Subject: [TUHS] Design of the AT&T assembly syntax
Date: Mon, 28 Oct 2019 21:14:08 +0100 [thread overview]
Message-ID: <20191028201408.GA37167@fuz.su> (raw)
Some time ago, I wrote a piece [1] about the design of the AT&T
assembler syntax. While I'm still not quite sure if everything in there
is correct, this explanation seemed plausible to me; the PDP-11
assembler being adapted for the 8086, then the 80386 and then ELF
targets, giving us today's convoluted syntax.
The one thing in this chain I have never found is an AT&T style
assembler for x86 before ELF was introduced. Supposedly, it would get
away without % as a register prefix, thus being much less obnoxious to
use. Any idea if such an assembler ever existed and if yes where?
I suppose Xenix might have shipped something like that.
The only AT&T syntax assemblers I know today are those from Solaris,
the GNU project, the LLVM project, and possibly whatever macOS ships.
Are there (or where there) any other x86 AT&T assemblers? Who was
the first party to introduce this?
Yours,
Robert Clausecker
