	While the GCC and Clang compilers already define __ASSEMBLER__ automatically when compiling assembler code, __ASSEMBLY__ is a macro that only gets defined by the Makefiles in the kernel. This is bad since macros starting with two underscores are names that are reserved by the C language. It can also be very confusing for the developers when switching between userspace and kernelspace coding, or when dealing with uapi headers that rather should use __ASSEMBLER__ instead. So let's now standardize on the __ASSEMBLER__ macro that is provided by the compilers. This is almost a completely mechanical patch (done with a simple "sed -i" statement), with one comment tweaked manually in the arch/loongarch/include/asm/cpu.h file (it was missing the trailing underscores).

2024-03-11	objtool/LoongArch: Implement instruction decoder	Tiezhu Yang
	Only copy the minimal definitions of instruction opcodes and formats in inst.h from arch/loongarch to tools/arch/loongarch, and also copy the definition of sign_extend64() to tools/include/linux/bitops.h to decode the following kinds of instructions: (1) stack pointer related instructions addi.d, ld.d, st.d, ldptr.d and stptr.d (2) branch and jump related instructions beq, bne, blt, bge, bltu, bgeu, beqz, bnez, bceqz, bcnez, b, bl and jirl (3) other instructions break, nop and ertn See more info about instructions in LoongArch Reference Manual: https://loongson.github.io/LoongArch-Documentation/LoongArch-Vol1-EN.html Co-developed-by: Jinyang He <hejinyang@loongson.cn> Signed-off-by: Jinyang He <hejinyang@loongson.cn> Co-developed-by: Youling Tang <tangyouling@loongson.cn> Signed-off-by: Youling Tang <tangyouling@loongson.cn> Signed-off-by: Tiezhu Yang <yangtiezhu@loongson.cn> Signed-off-by: Huacai Chen <chenhuacai@loongson.cn>
