When building debug use -Og as the optimization level if its available, otherwise retain the use of -O0. -Og has been added by GCC to enable all optimizations that to not affect debugging while retaining full debugability.
Signed-off-by: Doug Goldstein <car...@cardoe.com> --- change since v2: - switch back to cc-option-add to not call cc-option on every invocation change since v1: - switch to cc-option to only specify -O0 if -Og isn't supported --- tools/Rules.mk | 1 + 1 file changed, 1 insertion(+) diff --git a/tools/Rules.mk b/tools/Rules.mk index 9ef0b47..1b79a6e 100644 --- a/tools/Rules.mk +++ b/tools/Rules.mk @@ -138,6 +138,7 @@ SHLIB_libxenvchan = $(SHDEPS_libxenvchan) -Wl,-rpath-link=$(XEN_LIBVCHAN) ifeq ($(debug),y) # Disable optimizations and enable debugging information for macros CFLAGS += -O0 -g3 +$(call cc-option-add,CFLAGS,CC,-Og) # But allow an override to -O0 in case Python enforces -D_FORTIFY_SOURCE=<n>.
