Hi all,
In order to identify architectures I need to find a uniq id for every
possibilities (for pkgng)
here is the identification I propose:
arch-class-os-majorversion(-archi_specific_extension)
arch can be one of the following:
- x86 for i386 and amd64 (discussed with kib)
- powerpc for powerpc and powerpc64
- arm
- mips
- sparc
class may be:
- 32 bits
- 64 bits
os will always be freebsd :) (lower case)
majorversion the freebsd major version (10 9 8)
achi_specific_extension currently only mips and arm are concerned,
for arm could be:
el_oabi
eb_oabi
el_eabi
eb_eabi
One brief comment here: the output of uname -p (arm, armeb, etc.) is
meant to encode the ABI completely. All platforms with the same uname -p
should be able to execute each other's binaries. Why not just a sequence
of `uname -p`-`uname -s`-`uname -r` (or some subset of uname -r)? That
should be enough to completely encode compatibility information on
almost any operating system.
