--- Comment #28 from Martin Jambor <jamborm at gcc dot gnu.org> --- (In reply to Martin Jambor from comment #27) > Unfortunately, something else has added a further gigabyte to WPA of > FF in the last week: So this fortunately turnout to be a mistake in measurement, I was comparing a --enable-gather-detailed-mem-stats build with a normal one. The correct values are: | compiler | wpa mem (KB) | wpa mem (GB) | |---------------------+--------------+--------------| | gcc 6 branch | 4046451 | 3.86 | | trunk rev. 245382 | 5468227 | 5.21 | | patched rev. 245382 | 4255799 | 4.06 | | trunk rev. 245595 | 5452515 | 5.20 | | patched rev. 245595 | 4240379 | 4.04 | Thus, the patch avoids most of the reported increase in memory use.
