Eduard Zingerman 5506b7d7bb selftests/bpf: make BPF_TARGET_ENDIAN non-recursive to speed up *.bpf.o build ... BPF_TARGET_ENDIAN is used in CLANG_BPF_BUILD_RULE and co macros. It is defined as a recursively expanded variable, meaning that it is recomputed each time the value is needed. Thus, it is recomputed for each *.bpf.o file compilation. The variable is computed by running a C compiler in a shell. This significantly hinders parallel build performance for *.bpf.o files. This commit changes BPF_TARGET_ENDIAN to be a simply expanded variable. # Build performance stats before this commit $ git clean -xfd; time make -j12 real 1m0.000s ... # Build performance stats after this commit $ git clean -xfd; time make -j12 real 0m43.605s ...
