Replace all uses of sysroot_candidates with get_or_default_sysroot

2025-06-05T16:54:10+00:00

Before this change we had two different ways to attempt to locate the sysroot which are inconsistently used: * get_or_default_sysroot which tries to locate based on the 0th cli argument and if that doesn't work falls back to locating it using the librustc_driver.so location and returns a single path., * sysroot_candidates which takes the former and additionally does another attempt at locating using librustc_driver.so except without linux multiarch handling and then returns both paths., The latter was originally introduced to be able to locate the codegen backend back when cg_llvm was dynamically linked even for a custom driver when the --sysroot passed in does not contain a copy of cg_llvm. Back then get_or_default_sysroot did not attempt to locate the sysroot based on the location of librustc_driver.so yet. Because that is now done, the only case where removing sysroot_candidates can break things is if you have a custom driver inside what looks like a sysroot including the lib/rustlib directory, but which is missing some parts of the full sysroot like eg rust-lld.

And consistently use try_canonicalize rather than canonicalize.

Cache current_dll_path output

2025-03-21T12:46:24+00:00

Computing the current dll path is somewhat expensive relative to other work when compiling `fn main() {}` as `dladdr` needs to iterate over the symbol table of librustc_driver.so until it finds a match.
