While I don't see a 1% regression, I did notice a measurable code size increase when building CSiBE for thumb-2 and -Os. It's hard to put my finger on what is causing this, beyond the fact that the compiler is making more use of 'high' registers and this results in using more 32-bit rather than 16-bit instructions.
