Hi Martin,
I noticed one can't build 5.19 with latest binutils master. One see the following error: [ 1413s] BTF .btf.vmlinux.bin.o [ 1413s] Unsupported DW_TAG_unspecified_type(0x3b)
<0><c>: Abbrev Number: 3 (DW_TAG_unspecified_type) <--- the problematic TAG
Is it something pahole should handle?
Yes, I believe so. The tag is a valid DWARF tag, and GDB wants it, so it would be good if pahole could support it. Cheers Nick
