arc/gas: default mach is arc700, initialised in md_begin
This commit restructures the selection of the default cpu/mach so that
the choice is made from md_begin (if the user has not provided a command
line choice). This will reduce the amount of change needed in a later
patch.
At the request of Synopsys, the default architecture changes to ARC700
from this commit, previously the default was a non-existent
super-architecture that contained all instructions from all arc
variants. There's some clean up associated with removing the default
merged architecture, and a small test fix now that the default is
ARC700.
binutils/ChangeLog:
* testsuite/binutils-all/objdump.exp (cpus_expected): Add ARC700
to the architecture list.
gas/ChangeLog:
* config/tc-arc.c (arc_target): Delay initialisation until
arc_select_cpu.
(arc_target_name): Likewise.
(arc_features): Likewise.
(arc_mach_type): Likewise.
(cpu_types): Remove "all" entry.
(arc_select_cpu): New function, most of the content is from...
(md_parse_option): ... here. Call new arc_select_cpu.
(md_begin): Call arc_select_cpu if needed, default is now arc700.
include/ChangeLog:
* opcode/arc.h (ARC_OPCODE_BASE): Delete.
opcodes/ChangeLog:
* arc-opc.c (BASE): Delete.
