NAME
as - assembler
SYNOPSIS
as [ option ... ] [ name ... ]
DESCRIPTION
As assembles the named files, or the standard input if no
file name is specified. The options are:
-dn Specifies the number of bytes n (1, 2, or 4) to be
assembled for offsets which involve forward or external
references, and which have sizes unspecified in the
assembly language. Default is -d4.
-L Save defined labels that begin with `L', which are nor-
mally discarded to save space in the resultant symbol
table. The compilers generate such temporary labels.
-V Use virtual memory for intermediate storage, rather
than a temporary file.
-W Do not complain about errors.
-J Use long branches to resolve jumps when byte-
displacement branches are insufficient. This must be
used when a compiler-generated assembly contains
branches of more than 32K bytes.
-R Make initialized data segments read-only, by concate-
nating them to the text segments. This obviates the
need to run editor scripts on assembly code to make
initialized data read-only and shared.
-t Specifies a directory to receive the temporary file,
other than the default
-oobj
Place output in file obj. Default is
All undefined symbols in the assembly are treated as global.
FILES
default temporary file

BUGS
-J should be eliminated; the assembler should automatically
choose among byte, word and long branches.
