dwarves is a set of tools that use the debugging information inserted in
|
|
|
7ee4d9 |
ELF binaries by compilers such as GCC, used by well known debuggers such as
|
|
|
7ee4d9 |
GDB, and more recent ones such as systemtap.
|
|
|
7ee4d9 |
|
|
|
7ee4d9 |
Utilities in the dwarves suite include pahole, that can be used to find
|
|
|
7ee4d9 |
alignment holes in structs and classes in languages such as C, C++, but not
|
|
|
7ee4d9 |
limited to these.
|
|
|
7ee4d9 |
|
|
|
7ee4d9 |
It also extracts other information such as CPU cacheline alignment, helping
|
|
|
7ee4d9 |
pack those structures to achieve more cache hits.
|
|
|
7ee4d9 |
|
|
|
7ee4d9 |
These tools can also be used to encode and read the BTF type information format
|
|
|
7ee4d9 |
used with the Linux kernel bpf syscall, using 'pahole -J' and 'pahole -F btf'.
|
|
|
7ee4d9 |
|
|
|
7ee4d9 |
A diff like tool, codiff can be used to compare the effects changes in source
|
|
|
7ee4d9 |
code generate on the resulting binaries.
|
|
|
7ee4d9 |
|
|
|
7ee4d9 |
Another tool is pfunct, that can be used to find all sorts of information about
|
|
|
7ee4d9 |
functions, inlines, decisions made by the compiler about inlining, etc.
|
|
|
7ee4d9 |
|
|
|

One example of pfunct usage is in the fullcircle tool, a shell that drivers
|
|
|
33b5c8 |
pfunct to generate compileable code out of a .o file and then build it using
|
|
|
33b5c8 |
gcc, with the same compiler flags, and then use codiff to make sure the
|
|
|
33b5c8 |
original .o file and the new one generated from debug info produces the same
|
|
|
33b5c8 |
debug info.
|
|
|
33b5c8 |
|
|
|
33b5c8 |
Pahole also can be used to use all this type information to pretty print raw data
|
|
|
33b5c8 |
according to command line directions.
|
|
|
33b5c8 |
|
|
|
33b5c8 |
Headers can have its data format described from debugging info and offsets from
|
|
|
33b5c8 |
it can be used to further format a number of records.
|
|
|
33b5c8 |
|
|
|
33b5c8 |
The btfdiff utility compares the output of pahole from BTF and DWARF to make
|
|
|
33b5c8 |
sure they produce the same results.
