Bug ID: 115433
Summary: unexpected increase of testsuite execution time
Product: gcc
Version: 14.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: jbeulich at suse dot com
Target Milestone: ---
With the usual, moderate increase of the number of tests it is somewhat
unexpected that a testsuite run now takes 50% more time for x86-64 targets, and
about 100% more for i686 targets (and there already with a 64-bit kernel
underneath). For comparison, taking a representative 64-bit system, testsuite
runs took
- gcc: a little over an hour
- g++: less than 40 min
- libstdc++: 3 hours
IOW what already took longest before has now further increased by a significant
percentage. (Absolute numbers are bigger on two or three generations older
hardware, but the relative values remain largely the same.)
All of this said - I certainly understand that moderate increases of overall
execution time is always to be expected for a new major release. It's just that
this time it's not quite "moderate" anymore.
