Hi,

I have written a proc_macro (which makes use of std) and am currently trying to compile some code that uses this macro.
However I get a bunch of errors when trying to compile for thumbv6m-none-eabi, it looks like this is because it does not have support for std.

My confusion comes from the fact that this toy example which uses the macro is completely no_std, only the macro makes use of std.
Am I compiling this incorrectly or is it not possible to compile for some target (that does not have support for std) while some macro code depends on std?
