* target-mips: fix conditional moves off fp condition codesNathan Froyd2009-08-251-5/+5
| | | | | | | | | | | | | | Conditional moves off fp condition codes were using the result of get_fp_bit to isolate and test the relevant condition code. However, get_fp_bit returns the bit number of the condition code, not a bitmask. (Compare the use of get_fp_bit in gen_compute_branch1, for instance.) Fixed by shifting a bitmask into place using the result of get_fp_bit in the relevant functions (gen_mov{ci,cf_s,cf_d,cf_ps}).

* target-mips: fix call to check_*() functionsaurel322009-04-161-12/+24
| | | | | | | | | | check_*() functions may in fine call generate_exception(), which ends by a call to tcg_gen_exit_tb(). As a consequence, we have to make sure that no TCG temp variables are crossing a check_*() function.
