| | | | | | | | Unconditionally define __C99FEATURES__ when using C++ on Solaris. This is a (hopefully temporary) work around for libc++ exposing C99-but-not-C++98 features in C++98 mode. llvm-svn: 151889

* include clang's config.h unconditionally (v2)Dylan Noblesmith2012-02-141-4/+1
| | | | | | | | | | And remove HAVE_CLANG_CONFIG_H, now that the header is generated in the autoconf build, too. Reverts r149571/restores r149504, now that config.h is generated correctly by LLVM's configure in all build configurations. llvm-svn: 150487
* Basic: import SmallString<> into clang namespaceDylan Noblesmith2012-02-051-1/+1
| | | | | | | (I was going to fix the TODO about DenseMap too, but that would break self-host right now. See PR11922.) llvm-svn: 149799

| | | | | | | | | --with-gcc-toolchain that just uses the new toolchain probing logic. This fixes linking with -m32 on 64 bit systems (the /32 dir was not being added to the search). llvm-svn: 149652
* Back out my heinous hack that tricked the module generation mechanismDouglas Gregor2012-02-021-0/+8
| | | | | | | | | | | | | | | | | | | | into using non-absolute system includes (<foo>)... ... and introduce another hack that is simultaneously more heineous and more effective. We whitelist Clang-supplied headers that augment or override system headers (such as float.h, stdarg.h, and tgmath.h). For these headers, Clang does not provide a module mapping. Instead, a system-supplied module map can refer to these headers in a system module, and Clang will look both in its own include directory and wherever the system-supplied module map suggests, then adds either or both headers. The end result is that Clang-supplied headers get merged into the system-supplied module for the C standard library. As a drive-by, fix up a few dependencies in the _Builtin_instrinsics module. llvm-svn: 149611
* back out r149504Dylan Noblesmith2012-02-021-1/+4
| | | | | | Too many weird build failures. llvm-svn: 149571
* include clang's config.h unconditionallyDylan Noblesmith2012-02-011-5/+3
| | | | | | | | | | | | | And remove HAVE_CLANG_CONFIG_H, now that the header is generated in the autoconf build, too. (clang r149497 / llvm r149498) Also include the config.h header after all other headers, per the LLVM coding standards. It also turns out WindowsToolChain.cpp wasn't using the config header at all, so that include's just deleted now. llvm-svn: 149504

* Add a couple more GCC versions to C++ search paths for MinGW. Patch by ↵Eli Friedman2011-11-281-0/+2
| | | | | | | | Ruben Van Boxem. (We should probably start doing some sort of autodetection like we do on Linux at some point.) llvm-svn: 145326
* Move the Linux header searching from the Frontend to the Driver. This isChandler Carruth2011-11-051-274/+7
| | | | | | | | | | | | | | | | the first (and diff-noisiest) step to making Linux header searching tremendously more principled and less brittle. Note that this step should have essentially no functional impact. We still search the exact same set of paths in the exact same order. The only change here is where the code implementing such a search lives. This has one obvious negative impact -- we now pass a ludicrous number of flags to the CC1 layer. That should go away as I re-base this logic on the logic to detect a GCC installation. I want to do this in two phases so the bots can tell me if this step alone breaks something, and so that the diffs of the refactoring make more sense. llvm-svn: 143822
* Add two flags to the CC1 layer that I was hoping to avoid. We need toChandler Carruth2011-11-051-2/+2
| | | | | | | | | | | | | | | | | | | | encode the *exact* semantics which the header search paths internally built by the Frontend layer have had, which is both non-user-provided, and at times adding the implicit extern "C" bit to the directory entry. There are lots of CC1 options that are very close, but none do quite this, and they are all already overloaded for other purposes. In some senses this makes the command lines more clean as it clearly indicates which flags are exclusively used to implement internal detection of "standard" header search paths. Lots of the implementation of this is really crufty, due to the surrounding cruft. It doesn't seem worth investing lots of time cleaning this up as it isn't new, and hopefully *lots* of this code will melt away as header search inside of the frontend becomes increasingly trivial. llvm-svn: 143798
* Begin the migration of header search logic to the driver, starting withChandler Carruth2011-11-041-244/+16
| | | | | | | | | Windows. There are still FIXMEs and lots of problems with this code. Some of them will be addressed shortly by my follow-up patches, but most are going to wait until we isolate this code and can fix it properly. This version should be no worse than what we had before. llvm-svn: 143752

* Add "just one more" include path to the monstrosity that is our headerChandler Carruth2011-10-311-0/+1
| | | | | | | | | | | search logic. The Debian multiarch seems to have completely changed from when these were originally added, and I'd like to remove a bunch of them, but I'll be lazy and delay that until this logic is hoisted into the driver where it belongs. This should resolve PR11223. llvm-svn: 143345

| | | | llvm-svn: 140365
* Add support for CPATH and friends.Benjamin Kramer2011-09-221-36/+5
| | | | | | | | | | | | This moves the existing code for CPATH into the driver and adds the environment lookup and path splitting there. The paths are then passed down to cc1 with -I options (CPATH), added after the normal user-specified include dirs. Language specific paths are passed via -LANG-isystem and the actual filtering is performed in the frontend. I tried to match GCC's behavior as close as possible Fixes PR8971. llvm-svn: 140341

* Fix the default libc++ header search path to be sysrooted. Radar 9639692.Bob Wilson2011-06-211-2/+6
| | | | | | | | | The -cxx-isystem path is not prefixed with the sysroot directory, so it's not a good way for the driver to set the system default C++ search path. Instead, add -stdlib as a cc1 option and teach the frontend how to find the headers. The driver can then just pass -stdlib through to "cc1". llvm-svn: 133547
