Thanks Joachim, Jani and Karel,
Very helpful :)
I managed to get access to a Fedora armv7hl box,
and running "ghc -v" there on an offending file I saw the argument to llc was:
llc -O3 -relocation-model=static /tmp/ghc3749_0/ghc3749_0.bc -o
which is not the expected one: -mattr=+v7,+vfp3,+d16 [-float-abi=hard].
ie the patched line is not the one getting applied...
(It seems to me it would be better to fix llvm though? Maybe it is
Anyway sorry <blush/> it seems the reason for the above is that I
forget to run aclocal! :-(
Not sure if +d16 is actually essential on Fedora though guess it doesn't hurt.
Karel, I will try to test your patch later.
