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 spec‐
ified in any order.
-b Generates extra symbol table information for the Source‐
Browser.
-Dname
-Dname=def When the -P option is in effect, these options are passed
to the cpp(1) preprocessor without interpretation by the
fbe 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 fbe
command; otherwise, it is ignored.
-i Instructs fbe to ignore line-number information from the
preprocessor.
-m Run the m4(1) macro processor on the input to the assem‐
bler.
-m32|-m64 Generate 32-bit or 64-bit ELF format object code.
-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
suffix.
-P Run cpp(1), the C preprocessor, on the files being assem‐
bled. 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 comment 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 sections, 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.
-Y Specify directory for m4 and/or cm4def
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 nor‐
mally 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 rec‐
ommended that you do not use this option to assemble hand‐
written assembly language.
-S[a|C] Produce a disassembly of the emitted code to the standard
output.
· Adding the character a to the option appends a comment
line to each assembly code which indicates its relative
address in its own section.
· 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=v8a Enables the assembler to accept instructions defined in
the SPARC-V8 architecture, less the fsmuld instruction.
The resulting object code is in ELF32 format when compiled
with -m32, ELF64 format with -m64. This is the default
choice of the -xarch= options.
-xarch=sparc Enables the assembler to accept instructions defined in
the SPARC-V9 architecture. The resulting object code is
in ELF32 format when compiled with -m32, ELF64 format with
-m64. It will not execute on a Solaris V8 system (a
machine with a V8 processor). It will execute on a
Solaris V8+ system.
-xarch=sparcvis
Enables the assembler to accept instructions defined in
the SPARC-V9 architecture plus the instructions in the
Visual Instruction Set (VIS) version 1.0. The resulting
object code is in V8+ ELF32 format when compiled with
-m32, ELF64 format with -m64. It will not execute on a
Solaris system with a processor. It will execute on a
Solaris system with a V8+ processor.
-xarch=sparcvis2
Enables the assembler to accept instructions defined in
the SPARC-V9 architecture, plus the instructions in the
Visual Instruction Set (VIS) version 2.0, with UltraSPARC-
III extensions. The resulting object code is in V8+ ELF32
format when compiled with -m32, ELF64 format with -m64.
-xarch=sparcfmaf
Accept instructions defined for the sparcfmaf version of
the SPARC-V9 ISA, plus the UltraSPARC extensions, includ‐
ing the Visual Instruction Set (VIS) version 1.0, the
UltraSPARC-III extensions, including the Visual Instruc‐
tion Set (VIS) version 2.0, and the SPARC64 VI extensions
for floating-point multiply-add.
-xarch=sparcima
Accept instructions defined for the sparcima version of
the SPARC-V9 ISA, plus the UltraSPARC extensions, includ‐
ing the Visual Instruction Set (VIS) version 1.0, the
UltraSPARC-III extensions, including the Visual Instruc‐
tion Set (VIS) version 2.0, SPARC64 VI extensions for
floating-point multiply-add, and the SPARC64 VII exten‐
sions for integer multiply-add.
-xF Generates additional information for performance analysis
of the executable using SPARCworks 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 man‐
ual page dbx.
x86 Options
-nH Suppress the generation of the Hardware Capabilities sec‐
tion
ENVIRONMENT
TMPDIR
as normally creates temporary files in the directory /tmp. You may
specify another directory by setting the environment 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.

nam(3S), a.out(4)NOTES
On SPARC, the cpp symbol __sparc is set when the flag -P appears, as
well as __sparcv8 with the -m32 flag, and __sparcv9 with the -m64 flag.
On x86/x64, the symbol __i386 is set when the flag -P appears, as well
as __amd64 with the -m64 flag.
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 assem‐
bler symbols and which keywords are real m4(1) macros.
Whenever possible, you should access the assembler through a compila‐
tion system interface program such as cc(1B).
All undefined symbols are treated as global.
