cmd/go: add GORISCV64 environment variable
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.
Fixes #61476
