Patch for sysdeps/unix/sysv/linux/mips/brk.c
- From: "Joseph S. Myers" <joseph at codesourcery dot com>
- To: libc-alpha at sourceware dot org
- Date: Wed, 4 Jan 2006 01:25:49 +0000 (UTC)
- Subject: Patch for sysdeps/unix/sysv/linux/mips/brk.c
sysdeps/unix/sysv/linux/mips/brk.c calls a syscall but fails to use the
full set of clobbers for syscalls on MIPS Linux. For safety it should use
__SYSCALL_CLOBBERS the way all the other MIPS syscall definitions do.
2006-01-04 Joseph S. Myers <joseph@codesourcery.com>
* sysdeps/unix/sysv/linux/mips/brk.c (__brk): Use
__SYSCALL_CLOBBERS.
