Assembler Syntax

MOVGEZ ar, as, at

C Syntax

#include <xtensa/tie/xt_core.h>

extern void XT_MOVGEZ(int r /*inout*/, int s, int t);

Description

(please consult the Xtensa ® Instruction Set Architecture Reference Manual for any cross references and additional information)

MOVGEZ performs a conditional move if greater than or equal to zero. If the contents of address register at are greater than or equal to zero (that is, the most significant bit is clear), then the processor sets address register ar to the contents of address register as. Otherwise, MOVGEZ performs no operation and leaves address register ar unchanged.

The inverse of MOVGEZ is MOVLTZ.

Operation

if AR[t]31 = 0 then
	AR[r] ← AR[s]
endif
