Devang Patel cbbf291f34 Keep track of analysis information inherited from Module pass manager.

Scott Michel bbaf3edace Add more patterns to match in the integer comparison test harnesses. 
Fix bugs encountered, mostly due to range matching for immediates;
the CellSPU's 10-bit immediates are sign extended, covering a
larger range of unsigned values.

llvm-svn: 48523
 2008-03-19 01:11:35 +00:00
Evan Cheng 44c0b4f754 Fix live variables issues: 
1. If part of a register is re-defined, an implicit kill and an implicit def are added to denote read / mod / write. However, this should only be necessary if the register is actually read later. This is a performance issue.
2. If a sub-register is being defined, and it doesn't have a previous use, do not add a implicit kill to the last use of a super-register:
   = EAX, AX<imp-use,kill>
...
AX =
In this case, EAX is live but AX is killed, this is wrong and will cause the coalescer to do bad things.

Scott Michel 4799ea70ea Note that gcc 4.0.1 will trip internal LLVM asserts (e.g., pred_iterator) if compiling

Chris Lattner 7d4152bda6 Check in some #ifdef'd out code switching call argument 
lowering over to SparcCallingConv.td.  We can't make the switch
yet because we can't say to pass f64 registers in 2 x i32 registers
with the td file yet.

Chris Lattner 49b269d780 Start moving sparc to use SparcCallingConv.td, switching over

of i64 values were returned in the wrong registers before.

llvm-svn: 48443
 2008-03-17 05:41:48 +00:00
