[PATCH] D68391: [RISCV] Improve sysroot computation if no GCC install detected

[Edward Jones via Phabricator via cfe-commits]

edward-jones added a comment.

Before falling back to returning the empty string this first looks for a directory with the triple name up one level from the driver.

This uses the Triple string in the path, however this Triple has been normalized so even if the user specifies "clang --target=riscv32-unknown-elf", it will use "riscv32-unknown-unknown-elf" when looking for the sysroot. I am wondering whether it would be sensible to do a more "intelligent" search for the sysroot here by iteratively stripping "unknown"s from the triple.
