As occasionally discussed on this list, due to licensing conflicts, we are restricted to a version of libopcodes that pre-dates its upstream re-licensing to gplv3. That makes our copy rather old and dated.
I've already seen this as problematic for s390x guest. I'm sure the same problem exists for Power8+, though I haven't looked. As we go forward with vector operations we'll see this for x86 host. An alternative is to use a BSD-licensed disassembler: https://www.capstone-engine.org/ This is an actively maintained project derived from llvm. Moreover, it is already in the major Linux distributions, which makes it easy to phase in its use. I've arranged the code such that we attempt to use capstone first, and if that initialization fails, fall back to the existing code from binutils. r~ Richard Henderson (10): target/i386: Convert to disas_set_info hook target/ppc: Convert to disas_set_info hook disas: Remove unused flags arguments disas: Support the Capstone disassembler library target/i386: Support Capstone in disas_set_info target/arm: Support Capstone in disas_set_info target/ppc: Support Capstone in disas_set_info target/s390x: Support Capstone in disas_set_info target/sparc: Support Capstone in disas_set_info target/mips: Support Capstone in disas_set_info include/disas/bfd.h | 4 ++ include/disas/capstone.h | 38 ++++++++++ include/disas/disas.h | 4 +- include/exec/log.h | 4 +- target/mips/cpu.h | 2 + disas.c | 161 +++++++++++++++++++++++------------------- monitor.c | 29 +------- target/alpha/translate.c | 2 +- target/arm/cpu.c | 21 +++++- target/arm/translate-a64.c | 3 +- target/arm/translate.c | 3 +- target/cris/translate.c | 3 +- target/hppa/translate.c | 2 +- target/i386/cpu.c | 19 +++++ target/i386/translate.c | 8 +-- target/lm32/translate.c | 2 +- target/m68k/translate.c | 2 +- target/microblaze/translate.c | 2 +- target/mips/cpu.c | 8 --- target/mips/translate.c | 2 +- target/mips/translate_init.c | 36 ++++++++++ target/nios2/translate.c | 2 +- target/openrisc/translate.c | 2 +- target/ppc/translate.c | 5 +- target/ppc/translate_init.c | 27 +++++++ target/s390x/cpu.c | 2 + target/s390x/translate.c | 2 +- target/sh4/translate.c | 2 +- target/sparc/cpu.c | 3 + target/sparc/translate.c | 2 +- target/tricore/translate.c | 2 +- target/unicore32/translate.c | 2 +- target/xtensa/translate.c | 2 +- configure | 17 +++++ 34 files changed, 279 insertions(+), 146 deletions(-) create mode 100644 include/disas/capstone.h -- 2.13.5
