Subject: [PATCH] RISC-V: Handle R_RISCV_CALL_PLT reloc
|
|
|
|
GNU assembler starting 2.40 release always generates R_RISCV_CALL_PLT
|
|
reloc for call in assembler [1], similarly LLVM does not make
|
|
distinction between R_RISCV_CALL_PLT and R_RISCV_CALL [2].
|
|
|
|
Fixes "grub-mkimage: error: relocation 0x13 is not implemented yet.".
