Haojian Wu <hokein.wu at gmail dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |hokein.wu at gmail dot com --- Comment #15 from Haojian Wu <hokein.wu at gmail dot com> --- Hi, I notice that the __is_deducible was hidden in the commit https://github.com/gcc-mirror/gcc/commit/30556bf81f4385c2a9c449948865dbcf35664764. Is there any reason behind the change? (Context: I'm implementing the is_deducible part for alias CTAD in clang, and I'm considering to add a similar builtin in clang).
