Hi,
this patch removes another bunch of current_gdbarch's in xtensa port.
There was the AREG_NUMBER macro which is very complicated and hard to understand. I replaced
this one by a function which is equivalent (proven by a little test programm).
I'd really like to see a testsuite run on xtensa with this patch but I don't have access to such a machine.
Maybe anyone of you has and is willing to test the patch? This would be great.
Furthermore this patch add gdbarch to some of the macros and replaces current_gdbarch with it.
Tested by building with --target=xtensa. Ok to commit?
ChangeLog:
* xtensa-tdep.c (ARG_1ST): Replace ARGS_FIRST_REG by its expression.
(ARGS_FIRST_REG): Remove.
(areg_numer): New function.
(xtensa_pseudo_register_read, xtensa_frame_prev_register)
(xtensa_extract_return_value, xtensa_store_return_value)
(xtensa_frame_cache): Replace AREG_NUMBER by areg_number.
(AREG_NUMBER): Remove.
(XTENSA_IS_ENTRY, ARG_NOF, ARG_1ST): Add gdbarch as parameter.
(xtensa_frame_cache): Update use of XTENSA_IS_ENTRY.
(xtensa_push_dummy_call): Update use of ARG_NOF.
(extract_call_winsize): Add gdbarch as parameter. Replace
current_gdbarch by gdbarch.
(xtensa_extract_return_value, xtensa_store_return_value): Update call
of extract_call_winsize.
