It just so happens that I'm digging into my patch once more. I tried
Oh, good :-)
implementing your suggested modifications. A couple of questions arose:
gcc on Mac OS X/darwin offers the Apple-only -arch option.
" -arch arch Compile for the specified target architecture arch. The allowable [...] "
This option is separate from the -march option: -arch and -march are two separate compiler flags, the latter with established bjam/gcc usage. That is, if I replace my <arch> feature with an (enahnced) <architecture> feature from builtin.jam, the existing gcc options involving -march are eclipsed. The same holds for <address-model>. For example, <address-model>32 maps to -m32 under 'normal' gcc, whereas I would commandeer <architecture>power/<address-model>32, emitting -arch ppc instead. Is this what you want?
If that's what works for the Apple GCC... Yes. -- -- Grafik - Don't Assume Anything -- Redshift Software, Inc. - http://redshift-software.com -- rrivera/acm.org - grafik/redshift-software.com -- 102708583/icq - grafikrobot/aim - grafikrobot/yahoo
