From 0f99d6a4413e3da6ec242c0ab715d6699045dea8 Mon Sep 17 00:00:00 2001 From: Richard Smith Date: Sun, 9 Aug 2015 08:48:41 +0000 Subject: [modules] PR22534: Load files specified by -fmodule-file= eagerly. In particular, this avoids the need to re-parse module map files when using such a module. llvm-svn: 244416 --- clang/test/Modules/explicit-build-missing-files.cpp | 21 +++++++++++++++++++++ 1 file changed, 21 insertions(+) create mode 100644 clang/test/Modules/explicit-build-missing-files.cpp (limited to 'clang/test/Modules/explicit-build-missing-files.cpp') diff --git a/clang/test/Modules/explicit-build-missing-files.cpp b/clang/test/Modules/explicit-build-missing-files.cpp new file mode 100644 index 0000000..2ea157b --- /dev/null +++ b/clang/test/Modules/explicit-build-missing-files.cpp @@ -0,0 +1,21 @@ +// RUN: rm -rf %t +// RUN: mkdir %t +// RUN: echo 'extern int a;' > %t/a.h +// RUN: echo 'extern int b;' > %t/b.h +// RUN: echo 'module a { header "a.h" header "b.h" }' > %t/modulemap + +// We lazily check that the files referenced by an explicitly-specified .pcm +// file exist.
