Not at the moment. The build was done with the --with-arch=2.0 to
check 32-bit PA2.0 code generation. I don't usually configure with
this option.
I note the test uses __builtin_return_address (1). This may not behave
correctly.
The test didn't fail on hppa-linux with --with-arch=2.0. However, there
are differences in call stubs. This is what makes
__builtin_return_address
difficult.
Needs some debugging.
