This is an attempt to fix https://gitlab.com/qemu-project/qemu/-/issues/2208 ("PC is not updated for each instruction in TCG plugins") I have only updated target/i386 so far, but basically all targets need updating for the new callbacks. Extra points to anyone who sees how to avoid the extra code duplication. :-) r~ Richard Henderson (7): tcg: Introduce INDEX_op_plugin_pc accel/tcg: Set CPUState.plugin_ra before all plugin callbacks accel/tcg: Return the TranslationBlock from cpu_unwind_state_data plugins: Introduce TCGCPUOps callbacks for mid-tb register reads target/i386: Split out gdb-internal.h target/i386: Introduce cpu_compute_eflags_ccop target/i386: Implement TCGCPUOps for plugin register reads include/exec/cpu-common.h | 9 +++-- include/hw/core/cpu.h | 1 + include/hw/core/tcg-cpu-ops.h | 13 +++++++ include/tcg/tcg-op-common.h | 1 + include/tcg/tcg-opc.h | 1 + target/i386/cpu.h | 2 + target/i386/gdb-internal.h | 65 +++++++++++++++++++++++++++++++ accel/tcg/plugin-gen.c | 50 +++++++++++++++++++++--- accel/tcg/translate-all.c | 9 +++-- plugins/api.c | 36 +++++++++++++++++- target/i386/gdbstub.c | 1 + target/i386/helper.c | 6 ++- target/i386/tcg/cc_helper.c | 10 +++++ target/i386/tcg/tcg-cpu.c | 72 +++++++++++++++++++++++++++-------- tcg/tcg-op.c | 5 +++ tcg/tcg.c | 10 +++++ 16 files changed, 258 insertions(+), 33 deletions(-) create mode 100644 target/i386/gdb-internal.h -- 2.34.1
