From: "howarth.at.gcc at gmail dot com" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug bootstrap/65733] gcc 4.9.2 suffers bootstrap comparison failures with clang 3.5.1 and later. Date: Sat, 11 Apr 2015 17:12:00 -0000 [thread overview] Message-ID: <bug-65733-4-aHG7aeqsbT@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-65733-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65733 --- Comment #12 from Jack Howarth <howarth.at.gcc at gmail dot com> --- It appears that clang 3.5 and later defaults to setting the CIE version to dwarf2 in the absence of -g. This behavior can't be overridden by passing -gdwarf-3 in the absence of -g. However the gcc configure test failure can be suppressed under clang by appending -gdwarf-2 instead (to downgrade the CIE version to dwarf3 in the presence of -g).
