Reid Spencer cec21a5592 Dump the old va_arg and va_next upgrade support. No need to keep track of 
the current basic block any more either.

 2006-12-05 23:28:06 +00:00
Reid Spencer 0646eb415d Finally get the casting right in this file. Also, remove some unnecessary 
casting because sdiv doesn't require operand signs to match any more.

Chris Lattner c20b7e878a If we have ScalarSSE, we can select bitconvert into single instructions. 
This compiles bitcast.ll:test3/test4 into:

_test3:

        ret
_test4:
        movd %edi, %xmm0
        ret

 2006-12-05 07:29:55 +00:00
Reid Spencer a16f930aac Can't make these fail now with just BitCast. Previous failures must have 
been in conjunction with something else. By right, they should just be
BitCasts.

llvm-svn: 32218
 2006-12-05 06:43:58 +00:00
Evan Cheng 62cdc3f011 - Fix X86-64 JIT by temporarily disabling code that treats GV address as 32-bit 
immediate in small code model. The JIT cannot ensure GV's are placed in the
lower 4G.
- Some preliminary support for large code model.

 2006-12-04 02:46:44 +00:00
Reid Spencer c4dacf2455 Take a baby step towards getting rid of inferred casts. Provide methods on 
CastInst and ConstantExpr that allow the signedness to be explicitly passed
in and reliance on signedness removed from getCastOpcode. These are
temporary measures useful during the conversion of inferred casts.
