DWARF loader:
- Multithreading is now contained in the DWARF loader using a jobs queue and a
pool of worker threads.
BTF encoder:
- The parallel reproducible BTF generation done using the new DWARF loader
multithreading model is as fast as the old non-reproducible one and thus is
now always performed, making the "reproducible_build" flag moot.
The memory consumption is now greatly reduced as well.
BTF loader:
- Support for multiple BTF_DECL_TAGs pointing to same tag.
Example:
$ pfunct vmlinux -F btf -f bpf_rdonly_cast
bpf_kfunc bpf_fastcall void *bpf_rdonly_cast(const void *obj__ign, u32 btf_id__k);
$
Regression tests:
- Verify that pfunct prints btf_decl_tags read from BTF.
pfunct:
- Don't print functions twice when using -f.
