From: "pinskia at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug c++/85461] A simple recursive TMP static const initializer defeats gcc Date: Wed, 22 Dec 2021 01:45:40 +0000 [thread overview] Message-ID: <bug-85461-4-vSRrClpeA3@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-85461-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85461 --- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> --- Using constexpr is a decent workaround. Note enum version of this is rejected by all compilers: template<unsigned int v> struct bitWidthHolding { enum {width = (v == 0) ? 0 : bitWidthHolding<(v>>1)>::width + 1}; }; int a = bitWidthHolding<255>::width; Which I find interesting.
