--- Comment #27 from Dan Horák <dan at danny.cz> ---
and the results are

s390
- the -O1 override is ineffective, the build system sets -O2 later on the
command line
g++ -c -pipe -O1 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fstack-protector
--param=ssp-buffer-size=4 -m31 -march=z9-109 -mtune=z10 -O2 -std=c++0x
-fvisibility=hidden -fvisibility-inlines-hidden -Wall -W -D_REENTRANT
-fno-exceptions -fPIC -DQT_NO_LIBUDEV -DQT_NO_USING_NAMESPACE
-DQT_BUILD_GUI_LIB -DQT_BUILDING_QT -DQT_NO_CAST_TO_ASCII
-DQT_ASCII_CAST_WARNINGS -DQT_MOC_COMPAT -DQT_USE_QSTRINGBUILDER

- -O3 is used from the #pragma anyway
- builds fine with the #pragma commented out

s390x
- fails with 3 GB of memory (1G ram + 2G swap), but succeeds with 8 GB (3 + 5)

ppc/ppc64
- fails with error in dialogs/qprintdialog_unix.cpp:54
- http://ppc.koji.fedoraproject.org/koji/taskinfo?taskID=886976

arm
- http://arm.koji.fedoraproject.org/koji/taskinfo?taskID=1409787 - no results
yet


I think the huge memory requirements with -O3 on s390/s390x prove Jakub's
statement that -O3 can't be enabled globally as it is not safe and the quality
varies between arches
