Through the ABI names, we reserve some of these registers for certain purposes. For example, all registers that start with a t for temporary can be used for any purposes. Se hela listan på ocf.berkeley.edu 1.2.1Stack Pointer Register In RISC-V architecture, the x2 register is used as Stack Pointer (sp) and holds the base address of the stack. When programming explicitly in RISC-V assembly language, it is mandatory to load x2 with the stack base address while the C/C++ compilers for RISC-V, are always designed to use x2 as the stack pointer.

RISC-V on kärbitud käsustik (RISC), mille arendusega alustati 2010. aastal. RISC-V on avatud standard ning selle spetsifikatsioon on avalikult saadaval vastavalt Creative Commons litsentsile. Käsustiku litsents lubab igaühele luua implementatsiooni ilma litsentsitasu maksmata, ka ärieesmärgil. Käsustikku arendab RISC-V Foundation.

Table 26.1, Chapter 26 RISC-V Assembly Programmer’s Handbook, in the RISC-V base specification, 2019-06-08 ratified). That means before calling a function the caller has to save all caller saved registers to the stack if it wants to retain their content. 2019-09-07 · Risc-V works hard to define as few instructions as possible. As a result some instructions have multiple uses. For instance ADDI is add an intermediate to a register, which is of the form: ADDI RD, RS, imm. Where RD is the destination register, RS the source register and imm is a 12-bit immediate value.
