From: Yao Qi Date: Tue, 7 Jul 2015 15:58:19 +0000 (+0100) Subject: Remove {fetch,store}_fpregister and {fetch,store}_register X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=179bfe826ba62ca8aa43f3d20cc1b21dfc41b1d0;p=binutils-gdb.git Remove {fetch,store}_fpregister and {fetch,store}_register This patch is to remove fetch_fpregister, fech_register, store_fpregister and store_register, and use fetch_fpregs, fetch_regs, store_regs, and store_fpregs instead. gdb: 2015-07-07 Yao Qi * arm-linux-nat.c (store_fpregister): Remove. (store_register): Likewise. (fetch_fpregister): Likewise. (fetch_register): Likewise. (arm_linux_store_inferior_registers): Call store_regs and store_fpregs instead. (arm_linux_fetch_inferior_registers): Call fetch_fpregs and fetch_regs instead. --- diff --git a/gdb/ChangeLog b/gdb/ChangeLog index d6d45bfba1b..5cfd3ae7b24 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,14 @@ +2015-07-07 Yao Qi + + * arm-linux-nat.c (store_fpregister): Remove. + (store_register): Likewise. + (fetch_fpregister): Likewise. + (fetch_register): Likewise. + (arm_linux_store_inferior_registers): Call store_regs and + store_fpregs instead. + (arm_linux_fetch_inferior_registers): Call fetch_fpregs and + fetch_regs instead. + 2015-07-06 Andrew Burgess * doc/gdb.texinfo (TUI): Restructure documentation on TUI layout diff --git a/gdb/arm-linux-nat.c b/gdb/arm-linux-nat.c index c167bce18b3..5a8880f3c08 100644 --- a/gdb/arm-linux-nat.c +++ b/gdb/arm-linux-nat.c @@ -82,47 +82,6 @@ get_thread_id (ptid_t ptid) #define GET_THREAD_ID(PTID) get_thread_id (PTID) -/* Get the value of a particular register from the floating point - state of the process and store it into regcache. */ - -static void -fetch_fpregister (struct regcache *regcache, int regno) -{ - int ret, tid;
