Re: Question regarding compiling a toolchain for a Broadcom SB1


Ok, I -think- I've found one problem.

Identifying the processor as an SB1 may be producing a
confused result.

Both binutils and glibc's configure scripts will see
it as a mips32, because it does not start off with
mips64 in the name.

However, GCC's configure scripts expands the name to
mipsisa64sb1, which implies it is seeing the processor
as a 64-bit architecture.

None of the above test for whether the sb1-fix flag
needs to be set (which fixes a couple of
floating-point bugs in the processor), though I think
I'm safe in assuming that the compiler and binutils
won't be doing much in the way of floating-point
arithmetic and I can worry about glibc's FP code when
I get to the point of building a native copy.
