Hi, Please point me to documentation where relation between specifying: flto=x and flto-partition=y described completely over the domain of possible (x, y) pairs. I experience troubles with deducing possible values and their effect from source code of gcc, google isn't helpful too. Now I am trying to solve one particular problem with inlining (lto compilation) in private backend (core compiler is gcc 4.6.3). In brief: there is some code A, containing functions a() and b(). Being compiled with lto, b() is inlined in a() as it supposed to be. Now consider larger code B. B have no references to both a() and b(), but if we compile A+B with lto, b() is no more inlined into a(). I suppose problem is in LTO partition -- in situation of more code, partitioned part may contain some other functions b() refers to, so b() now can not be inlined in the presence of inter-module references. But I am not sure what options I can specify to control partition and tune lto compilation to catch problem between options, not between sources. --- With best regards, Konstantin
