2001-03-07 Richard Sandiford <rsandifo@redhat.com> * (libc/include/machine/setjmp.h): Use 23 DI-mode ints for a jmpbuf on MIPS64 targets. * (libc/machine/mips/setjmp.S): Add MIPS64 version.

* libc/include/machine/setjmp.h: For mips, define _JBLEN based based on __mips_soft_float rather than __mips64. * libc/machine/mips/setjmp.S: Provide hard and soft float versions of both 32-bit and 64-bit code.
