From aacd348637e38795dd7ae3c7c8c908d8c0cd24fd Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Thu, 27 Feb 2014 22:03:25 -0500 Subject: rename superh port to "sh" for consistency linux, gcc, etc. all use "sh" as the name for the superh arch. there was already some inconsistency internally in musl: the dynamic linker was searching for "ld-musl-sh.path" as its path file despite its own name being "ld-musl-superh.so.1". there was some sentiment in both directions as to how to resolve the inconsistency, but overall "sh" was favored. --- src/internal/sh/syscall.s | 22 ++++++++++++++++++++++ 1 file changed, 22 insertions(+) create mode 100644 src/internal/sh/syscall.s (limited to 'src/internal/sh/syscall.s') diff --git a/src/internal/sh/syscall.s b/src/internal/sh/syscall.s new file mode 100644 index 00000000..a8fda1c0 --- /dev/null +++ b/src/internal/sh/syscall.s @@ -0,0 +1,22 @@ +.global __syscall +.type __syscall, @function +__syscall: + !
