Here is a patch from our backlog that addresses a libitm issue where
setting ENABLE_LTO=1 in site.exp causes the following error with dejagnu:
ERROR: (DejaGnu) proc "libitm_target_compile linker_plugin19344.c
linker_plugin19344.exe executable {{additional_flags=-flto
-fuse-linker-plugin}}" does not exist.
This problem usually does not occur since the default site.exp does not
contain ENABLE_LTO=1. This patch has been tested both with and without
our custom site.exp.
Is this OK for trunk? If so, please check it in since I do not have commit
rights.
