Subject: [PATCH v2 3/6] RISC-V: Optimize riscv_disassemble_data printf
Date: Mon, 26 Sep 2022 12:26:52 +0000 [thread overview]
Message-ID: <814280d8a026944315caf86eafb35943d10beed6.1664195181.git.research_trasio@irq.a4lg.com> (raw)
In-Reply-To: <cover.1664195181.git.research_trasio@irq.a4lg.com>
This commit makes types of printf arguments on riscv_disassemble_data
as small as possible (as long as we can preserve the portability) to reduce
the cost of printf (especially on 32-bit host).
opcodes/ChangeLog:
* riscv-dis.c (riscv_disassemble_data): Use smallest possible type
to printing data.
