linuxthreads changes for mips64-linux
- From: Alexandre Oliva <aoliva at redhat dot com>
- To: libc-alpha at sources dot redhat dot com
- Date: 14 Mar 2003 00:48:56 -0300
- Subject: linuxthreads changes for mips64-linux
- Organization: GCC Team, Red Hat
This makes the mips-specific code in linuxthreads comply with n32 and
n64 as well.

2003-03-14 Alexandre Oliva <aoliva at redhat dot com>
* sysdeps/mips/pspinlock.c (__pthread_spin_lock): Don't .set
mips2 on new abi.
* sysdeps/mips/pt-machine.h (__compare_and_swap): Likewise.
Handle 64-bit longs on n64.
