Subject: (reg_names): Make it static.  Use DEBUG_REGISTER_NAMES if that's defined.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=cf99a7342ba1ddd483d19eaacc85d7ab12205258;p=gcc.git

(reg_names): Make it static.  Use DEBUG_REGISTER_NAMES if that's defined.

(DEBUG_PRINT_REG): Define if not defined.
(print_rtx): Use DEBUG_PRINT_REG for hard regs.

(reg_name): Moved here.
