+ * sysdeps/unix/sysv/linux/mips/makecontext.S: Likewise.
+ * sysdeps/unix/sysv/linux/mips/mips32/Makefile: Include new test for
+ mips o32.
+ * sysdeps/unix/sysv/linux/mips/mips32/bug-getcontext-mips-gp.c: Added
+ new test for mips o32.
+ * sysdeps/unix/sysv/linux/mips/setcontext.S: Define MCONTEXT_SZGREG as
+ 8 and use it when copying general purpose registers.
+ * sysdeps/unix/sysv/linux/mips/swapcontext.S: Likewise.
