This is a default setting on arm64/aarch64. When set, these options are also in effect: WITHOUT_SYSTEM_COMPILER (unless WITH_SYSTEM_COMPILER is set explicitly) I'm curious about: A) Why there is a bias to avoid the system compiler? and by contrast: B) What sort of context justifies explicitly setting WITH_SYSTEM_COMPILER when WITH_LLD_IS_LD is in use? === Mark Millard markmi at dsl-only.net
