Description Thomas Koenig 2018-03-31 12:21:42 UTC 
There is a major problem in setting breakpoints in gcc functions
when -freorder-blocks-and-partition is in effect (which is
the default in recent gcc): Stepping with "s" is broken when
stepping into a function.

A test case plus some discussion can be found at
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=84550 .

I'm setting milestone so we don't forget evaluating before 8.1.1 is out.

Changing the milestone as discussed on gdb-patches:

AFAICT, this is now solved, so closing. Please re-open if mistaken. Thanks!
