From: Serge Pavlov Date: Thu, 3 Nov 2016 07:32:02 +0000 (+0000) Subject: Enhancement to test for -ast-print X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=516761b09f4c93f8d5498f23f2c4583cb8d857bb;p=clang Enhancement to test for -ast-print Present tests for the functionality provided by command lime option `-ast-print` check only absence of crash. This change tries to make testing better, - the output produced by the compiler is compiled again with option `-print-ast` and both outputs are compared. Such test at least checks that the output is valid code. This change fixes only the test for pure C. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@285882 91177308-0d34-0410-b5e6-96231b3b80d8 --- diff --git a/test/Coverage/ast-printing.c b/test/Coverage/ast-printing.c index ecaf3abeaa..eb22f92e66 100644 --- a/test/Coverage/ast-printing.c +++ b/test/Coverage/ast-printing.c @@ -1,5 +1,7 @@ // RUN: %clang_cc1 -fsyntax-only %s -// RUN: %clang_cc1 -ast-print %s +// RUN: %clang_cc1 -ast-print %s -o %t.1.c +// RUN: %clang_cc1 -ast-print %t.1.c -o %t.2.c +// RUN: diff %t.1.c %t.2.c // RUN: %clang_cc1 -ast-dump %s // RUN: %clang_cc1 -print-decl-contexts %s
