* infptrace.c (store_inferior_registers): Move some common code out
|
||||||
|
to store_register, like fetch_inferior_registers & fetch_register.
|
||||||
|
(store_register): New function, from store_inferior_registers.
|
||||||
|
(fetch_inferior_registers, fetch_register): Minor code tweaks to
|
||||||
|
make {fetch,store}_inferior_registers and {fetch,store}_register
|
||||||
|
routines as similar in structure as possible.
|
||||||
|
(fetch_inferior_registers, store_inferior_registers): Eliminate
|
||||||
|
local variable numregs and just use ARCH_NUM_REGS directly.
