> Hi everyone,
> I've updated our bgclang install on vesta and mira to r220548-20141024.
> This new build picks up some nice upstream improvements and bug fixes and some local improvements and fixes.
>  - support for __attribute__((align_value(n))) and #pragma omp simd aligned(n) for specifying pointer alignments
>  - better support for QPX vectorization of math functions with -ffast-math is enabled (also, this build uses the scalar SLEEF functions for exp/exp2/exp10 by default because they're much faster than the libm versions).
>  - bgclang++11 includes a work-around for std::locale("") being broken (because libc's newlocale is broken when provided with "") -- hopefully boost.filesystem will work better now.
>  - A work-around (via a wrapper header) is provided for spi/include/kernel/process.h so you shouldn't need to worry about the missing __INLINE__ on Kernel_GetJobID in the system header any more.

Thanks for the work-around.

> For those maintaining their own installs, RPMs (and SRPMs) are available on the trac page: https://trac.alcf.anl.gov/projects/llvm-bgq
> Thanks again,
