This release includes improvements to
--map-path options for the processing
of core dump files, significant performance improvements, support for GNU
DWARF compression extensions and improved unwinding and variable resolution
accuracy. All users are recommended to upgrade.
Map Path Handling
Previously, linker entries extracted from core dump files did not respect
--map-path option (
sysroot-equivalent for GDB). This is now respected.
Line number resolution performance for certain workloads is improved by 30% to 70% through micro-optimizations to the sorting algorithm.
Unwinding and Variable Resolution Accuracy
FORM_addr fields were respected for
FORM_udata is also respected now. It was
possible for debug information associated with a compilation unit to be
FORM_udata was used.
Support has been added for various GNU extensions (namely,
FORM_GNU_strp_alt) used by the
dwz DWARF compression tool. These
are required by customers utilizing DWARF compression with
