Fix the location we emit the "not a constant" error for this: int foo() { typedef int x[foo()]; static int y = sizeof(x); } previously we'd emit it on the typedef, which made not sense at all. llvm-svn: 45154 2007-12-18 15:15:40 +08:00			`// RUN: clang %s -verify -fsyntax-only`

wrap some long diagnostics, make 'initializer is not a constant' diagnostic a bit more clear (rdar://5646070) llvm-svn: 54606 2008-08-10 09:58:45 +08:00			`static int y = sizeof(x); // expected-error {{not a compile-time constant}}`

PR2347: Fix crash iterating over VLAs; this started triggering because we now iterate over the whole AST when we destroy it. llvm-svn: 51363 2008-05-21 13:06:46 +08:00			`// PR2347`

Fix this test so that it's valid; the point is to test for the crash, not the missing diagnostic. llvm-svn: 51365 2008-05-21 13:37:55 +08:00			`int e[2][m];`
