PR 31797: An infinite loop in the compiler while building RTEMS.
Daniel, I see you've been commenting on this; are you working on the
fix? If so, do you have an ETA?
Why are you waiting for this one? RTEMS is not a primary or secondary
platform. So there is no reason to wait with the release because of
this PR, according to the release criteria (xf.
http://gcc.gnu.org/gcc-4.2/criteria.html).
I'm not particularly interested in it because of its RTEMS-ness.
Rather, I'm interested in it because it's a new case of the compiler
failing to correctly process valid code, not present in previous
versions of GCC. The test case is not RTEMS-specific; it's a problem
that looks like it could equally well apply to lots of other code out
there making use of volatile storage.
I thought Ralf had managed to reproduce the failure with the reduced
test case
on all targets he had tried. The code is in an RTEMS device driver but
since
it involves volatile, it is possible that this code occur in any OS or
device driver.
