Jim Laskey 48850c10c0 This is a general clean up of the PowerPC ABI. Address several problems and 
bugs including making sure that the TOS links back to the previous frame,
that the maximum call frame size is not included twice when using frame
pointers, no longer growing the frame on calls, double storing of SP and
a cleaner/faster dynamic alloca.

Bill Wendling c7969fd1e7 Added a new method "CreateNewLiveInterval" which, given a list of 
LiveRanges, creates a new LiveInterval from them. The LiveRanges should
have existed already in another LiveInterval, but removed.

Chris Lattner 5771156be0 Stop using isTwoAddress, switching to operand constraints instead. 
Tell the codegen emitter that specific operands are not to be encoded, fixing
JIT regressions w.r.t. pre-inc loads and stores (e.g. lwzu, which we generate
even when general preinc loads are not enabled).

llvm-svn: 31770
 2006-11-15 23:24:18 +00:00
Chris Lattner 78a403f90e Remove the isTwoAddress property from the CodeGenInstruction class. It should 
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.

Chris Lattner 1396961e85 Switch loads over to use memri as the operand instead of a reg/imm operand 
pair for cleanliness.  Add instructions for PPC32 preinc-stores with commented
out patterns.  More improvement is needed to enable the patterns, but we're
getting close.
