Update btf_parse_elf() to check if .BTF.base section is present.
The logic is as follows:
if .BTF.base section exists:
distilled_base := btf_new(.BTF.base)
if distilled_base:
btf := btf_new(.BTF, .base_btf=distilled_base)
if base_btf:
btf_relocate(btf, base_btf)
else:
btf := btf_new(.BTF)
return btf
In other words:
- if .BTF.base section exists, load BTF from it and use it as a base
for .BTF load;
- if base_btf is specified and .BTF.base section exist, relocate newly
loaded .BTF against base_btf.
