Alex Crichton ed938f08a9 rustc: Attempt to handle super long linker invocations ... This commit adds logic to the compiler to attempt to handle super long linker invocations by falling back to the `@`-file syntax if the invoked command is too large. Each OS has a limit on how many arguments and how large the arguments can be when spawning a new process, and linkers tend to be one of those programs that can hit the limit! The logic implemented here is to unconditionally attempt to spawn a linker and then if it fails to spawn with an error from the OS that indicates the command line is too big we attempt a fallback. The fallback is roughly the same for all linkers where an argument pointing to a file, prepended with `@`, is passed. This file then contains all the various arguments that we want to pass to the linker. Closes #41190		2017-09-05 21:07:02 -07:00
