[committed] Fix OpenMP ICE on invalid during gimplification (PR c/47963)

[Jakub Jelinek]

Hi!

omp_notice_variable isn't prepared to see INTEGER_CST (which wouldn't be
there on valid code where DECL_SIZE is a DECL).
Fixed thusly, bootstrapped/regtested on x86_64-linux and i686-linux,
committed to trunk.

2011-03-03  Jakub Jelinek  <jakub@redhat.com>

	PR c/47963
	* gimplify.c (omp_add_variable): Only call omp_notice_variable
	on TYPE_SIZE_UNIT if it is a DECL.

	* gcc.dg/gomp/pr47963.c: New test.
	* g++.dg/gomp/pr47963.C: New test.
