Subject: Remove write-only assignment in rs6000-tdep.c
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=27e9ff87a627614fda7ddd89ddef745de5e988bb;p=binutils-gdb.git

Remove write-only assignment in rs6000-tdep.c

The result of this memory read is never used, so it can be removed.

gdb/ChangeLog:

	* rs6000-tdep.c (ppc_deal_with_atomic_sequence): Remove
	write-only assignment to "insn" variable.
