Description Brian Lane 2017-02-17 20:26:11 UTC
The mass rebuild with the new version of gcc is causing gnupg builds to fail on the armv7hl arch, it works fine on all the other arches.

If I change the optimization from -O2 to -O1 the tests pass.

Failing build:
https://koji.fedoraproject.org/koji/taskinfo?taskID=17920462

Successful build:

This bug appears to have been reported against 'rawhide' during the Fedora 26 development cycle.
Changing version to '26'.

mpih-div.i.bz2

Bisection seems to reveal that it is mpi/mpih-div.c that matters, at least if all the object files are compiled with -O2 and this single one with -O1, tests pass, if all objects are compiled with -O1 and this single one with -O2, the test fail the same.

Command line:
gcc -O2 -g -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -march=armv7-a -mfpu=vfpv3-d16  -mfloat-abi=hard -fPIE -S -o mpih-div.s mpih-div.i

Comment 3 Jakub Jelinek 2017-05-16 21:13:40 UTC
Bisected to http://gcc.gnu.org/r241660 change.

Comment 4 Jakub Jelinek 2017-05-22 08:14:28 UTC
So the bug is actually in gnupg that it uses helplessly obsolete longlong.h.
This has been fixed in https://gcc.gnu.org/ml/gcc-patches/2005-10/msg00546.html
and committed as r106491.  Current gmp longlong.h seems to be fine too.
