Flat Assembler 1.67.29 (Default branch)
11-16-2008
The flat assembler is a fast and efficient self-assembling 80x86 assembler for DOS, Windows, and Linux operating systems. It supports all 8086-80486/Pentium instructions with MMX, SSE, SSE2, SSE3, and 3DNow! extensions and x86-64 (both AMD64 and EM64T) instructions. It can produce output in binary, MZ, PE, COFF, or ELF format. It includes the powerful but easy-to-use macroinstruction support, and does multiple passes to optimize the instruction codes for size. The flat assembler is entirely written in assembly language. License: BSD License (revised) Changes:|

as_ia(1) General Commands Manual as_ia(1) NAME
as_ia: as - assembler for Integrity systems SYNOPSIS
outfile] [file] Remarks This manpage describes on Integrity systems. For on PA-RISC systems, see as_pa(1). DESCRIPTION
assembles the named source file file, or the standard input if file is not specified. The output of the assembler is an ELF relocatable object file that must be processed by before it can be executed. Assembler output is stored in file outfile. If the option is not specified, the assembler constructs a default name. If no source file is specified, outfile will be otherwise the suffix (if present) is stripped from the name of the source file and is appended to it. Any directory names are removed from the name so that the object file is always written to the current directory. does not not perform any macro processing. Standard C preprocessor constructs can be used if the assembler is invoked through the C com- piler. Options recognizes the following options: Specify that the source file contains 32-bit ABI targeted code. This option is overridden by the assembler directive in the source file. The object file is a 32-bit ELF file by default. Specify that the source file contains 64-bit ABI targeted code. This option is overridden by the assembler directive in the source file. The object file is a 64-bit ELF file by default. Permit an unlimited number of errors to be tolerated before the assembly process is abandoned. By default, one hundred errors are allowed before the assembler aborts. Specify that the object file should be 32-bit ELF. This is the default (see also Note that it is valid to write 64-bit ABI targeted code to a 32-bit ELF file. All 32-bit addresses in the object file are zero-extended to 64-bit upon loading. Zero-extension, however, may invalidate any negative addresses (such as with relocations). Specify that the object file should be 64-bit ELF (see also See See Set dependency checking. lvl must be one of the following: or what must be one of the following: or Produce an output object file with the name outfile instead of constructing a default name. Print the version information to stderr before assembling the input. Suppress the specified warning messages. Promote the specified warning messages to errors. Suppress all warning messages. EXTERNAL INFLUENCES
Environment Variables determines the location of the message catalog for the processing of controls which assembler to invoke and enables support for multiple (cross-) development kits. The variable points to the root of a spe- cific SDK. No provision has been made to validate the value of the variable or the suitability of the assembler that's being invoked. International Code Set Support Single- and multi-byte character code sets are supported. WARNINGS
The assembler does not check dependencies. DIAGNOSTICS
When syntactic or semantic errors occur, a single-line diagnostic is displayed on standard error, together with the line number and the file name in which it occurred. FILES
