Subject: [PATCH 0/7] plugins: Use unwind info for special gdb registers
Date: Mon, 15 Apr 2024 21:05:26 -0700 [thread overview]
Message-ID: <20240416040539.1313535-1-richard.henderson@linaro.org> (raw)
Based-on: 20240404230611.21231-1-richard.henderson@linaro.org
("[PATCH v2 00/21] Rewrite plugin code generation")
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. :-)

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
