Floating-pointinstructions that update the condition flags
The only A32/T32 floating-point instructions that can update the condition flags are
VCMPE. Other floating-point or Advanced SIMD instructions cannot modify the flags.
VCMPE donot update the flags directly, but update a separate set of flagsin the Floating-Point Status and Control Register (FPSCR).To use these flags to control conditional instructions, includingconditional floating-point instructions, you must first update the conditionflags yourself. To do this, copy the flags from the FPSCR into theAPSR using a
VMRS APSR_nzcv, FPSCR
All A64 floating-point comparison instructions can updatethe condition flags. These instructions update the flags directlyin the NZCV register.
