- Subject: [PATCH v2 0/5] Non-contiguous address range bug fixes / improvements
This five part series fixes some bugs associated with GDB's non-contiguous
address range support.
Differences from v1 can be summarized as follows:
- Big block of code in stack.c which handled "certain pathological cases"
was removed entirely. Both Tom and Pedro suggested this change.
- Changes to printcmd.c split out into separate patch; patch expanded
to allow use of data associated with minimal symbol in certain (rare)
cases. (But perhaps not especially rare when dealing with
non-contiguous address ranges.)
- Commit log for negative offset patch expanded with better examples.
- Tests revised slightly to not fail due to change in functionality.
I see no regressions when testing on F30 / x86_64.
Kevin Buettner (5):
Prefer symtab symbol over minsym for function names in non-contiguous
blocks
Restrict use of minsym names when printing addresses in disassembled
code
dwarf2-frame.c: Fix FDE processing bug involving non-contiguous ranges
