------- Comment #173 from rguenth at gcc dot gnu dot org 2007-06-09 09:48 -------
Full testing shows no (or at least < 0.5%) performance regression on tramp3d
runtime. Compile time seems to go up by 0.5% (that looks consistent, about the
same with previous patches) for tramp3d. Testcases not using placement new
don't seem to be affected.
The patch still fixes the FreePOOMA problems that caused me to file this PR.
So, from my point of view the patch is ready to be exposed to more eyes.
Thanks,
Richard.
