Actually,
I got curious and checked it myself, and to my surprise the $31 had
disappeared , so i searched a bit and realized that I need to add escape
characters to $ because of m4, and so I did:
OMPI_GCC_INLINE_ASSIGN='"bis [$]31,[$]31,%0" : "=&r"(ret)'
both to alpha-*) and alphaev6-*)
but now, although configure reports that gcc supports inline
assembly:
checking if gcc supports GCC inline assembly... yes <----------
checking if gcc supports DEC inline assembly... no
checking if gcc supports XLC inline assembly... no
checking if g++ supports GCC inline assembly... yes <----------
it says that it cannot generate atomic operations, since it
lacks a
ALPHA.asm:
checking for pre-built assembly file... no (not in asm-data)
checking whether possible to generate assembly file... failed
configure: WARNING: Could not build atomic operations assembly file.
configure: WARNING: There will be no atomic operations for this build.
checking for atomic assembly filename... none
but it continues the configure process.
I start compiling and I get another error:
al_object.c -fPIC -DPIC -o class/.libs/opal_object.o

, but beware that I'm using the gcc flag '-save-temps' to check where
the
problem was:
make CFLAGS=-save-temps
so I started searching where that macro might come from and ended up in
opal/include/opal/sys/alpha/atomic.h
I took out the extra // comments in the asm code from
'opal_atomic_cmpset_32' and opal_atomic_cmpset_64' which seemed to
fix that
problem and restarted the compilation and after some more compiling it bombed
out in:
(...)
then mv -f "$depbase.Tpo" "$depbase.Plo"; else rm -f "$depbase.Tpo"; exit 1;

and here I got stuck :)
I send my config.log in the attachment, with just the bis [$]31
modification
