From ecbba30fbf45dceaaf0e8010638283e7aa94a4df Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Mon, 1 Mar 2021 23:48:24 +0900 Subject: mips: syscalls: switch to generic syscalltbl.sh Many architectures duplicate similar shell scripts. This commit converts mips to use scripts/syscalltbl.sh. This also unifies syscall_table_32_o32.h and syscall_table_64_o32.h into syscall_table_o32.h. The offset parameters are unneeded here; __SYSCALL(nr, entry) is defined as 'PTR entry', so the parameter 'nr' is not used in the first place. With this commit, syscall tables and generated files are straight mapped, which makes things easier to understand. syscall_n32.tbl --> syscall_table_n32.h syscall_n64.tbl --> syscall_table_n64.h syscall_o32.tbl --> syscall_table_o32.h Then, the abi parameters are also unneeded.
