Subject: * valops.c (value_assign): 'use_buffer' is initialized to zero,
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=6c4182ddc9e707f2bb12ee248458e3082ad28ce4;p=binutils-gdb.git

* valops.c (value_assign): 'use_buffer' is initialized to zero,
and never assigned to.   Delete it, and the 'if (use_buffer)'
clauses.  Delete 'raw_buffer', since it is now unused.
