C Syntax

#include <xtensa/tie/xt_hifi2.h>

extern void AE_LA32X2_RIP(ae_int32x2 d /*out*/, ae_valign uu /*inout*/, const ae_int32x2 * a /*inout*/);

Description

AE_LA32X2.RIP loads two 32-bit, potentially uanligned values from memory into the AE_DR register. It forms a virtual address using the address register.

The load instruction reads two, 32-bit values from memory. The data is placed in the AE_DR register d, swapping the two 32-bit values.

The base address is post-decremented by 8.
