Re: [PATCH] add misc cell spu POSIX functions


Patch checked in.

-- Jeff J.

The attached patch is for the cell spu and adds some POSIX functions to libgloss that the fortran compiler is fond of having. It's a straightforward patch. Originally authored by Sa, forward ported by me.

2006-12-12 Sa Liu <saliu@de.ibm.com>

* spu/access.c: New file
* spu/dup.c: New file
* spu/ftruncate.c: New file
* spu/jsre.h: add structures for new functions
* spu/time.c: New file
* spu/Makefile.in (access.o, dup.o, ftruncate.o, time.o): New targets.
