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!
