2013-03-03gen-icount.h: Rename gen_icount_start/end to gen_tb_start/endPeter Maydell1-2/+2
The gen_icount_start/end functions are now somewhat misnamed since they are useful for generic "start/end of TB" code, used for more than just icount. Rename them to gen_tb_start/end.

There is some read-after-write error within the OP=2 insns which prevents setting cpu_dst to the real output register. Until this is found and fixed, always write to a temporary first.

2012-10-20target-sparc: Remove cpu_tmp0 as a globalRichard Henderson1-85/+118
Subroutines do their own local temporary management. Within disas_sparc_insn we limit the existance of the variable to OP=2 insns, and delay initialization as late as is reasonable for the specific XOP.

2012-10-13target-sparc: Don't compute full flags value so oftenRichard Henderson1-19/+11

There are 6 temporaries that disas_sparc_insn relies on having been allocated. Now that they are no longer referenced across branches, they need not be allocated as local temps.

Share more code between unconditional and conditional paths. Move the computation of the trap number into the conditional BB; avoid using temporaries that have gone out of scope (cpu_tmp32) or rely on local temps (cpu_dst). Fully fold the exception number when the trap number is %g0+imm. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
