constants to be rematerialized in PIC mode -- the extra indirection is a
complication.

regressions because CodeGen is currently not able to remat such loads.

large numbers of CBE regressions caused by r53958.

Store the predecessor MBB in the PHIUnion, rather than an index, since the indices will change after renumbering.

Fix a catastrophic PPC64 ABI bug: i32 operands which are passed in memory (all of the parameter registers are used) are loaded from sp offsets that were off by 4.

Rename instance variables, parameter argument names to eliminate a bunch of compilation warnings with -Wshadow.

to multiply the instruction count by a constant factor in a few places, which
caused the register allocator to require many more iterations.

This fixes several recent CBE regressions.

Added ConstantPool support.

This allows instructions like loads from global variables declared to
be constant to be moved out of loops."

Patch by Stefanus Du Toit!

llvm-svn: 53945

llvm-svn: 53943

Remove the GetResultInst instruction. It is still accepted in LLVM assembly
and bitcode, where it is now auto-upgraded to ExtractValueInst. Also, remove
support for return instructions with multiple values. These are auto-upgraded
to use InsertValueInst instructions.

The IRBuilder still accepts multiple-value returns, and auto-upgrades them
to InsertValueInst instructions.

Based on patch by Nicolas Capens.

Fix pr2566: incorrect assumption about bit_convert. It doesn't not have to output a vector value. Patch by Nicolas Capens!
