lldb.patch1
You can see Entry struct in lldb/include/lldb/Symbol/LineTable.h
file_idx type is NOT uint16_t, provide 11 bits. (... uint16_t file_idx : 11,
...)
our object has many header files more than 2048..
if file_idx is 2691..
file_idx = 2691 (0b101010000011) <-- 12bits
file_idx provides 11 bits.
so, file_idx variable changed from 2691(0b101010000011) to 643(0b01010000011).
I think this is a bug.
Fix it. Please.
you can patch following code(attachment files).
please review and submit it.
I don't know this struct data needs serialization..
