[modules] Driver support for precompiling a collection of files as a single action. llvm-svn: 342305
2018-09-15 09:21:16 +08:00
// Check compiling a header module to a .pcm file.
//
// RUN: %clang -fmodules-ts -fmodule-name=foobar -x c++-header --precompile %S/Inputs/header1.h %S/Inputs/header2.h %S/Inputs/header3.h -o %t.pcm -v 2>&1 | FileCheck %s --check-prefix=CHECK-PRECOMPILE
//
// CHECK-PRECOMPILE: -cc1 {{.*}} -emit-header-module
// CHECK-PRECOMPILE-SAME: -fmodules-ts
// CHECK-PRECOMPILE-SAME: -fno-implicit-modules
// CHECK-PRECOMPILE-SAME: -fmodule-name=foobar
// CHECK-PRECOMPILE-SAME: -o {{.*}}.pcm
Reapply "Fix regression in behavior of clang -x c++-header -fmodule-name=XXX" This reverts commit r345963. We have a path forward now. Original commit message: The driver accidentally stopped passing the input filenames on to -cc1 in this mode due to confusion over what action was being requested. This change also fixes a couple of crashes I encountered when passing multiple files to such a -cc1 invocation. llvm-svn: 346130
