The transition of libasan on darwin from using mach_override to the
replacement mac function
imposition code results in a non-functional static libasan (PR55599). The
method now used needs a
dynamic shared library and retaining a static libasan would require restoring
the deprecated
and unsupported mach_override code. The attached patch sets enable_static=no
for darwin
in libsanitizer/configure.ac and removes the static libasan support in
gcc/config/darwin.h.
Bootstrap and regression tested with asan.exp on x86_64-apple-darwin12. Okay
for gcc
trunk?
