Subject: Ignore MachO symbol flags in the upper nibble of n_desc.
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=fadfd7b9776c723357894af00442a35d0a4d0acf;p=oota-llvm.git

Ignore MachO symbol flags in the upper nibble of n_desc.

They don't impact the MCJIT rtdyld, so just mask them off for now.
