From: "zackw at panix dot com" <sourceware-bugzilla@sourceware.org> To: glibc-bugs@sourceware.org Subject: [Bug libc/17307] Spurious -Wsign-conversion warning with clang-3.5, due to excessively clever glibc <sys/resource.h> Date: Mon, 25 Aug 2014 18:54:00 -0000 [thread overview] Message-ID: <bug-17307-131-wxL8bTAhrS@http.sourceware.org/bugzilla/> (raw) In-Reply-To: <bug-17307-131@http.sourceware.org/bugzilla/> https://sourceware.org/bugzilla/show_bug.cgi?id=17307 --- Comment #2 from Zack Weinberg <zackw at panix dot com> --- gcc-4.9's -Wsign-conversion does not complain. I think this may actually be a lacuna in gcc's implementation of those warnings, because *this* program... #include <sys/resource.h> #include <stdio.h> #include <type_traits> int main(void) { printf("%d %d\n", std::is_signed<enum __rlimit_resource>::value, std::is_signed< std::underlying_type< enum __rlimit_resource>::type>::value); return 0; } ... prints "0 0" when compiled with either clang++3.5 or g++4.9. -- You are receiving this mail because: You are on the CC list for the bug.
