Nicolai Haehnle 08e8cb5760 AMDGPU/MC: Add .amdgpu_lds directive ... Summary: The directive defines a symbol as an group/local memory (LDS) symbol. LDS symbols behave similar to common symbols for the purposes of ELF, using the processor-specific SHN_AMDGPU_LDS as section index. It is the linker and/or runtime loader's job to "instantiate" LDS symbols and resolve relocations that reference them. It is not possible to initialize LDS memory (not even zero-initialize as for .bss). We want to be able to link together objects -- starting with relocatable objects, but possible expanding to shared objects in the future -- that access LDS memory in a flexible way. LDS memory is in an address space that is entirely separate from the address space that contains the program image (code and normal data), so having program segments for it doesn't really make sense. Furthermore, we want to be able to compile multiple kernels in a compilation unit which have disjoint use of LDS memory. In that case, we may want to place LDS symbols differently for different kernels to save memory (LDS memory is very limited and physically private to each kernel invocation), so we can't simply place LDS symbols in a .lds section. Hence this solution where LDS symbols always stay undefined.
