as

Portable GNU assembler. Primarily intended to assemble output from gcc to be used by ld. More information: https://keith.github.io/xcode-man-pages/as.1.html.

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

as {{path/to/file.s}}

• Assemble the output to a given file:

as {{path/to/file.s}} -o {{path/to/output_file.o}}

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

as -f {{path/to/file.s}}

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

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