[PATCH] D73282: Fix debug-info generation for block invocations so that we set the LinkageName instead of the Name

[Shafik Yaghmour via Phabricator via cfe-commits]

shafik added a comment.

Example as requested, using the same code from `clang/test/CodeGenCXX/debug-info-block-invocation-linkage-name.cpp` the DWARF for block created in `f()` and passed to `g()` as an argument changes from:

  0x00000052:   DW_TAG_subprogram
                  DW_AT_low_pc	(0x0000000000000060)
                  DW_AT_high_pc	(0x0000000000000089)
                  DW_AT_frame_base	(DW_OP_reg6 RBP)
                  DW_AT_name	("___Z1fU13block_pointerFviE_block_invoke")
                  DW_AT_decl_file	("block_demangle_3.cpp")
                  DW_AT_decl_line	(4)

to

  0x00000056:   DW_TAG_subprogram
                  DW_AT_low_pc	(0x0000000000000060)
                  DW_AT_high_pc	(0x000000000000008c)
                  DW_AT_frame_base	(DW_OP_reg6 RBP)
                  DW_AT_linkage_name	("___Z1fU13block_pointerFviE_block_invoke")
                  DW_AT_decl_file	("block_demangle_3.cpp")
                  DW_AT_decl_line	(4)

With the only change being that the mangled name `___Z1fU13block_pointerFviE_block_invoke` instead of ended up in `DW_AT_name` end up in `DW_AT_linkage_name`
