* 1. Add load/store words from the stackReed Kotler2012-09-283-34/+86
| | | | | | | | | | | 2. As part of this, added assembly format FEXT_RI16_SP_explicit_ins and moved other lines for FEXT_RI16 formats to be in the right place in the code. 3. Added mayLoad and mayStore assignements for the load/store instructions added and for ones already there that did not have this assignment. 4. Another patch will deal with the problem of load/store byte/halfword to the stack. This is a particular Mips16 problem. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@164811 91177308-0d34-0410-b5e6-96231b3b80d8
* Remove <def,read-undef> flags from partial redefinitions.Jakob Stoklund Olesen2012-09-271-0/+6
| | | | | | | | | The new coalescer can turn a full virtual register definition into a partial redef by merging another value into an unused vector lane.

| | | | | | | | If the width is very large it gets truncated from uint64_t to uint32_t when passed to TD->fitsInLegalInteger. The truncated value can fit in a register.

Granted there is exactly one case where that it will ever do anything, but there's no reason to skip it. For reference, that case is a subtraction between two constant offsets on the same global variable, eg., "&A[123] - &A[4].f". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@164760 91177308-0d34-0410-b5e6-96231b3b80d8
