Subject: [Caml-list] ocaml/amd64 native compiler on openbsd
Date: Sat, 6 Mar 2004 17:37:44 +0000 [thread overview]
Message-ID: <20040306173744.GA31003@quick.recoil.org> (raw)
I've committed support into OpenBSD ports for the ocaml/amd64 native
compiler. It will be available in OpenBSD 3.5.
The configure patch at the end of the msg is required to detect the
OpenBSD architectures. Also, OpenBSD uses BSD nm, and not the binutils
one, but it appears to work fine with ocamlopt, so the test for that is
modified as well.
The only other issue is that the version of gas used in OpenBSD doesnt
support the mergeable section flag, so I just removed it from the assembly
output, without any ill-effects as far as I can tell.
.section .rodata.cst8,"aM",@progbits,8 becomes
.section .rodata.cst8,"a",@progbits
The exceptions fix from ocaml-current was also needed.
