Subject: PPC fix for stfiwx instruction (and additional stores with primary opcode of 31)
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1284c2264cca5c848e2f9622ea53e42c97e4e838;p=binutils-gdb.git

PPC fix for stfiwx instruction (and additional stores with primary opcode of 31)

[gdb] Fix address being recorded in rs6000-tdep.c, ppc_process_record_op31.

The GDB record function was recording the variable addr that was passed in
rather than the calculated effective address (ea) by the
ppc_process_record_op31 function.
