2005-12-26Added field noResults to Instruction.Evan Cheng
Currently tblgen cannot tell which operands in the operand list are results so it assumes the first one is a result. This is bad. Ideally we would fix this by separating results from inputs, e.g. (res R32:$dst), (ops R32:$src1, R32:$src2). But that's a more distruptive change. Adding 'let noResults = 1' is the workaround to tell tblgen that the instruction does not produces a result. It works for now since tblgen does not support instructions which produce multiple results. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25017 91177308-0d34-0410-b5e6-96231b3b80d8
2005-12-23* Removed the use of FLAG. Now use hasFlagIn and hasFlagOut instead.Evan Cheng
* Added a pseudo instruction (for each target) that represent "return void". This is a workaround for lack of optional flag operand (return void is not lowered so it does not have a flag operand.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24997 91177308-0d34-0410-b5e6-96231b3b80d8

2005-12-20Reserve G1 for frame offset stuff and use it to handle large stack frames.Chris Lattner
For example, instead of emitting this: test: save -40112, %o6, %o6 ;; imm too large add %i6, -40016, %o0 ;; imm too large call caller nop restore %g0, %g0, %g0 retl nop emit this: test: sethi 4194264, %g1 or %g1, 848, %g1 save %o6, %g1, %o6 sethi 4194264, %g1 add %g1, %i6, %g1 add %i1, 944, %o0 call caller nop restore %g0, %g0, %g0 retl nop which doesn't cause the assembler to barf. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24880 91177308-0d34-0410-b5e6-96231b3b80d8

we were storing into [FP+88] instead of [FP+92]. Improve codegen by emitting [FP+92], instead of emitting a copy of FP into another GPR which wouldn't be coallesced because FP isn't register allocated. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24859 91177308-0d34-0410-b5e6-96231b3b80d8
