From: Serge Pavlov Date: Fri, 4 Nov 2016 06:09:23 +0000 (+0000) Subject: Enhancement to test for -ast-print X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=351cf00f4839eb42c9c4a247302a8c625d835d1f;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. This is recommit of r285882. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@285981 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
