About porting newlib to arm...

[Yen-Ting Chen]

Dear all,

Could anyone tell me what is the difference between these directories,
and what I can make use of from these directories?

1) newlib-<version>/libgloss/arm/
2) newlib-<version>/newlib/libc/machine/arm/
3) newlib-<version>/newlib/libc/sys/arm

If I want to port newlib to arm, should I modify
newlib-<version>/newlib/libc/syscalls/*.c or just
newlib-<version>/newlib/libc/sys/arm/syscalls.c ?
And do I need to do with newlib-<version>/libgloss/arm ??

Thanks in advance.
