…ehavior. Feature dit provides independent timing for data processing instructions according to the value CPSR.DIT of the Current Program Status Register. The runtime detection in FMV does not examine the content of control registers, therefore such features are not suitable for runtime dispatch since they cannot be exploited in a meaningful way. See the ACLE patch for more info: ARM-software/acle#355 Depends on llvm/llvm-project#114387
