(<a href="http://gcc.gnu.org/gcc-4.7/changes.html" target="_blank">http://gcc.gnu.org/gcc-4.7/changes.html</a>). The main change is that now<br>
mingw (like msvc) given thiscall calling convention to methods by<br>
default.<br>
<br>
I think the last bug blocking us to support the new abi has just been<br>
fixed. The question now is how to switch.<br>
<br>
The attached patches simply switch llvm and clang to the new ABI. This<br>
is similar to what gcc did on 4.7. The timing is also good as we will<br>
not build with 4.6 anymore when we switch to c++11.<br>
<br>
Is anyone depending on targeting the 4.6 mingw ABI even after we drop<br>
support for building with 4.6?<br>
<br>
