[PULL 22/52] tcg: Split tcg_gen_callN |
Date: |
Mon, 5 Jun 2023 13:15:18 -0700 |
Make tcg_gen_callN a static function. Create tcg_gen_call[0-7]
functions for use by helper-gen.h.inc.
Removes a multiplicty of calls to __stack_chk_fail, saving up
to 143kiB of .text space as measured on an x86_64 host.
