With respect only to '__attribute__((internal_linkage))', not 'nodebug' and other parts of this topic; does hiding "some" members and not others not introduce a violation of the ODR because some members of the class as it appears in one translation unit are not the same actual definitions as the apparently "same" membe...

Hi Evgenii, I was wondering what the status is of your work to attach "internal_linkage" to methods of standard library classes in libc++. The following piece of code doesn't link because a symbol (string::empty) is undefined and it sounds like your work might fix the linkage error I'm seeing. $ cat test1.cpp #include <string> #include <functional> int main...

The proposed attribute is a rough equivalent of static void foo::do_method(void) { // implementation here } where "static" does not mean a static class member, but makes the declaration local to the translation unit. C-style "static". The patch in http://r...

...match instruction patterns to their own ISA's bitreverse instruction. See also the patch to the ARM backend that replaces ARMISD::RBIT with ISD::BITREVERSE. [r252878](http://reviews.llvm.org/rL252878), [r253047](http://reviews.llvm.org/rL253047). ## Clang commits * Support for `__attribute__(internal_linkage)` was added. This is much like C's static keyword, but applies to C++ class methods. [r252648](http://reviews.llvm.org/rL252648). * Clang now supports GCC's `__auto_type` extension, with a few minor enhancements. [r252690](http://reviews.llvm.org/rL252690). ## Other project commits * l...
