Building and Installing a Cross-Compiler

   GNU CC can function as a cross-compiler for many machines, but not

   * 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 has not
     really been addressed yet.

   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.

* Steps of Cross
Using a cross-compiler involves several steps that may be carried out on different machines.
* Configure Cross
Configuring a cross-compiler.
* Tools and Libraries
Where to put the linker and assembler, and the C library.
* Cross Headers
Finding and installing header files for a cross-compiler.
* Cross Runtime
Supplying arithmetic runtime routines (`libgcc1.a').
* Build Cross
Actually compiling the cross-compiler.
