Subject: [PATCH 4/5] exec: Define EM_RISCV for klibc builds
|
|
|
|
klibc's elf.h header doesn't define the EM_RISCV machine type
|
|
constant. Add a fallback definition when building with klibc to
|
|
support RISC-V architecture.
|
|
|
|
EM_RISCV (243) is the official ELF machine type for RISC-V as
|
|
defined in the ELF specification.
|
|
|
|
Upstream-Status: Pending
