Richard Smith	ec4ad5ac9b	[modules] Make sure we make hidden UsingShadowDecls visible to redeclaration ... lookup for the UsingShadowDecls themselves. llvm-svn: 247714	2015-09-15 18:51:56 +00:00
Richard Smith	f091e129db	[modules] A using-declaration doesn't introduce a new entity, just a new name ... for an existing entity, and as such a using-declaration doesn't need to conflict with a hidden entity (nor vice versa). llvm-svn: 247654	2015-09-15 01:28:55 +00:00
Richard Smith	47972afd10	[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
Richard Smith	fd8634a09d	Make UsingShadowDecls redeclarable. This fixes some visibility problems with ... modules. With this fixed, I no longer see any test regressions in the libc++ test suite when enabling a single-module module.map for libc++ (other than issues with my system headers). llvm-svn: 193219	2013-10-23 02:17:46 +00:00
