libdw: Add new DWARF5 Dwarf expression operations.

2018-03-11T15:34:02+00:00

DW_OP_implicit_pointer, DW_OP_entry_value, DW_OP_const_type,
DW_OP_regval_type, DW_OP_deref_type, DW_OP_xderef_type,
DW_OP_convert and OP_reinterpret are implemented like their
pre-DWARF5 GNU variants.

DW_OP_xderef_type is implemented as a (non-CU relative) variant of
DW_OP_deref_type.

DW_OP_addrx and DW_OP_constx are recognized but not interpreted yet.

libdw: Parse new DWARF5 units and CU DIEs.

2018-02-21T16:04:32+00:00

Parse DWARF5 units, add the unit_type to the Dwarf_CU and generalize some
code calculating the header length and getting at the first DIE of a unit.
Unit headers can have different sizes depending on the unit type.

Remove old-style function definitions.

2015-09-23T13:50:55+00:00

We already require -std=gnu99 and old-style function definitions might
hide some compiler warnings.

libdw: Make sure all attributes come with a (fake) CU for bound checks.

2014-12-17T15:35:56+00:00

All attributes now have a reference to a (fake) CU that has startp and
endp set to the data section where the form data comes from. Use that
for bounds checking in __libdw_form_val_len and dwarf_formblock to make
sure data read doesn't overflow any data section. Remove libdwP.h cu_data
and use cu startp and endp directly where appropriate.

libdw: Handle empty location expression for (indirect) DIE locations.

2013-12-13T13:23:02+00:00

When dwarf_getlocation_implicit_pointer and dwarf_getlocation_attr
refer to a DIE that doesn't contain a DW_AT_location then don't generate
an error, but return an empty location expression to signal the actual
value pointed to is not available. This isn't invalid DWARF. Also make
sure that __libdw_intern_expression handles empty location expressions.

Update name, license and contributor policy.

2012-06-05T21:12:05+00:00

* Change name from "Red Hat elfutils" to "elfutils".
* Update license of standalone tools and test from GPLv2 to GPLv3+.
* Change license of libraries from GPLv2+exception to GPLv2/LGPLv3+.
* Add Developer Certificate of Origin based contributor policy.

top-level:

- COPYING: Upgraded from GPLv2 to GPLv3.
- CONTRIBUTING, COPYING-GPLv2, COPYING-LGPLv3: New files.
- NEWS: Added note about new contribution and license policy.
- Makefile.am: Updated to GPLv3, added new files to EXTRA_DIST.
- configure.ac: Update to GPLv3, changed AC_INIT name to 'elfutils'.

backends, lib, libasm, libcpu, libdw, libdwfl, libebl, libelf:

- All files updated to GPLv2/LGPLv3+. Except some very small files
  (<5 lines) which didn't have any headers at all before, the linker
  .maps files and the libcpu/defs files which only contain data and
  libelf/elf.h which comes from glibc and is under LGPLv2+.

config:

- elfutils.spec.in: Add new License: headers and new %doc files.
- Update all license headers to GPLv2/LGPLv3+ for files used by libs.

src, tests:

- All files updated to GPLv3+. Except for the test bz2 data files, the
  linker maps and script files and some very small files (<5 lines)
  that don't have any headers.
