External .debuginfo files

[spaace]

Hi,

Can someone please explain how external .debuginfo files are used?

When jdk build is run, i can see that it generates .debug files in the
.debuginfo package.

However if i provide the flag "--with-native-debug-symbols=external", a set
of .debuginfo files are also created.

I know that GDB and similar tools know how to use the .debug files but iam
not sure who/what can use the .debuginfo files.

In general what are the recommended settings for creating release binaries,
along with EXTERNAL files that do not affect the run time, but can be used
to debug the libraries IF REQUIRED?

Thanks
Arun
