* tcg: Hoist max_insns computation to tb_gen_codeRichard Henderson2019-04-241-1/+2
| | | | | | | | | | In order to handle TB's that translate to too much code, we need to place the control of the length of the translation in the hands of the code gen master loop.

* translator: merge max_insns into DisasContextBaseEmilio G. Cota2018-05-091-4/+4
| | | | | | | | | | | While at it, use int for both num_insns and max_insns to make sure we have same-type comparisons.

Removed pc_next return from translate_insn. Removed tcg_check_temp_count from generic loop. Moved gen_io_end to exactly match gen_io_start. Use qemu_log instead of error_report for temporary leaks. Moved TB size/icount assignments before disas_log.] Signed-off-by: Richard Henderson <rth@twiddle.net>
* target: [tcg] Use a generic enum for DISAS_ valuesLluís Vilanova2017-09-061-0/+40
Used later. An enum makes expected values explicit and bounds the value space of switches. Signed-off-by: Lluís Vilanova <vilanova@ac.upc.edu> Reviewed-by: Emilio G.
