The variable represents the RISC-V user-mode application profile for which to compile. Valid values are rva20u64 (the default) and rva22u64. Setting GORISCV64=rva20u64 defines the riscv64.rva20u64 build tag, sets the internal variable buildcfg.GORISCV64 to 20 and defines the macro GORISCV64_rva20u64 for use in assembly language code. Setting GORISCV64=rva22u64 defines the riscv64.rva20u64 and riscv64.rva22u64 build tags, sets the internal variable buildcfg.GORISCV64 to 22 and defines the macro GORISCV64_rva22u64 for use in assembly language code. This patch only provides a mechanism for the compiler and hand-coded assembly language functions to take advantage of the RISC-V extensions mandated by the application profiles. Further patches will be required to get the compiler/assembler and assembly language functions to actually generate and use these extensions.
