2005-12-23fix the int<->fp instructions, which apparently take a single float registerChris Lattner
to represent the int part (because it's always 32-bits) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24976 91177308-0d34-0410-b5e6-96231b3b80d8

2005-12-20Run lower-switch after lower-invoke.Chris Lattner
Only run lower-allocations and lower-select for the simple isel git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24881 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
2005-12-19Fix pifft by correcting the case when a i64/f64 straddles O5 and memory:Chris Lattner
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
