From 5ead949920c773d4c3a42988391c2e6d0f32650f Mon Sep 17 00:00:00 2001 From: Mykyta Yatsenko Date: Thu, 22 May 2025 02:38:13 +0100 Subject: [PATCH] selftests/bpf: Add SKIP_LLVM makefile variable Introduce SKIP_LLVM makefile variable that allows to avoid using llvm dependencies when building BPF selftests. This is different from existing feature-llvm, as the latter is a result of automatic detection and should not be set by user explicitly. Avoiding llvm dependencies could be useful for environments that do not have them, given that as of now llvm dependencies are required only by jit_disasm_helpers.c.
