From: Jonathan Wakely <redi@gcc.gnu.org> To: gcc-cvs@gcc.gnu.org, libstdc++-cvs@gcc.gnu.org Subject: [gcc r11-4518] libstdc++: Rename _UniformRandomNumberGenerator parameters Date: Thu, 29 Oct 2020 09:09:59 +0000 (GMT) [thread overview] Message-ID: <20201029090959.41542385700E@sourceware.org> (raw) https://gcc.gnu.org/g:68990ed13dc36cb98f94afa84e9dadc39e955e8c commit r11-4518-g68990ed13dc36cb98f94afa84e9dadc39e955e8c Author: Jonathan Wakely <jwakely@redhat.com> Date: Thu Oct 29 09:09:44 2020 +0000 libstdc++: Rename _UniformRandomNumberGenerator parameters The paper P0346R1 renamed uniform random number generators to uniform random bit generators, to describe their purpose more accurately. This makes that same change in one of the relevant files (but not the others). libstdc++-v3/ChangeLog: * include/bits/uniform_int_dist.h (uniform_int_distribution): Rename _UniformRandomNumberGenerator template parameters to _UniformRandomBitGenerator, as per P0346R1.
