Subject: dumpstack: x86: various small unification steps, fix
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=6a2ae2d9f9212de47c16e23080162aada882c8b6;p=openwrt%2Fstaging%2Fblogic.git

dumpstack: x86: various small unification steps, fix

After "dumpstack: x86: various small unification steps", the
assembler gives the following compile error. The error is in
dumpstack_64.c.

{standard input}: Assembler messages:
{standard input}:720: Error: Incorrect register `%rbx' used with `l' suffix
{standard input}:1340: Error: Incorrect register `%r12' used with `l' suffix

Indeed the suffix in get_bp() was wrong.
