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 %s -emit-llvm -o %t -fobjc-gc -fblocks -triple i386-apple-darwin10`
Eliminate &&s in tests. - 'for i in $(find . -type f); do sed -e 's#\(RUN:.[^ ]\) && *$#\1#g' $i \| FileUpdate $i; done', for the curious. llvm-svn: 86430 2009-11-08 09:45:36 +08:00			`// RUN: grep "objc_assign_strongCast" %t \| count 2`
Initialize Obj-C GC attributes when emitting BlockDeclRefExprs. - Otherwise we may incorrectly miss generation of some write barriers. llvm-svn: 72313 2009-05-23 10:49:02 +08:00
