In commit 64f863baeedc8659 we implemented the v8.1M FPCXT_S register, but we got the write behaviour wrong. On read, this register reads bits [27:0] of FPSCR plus the CONTROL.SFPA bit. On write, it doesn't just write back those bits -- it writes a value to the whole FPSCR, whose upper 4 bits are zeroes. We also incorrectly implemented the write-to-FPSCR as a simple store to vfp.xregs; this skips the "update the softfloat flags" part of the vfp_set_fpscr helper so the value would read back correctly but not actually take effect. Fix both of these things by doing a complete write to the FPSCR using the helper function. Backports 7fbf95a037d79c5e923ffb51ac902dbe9599c87f |
