Building and Installing a Cross-Compiler
========================================
GNU CC can function as a cross-compiler for many machines, but not
all.
* Cross-compilers for the Mips as target using the Mips assembler
currently do not work, because the auxiliary programs
`mips-tdump.c' and `mips-tfile.c' can't be compiled on anything
but a Mips. It does work to cross compile for a Mips if you use
the GNU assembler and linker.
* Cross-compilers between machines with different floating point
formats have not all been made to work. GNU CC now has a floating
point emulator with which these can work, but each target machine
description needs to be updated to take advantage of it.
* Cross-compilation between machines of different word sizes is
somewhat problematic and sometimes does not work.
Since GNU CC generates assembler code, you probably need a
cross-assembler that GNU CC can run, in order to produce object files.
If you want to link on other than the target machine, you need a
cross-linker as well. You also need header files and libraries suitable
for the target machine that you can install on the host machine.
