* target: Clean up how the dump_mmu() printMarkus Armbruster2019-04-181-1/+1
| | | | | | | | | | | | | | | | | | | | | The various dump_mmu() take an fprintf()-like callback and a FILE * to pass to it, and so do their helper functions. Passing around callback and argument is rather tiresome. Most dump_mmu() are called only by the target's hmp_info_tlb(). These all pass monitor_printf() cast to fprintf_function and the current monitor cast to FILE *. SPARC's dump_mmu() gets also called from target/sparc/ldst_helper.c a few times #ifdef DEBUG_MMU. These calls pass fprintf() and stdout. The type-punning is technically undefined behaviour, but works in practice. Clean up: drop the callback, and call qemu_printf() instead.

This allows to use registers content in the monitor. Example: BEFORE: (qemu) print $d0 unknown register AFTER: (qemu) print $d0 0 (qemu) print $sr 0x2000 (qemu) x/10i $pc 0x40010a2a: movew %sr,%d0 0x40010a2c: oril #1792,%d0 0x40010a32: movew %d0,%sr 0x40010a34: movel %a0@,%d0 0x40010a36: btst #3,%d0 0x40010a3a: beqs 0x40010a26 0x40010a3c: movew %sr,%d0 0x40010a3e: andil #63743,%d0 0x40010a44: movew %d0,%sr 0x40010a46: rts Signed-off-by: Laurent Vivier <laurent@vivier.eu> Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Reviewed-by: Thomas Huth <huth@tuxfamily.org> Message-Id: <20171221083057.17942-1-laurent@vivier.eu>
