Hello

This is a version of gnu's gas which generates Amiga object code.  It
is robust enough to replace gas+sobja when compiling itself with gcc. 

I am willing to give it to the GCC Porting Project, under the usual
conditions of the Gnu license. 

It takes care of the fact that, under AmigaDos, all reloc32 are
absolute, and all reloc16 and reloc8 are relative: The code generation
(m68k.c) has been changed, and no longer generates long pc relative or
short absolute references. This will be useful for generating
PIC code with GCC2.0.

My address is

Leon Bottou
Avenue du Lot
48500 La Canourgue
France.







PS:
---

AGAS does not handle the COMMON block, unless someone tell me how
EXT_COMMON ( See 2.0 dos/doshunks.c! ) works. 

Question: How important is that?

If yes, and if it appears that EXT_COMMON is a false alert, I suggest
the following extension to the amiga object code:

#define EXT_GCC_COMMON 4

Write EXT_GCC_COMMON definitions in the EXT hunk of the BSS section.
Replace its address by the length of this common block.  This will not
disturb the usual object code analysis programs, like omd, disasm,
cnm, etc... 

Relocate references to common symbols with the usual EXT_REF32,
EXT_REF16, and EXT_REF8. 

This extension can be handled by a new linker, or by an external
program called before blink!  This program would append the common
variable to the BSS block of the first object file defining the common
variable. This is a one pass process.... 

This could be the option '-c'.


PS (AGAIN):
----------

One of the C files, (amiga-write.c) has a stub routine for writing the
DBX stab entries into the object file.  Could be useful if someone
decides to port GDB.  The best solution probably consists in writing
the stabs in BSD format within the DEBUG hunk.

This could be the option '-g'.



PS (3RD):
--------

No time to add options '-c' and '-g' now. 
In a few months, may be.
