dwarves

Debugging information processing library and utilities

Dwarves is a set of tools that use the debugging information inserted in ELF binaries by compilers such as GCC, used by well known debuggers such as GDB.

Utilities in the Dwarves suite include pahole, that can be used to find alignment holes in structures and classes in languages such as C, C++, but not limited to these. These tools can also be used to encode and read the BTF type information format used with the kernel Linux bpf syscall.

The codiff command can be used to compare the effects changes in source code generate on the resulting binaries.

The pfunct command can be used to find all sorts of information about functions, inlines, decisions made by the compiler about inlining, etc.

The pahole command can be used to use all this type information to pretty print raw data according to command line directions.

Headers can have its data format described from debugging info and offsets from it can be used to further format a number of records.

Finally, the btfdiff command can be used to compare the output of pahole from BTF and DWARF, to make sure they produce the same results.
