Looks like I should have RTFM properly.
It's clearly stated that -flto is not compatible with -g at this time.
Sorry if I wasted anyone's time,
Patrick
Hi,
I'm running into an internal compiler error when trying to build a
powerpc project.
In the past when I've run into ICEs I usually submit the preprocessed
source as part of the bug report. In this case I'm not sure what to
submit as the error is occuring during the LTO link phase.
Running gcc with -v -save-temps results in the following output and a
bunch of *.ltrans??.o files a ltrans.out file and a libgcc.res file.
Are these of any use or do the original object files need to be
included in the bug report?
Also, is there any other way to diagnose what's going wrong here?
Thanks,
Patrick
