Update of /cvsroot/linux-vax/toolchain/scripts
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv23835
Modified Files:
build_toolchain.sh
Log Message:
- Install uClibc
- Fiddle a bit with symlinks to allow GCC to actually find the library
as well as the matching header files.
- This results in a somewhat working userland compiler.
- exit(xx) is broken at the moment. crt1.S is supposed to push a function
pointer (named rtld_fini) on the stack (to be passed to __uClibc_main()),
but I don't know what it is supposed to be, so I just pushed 0x00000002,
but that gets executed as a function pointer (and we crash, obviously).
- If you use _exit(), it'll work.
- I could push 0x00000000 instead (the value is checked to not be a NULL
pointer before being referenced), but that wouldn't remind me that
there's still a broken spot. So I prefer seeing the application crash
instead.
