Subject: [PATCH] SH: Do not build syscalls if option provided
Date: Sun, 14 Aug 2022 00:22:50 +0800 [thread overview]
Message-ID: <20220813162250.125537-1-imi415@imi.moe> (raw)
This patch makes syscalls for SH architecture respecting the global option
"--disable-newlib-supplied-syscalls". This is useful when a bare-metal
toolchain is needed.
