Uclinux-2008r1-rc8 (bf561) to VDSP5 transplantation (in):. rept

In Arch/blackfin/mach-common/entry. There are several lines in S:

.rept NR_syscalls-(.-_sys_call_table)/4
.long _sys_ni_syscall
.endr

Here the value of the nr_syscalls is

#define __NR_syscall　　357
#define NR_syscalls　　　__NR_syscall

The (.-_sys_call_table)/4 calculates the currently defined number of entries, with a value of 357, so there is no need to repeat the definition here, and the three lines are commented out directly.

Below, there are several lines that define:

_exception_stack:
.rept 1024
.long 0;
.endr
_exception_stack_top:

is simply to define a buffer, which is changed directly to:

_exception_stack:
//　　　　 .rept 1024
//　　　　 .long 0;
//　　　　 .endr
　　　　　　 .byte4 _exception_stack_buffer[1024];
_exception_stack_top:
