If I understand correctly. Isn't your suggestion synonymous with
WITHOUT_CROSS_COMPILER?
So far as I know, devel/llvm* builds make no use of WITHOUT_CROSS_COMPILER
definitions ( documented in src.conf ) or what I mention below (also from
src.conf documentation).
As for what is analogous in src.conf's documentation for system
builds: BE_NATIVE in an devel/llvm* for a given context would be
analogous to using a specific mix of:
WITHOUT_LLVM_TARGET_AARCH64 vs. WITH_LLVM_TARGET_AARCH64
WITHOUT_LLVM_TARGET_ARM vs. WITH_LLVM_TARGET_ARM
WITHOUT_LLVM_TARGET_MIPS vs. WITH_LLVM_TARGET_MIPS
WITHOUT_LLVM_TARGET_POWERPC vs. WITH_LLVM_TARGET_POWERPC
WITHOUT_LLVM_TARGET_RISCV vs. WITH_LLVM_TARGET_RISCV
WITHOUT_LLVM_TARGET_X86 vs. WITH_LLVM_TARGET_X86
Some of the mixes would simulate the various devel/llvm* ports
BE_NATIVE's intent for various platforms. (BE_NATIVE does not
work in all contexts, last I tried it anyway.)
Ahh. My mistake I guess. I somehow got the idea that defining
WITHOUT_CROSS_COMPILER caused llvm to build only what's needed
build/bootstrap for the arch it's (currently) running on. Which
would, of course. Slim down the buildtime/installed footprint.
Thanks for the clarification, Mark.
