Scott Michel 48072bf179 - Expand tabs to spaces. 
- select_bits.ll now fully functional now that PR1993 is closed. It was
  previously broken by refactoring in SPUInstrInfo.td and using multiclasses.
- Same for eqv.ll

Scott Michel 944207423b This patch fixes a problem encountered by the CellSPU backend where variants 
were being pruned in patterns where a variable was used more than once, e.g.:

  (or (and R32C:$rA, R32C:$rC), (and R32C:$rB, (not R32C:$rC)))

In this example, $rC is used more than once and is actually significant to
instruction selection pattern matching when commuted variants are produced.
This patch scans the pattern's clauses and collects the variables, creating
a set of variables that are used more than once. TreePatternNode::isIsomorphicTo()
also understands that multiply-used variables are significant.

Chris Lattner 78e9cab229 Generalize FP constant shrinking optimization to apply to any vt 
except ppc long double.  This allows us to shrink constant pool
entries for x86 long double constants, which in turn allows us to
use flds/fldl instead of fldt.

 2008-03-05 06:48:13 +00:00

Dan Gohman da7897c4e1 Codegen support for i128 UINT_TO_FP. This just fixes a 
bug in r47928 (Int64Ty is the correct type for the constant
pool entry here) and removes the asserts, now that the code
is capable of handling i128.

 2008-03-05 02:07:31 +00:00
Evan Cheng 0a62cb44ce Add a target lowering hook to control whether it's worthwhile to compress fp constant. 
For x86, if sse2 is available, it's not a good idea since cvtss2sd is slower than a movsd load and it prevents load folding. On x87, it's important to shrink fp constant since fldt is very expensive.

Roman Levenstein c62c2bb4d0 Some improvements related to the computation of heights, depths of SUnits. 
The basic idea is that all these algorithms are computing the longest paths from the root node or to the exit node. Therefore the existing implementation that uses and iterative and potentially
exponential algorithm was changed to a well-known graph algorithm based on dynamic programming. It has a linear run-time.

  isn't incremented.

Bill Wendling 632ea65072 This is the initial check-in for adding register scavenging to PPC. (Currently, 
PPC-64 doesn't work.) This also lowers the spilling of the CR registers so that
it uses a register other than the default R0 register (the scavenger scrounges
for one). A significant part of this patch fixes how kill information is
handled.
