|0004171||OCaml||-OCaml general||public||2006-11-27 19:12||2009-03-31 13:08|
|Target Version||Fixed in Version||3.11.0|
|Summary||0004171: configure should have an option to specify the assembler command and the host arch|
|Description||On Linux / x86_64, it is possible to have both 32-bit and 64-bit applications. 32-bit applications may sometimes be preferable (less memory is used, as experienced with Astrée).|
This simply requires building OCaml for a i686 target instead of an amd64 target. I've done it, and here are the issues I've noticed:
* there's no option to force arch to be i686-... instead of amd64-...; easy fix: the configure script should accept a -host command line option
* there's no option to specify the assembler that ocamlopt uses:
./asmcomp/i386/proc.ml: Ccomp.command ("as -o " ^ F
is hardwired. If one wants to compile in 32-bit mode on an x86_64 machine, one has to replace as by as -32 in that line.
Of course, seasoned programmers can patch OCaml's source by hand, but still...
|Tags||No tags attached.|
|This should also affect $(AS) and $(ASPP). Note that changing $(AS) does not affect the assembler that ocamlopt uses...|
configure does support the -host option. The ability to configure the assembler used by ocamlopt would be good, however. I keep this as a feature wish.
Tentative implementation in CVS trunk. To be tested on platforms other than Linux/x86_64.
