as

Portable GNU assembler. Primarily intended to assemble output from gcc to be used by ld.

• Assemble a file, writing the output to a.out:

as {{file.s}}

• Assemble the output to a given file:

as {{file.s}} -o {{out.o}}

• Generate output faster by skipping whitespace and comment preprocessing. (Should only be used for trusted compilers):

as -f {{file.s}}

• Include a given path to the list of directories to search for files specified in .include directives:

as -I {{path/to/directory}} {{file.s}}
