- This directory contains the necessary files to port the C compiler
- ``LCC'' (available by FTP from sunsite.doc.ic.ac.uk in the directory
- /computing/programming/languages/c/lcc) to compile for Linux (a.out
- or ELF) by using NASM as a back-end code generator.
- This patch has been tested on lcc version 3.6.
- To install:
- - Copy `x86nasm.md' into the `src' directory of the lcc tree.
- - Copy either `lin-elf.c' or `lin-aout.c' into the `etc' directory.
- - If you're installing for a.out, edit `x86nasm.md' and change the
- conditional after the comment reading "CHANGE THIS FOR a.out" in
- the `defsymbol' function from `#if 0' to `#if 1'.
- - Make the following changes to `bind.c' in the `src' directory:
- - Near the top of the file, add a line that reads
- extern Interface x86nasmIR;
- - In the `bindings' array, add the lines
- "x86-nasm", &x86nasmIR,
- "x86/nasm", &x86nasmIR,
- (in sensible looking places...)
- A sample `bind.c' has been provided to show what the result of
- this might look like. You might be able to get away with using it
- directly...
- - Modify the lcc makefile to include rules for x86nasm.o: this will
- have to be done in about three places. Just copy any line with
- `x86' on it and modify it to read `x86nasm' everywhere. (Except
- that in the list of object files that rcc is made up from, do
- remember to ensure that every line but the last has a trailing
- backslash...)
- - You may have to modify the contents of `lin-elf.c' or `lin-aout.c'
- to reflect the true locations of files such as crt0.o, crt1.o,
- ld-linux.so and so forth. If you don't know where to find these,
- compile a short C program with `gcc -v' and see what command line
- gcc feeds to `ld'.
- - You should now be able to build lcc, using `lin-elf.c' or
- `lin-aout.c' as the system-dependent part of the `lcc' wrapper
- program.
- - Symlink x86nasm.c into the `src' directory before attempting the
- triple test, or the compile will fail.
- - Now it should pass the triple test, on either ELF or a.out. Voila!
