22.1.8.3's Apple selection omitted
addsf3,comparesf2,divsi3,mulsf3andudivsi3, which the package-wide list withholds becausebuiltins/arm/supplies them on Cortex-M. On an Apple row nothing does, and the package's own objects call them: measured on macos-15 in a consumer's link asld64.lld: error: undefined symbol: __udivsi3(fromudivmodsi4.o),__addsf3(fromsubsf3.o) and__divsi3(frommodsi3.o).The five are added under
