* Wrap clang modules and pch files in an object file container.Adrian Prantl2015-07-071-0/+1
| | | | | | | | | | | | | This patch adds ObjectFilePCHContainerOperations uses the LLVM backend to put the contents of a PCH into a __clangast section inside a COFF, ELF, or Mach-O object file container. This is done to facilitate module debugging by makeing it possible to store the debug info for the types defined by a module alongside the AST. rdar://problem/20091852 llvm-svn: 241620
* [modules] Simplify -cc1 interface for enabling implicit module maps.Richard Smith2015-06-161-4/+4
| | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | This is a necessary prerequisite for debugging with modules. The .pcm files become containers that hold the serialized AST which allows us to store debug information in the module file that can be shared by all object files that were built importing the module. This reapplies r230044 with a fixed configure+make build and updated dependencies and testcase requirements. Over the last iteration this version adds - missing target requirements for testcases that specify an x86 triple, - a missing clangCodeGen.a dependency to libClang.a in the make build. rdar://problem/19104245 llvm-svn: 230423
* Move the initialization of VAListTagName after InitializeSema()Ben Langmuir2014-09-051-0/+27
This innocuous statement to get the identifier info for __va_list_tag was causing an assertion failure: NextIsPrevious() && "decl became non-canonical unexpectedly" if the __va_list_tag identifier was found in a PCH in some circumstances, because it was looked up before the ASTReader had a Sema object to use to find existing decls to merge with. We could possibly move getting the identifier info even later, or make it lazy if we wanted to, but this seemed like the minimal change. Now why a PCH would have this identifier in the first place is a bit mysterious. This seems to be related to the global module index in some way, because when the test case is built without the global module index it will not emit an identifier for __va_list_tag into the PCH, but with the global module index it does. llvm-svn: 217275
