At least, I hope not! However, if you did an incremental build, previously libllvm and friends were built from .o files (i.e. position dependent). These were then added to a static library, with a .a extension. Now libllvm and friends are built as shared libraries, therefore all the objects have to rebuilt as position independent (PIC), with a .pico extension. Similarly, a number of tools built under usr.bin/clang have been switched to position independent (PIE), therefore their objects also have to be rebuilt: instead of .o, these now use .pieo. In any case, ccache will still help if you do future rebuilds. It is only with this particular transition that a number of objects really have to be fully recompiled. -Dimitryhelp
