Bug ID: 66172
Summary: -fno-threadsafe-statics suppresses guard functions but
not guard variables
Product: gcc
Version: 4.9.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: eleventen at gmail dot com
Target Milestone: ---
The use of the -fno-threadsafe-statics eliminates the function references to
the guard functions,
__cxa_guard_acquire
__cxa_guard_release
but it doesn't eliminate the variables used to guard the initialization. A
compiled version of the attached file using the g++ command line therein
generated no references to the guard functions, but the guard variable remains.
# nm -C guard | grep guard
0000000000600a88 b guard variable for f()::a
--- Comment #1 from Marc Singer <eleventen at gmail dot com> ---
I neglected to include the version information:
# g++ --version
g++ (Debian 4.9.2-10) 4.9.2
