DESCRIPTION
The fbe command creates object files from assembly language
source files.
COMMON OPTIONS
The following flags are common to both SPARC and x86. They
may be specified in any order: type is either an 'x' indi-
cating the original
assembler or an 'a' indicating the a assembler.
-Dname
-Dname=def When the -P option is in effect, these
options are passed to the cpp(1) preprocessor
without interpretation by the as command;
otherwise, they are ignored.
-Ipath When the -P option is in effect, this option
is passed to the cpp(1) preprocessor without
interpretation by the as command; otherwise,
it is ignored.
-m Run the m4(1) macro processor on the input to
the assembler.
-n Suppress all the warnings while assembling.
-o outfile Put the output of the assembly in outfile.
By default, the output file name is formed by
removing the .s suffix, if there is one, from
the input file name and appending a .o suf-
fix.
-P Run cpp(1), the C preprocessor, on the files
being assembled. The preprocessor is run
separately on each input file, not on their
concatenation. The preprocessor output is
passed to the assembler.
-Qy|n If the n option is specified, it produces the
"assembler version" information in the com-
ment section of the output object file. If
the y option is specified, the information is
suppressed.
-s Place all stabs in the .stabs section. By
default, stabs ares placed in stabs.excl sec-
tions, which are stripped out by the static
linker, ld(1), during final execution. When
the -s option is used, stabs remain in the
final executable because .stab sections are
not stripped by the static linker.
-Uname When the -P option is in effect, this option
is passed to the cpp(1) preprocessor without
interpretation by the as command; otherwise,
it is ignored.
-V Write the version number of the assembler
being run on the standard error output.
SPARC Options
-b Generate extra symbol table information for
the Sun SourceBrowser.
-K PIC Generate position-independent code. The x86
assembler does not support the -K PIC flag.
-L Save all symbols, including temporary labels
that are normally discarded to save space, in
the ELF symbol table.
-q Perform a quick assembly. When the -q option
is used, many error checks are not performed.
Note: This option disables many error checks.
It is recommended that you do not use this
option to assemble handwritten assembly
language.
-S[a|C] Produce a disassembly of the emitted code to
the standard output.
o Adding the character a to the option
appends a comment line to each assembly code
which indicates its relative address in its
own section.
o Adding the character C to the option
prevents comment lines from appearing in the
output.
-T This is a migration option for 4.x assembly
files to be assembled on 5.x systems. With
this option, the symbol names in 4.x assembly
files will be interpreted as 5.x symbol
names.
-xarch=v7 This option instructs the assembler to accept
instructions defined in the SPARC version 7
(V7) architecture. The resulting object code
is in ELF format.
-xarch=v8 This option instructs the assembler to accept
instructions defined in the SPARC-V8 archi-
tecture, less the quad-precision floating-
point instructions. The resulting object code
is in ELF format.
-xarch=v8a This option instructs the assembler to accept
instructions defined in the SPARC-V8 archi-
tecture, less the quad-precision floating-
point instructions and less the fsmuld
instruction. The resulting object code is in
ELF format. This is the default choice of the
-xarch= options.
-xarch=v8plus This option instructs the assembler to accept
instructions defined in the SPARC-V9 archi-
tecture, less the quad-precision floating-
point instructions. The resulting object
code is in ELF format. It will not execute
on a Solaris V8 system (a machine with a V8
processor). It will execute on a Solaris V8+
system.
-xarch=v8plusa This option instructs the assembler to accept
instructions defined in the SPARC-V9 archi-
tecture, less the quad-precision floating-
point instructions, plus the instructions in
the Visual Instruction Set (VIS). The
resulting object code is in V8+ ELF format.
It will not execute on a Solaris V8 system (a
machine with a V8 processor). It will exe-
cute on a Solaris V8+ system
-xF Generates additional information for perfor-
mance analysis of the executable using SPARC-
works analyzer. If the input file does not
contain any stabs (debugging directives),
then the assembler will generate some default
stabs which are needed by the SPARCworks
analyzer. Also see the manual page dbx.
ENVIRONMENT
TMPDIR
as normally creates temporary files in the directory /tmp.
You may specify another directory by setting the environ-
ment variable TMPDIR to your chosen directory. (If TMPDIR
isn't a valid directory, then as will use /tmp).
FILES
By default, as creates its temporary files in /tmp.

NOTES
If the -m (invoke the m4(1) macro processor) option is used,
keywords for m4(1) cannot be used as symbols (variables,
functions, labels) in the input file since m4(1) cannot
determine which keywords are assembler symbols and which
keywords are real m4(1) macros.
Whenever possible, you should access the assembler through a
compilation system interface program such as cc(1B).
All undefined symbols are treated as global.
