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/thread/sh/syscall_cp.s | 39 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 39 insertions(+) create mode 100644 src/thread/sh/syscall_cp.s (limited to 'src/thread/sh/syscall_cp.s') diff --git a/src/thread/sh/syscall_cp.s b/src/thread/sh/syscall_cp.s new file mode 100644 index 00000000..5677b9c0 --- /dev/null +++ b/src/thread/sh/syscall_cp.s @@ -0,0 +1,39 @@ +.text +.global __syscall_cp_asm +.type __syscall_cp_asm, @function +__syscall_cp_asm: + +.global __cp_begin +__cp_begin: + mov.l @r4, r4 + tst r4, r4 + bt 2f + + mov.l L1, r0 + braf r0 + nop +1: + +.align 2 +L1: .long __cancel@PLT-(1b-.) + +2: mov r5, r3 + mov r6, r4 + mov r7, r5 + mov.l @r15, r6 + mov.l @(4,r15), r7 + mov.l @(8,r15), r0 + mov.l @(12,r15), r1 + trapa #22 + +.global __cp_end +__cp_end: + ! work around hardware bug + or r0, r0 + or r0, r0 + or r0, r0 + or r0, r0 + or r0, r0 + + rts + nop -- cgit v1.2.1
