Subject: Decode TLS syscalls on m68k
X-Git-Tag: v4.6~110
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=587432273982c136809a6e9182e8ecf674648706;p=strace

Decode TLS syscalls on m68k

* linux/m68k/syscallent.h: Add entries for get_thread_area,
set_thread_area, atomic_comxchg_32, atomic_barrier.
* linux/dummy.h (sys_get_thread_area, sys_set_thread_area) [M68K]:
Don't redefine.
* mem.c (sys_get_thread_area, sys_set_thread_area) [LINUX && M68K]: New.
