Evan Cheng f4b5d491df Added DAG xforms. e.g. 
(vextract (v4f32 s2v (f32 load $addr)), 0) -> (f32 load $addr) 
(vextract (v4i32 bc (v4f32 s2v (f32 load $addr))), 0) -> (i32 load $addr)
Remove x86 specific patterns.

Dale Johannesen f864ac96d8 Next powerpc long double bits. Comparisons work, 
although not well, and shortening FP converts.

 2007-10-06 00:43:45 +00:00
Neil Booth 0ea72a9a91 Generalize tcFullMultiply so that the operands can be of differing 
part widths.  Also, return the number of parts actually required to
hold the result's value.
Remove an over-cautious condition from rounding of float->hex conversion.

Gordon Henriksen 7330acdec7 Removing the silly CHelpers header by rolling wrap and unwrap into the C 
bindings headers themselves, hidden behind #ifdef __cplusplus.

Evan Cheng d3ccf00870 INC64_32r -> LEA64_32r is better than INC64_32r -> LEA32r, but it still can 
cause performance degradation.

Evan Cheng fa2c828687 In 64-bit mode, avoid using leal with 32-bit 32-bit address size, e.g. 
leal 1(%ecx), %edi, which requires 67H prefix.

Dale Johannesen c0154c06d6 First round of ppc long double. call/return and 
basic arithmetic works.
Rename RTLIB long double functions to distinguish
different flavors of long double; the lib functions
have different names, alas.

Evan Cheng 991cf47221 Oops. Didn't mean to leave this in.

 2007-10-05 01:39:40 +00:00
Evan Cheng 79e9713b11 If a node that defines a physical register that is expensive to copy. The 
scheduler will try a number of tricks in order to avoid generating the
copies. This may not be possible in case the node produces a chain value
that prevent movement. Try unfolding the load from the node before to allow
it to be moved / cloned.
