-Update 6809/const.h.
-
-Produce bsd symbol tables.
-
-Accept gas format.
-
-Decide how to choose between 8-bit and 32-bit branches. 16-bit branches in
-32-bit mode are unusable because top 16 bits of PC are messed up.
-
-Buffer for printing of listing.
-
-Need to make assembler remember the code it generated in the penultimate
-pass and regenerate code of exactly the same length in the last pass.

-as options
-----------
-
-as [-03agjuw] [-b [bin]] [-lm [list]] [-n name] [-o obj] [-s sym] src
-
-The 6809 version does not support -0, -3, -a or -j.
-
-The 'src' file can be '-' for stdin but ONLY on 'big' machines.
-
-defaults (off or none except for these; no output is produced without a flag):
--03 native
-list stdout (beware of clobbering next arg)
-name basename of the source name
-
--0 start with 16-bit code segment
--3 start with 32-bit code segment
--a enable partial compatibility with asld
--g only put global symbols in object or symbol file
--j force all jumps to be long
--l produce list file, filename may follow
--m print macro expansions in listing
--n name of module follows (goes in object instead of source name)
--o produce object file, filename follows
--b produce a raw binary file, filename may follow
--s produce an ASCII symbol file, filename follows
--u take undefined symbols as imported-with-unspecified segment
--w don't print warnings
-
-The -u and -w options are perhaps back to front because they are needed for
-cc1 output and Minix's make does the wrong thing with .s files left around.
-However, all assembler code not written by compilers should assemble with
-them turned off.
-
-The -b flag produces a 'raw' binary file with no header, if there's no
--s flag the file starts at location 0. The -s generates an ASCII symbol
-table, if a binary file doesn't start at location zero the first two items
-are the start and end addresses of the binary file.
-
-BCC is classed as a 'small' compiler, with this there is a maximum line
-length of 256 characters.
-
-Using GASP
-----------
-
-The Gnu assembler preprocessor provides some reasonable implementations
-of user biased pseudo operations.
-
-It can be invoked as:
- gasp [-a] ... file.s [file2.s ...] | as86 [...] - [-o obj] [-b bin]
-
-Notes:
-Gasp generates an error for '.org' commands if you're not using
-'alternate' syntax you can use 'org' instead, otherwise use 'block'.
-
-Export is translated in .global, if you are making a 'bin' file use
-'public' or '.define' instead.
-
-The GASP list options have no support in as86.
