Bug 10738 - Cannot set breakpoint on inlined function

Bug 10738 - Cannot set breakpoint on inlined function

[Andrew Cagney]

This bug apparently recently came up on the GCC lists, and RMS is
drawing it to our attention.  Does it pique anyone's interest?

while it is sure a high priority Bug it is meaningful only for interactive
debugging of -O2 -g code.  AFAIK most of the GDB use cases is only for
backtracing, both automatic (ABRT, Apport, others) and by hand (bt+quit) as
people do not want to learn all the GDB commands.

-O2 -g interactive debugging (stepping) is not yet much feasible due to the
"jumping around" as GCC does not produce valid DW_LNS_negate_stmt and does not
properly undo/redo variable states by DWARF across scheduled instructions, as
planned by Alexandre Oliva.

The highest priority is to get at least the backtraces working for -O2 -g code.
For example archer-jankratochvil-entryval for it I will submit these weeks.


Thanks,
Jan
