gamecube crt0.o source file ?

[happy_bunny]

I would like to have a look at the source for

C:\devkitPro\devkitPPC\powerpc-eabi\lib\crt0.o

does anyone know the location of the crt0.s (gamecube not wii) also whats the name of the linker script and its location for the gamecube ?

Code: Select all

$ nm -l /opt/devkitPro/devkitPPC/powerpc-eabi/lib/crt0.o
00000000 G __atexit
         U __bss_start
         U __sbss_end
         U __sbss_start
         U __stack
         U _end
00000004 T _start	/home/davem/projects/devkitpro/buildscripts/.devkitPPC/powerpc-eabi/newlib/powerpc-eabi/libgloss/rs6000/crt0.S:62
         U atexit	crt0.S:0
         U exit	/home/davem/projects/devkitpro/buildscripts/.devkitPPC/powerpc-eabi/newlib/powerpc-eabi/libgloss/rs6000/crt0.S:125
         U main	/home/davem/projects/devkitpro/buildscripts/.devkitPPC/powerpc-eabi/newlib/powerpc-eabi/libgloss/rs6000/crt0.S:122

So the source is in newlib/powerpc-eabi/libgloss/rs6000/crt0.S (i.e. download the newlib source or have the buildscripts do it for you).

The linker scripts are in buildscripts/dkppc/crtls/

That's probably not the crt0 you're looking for - libogc contains it's own crt0. The one at powerpc-eabi\lib\crt0.o is simply there to avoid problems when configuring autotools based projects and libraries for cross compilation.
