I'm not sure what you have in mind. The command `clang -target arm-none-gnueabi foo.s -mllvm -mattr=+no-neg-immediates` does not seem to work for me. Am I missing something?
Also, this <http://lists.llvm.org/pipermail/llvm-dev/2016-May/099026.html> seems to suggest that I shouldn't be using this construct.
As this is not really a "feature" of the architecture, so a modifier to `-march` (like `-march=armv8+dsp`) doesn't make sense.
Note also that `-mno-neg-immediates` also affects inline assembly, so it makes sense as a compiler option.
