Due to this, 0b011 is a 2-bit value because tablegen will happily drop leading zeroes on integers. I propose that we change this, and store binary literals with a size. I think this is much more natural, as when the user writes a value with 3...

Hi All, I started to work on code-size improvements on ARM target by comparing GCC and LLVM generated code. My first candidate was switch-case lowering. I also created a Bugzilla issue for this topic: https://bugs.llvm.org/show_bug.cgi?id=34902 The full example code and the generated assembly for GCC and for LLVM is in the Bugzilla issue. My first idea was to simplify the following
