New Revision: 281179<br>
<br>
URL: <a href="http://llvm.org/viewvc/llvm-project?rev=281179&view=rev" rel="noreferrer" target="_blank">http://llvm.org/viewvc/llvm-pr<wbr>oject?rev=281179&view=rev</a><br>
Log:<br>
[libcxx] Introduce an externally-threaded libc++ variant.<br>
<br>
This patch further decouples libc++ from pthread, allowing libc++ to be built<br>
against other threading systems. There are two main use cases:<br>
<br>
- Building libc++ against a thread library other than pthreads.<br>
<br>
- Building libc++ with an "external" thread API, allowing a separate library to<br>
provide the implementation of that API.<br>
<br>
The two use cases are quite similar, the second one being sligtly more<br>
de-coupled than the first. The cmake option LIBCXX_HAS_EXTERNAL_THREAD_API<br>
enables both kinds of builds. One needs to place an <__external_threading><br>
header file containing an implementation of the "libc++ thread API" declared<br>
in the <__threading_support> header.<br>
<br>
For the second use case, the implementation of the libc++ thread API can<br>
delegate to a custom "external" thread API where the implementation of this<br>
external API is provided in a seperate library. This mechanism allows toolchain<br>
vendors to distribute a build of libc++ with a custom thread-porting-layer API<br>
(which is the "external" API above), platform vendors (recipients of the<br>
toolchain/libc++) are then required to provide their implementation of this API<br>
to be linked with (end-user) C++ programs.<br>
<br>
Note that the second use case still requires establishing the basic types that<br>
get passed between the external thread library and the libc++ library<br>
(e.g. __libcpp_mutex_t). These cannot be opaque pointer types (libc++ sources<br>
won't compile otherwise). It should also be noted that the second use case can<br>
have a slight performance penalty; as all the thread constructs need to cross a<br>
library boundary through an additional function call.<br>
<br>
When the header <__external_threading> is omitted, libc++ is built with the<br>
"libc++ thread API" (declared in <__threading_support>) as the "external" thread<br>
API (basic types are pthread based). An implementation (pthread based) of this<br>
API is provided in test/support/external_threads.<wbr>cpp, which is built into a<br>
separate DSO and linked in when running the libc++ test suite. A test run<br>
therefore demonstrates the second use case (less the intermediate custom API).<br>
