In most cases when the bug is reproduceable and a single preprocessed
source is enough (e.g. not LTO build etc.), the gcc driver dumps all the
required info into /tmp/.
That is the -freport-bug
Preprocessed source stored into /tmp/ccXXXXXX.out file, please attach this to your
bugreport.
message.
So, if mock + koji copied those over (best xz or bzip2 compressed) alongside with
build.log / root.log etc. in case the build failed, that would be very much
appreciated.
We were actually speaking with the mock guys about this in Brno last
week. From a koji PoV it just stores the files that mock spits out
which at the moment is just the build logs plus any *rpm files so it
shouldn't be too hard to extend mock to enable the output of extra
debug files.
