Commit Message
From: Tsukasa OI <research_trasio@irq.a4lg.com>
Since the 'Zca' extension is the new base of the compressed instructions,
this commit enables RVC *also* when the 'Zca' extension is enabled
via ".option arch" directive.
gas/ChangeLog:
* config/tc-riscv.c (s_riscv_option): Enable RVC also when the
'Zca' extension is enabled after an ".option arch" directive.
