Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'. - This is designed to make it obvious that %clang_cc1 is a "test variable" which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it can be useful to redefine what gets run as 'clang -cc1' (for example, to set a default target). llvm-svn: 91446 2009-12-16 04:14:24 +08:00			`// RUN: %clang_cc1 -fsyntax-only -verify %s`

Improve diagnostics when we fail to convert from a source type to a destination type for initialization, assignment, parameter-passing, etc. The main issue fixed here is that we used rather confusing wording for diagnostics such as t.c:2:9: warning: initializing 'char const [2]' discards qualifiers, expected 'char ' [-pedantic] char name = __func__; ^ ~~~~~~~~ We're not initializing a 'char const [2]', we're initializing a 'char ' with an expression of type 'char const [2]'. Similar problems existed for other diagnostics in this area, so I've normalized them all with more precise descriptive text to say what we're initializing/converting/assigning/etc. from and to. The warning for the code above is now: t.c:2:9: warning: initializing 'char ' from an expression of type 'char const [2]' discards qualifiers [-pedantic] char *name = __func__; ^ ~~~~~~~~ Fixes <rdar://problem/7447179>. llvm-svn: 100832 2010-04-09 08:35:39 +08:00			`obj = vv; // expected-error{{assigning to 'XX ' from incompatible type 'void '}}`
