[Mesa-dev] [PATCH 27/34] glsl: Make sure that we don't put too many bitfields in ast_type_qualifier.

[Paul Berry]

From: Eric Anholt <eric at anholt.net>

We do some tests of qualifiers using a union containing an int and the
struct full of bitfields, so make sure the bitfields don't spill
outside the int.
