2024-04-30plugins: Replace pr_ops with a proper debug dump flagRichard Henderson
The DEBUG_PLUGIN_GEN_OPS ifdef is replaced with "-d op_plugin". The second pr_ops call can be obtained with "-d op". Reviewed-by: Pierrick Bouvier <pierrick.bouvier@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>

2024-04-30tcg: Remove TCG_CALL_PLUGINRichard Henderson
Since we no longer emit plugin helpers during the initial code translation phase, we don't need to specially mark plugin helpers. Reviewed-by: Pierrick Bouvier <pierrick.bouvier@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2024-04-30plugins: Use emit_before_op for PLUGIN_GEN_FROM_MEMRichard Henderson
Introduce a new plugin_mem_cb op to hold the address temp and meminfo computed by tcg-op-ldst.c. Because this now has its own opcode, we no longer need PLUGIN_GEN_FROM_MEM. Reviewed-by: Pierrick Bouvier <pierrick.bouvier@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2024-04-30plugins: Use emit_before_op for PLUGIN_GEN_AFTER_INSNRichard Henderson
Introduce a new plugin_cb op and migrate one operation. By using emit_before_op, we do not need to emit opcodes early and modify them later -- we can simply emit the final set of opcodes once.
