Evan Cheng 3276416fa4 Test case for fp logical instructions. 
llvm-svn: 56474
 2008-09-22 22:19:34 +00:00
Owen Anderson 97364655dc Significant improvements to the logic for merging live intervals. This code can't 
just use LI::MergeValueAsValue, as its behavior in the presence of overlapping ranges
isn't what StrongPHIElimination wants.

 2008-09-21 23:30:17 +00:00
Chris Lattner f1280cf744 Fold immediates into X86 shifts with fast isel. This generates: 
sarl    $3, %ecx

instead of:

movl    $3, %ecx
sarl    %cl, %edx

This shrinks fast isel 176.gcc by about 2000 instructions (.3%)

Dan Gohman ae9d9f4d3f Factor out code into HandleVirtRegDef, for consistency with 
Handle{Virt,Phys}Reg{Def,Use}. Remove a redundant check
for register zero, and redundant checks for isPhysicalRegister.

 2008-09-21 21:11:41 +00:00
Dan Gohman dfc19e6c01 Instead of building a list and sorting it just to find a maximum element, 
compute the maximum element directly.

Owen Anderson df8f1cb995 Fetch the starting index of the block when assigning intervals. This gets live-in indices 
correct in the presence of things like EH labels.

llvm-svn: 56410

Dan Gohman 9801ba451a Refactor X86SelectConstAddr, folding it into X86SelectAddress. This

GlobalValue stub loads.
