Alkis Evlogimenos 2debead504 Do not generate instructions with mismatched memory/immediate sized 
operands. The X86 backend doesn't handle them properly right now.

Chris Lattner b66f42427a The instruction combining pass removes dead instructions, there is no need 
to run the die pass after it.

Chris Lattner 51ea127bf3 Rename AddUsesToWorkList -> AddUsersToWorkList, as that is what it does. 
Create a new AddUsesToWorkList method
optimize memmove/set/cpy of zero bytes to a noop.

Misha Brukman 8a2c28fdda Right, it's really Extractor, not Extraction.

Misha Brukman 3151628a0d Add the prototype for the LoopExtractor Pass. 
llvm-svn: 11937
 2004-02-28 03:33:17 +00:00
Misha Brukman 03a11340ff A pass that uses the generic CodeExtractor to rip out *every* loop in every 
function, as long as the loop isn't the only one in that function. This should
help debugging passes easier with BugPoint.

Misha Brukman caa1a5abeb A generic code extractor: given a list of BasicBlocks, it will rip them out into 
a new function, taking care of inputs and outputs.

Alkis Evlogimenos 2dbc79df84 My previous commit broke the jit. The shift instructions always take 
an 8-bit immediate. So mark the shifts that take immediates as taking
an 8-bit argument. The rest with the implicit use of CL are marked
appropriately.

A bug still exists:

def SHLDmri32  : I2A8 <"shld", 0xA4, MRMDestMem>, TB;           // [mem32] <<= [mem32],R32 imm8

The immediate in the above instruction is 8-bit but the memory
reference is 32-bit. The printer prints this as an 8-bit reference
which confuses the assembler. Same with SHRDmri32.
