20e105f4b1 Fixed a bug with pervious ColorCallArg 
llvm-svn: 1278
 2001-11-12 20:54:19 +00:00

24e29431bc Canged ColorCallArg so that when a call arg is directly pushed on to stack 
for argument passing, that instruction is directly added to the InstructionsBefore
set of the called machine instruction - i.e., it is not reordered.

f889a11590 Fix bugs in FITOS/D instruction generation. 
The space for optional args in the stack frame is now being computed,
so finish the code generation for the variable `alloca'.
Finally, made a major overhaul of how stack frame is managed.

ea5d1f5db8 Fixed instruction information for RDCCR and WRCCR. 
Fixed selection to create a TmpInstruction for each integer CC register
(since it is an implicit side-effect, unlike FP CC registers which are
explicit operands).
