FASM is a fast assembly language compiler for the x86 architecture processors, which does multiple passes to optimize the size of generated machine code. It is self-compilable and versions for different operating systems are provided. All the versions are designed to be used from the system command line and they should not differ in behavior. This program is written by Tomasz Grysztar.
Actually 2 different assembly exist, the most famous and old one FASM, and the new one FASMG.
To install dev-lang/fasm-bin or dev-lang/fasmg-bin, add the fulgurance-overlay repository.
Using eselect repository:
eselect repository add fulgurance-overlay git https://github.com/Fulgurance/fulgurance-overlay.git
To get information about optional settings after compilation, just type this command in a terminal:
flat assembler version 1.73.16 usage: fasm <source> [output] optional settings: -m <limit> set the limit in kilobytes for the available memory -p <limit> set the maximum allowed number of passes -d <name>=<value> define symbolic variable -s <file> dump symbolic information for debugging
flat assembler version g.jmhx
Usage: fasmg source [output]
-p limit Set the maximum allowed number of passes (default 100)
-e limit Set the maximum number of displayed errors (default 1)
-r limit Set the maximum depth of stack (default 10000)
-v flag Enable or disable showing all lines from the stack (default 0)
-i command Insert instruction at the beginning of source
