LLVM "supports" integer types of arbitrary size, NPOT ones tend to have surprising, inefficient behavior, and really large ones tend...
LLVM supports integers types of arbitrary size (e.g. i12345). Can I somehow utilize that from C/C++ when using Clang? No uint12345_t afaict.

to outright crash less-popular backends that said, I think bitfields can be used to that effect. didn't @spun_off show 33-bit ints?

Not as far as I know, since that would require interaction with LLVM IR.

where do you get those from? I know you can get i65 from some sort of integer promotion in loop optimizer

Swift used to use i21 for chars and various small bit sizes for enum tags, but we gave up after constantly dealing with backend breakage

Weird int sizes also drop you out of fastisel so are bad for debug build performance
