatically diff the output. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6643 91177308-0d34-0410-b5e6-96231b3b80d8

* Added comment as to why we are still ignoring predict and annul bits. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6636 91177308-0d34-0410-b5e6-96231b3b80d8
