* Change tblgen to emit FOOISD opcode names as twoChris Lattner2010-03-25
| | | | | | | | | | | | | | | bytes instead of one byte. This is important because we're running up to too many opcodes to fit in a byte and it is aggrevated by FIRST_TARGET_MEMORY_OPCODE making the numbering sparse. This just bites the bullet and bloats out the table. In practice, this increases the size of the x86 isel table from 74.5K to 76K. I think we'll cope :) This fixes rdar://7791648 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99494 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix evil TableGen bug in template parameters with defaults.Jakob Stoklund Olesen2010-03-25
| | | | | | | | | | If a TableGen class has an initializer expression containing an X.Y subexpression, AND X depends on template parameters, AND those template parameters have defaults, AND some parameters with defaults are beyond position 1, THEN parts of the initializer expression are evaluated prematurely with the default values when the first explicit template parameter is substituted, before the remaining explicit template parameters have been substituted. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99492 91177308-0d34-0410-b5e6-96231b3b80d8
