nativeGen/dwarf: Fix procedure end addresses
Previously the .debug_aranges
and .debug_info
(DIE) DWARF
information would claim that procedures (represented with a
DW_TAG_subprogram
DIE) would only span the range covered by their entry
block. This omitted all of the continuation blocks (represented by
DW_TAG_lexical_block
DIEs), confusing perf
. Fix this by introducing
a end-of-procedure label and using this as the DW_AT_high_pc
of
procedure DW_TAG_subprogram
DIEs
Fixes #17605 (closed).
Additionally fix two smaller issues:
- Generate
DW_TAG_source_note
nodes only with-g3
- Use the
DW_AT_linkage_name
attribute instead ofDW_AT_MIPS_linkage_name
(it's unclear why this was used originally)
