In CompileJvm.gmk, I'd replace
- ASFLAGS := $(JVM_ASFLAGS), \
+ ASFLAGS := $(JVM_ASFLAGS) $(EXTRA_ASFLAGS), \
with adding EXTRA_ASFLAGS to JVM_ASFLAGS right after where JVM_LDFLAGS is
finalized, vis
JVM_LDFLAGS += \
$(SHARED_LIBRARY_FLAGS) \
$(JVM_LDFLAGS_FEATURES) \
$(EXTRA_LDFLAGS) \
#
+
+ JVM_ASFLAGS += ${EXTRA_ASFLAGS)
That way, uses of EXTRA_xxFLAGS are all in one place and possible future
file-specific assembler flags don't have to duplicate adding EXTRA_ASFLAGS.
Otherwise, good.
