From: Yao Qi Date: Thu, 26 Jan 2017 14:29:19 +0000 (+0000) Subject: Refactor disassembly code X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e47ad6c0bd7aa388b1bd488f6ef522c20c0b94ed;p=binutils-gdb.git Refactor disassembly code This patch addes class gdb_disassembler, and refactor code to use it. The gdb_disassembler object is saved in disassember_info.application_data. However, disassember_info.application_data is already used by gdb for arm, mips spu, and scm-disasm. In arm and mips, .application_data is gdbarch, but we can still get gdbarch from gdb_disassember. The use of application_data in spu is a little bit complicated. It creates its own disassemble_info, and save spu_dis_asm_data in .application_data. This will overwrite the pointer to gdb_disassembler, so we need to find another place to save spu_dis_asm_data. I extend disassemble_info, and put "id" there. gdb: 2017-01-26 Pedro Alves Yao Qi * arm-tdep.c: Include "disasm.h".
