Subject: [PATCH 3/6] Call print_insn_mep in mep_gdb_print_insn
Date: Wed, 25 Jan 2017 08:38:00 -0000 [thread overview]
Message-ID: <1485333480-20515-4-git-send-email-yao.qi@linaro.org> (raw)
In-Reply-To: <1485333480-20515-1-git-send-email-yao.qi@linaro.org>
opcodes/mep-dis.c:mep_print_insn has already had the code to
handle the case when info->section is NULL,
/* Picking the right ISA bitmask for the current context is tricky. */
if (info->section)
{
}
else /* sid or gdb */
{
}
so that we can still cal print_insn_mep even section can't be found.
On the other hand, user can disassemble an arbitrary address which
doesn't map to any section at all.
gdb:
2017-01-10 Yao Qi <yao.qi@linaro.org>
* mep-tdep.c (mep_gdb_print_insn): Set info->arch
to bfd_arch_mep. Don't return 0 if section is not
found. Call print_insn_mep.
