[PATCH] spu syscalls
- From: Kazunori Asayama <asayama at sm dot sony dot co dot jp>
- To: newlib at sourceware dot org
- Date: Wed, 23 Aug 2006 12:53:01 +0900 (JST)
- Subject: [PATCH] spu syscalls
Hi,
The attached patch divides single SPU system call implementation file
"syscalls.c" into individual files to avoid linking unused code.
2006-08-23 Kazunori Asayama <asayama@sm.sony.co.jp>
* spu/Makefile.in: Add new object files.
* spu/syscalls.c: Move each system call to individual file.
* spu/jsre.h: Add declaration of _send_to_ppe_0x2101().
* spu/close.c: New file. Moved from spu/syscalls.c.
* spu/fstat.c: Likewise.
* spu/getpid.c: Likewise.
* spu/isatty.c: Likewise.
* spu/kill.c: Likewise.
* spu/lseek.c: Likewise.
* spu/open.c: Likewise.
* spu/read.c: Likewise.
* spu/stat.c: Likewise.
* spu/unlink.c: Likewise.
* spu/write.c: Likewise.
