Subject: [PATCH 2/7] btf_encoder: Add extra debug info for unsupported DWARF
|
|
tags
|
|
|
|
Recently we got a report of DW_TAG_unspecified_type triggering this
|
|
warning:
|
|
|
|
[ 1413s] BTF .btf.vmlinux.bin.o
|
|
[ 1413s] Unsupported DW_TAG_unspecified_type(0x3b)
|
|
[ 1413s] Encountered error while encoding BTF.
|
|
|
|
Probably tag->type is zero, but would be great to have this offhand, add
|
|
that info to the error message.
