Comment:

 Universal (i386, x86_64, ppc) succeeded, BUT :

 {{{
 libtool: compile:  /usr/bin/gcc-4.2 -DHAVE_CONFIG_H -I. -I..
 -I/opt/local/include -Wall -I.. -DORC_ENABLE_UNSTABLE_API -pipe -O2
 -Xarch_i386 -O1 -Xarch_x86_64 -O3 -arch ppc -c orcpowerpc.c  -fno-common
 -DPIC -o .libs/liborc_0.4_la-orcpowerpc.o
 {standard input}:176:Parameter error: r0 not allowed for parameter 1 (code
 as 0 not r0)
 }}}

 This failure led me to search. After some attempts inspired from
 [http://gcc.gnu.org/onlinedocs/gcc/Machine-Constraints.html#Machine-
 Constraints],
 I got a successfully compiled universal orc. So, this
 {{{
 __asm__ __volatile__ ("dcbst %0,%1" :: "r" (ptr), "r" (i));
 }}}
 became
 {{{
 __asm__ __volatile__ ("dcbst %0,%1" :: "b" (ptr), "r" (i));
 }}}

 I'm waiting for any PowerPC expert to shout on me. ;}


 I also looked into the weird "i386 -O2" error... Wouldn't it be a bug in
 Apple's gcc ? Does this make sense to someone ?
 {{{

 }}}
