This allows to pass particular flags and parameters to the feature checks compilation. Use the per-feature check flags for the unwinding feature in order to correctly compile the libunwind and libunwind-debug-frame feature checks. This change set simplifies the flags passing mechanism between the Makefiles in config/Makefile and config/feature-checks; this could be farther optimized by moving the compilation flags to the per-feature check flags for all features to be checked. Tested on x86_64, ARMv7 and ARMv8 with and without LIBUNWIND_DIR set in 'make -C tools/perf' Jean Pihet (2): perf: add per-feature check flags perf: unwinding: use the per-feature check flags tools/perf/config/Makefile | 48 +++++++++++++++++-------------- tools/perf/config/feature-checks/Makefile | 8 +++--- 2 files changed, 30 insertions(+), 26 deletions(-) -- 1.7.11.7
