[opensuse-programming] GAS
I have been writing some routines in assembler using nasm & ld (compile and link) and gdb for debuggin. I am going to be converting these routines to the at&t syntax and pass them off to gcc(gas) so that I will have access to libc. I have been reading about the gcc compiler, and have been examining its .s files (at&t syntax) which are fed to GAS. GAS is supposed to ship with binutils, but I do not find it on my system as a separate utility... I use gcc every day so obviously gas is there somewhere. Can someone please tell me whether gcc still uses gas? ... is gas internal to gcc now? Also, I have read rumors that the latest gas code supports the intel syntax... true?

Just do a 'rpm -ql binutils' and you'll see if the binutils (ar, ld, gas, nm, objdump) have been installed.

Yes, it does so and will continue for the forseeable future :)

No.

True. But AFAIK you have to explicitly tell gas that you're using Intel syntax. Philipp --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-programming+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-programming+help@opensuse.org

Yes, binutils is installed and I can see: /usr/bin/ar /usr/bin/objdump /usr/bin/nm /usr/bin/ld but, there is no gas... anywhere on the system... however, gcc works just fine. I am running openSUSE 10.0. where is gas... can it be run at the cli ? -- Kind regards, M Harris <>< --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-programming+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-programming+help@opensuse.org

where is gas... can it be run at the cli ? ehem. Well, gas is actually.... drum roll.... "as"
So, now... the question is... is this an openSUSE thing? Does everyone else call it gas, and suse calls it ... as. Of course the assembler is called (man as) the Portable Assembler... so I suppose they could have called the executable "pas" well... pas, gas, or as.... the whole thing is really starting to sound funny now... seems like a brain fart after all. Anyway, I'm happily experimenting with "as" and thinking I should just stick with nasm. :-} -- Kind regards, M Harris <>< --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-programming+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-programming+help@opensuse.org
