...build2. 11-tree_invariant.diff Backport recompute_tree_invariant_for_addr_expr from 4.3. 12-optimize.diff The Ada front-end makes use of the optimization level (-O1 etc), however the level is not available in gcc-llvm4. Pretend the optimization level is 2, until a better solution is found. 13-optabs.diff Remove all uses of optabs by Ada. These seem to be left-over from older gcc versions: while optabs are initialized, they are not actually used. 14-decl_rtl.diff Use the LLVM version of make_decl_rtl when compiling for LLVM. 15-gimplifier.diff Backport some gimplifier fixes from 4.3.

Yup, this is EXACTLY what is going on. I took this very simple C function: int Array[1000]; void test(int
