Bug ID: 23021
Summary: Setting breakpoints with
-freorder-blocks-and-partition
Product: gdb
Version: 8.0.1
Status: NEW
Severity: normal
Priority: P2
Component: gdb
Assignee: unassigned at sourceware dot org
Reporter: tkoenig at gcc dot gnu.org
Target Milestone: ---

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.
