GCC11 will warn about a mismatch in the declaration of dwarf_frame_register:
dwarf_frame_register.c:37:61: error: argument 3 of type ‘Dwarf_Op *’
declared as a pointer [-Werror=array-parameter=]
37 | dwarf_frame_register (Dwarf_Frame *fs, int regno, Dwarf_Op *ops_mem,
| ~~~~~~~~~~^~~~~~~
libdw.h:1068:43: note: previously declared as an array ‘Dwarf_Op[3]’
1068 | Dwarf_Op ops_mem[3],
| ~~~~~~~~~^~~~~~~~~~
When fixing that it will show an actual bug in the addrcfi testcase:
addrcfi.c:98:16: error: ‘dwarf_frame_register’ accessing 96 bytes in a
region of size 64 [-Werror=stringop-overflow=]
98 | int result = dwarf_frame_register (stuff->frame, regno, ops_mem, &ops, &nops);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
addrcfi.c:98:16: note: referencing argument 3 of type ‘Dwarf_Op *’
1069 | extern int dwarf_frame_register (Dwarf_Frame *frame, int regno,
| ^~~~~~~~~~~~~~~~~~~~
Fix the declaration, fix the bug and add an extra comment to the description
in libdw.h.

Make sure all structures allocated in the testcases are disposed so
running them under valgrind will show no memory leaks.

- Make the macro names properly scoped (DWARF_ALL_KNOWN_* and
DWARF_ONE_KNOWN_*).
- Simplify the calling convention: don't keep track of the comment
associated with the enumerator, always use the non-_DESC
DWARF_ONE_KNOWN_* callback.
- Install known-dwarf.h alongside libdw.h and others.

We require architecture backends to implement the ebl abi_cfi hook
to provide the ABI's default CFI program as used by the libdw dwarf cfi
functions. There is the addrcfi test program that prints the return
address, cfa location expression and register states as returned by
various dwarf_cfi_* and dwarf_frame functions. But that has to be run
by hand. The new run-addrcfi.sh tests hooks addrcfi up to some existing
architecture specific test files and known addresses to more easily
(and automaticly) check that the default CFI program is implemented
correctly and to test the libdw cfi frame info functionality.
Only i386 and x86_64 are tested for now since other backends don't have
the abi_cfi hook yet.
