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
