perf build: Rename HAVE_DWARF_SUPPORT to HAVE_LIBDW_SUPPORT

2024-10-18T17:17:40+00:00

In Makefile.config for unwinding the name dwarf implies either libunwind or libdw. Make it clearer that HAVE_DWARF_SUPPORT is really just defined when libdw is present by renaming to HAVE_LIBDW_SUPPORT.

perf debuginfo: Fix the build with !HAVE_DWARF_SUPPORT

2024-08-09T20:37:03+00:00

In that case we have a set of placeholder functions, one of them uses a 'Dwarf_Addr' type that is not present as it is defined in the missing DWARF libraries, so provide a placeholder typedef for that as well. The build error before this patch: In file included from util/annotate.c:28: util/debuginfo.h:44:46: error: unknown type name ‘Dwarf_Addr’ 44 | Dwarf_Addr *offs __maybe_unused, | ^~~~~~~~~~ make[6]: *** [/home/acme/git/perf-tools-next/tools/build/Makefile.build:106: util/annotate.o] Error 1 make[6]: *** Waiting for unfinished jobs....

Split debuginfo data structure and related functions into a separate file so that it can be used by other components than the probe-finder.
