Vikram S. Adve 985b6e3d13 Eliminate unused function.
llvm-svn: 310
2001-07-28 04:15:45 +00:00
Vikram S. Adve 150460321e Bug fixes:
Store bool result in register after SetCC if the bool value
is used by anything other than a branch.
Forward-substitute operand of a VM instruction for which no
machine instruction is generated (e.g., Cast).
Other changes due to changes to classes TargetMachine and MachineInstr.

Vikram S. Adve c429691751 Added MachineInstrInfo class and moved instruction-related members there.
Added several fields to MachineInstrDescriptor (and renamed it from
MachineInstrInfo.  Latency fields are to support scheduling.

Chris Lattner 89d4dfbfba Add an arg to insertVal to allow us to prevent builtin types from being ignored
when they are inserted.

Ignore constant values without names.  If they are used, they will be inlined.
