Hi; for the M-profile floating point work I'm going to need I think three new TB flags (to control whether to generate the code to do the various independent things the pseudocode ExecuteFPCheck() function does before executing any FP insn). Unfortunately we currently have only 2 unused bits in the arm TB flags word.
I can see two possible ways to get the 3rd bit: (1) overload the meaning of an existing bit which I know isn't relevant to M-profile (eg the XSCALE_CPAR or VECLEN or VECSTRIDE bits) (2) start defining new bits in the currently-unused cs_base word Any preferences ? thanks -- PMM
