Vineet Gupta 31aefa93f3 ARC: fp: (micro)optimize FPU_STATUS read by eliding FWE bit clearing ... Any FPU_STATUS write needs setting the FWE bit (31) whcih just provides a "control signal" to enable explicit write (vs. the side-effect of FPU instructions). However this bit is RAZ and write-only, thus effectively never stored in FPU_STATUS register. Thus when reading the register there is no need to clear it. This shaves off a BCLR instruction from the fe*exceptino family of functions and while no big deal still makes sense to do. This came up when debugging a race in math/test-fenv-tls [1] [1]: https://github.com/foss-for-synopsys-dwc-arc-processors/linux/issues/54 Signed-off-by: Vineet Gupta <vgupta@synopsys.com>		2021-07-21 13:13:44 -07:00
