Broken patch
I hit the following limit twice: "macros cannot be nested more than 20 levels
deep" (one time with a tail-recursive macro and another with generated code).
This refers to assembly macros, in lib/MC/MCParser/AsmParser.cpp .
I would be very nice to have a command-line option to be able to increase this
limit in those (uncommon) cases.
I tried to make a patch (attached), but it is not working: the command line
option is not used (and I get the "argument unused during compilation"
warning).
I am unfamiliar with LLVM code-base so I unfortunately do not know how to fix
the issue with my patch.</pre>
