Peter Maydell a72c744370 target/arm: Refactor M-profile VMSR/VMRS handling ... Currently M-profile borrows the A-profile code for VMSR and VMRS (access to the FP system registers), because all it needs to support is the FPSCR. In v8.1M things become significantly more complicated in two ways: * there are several new FP system registers; some have side effects on read, and one (FPCXT_NS) needs to avoid the usual vfp_access_check() and the "only if FPU implemented" check * all sysregs are now accessible both by VMRS/VMSR (which reads/writes a general purpose register) and also by VLDR/VSTR (which reads/writes them directly to memory) Refactor the structure of how we handle VMSR/VMRS to cope with this: * keep the M-profile code entirely separate from the A-profile code * abstract out the "read or write the general purpose register" part of the code into a loadfn or storefn function pointer, so we can reuse it for VLDR/VSTR.
