Description Franz Trischberger 2013-08-15 06:48:47 UTC

emerge valgrind && emerge -1 libdrm
[snip]
checking for native atomic primitives... Intel
checking for PCIACCESS... yes
checking for VALGRIND... yes
checking that generated files are newer than configure... done
configure: creating ./config.status
[snap]

I do not exactly know what this does. (I think it will enable suppressions for certain calls to not trigger false positives, e.g. "hidden" frees etc.) But I think there should be a USE-Flag to toggle the DEP.
A quick grep in my build logs showed quite some hits:
vim-core, notmuch, udev, mpd, gst-plugins-ffmpeg, systemd, xapian, ruby. Also gcc checks for valgrind, but I do not have a gcc-build.log from after I first installed valgrind, so those checks return "no".

Probably a TRACKER bug would be great to find all those automagics. And add a global valgrind USE-Flag.

This is right.

Does anyone know how the emitted suppressions work?

should be all set now in the tree; thanks for the report!
