Hi,
There are ~100 failures on each *-rtems* target
in the latest test runs when various lto related
flags are on. The symbols in questions are in the
RTEMS libraries which are picked up via the
-B... argument. Other symbols from the same
library are resolved.
These have all cropped up since -fuse-linker-plugin became the default.
Ahh. And I am using the heads of binutils, gcc, newlib, gdb, and rtems
so it is getting enabled.
Should LTO work with a target not using gold?
Yes, it should, but some work is needed at the binutils end. I am testing
the attached two patches at the moment; the idea is to have fully-debugged
support for LTO+plugin in the 2.20.1 release, to support 4.6.0 when it comes
out.
There are still some rtems targets which need to finish from the
last full build. But I will try your patches once that is done.
If it is still broken, what do you need gathered up to have a test case?
Thanks.
cheers,
