Hi,
DWZ 0.13 has been released.
There is a web page for DWZ at:
https://sourceware.org/dwz/
DWZ 0.13 includes the following changes and enhancements:
* DW_OP_GNU_variable_value support.
* A multifile with only a .debug_str section is now allowed. Previously
this resulted in an error "dwz: <multifile>: .debug_info section not
present".
* Improved handling of unordered section header table. Previously this
resulted in an error "dwz: Section offsets in <file> not monotonically
increasing".
* Improved handling of NOBITS sections generated by objcopy
--only-keep-debug. Previously this resulted in an error "dwz:
Allocatable section in <file> after non-allocatable ones".
* Sections .debug_gnu_names and .debug_gnu_types are now handled, by
removing them from the output file (similar to what is done for
sections .debug_names and .debug_types). Previously this resulted in
an error "dwz: Unknown debugging section <section>".
* A case where previously the error "dwz: Error mmapping multi-file
temporary files" was generated, now is handled by generating the error
"dwz: No suitable DWARF found for multifile optimization".
* A case where previously the error "dwz: DWARF version 0 unhandled"
was generated, is now handled by generating the error "dwz: Found
compressed .debug_info section, not attempting dwz compression".
* Fixed multifile mode exit status to behave the same as non-multifile
mode exit status.
* When running into "dwz:<file>: .debug_info section not present" , dwz
now exits with 0.
* The following assertion failures were fixed:
- dwz.c:2363: checksum_die: Assertion `
((!op_multifile && !rd_multifile && !fi_multifile)
|| cu != die_cu (ref))
&& (!op_multifile || cu->cu_chunk == die_cu (ref)->cu_chunk)
' failed.
- dwz: dwz.c:8558: adjust_exprloc: Assertion `
refd != NULL && !refd->die_remove
' failed.
- dwz: dwz.c:1722: read_loclist: Assertion `
ptr + len <= endsec
' failed.
- dwz: dwz.c:9068: write_die: Assertion `
p && (form == DW_FORM_sec_offset || form == DW_FORM_data4)
' failed
- dwz: dwz.c:9901: read_dwarf: Assertion `
data != NULL && data->d_buf != NULL
' failed
* A testsuite was added.
Thanks,
- Tom
