Doc Text:
Important: if this rebase instead contains *only bug fixes,* or *only enhancements*, select the correct option from the Doc Type drop-down list. Rebase package(s) to version: 0.157 Highlights, important fixes, or notable enhancements: For this bug in particular: Cause: dwarf_getfuncs should return all functions defined by a given compilation unit. But when considering candidate nodes, it only scanned the first layer of nodes attached to a given compilation unit, even though such function definition nodes could be nested in deeper layers of the Dwarf tree. GCC emits Dwarf nodes representing nested functions under the nodes that represent the outer function. Consequence: dwarf_getfuncs wouldn't report nested functions for GCC-generated Dwarf data. Fix: The whole Dwarf tree rooted at a given compilation unit is scanned. Result: All function definitions are found.
