2012-10-07target-sparc: Optimize conditionals using SUBCCRichard Henderson
Aka "normal" comparisons. We now have the infrastructure to pass back non-boolean results from gen_compare. This will automatically get used by both branches and conditional moves. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-10-07target-sparc: Fall through from not-taken trapRichard Henderson
Now that we've cleaned up global temporary allocation, we can continue translating the fallthru path of a conditional trap. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-10-07target-sparc: Cleanup "global" temporary allocationRichard Henderson
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. Move the allocation/free of these temporaries to make it clear that they are local to the translation of a single insn.

2012-10-07target-sparc: Move taddcctv and tsubcctv out of lineRichard Henderson
The branches around the exception are maintaining an otherwise unnecessary use of local temps for the cpu destination. Note that gen_op_t{add,sub}_cc were identical to gen_op_{add,sub}_cc. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-10-07target-sparc: Tidy TccRichard Henderson
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>

For all targets that currently call tcg_gen_debug_insn_start, add CPU_LOG_TB_OP_OPT to the condition that gates it.

Now that CONFIG_TCG_PASS_AREG0 is enabled for all targets, remove dead code and support for !CONFIG_TCG_PASS_AREG0 case. Remove dyngen-exec.h and all references to it. Although included by hw/spapr_hcall.c, it does not seem to use it. Remove unused HELPER_CFLAGS. Signed-off-by: Blue Swirl <blauwirbel@gmail.com> Reviewed-by: Richard Henderson <rth@twiddle.net>
2012-09-08target-sparc: fix fcmp{s,d,q} instructions wrt exceptionAurelien Jarno
fcmp{s,d,q} instructions are supposed to ignore quiet NaN (contrary to the fcmpe{s,d,q} instructions), but the current code is wrongly setting the NV exception in that case. Moreover the current code is duplicated: first the arguments are checked for NaN to generate an exception, and later in case the comparison is unordered (which can only happens if one of the argument is a NaN), the same check is done to generate an exception. Fix that by calling clear_float_exceptions() followed by check_ieee_exceptions() as for the other floating point instructions. Use the _compare_quiet functions for fcmp{s,d,q} and the _compare ones for fcmpe{s,d,q}. Simplify the flag setting by not clearing a flag that is set the line just below. This fix allows the math glibc testsuite to pass. Cc: Blue Swirl <blauwirbel@gmail.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

In commit 1bba0dc932e8826a7d030df3767daf0bc339f9a2 cpu_reset() was renamed to cpu_state_reset(), to allow introducing a new cpu_reset() that would operate on QOM objects. All callers have been updated except for one in target-mips, so drop all implementations except for the one in target-mips and move the declaration there until MIPSCPU reset can be fully QOM'ified.
