[PATCH] D70116: [RISCV] add subtargets initialized with target feature

[Sam Elliott via Phabricator via llvm-commits]

lenary added a comment.

We definitely want to support `rv32imafc/ilp32` and combinations like that.

At some point we're going to have to reckon with the fact that the ABI is described globally in the resulting object file, so cannot really be modelled on a per-function basis.

I think you're right that the solution for the moment is to pass `-target-abi` down to LTO, but only for RISC-V targets. We can work out what else we need to do for LTO once we're at that point.
