Considering -feliminate-unused-debug-types is the default according to the GCC
docs, why don’t we remove DEBUG_FLAGS entirely to remove a level of
indirection? It’s not a huge amount of copy-paste as we can set
FULL_OPTIMIZATION = "-O2 -pipe ${DEBUG_PREFIX_MAP} ${DEBUG_LEVELFLAG}”
DEBUG_OPTIMIZATION = "-Og -pipe ${DEBUG_PREFIX_MAP} ${DEBUG_LEVELFLAG}”
(also, why is -pipe an optimisation flag?)
I was also thinking a less invasive solution would be to do this in llvm.bb:
DEBUG_FLAGS:append = "${@d.getVar(oe.utils.vartrue('DEBUG_BUILD', '', ‘-g0',
d))}”
