which is represented in codegen as an 'and' operation. This matches them
with movz instructions, instead of leaving them to be matched by and
instructions with an immediate field.

parallel its analogue, Value::value_use_iterator. The operator* method
now returns the user, rather than the use.

mmx needs its own fancy shuffle logic based on unpack; for now we get correct but awful code.

large numbers of CBE regressions caused by r53958.

llvm-svn: 53990

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.

llvm-svn: 53979

This fixes several recent CBE regressions.

llvm-svn: 53958

Added ConstantPool support.

llvm-svn: 53951

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.

generic SDNode's (nodes with their own constructors
should do sanity checking in the constructor).  Add
sanity checks for BUILD_VECTOR and fix all the places
that were producing bogus BUILD_VECTORs, as found by
"make check".  My favorite is the BUILD_VECTOR with
only two operands that was being used to build a
vector with four elements!

Use movaps instead of movups to spill 16-byte vector values when default alignment is >= 16. This fixes some massive performance regressions.
