- Subject: Debugging LTO.
- Authentication-results: sourceware.org; auth=none
Are there any tricks I can use to debug an LTO ICE? Lto1 --help does not seem to
give me an option to output trace dumps etc.
What I suspect is happening is that cc1 builds erroneous LTO IR info in the
objects that causes the ICEs. Is there a reader that will dump the IR from these
LTO objects? AFAICS, this page
says such a reader is still a TODO.
