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, and more recent ones such as systemtap. + +Utilities in the dwarves suite include pahole, that can be used to find +alignment holes in structs and classes in languages such as C, C++, but not +limited to these. + +It also extracts other information such as CPU cacheline alignment, helping +pack those structures to achieve more cache hits. + +These tools can also be used to encode and read the BTF type information format +used with the Linux kernel bpf syscall, using 'pahole -J' and 'pahole -F btf'. + +A diff like tool, codiff can be used to compare the effects changes in source +code generate on the resulting binaries. + +Another tool is pfunct, that can be used to find all sorts of information about +functions, inlines, decisions made by the compiler about inlining, etc. + +One example of pfunct usage is in the fullcircle tool, a shell that drivers +pfunct to generate compileable code out of a .o file and then build it using +gcc, with the same compiler flags, and then use codiff to make sure the +original .o file and the new one generated from debug info produces the same +debug info. + +Pahole also 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. + +The btfdiff utility compares the output of pahole from BTF and DWARF to make +sure they produce the same results. + +%package -n %{libname}%{libver} +Summary: Debugging information processing library + +%description -n %{libname}%{libver} +Debugging information processing
