Subject: 	[PATCH] opcodes/i386-dis.c is not thread-safe
Date: 	Mon, 20 Dec 2021 15:04:17 -0800
From: 	vladimir.mezentsev@oracle.com

To: 	binutils@sourceware.org



From: Vladimir Mezentsev <vladimir.mezentsev@oracle.com>


We plan to use print_insn_i386_att, print_insn_i386_intel and
print_insn_i386 in a multithreaded application.
These functions are not thread safe due to the use of static variables.

Tested on x86_64-pc-linux-gnu.

opcodes/ChangeLog:
2021-12-20 Vladimir Mezentsev <vladimir.mezentsev@oracle.com>

* opcodes/i386-dis.c: Make print_insn_i386_att, print_insn_i386_intel
and print_insn_i386 thread-safe
