2019-12-11arm: Fix an incorrect warning when -mcpu=cortex-a55 is used with ↵Richard Earnshaw3-28/+57
-mfloat-abi=soft When a CPU such as cortex-a55 is used with the soft-float ABI variant, the compiler is incorrectly issuing a warning about a mismatch between the architecture (generated internally) and the CPU. This is not expected or intended. The problem stems from the fact that we generate (correctly) an architecture for a soft-float compilation, but then try to compare it against the one recorded for the CPU. Normally we strip out the floating point information before doing that comparison, but we currently only do that for the features that can be affected by the -mfpu option. For a soft-float environment we also need to strip out any bits that depend on having floating-point present. So this patch implements that and does a bit of housekeeping at the same time: - in arm-cpus.in it is not necessary for a CPU to specify both +dotprod and +simd in its architecture specification, since +dotprod implies +simd. - I've refactored the ALL_SIMD fgroup in arm-cpus.in to create a new subgroup ALL_SIMD_EXTERNAL and containing the bits that were previously added directly to ALL_SIMD. Similarly, I've added an ALL_FPU_EXTERNAL subgroup. - in arm.c rename fpu_bitlist and all_fpubits to fpu_bitlist_internal and all_fpubits_internal for consistency with the fgroup bits which they contain. * config/arm/arm-cpus.in (ALL_SIMD_EXTERNAL): New fgroup.
