From ddbfb6f20c1b7a8b111e2194fff767cea032d491 Mon Sep 17 00:00:00 2001 From: Ian Rogers Date: Fri, 8 Nov 2024 15:46:05 -0800 Subject: perf build: Remove PERF_HAVE_DWARF_REGS 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.
