Bug #: 50345 Summary: Incomplete GCC Internals sentence on LTO Classification: Unclassified Product: gcc Version: unknown Status: UNCONFIRMED Severity: normal Priority: P3 Component: other AssignedTo: unassig...@gcc.gnu.org ReportedBy: paulo.ma...@csr.com In the GCC Internals manual, LTO chapter (http://gcc.gnu.org/onlinedocs/gccint/LTO.html) there's the sentence (2nd paragraph): "A, perhaps surprising, side effect of this feature is that any mistake in the toolchain that leads to LTO information not being used (e.g. an older libtool calling ld directly)." I have a feeling that the mentioned 'surprising side effect' is never actually explained.
