sh-generic: add CPU capabilities for optimized SH4 code On sh-generic targets, the headers <bits/cpucap.h> (in C) and <bits/asm/cpucap.h> (in assembler) provide definitions to acces the __cpucap symbol which provides information on the CPU. Currently, a single capability __CPUCAP_SH4ALDSP is defined; it represents the SH4 extended instructions together with the integrated DSP instructions. The main uses of this capability are [movua.l] (unaligned reads) and [ldrc] (built-in tight loops). Capabilities are initialized to 0 (their safest default) and the runtime can enable them based on what hardware is running. 2021-05-23 15:31:01 +02:00			`#ifndef __BITS_ASM_CPUCAP_H__`
