When building a module, use the macro definitions on the command line as part of the hash rather than ignoring them. This means we'll end up building more module variants (overall), but it allows configuration macros such as NDEBUG to work so long as they're specified via command line. More to come in this space. llvm-svn: 142187 2011-10-17 14:55:37 +00:00			`// RUN: rm -rf %t`
[modules] Simplify -cc1 interface for enabling implicit module maps. We used to have a flag to enable module maps, and two more flags to enable implicit module maps. This is all redundant; we don't need any flag for enabling module maps in the abstract, and we don't usually have -fno- flags for -cc1. We now have just a single flag, -fimplicit-module-maps, that enables implicitly searching the file system for module map files and loading them. The driver interface is unchanged for now. We should probably rename -fmodule-maps to -fimplicit-module-maps at some point. llvm-svn: 239789 2015-06-16 00:08:24 +00:00			`// RUN: %clang_cc1 -fmodules -fimplicit-module-maps -fmodules-cache-path=%t -F %S/Inputs -DFOO_RETURNS_INT_PTR -verify %s`

Prior to adding the new "expected-no-diagnostics" directive to VerifyDiagnosticConsumer, make the necessary adjustment to 580 test-cases which will henceforth require this new directive. llvm-svn: 166280 2012-10-19 12:44:48 +00:00			`// expected-no-diagnostics`

Use @import rather than @__experimental_modules_import, since the latter is rather a mess to type. llvm-svn: 169919 2012-12-11 22:11:52 +00:00			`@import CmdLine;`
