R3000 stack docs

[Mark and Janice Juszczec]

Hi folks

I'm trying to compile uClibc fur use on my Helio pda.  There is some kind of 
problem with the stack layout.  The one uClibc expects isn't what my kernel 
is putting together.

I'm trying to find out the stack layout for the
Toshiba TMPR3912AU, 75 MHz., 32-bit RISC processor so I can figure out what 
I'm getting out of the kernel.

There is one in ftp://www.linux-mips.org/pub/linux/mips/doc/ABI/mipsabi.pdf

Does this refer to the stack the kernel loads in binfmt_elf.c and is it the 
correct place to start?

Thanks

Mark

Thanks

Mark

The ABI only describes the stack frame used by functions and for their
arguments.  The arguments as passed to an invoked program are not subject
to the ABI documents though obviously the layout is choose such that it
can be passed to the program's main() without costly conversion.  I
therefore suggest you simply read binfmt_elf.c - that part is fairly
straight forward.
