Right now, clang is missing several features that I care about, but most of the industry doesn&#x27;t[1].  Clang is a 90% or maybe 95% solution, and my use cases aren&#x27;t covered.  So I don&#x27;t use it.  That said, I am grateful for the competition: GCC has definitely been getting better thanks to clang.<p>[1] Namely, -Wdouble-promotion, big-endian ARM interrupt handlers, -fstack-usage, -Og, -fno-delete-null-pointer-checks, -falign-functions
