| | | | | | | | one Value with another one in all operands and implicit references of the machine instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@3306 91177308-0d34-0410-b5e6-96231b3b80d8

* Add support for marking each operand as a %hh, %hm, %lm or %lo.Vikram S. Adve2002-07-101-34/+38
| | | | | | | | Represent previous bools and these ones with flags in a single byte per operand. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2860 91177308-0d34-0410-b5e6-96231b3b80d8
* Moved class MachineCodeForBasicBlock to MachineCodeForBasicBlock.{cpp,h}.Vikram S. Adve2002-07-081-11/+25
| | | | | | | | | An (explicit or implicit) operand may now be both a def and a use. Also add a set of regs used by each instruction. dump() no longer takes an optional argument, which doesn't work in gdb. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2821 91177308-0d34-0410-b5e6-96231b3b80d8

* 1. Add a bottom-up pass on BURG trees that is used to fix constant operands.Vikram S. Adve2001-10-171-2/+3
| | | | | | | | | | Needs to be bottom up because constant values may be forward-substituted to their uses (i.e., into the parent in the BURG tree). 2. Move most of the constant-fixup code into machine-indepedent file InstrSelectionSupport.cpp. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@859 91177308-0d34-0410-b5e6-96231b3b80d8
