Summary: When identifing instructions that can be folded into a MOVCC instruction, checking for a predicate operand is not enough, also need to check for thumb2 function, with restrict-IT, is the machine instruction eligible for ARMv8 IT or not. Notes in ARMv8-A Architecture Reference Manual, section "Partial deprecation of IT" https://usermanual.wiki/Pdf/ARM20Architecture20Reference20ManualARMv8.1667877052.pdf "ARMv8-A deprecates some uses of the T32 IT instruction. All uses of IT that apply to instructions other than a single subsequent 16-bit instruction from a restricted set are deprecated, as are explicit references to the PC within that single 16-bit instruction. This permits the non-deprecated forms of IT and subsequent instructions to be treated as a single 32-bit conditional instruction."
