John Criswell 970af11af8 Move some constant folding functions into LLVMAnalysis since they are used 
by Analysis and Transformation passes.

John Criswell fe5f33b120 Move some constant folding code shared by Analysis and Transform passes 
into the LLVMAnalysis library.
This allows LLVMTranform and LLVMTransformUtils to be archives and linked
with LLVMAnalysis.a, which provides any missing definitions.

Chris Lattner 0fe7551bc0 Teach instcombine to promote stuff like (cast (malloc sbyte, 8*X) to int*) 
into: malloc int, (2*X)

Chris Lattner b3ecf96900 Promote cases like cast (malloc sbyte, 100) to int* into 
(malloc [25 x int]) directly without having to convert to
(malloc [100 x sbyte]) first.

Chris Lattner 6d92ce7be7 Make sure to build things in the right order, build with the .o file, not the 
.a file to unbreak the build after john's change

John Criswell 94b7bea733 1. Remove libraries no longer created from the list of libraries linked into the 
SparcV9 JIT.
2. Make LLVMTransformUtils a relinked object file and always link it before
   LLVMAnalysis.a.  These two libraries have circular dependencies on each
   other which creates problem when building the SparcV9 JIT.  This change
   fixes the dependency on all platforms problems with a minimum of fuss.

Chris Lattner ce9580fce4 Add nodes for CondCodeSDNode and setcc, and add a bunch of pattern fragments 
to make it easy to use them.  This lets you write patterns like:

(set PRRC:$rd, (setne GPRC:$rS, imm:$SH))

and stuff.

Nate Begeman b2f9801555 Add a regression test for the recent fix for FP_TO_UINT lowering in the ppc 
backend.

llvm-svn: 23995
 2005-10-25 23:53:21 +00:00
Nate Begeman ff1796534f Add a note about some bitfield stuff we could be doing better. 
llvm-svn: 23994
 2005-10-25 23:50:02 +00:00
Nate Begeman 762bf809b5 Correctly Expand or Promote FP_TO_UINT based on the capabilities of the 
machine.  This allows us to generate great code for i32 FP_TO_UINT now on
targets with 64 bit extensions.

llvm-svn: 23993
 2005-10-25 23:48:36 +00:00
Nate Begeman d8f2a1a0f3 Allow custom lowered FP_TO_SINT ops in the check for whether a larger 
FP_TO_SINT is preferred to a larger FP_TO_UINT.  This seems to be begging
for a TLI.isOperationCustom() helper function.
