[llvm-commits] [PATCH] llc : fix PR2426 : -mcpu=help or -mattr=help requires a module to load

[Arnaud de Grandmaison]

Fix with comments from Duncan.

Simplification of previous patch : when users asks for -mcpu=help or
-mattr=help, no module is loaded at all (from stdin or file).

Without this patch, an input module is expected on stdin if no module
argument was specified. This forces the user to type CTRL+D to get the
requested help : this is not user friendly nor intuitive.

Cheers,
