I also added an abort() when _dwarf_get_reloc_size() returns on
"/* unknown relocation. */" and this killed nbctfconvert() as
_dwarf_get_reloc_size ()
_dwarf_elf_init ()
dwarf_elf_init ()
dw_read ()
main ()
For me nbctfmerge on kernels succeeds after up to 30 minutes, but the
resulting CTF sections are long too big and look very strange:
Before this change I had
total number of types = 30015
total number of integers = 65
total number of floats = 1
total number of pointers = 7902
total number of arrays = 3515
total number of func types = 2252
and now i have
total number of types = 322862
total number of integers = 3865
total number of floats = 1
total number of pointers = 127495
total number of arrays = 14350
total number of func types = 65411
and running the merge with CTFMERGE_DEBUG_LEVEL=2 I get
ERROR: nbctfmerge: Second pass for 5978 ((anon)) == 13434
