CONFIG_RISCV_GP¶
Enable RISC-V global pointer relative addressing
Type: bool
Help¶
Use global pointer relative addressing for small globals declared
anywhere in the executable. It can benefit performance and reduce
the code size.
Note: To support this feature, RISC-V SoC needs to initialize
global pointer at program start or earlier than any instruction
using GP relative addressing.
