At least it seems to do the same thing up to -fdump-tree-optimized. So the problem appears from here to the assembly code!-(I won't comment about the missing controls after ~30 flags;-). Note that the failures disappear with -m64 (missing/bad conversion). > The possible culprits are: 130071 (probably not), 130069, 130067, 130052, > 130050, 130045, > 130043, 130042, 130041, 130040, 130039. I have reverted revisions 130039, 130045, 130067, and 130072, and I have also done a clean bootstrap without changes. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34067
