* This increases the maximum for MVT::LAST_VALUETYPEDavid Greene2009-06-243-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | This change doubles the allowable value for MVT::LAST_VALUETYPE. It does this by doing several things. 1. Introduces MVT::MAX_ALLOWED_LAST_VALUETYPE which in this change has a value of 64. This value contains the current maximum for the MVT::LAST_VALUETYPE. 2. Instead of checking "MVT::LAST_VALUETYPE <= 32", all of those uses now become "MVT::LAST_VALUETYPE <= MVT::MAX_ALLOWED_LAST_VALUETYPE" 3. Changes the dimension of the ValueTypeActions from 2 elements to four elements and adds comments ahead of the declaration indicating the it is "(MVT::MAX_ALLOWED_LAST_VALUETYPE/32) * 2". This at least lets us find what is affected if and when MVT::MAX_ALLOWED_LAST_VALUETYPE gets changed. 4. Adds initializers for the new elements of ValueTypeActions. This does NOT add any types in MVT. That would be done separately. This doubles the size of ValueTypeActions from 64 bits to 128 bits and gives us the freedom to add more types for AVX. llvm-svn: 74110

* - Update register allocation hint after coalescing. This is done by the ↵Evan Cheng2009-06-182-2/+11

This is important for ARM register pair hints. - Register allocator should resolve the second part of the hint (register number) before passing it to the target since it knows virtual register to physical register mapping. - More fixes to get ARM load / store double word working. llvm-svn: 73671

* Rename RemoveCopiesFromValNo to TurnCopiesFromValNoToImpDefs.Evan Cheng2009-06-162-10/+10
| | | | llvm-svn: 73479
* If a val# is defined by an implicit_def and it is being removed, all of the ↵Evan Cheng2009-06-161-20/+27
| | | | | | | | copies off the val# were removed. This causes problem later since the scavenger will see uses of registers without defs. The proper solution is to change the copies into implicit_def's instead. TurnCopyIntoImpDef turns a copy into implicit_def and remove the val# defined by it. This causes an scavenger assertion later if the def reaches other blocks. Disable the transformation if the value live interval extends beyond its def block. llvm-svn: 73478

* Part 1.Evan Cheng2009-06-155-86/+39
| | | | | | | | | | | | | | | | | | | | | - Change register allocation hint to a pair of unsigned integers. The hint type is zero (which means prefer the register specified as second part of the pair) or entirely target dependent. - Allow targets to specify alternative register allocation orders based on allocation hint. Part 2. - Use the register allocation hint system to implement more aggressive load / store multiple formation. - Aggressively form LDRD / STRD. These are formed *before* register allocation. It has to be done this way to shorten live interval of base and offset registers. e.g. v1025 = LDR v1024, 0 v1026 = LDR v1024, 0 => v1025,v1026 = LDRD v1024, 0 If this transformation isn't done before allocation, v1024 will overlap v1025 which means it more difficult to allocate a register pair. - Even with the register allocation hint, it may not be possible to get the desired allocation. In that case, the post-allocation load / store multiple pass must fix the ldrd / strd instructions. They can either become ldm / stm instructions or back to a pair of ldr / str instructions. This is work in progress, not yet enabled. llvm-svn: 73381
