* 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74110 91177308-0d34-0410-b5e6-96231b3b80d8

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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73478 91177308-0d34-0410-b5e6-96231b3b80d8
