From: Yao Qi Date: Mon, 16 Nov 2015 14:50:29 +0000 (+0000) Subject: Pass value * instead of bfd_byte * to pass_* functions in aarch64-tdep.c X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=8e80f9d1d5cc0884ea1e677f796c69c36a5893cd;p=binutils-gdb.git Pass value * instead of bfd_byte * to pass_* functions in aarch64-tdep.c This patch changes the last argument of functions pass_in_x_or_stack, pass_in_v_or_stack, pass_on_stack, and pass_in_x to type value *. gdb: 2015-11-16 Yao Qi * aarch64-tdep.c (pass_in_x_or_stack): Change argument type from bfd_byte * to value *. Caller updated. (pass_in_x): Likewise. (pass_in_v_or_stack): Likewise.
