Subject: [PATCH v2 31/31] perf build: Remove PERF_HAVE_DWARF_REGS
Date: Sat, 5 Oct 2024 12:55:41 -0700 [thread overview]
Message-ID: <20241005195541.380070-32-irogers@google.com> (raw)
In-Reply-To: <20241005195541.380070-1-irogers@google.com>
PERF_HAVE_DWARF_REGS was true when an architecture had a dwarf-regs.c
file. There are no more architecture dwarf-regs.c files, selection is
done using constants from the ELF file rather than conditional
compilation. When removing PERF_HAVE_DWARF_REGS was the only variable
in the Makefile, remove the Makefile.
Add missing SPDX for RISC-V Makefile.
Signed-off-by: Ian Rogers <irogers@google.com>
