+// This pass lowers the local data store, LDS, uses in kernel and non-kernel
+// functions in module and packs them together as single allocation.
+// Packed LDS Layout is emulated in the dynamically allocated device global
+// memory.
+//
+// Replacement of Kernel LDS accesses:
+// For a kernel, LDS access can be static or dynamic which are direct
+// (accessed within kernel) and indirect (accessed through non-kernels).
+// All these LDS accesses corresponding to kernel will be packed together,
+// where all static LDS accesses will be allocated first and then dynamic
+// LDS follows. The total size with alignment is calculated. A new LDS global
+// will be created for the kernel called "SW LDS" and it will have the
+// attribute "amdgpu-lds-size" attached with value of the size calculated.
+// All the LDS accesses in the module will be replaced by GEP with offset
+// into the "Sw LDS".
+// A new "llvm.amdgcn.<kernel>.dynlds" is created per kernel accessing
+// the dynamic LDS. This will be marked used by kernel and will have
+// MD_absolue_symbol metadata set to total static LDS size, Since dynamic
+// LDS allocation starts after all static LDS allocation.
+//
+// A device global memory equal to the total LDS size will be allocated.
+// At the prologue of the kernel, a single work-item from the
+// work-group, does a "malloc" and stores the pointer of the
+// allocation in "SW LDS".
+//
+// To store the offsets corresponding to all LDS accesses, another global
+// variable is created which will be called "SW LDS metadata" in this pass.
+// - SW LDS Global:
+// It is LDS global of ptr type with name
+// "llvm.amdgcn.sw.lds.<kernel-name>".
+// - Metadata Global:
+// It is of struct type, with n members. n equals the number of LDS
+// globals accessed by the kernel(direct and indirect). Each member of
+// struct is another struct of type {i32, i32, i32}. First member
+// corresponds to offset, second member corresponds to size of LDS global
+// being replaced and third represents the total aligned size. It will
+// have name "llvm.amdgcn.sw.lds.<kernel-name>.md". This global will have
+// an intializer with static LDS related offsets and sizes initialized.
+// But for dynamic LDS related entries, offsets will be intialized to
+// previous static LDS allocation end offset. Sizes for them will be zero
+// initially. These dynamic LDS offset and size values will be updated
+// with in the kernel, since kernel can read the dynamic LDS size
+// allocation done at runtime with query to "hidden_dynamic_lds_size"
+// hidden kernel argument.
+//
+// At the epilogue of kernel, allocated memory would be made free by the same
+// single work-item.
+//
+// Replacement of non-kernel LDS accesses:
+// Multiple kernels can access the same non-kernel function.
+// All the kernels accessing LDS through non-kernels are sorted and
+// assigned a kernel-id. All the LDS globals accessed by non-kernels
+// are sorted. This information is used to build two tables:
+// - Base table:
+// Base table will have single row, with elements of the row
+// placed as per kernel ID. Each element in the row corresponds
+// to ptr of "SW LDS" variable created for that kernel.
+// - Offset table:
+// Offset table will have multiple rows and columns.
+// Rows are assumed to be from 0 to (n-1). n is total number
+// of kernels accessing the LDS through non-kernels.
+// Each row will have m elements. m is the total number of
+// unique LDS globals accessed by all non-kernels.
+// Each element in the row correspond to the ptr of
+// the replacement of LDS global done by that particular kernel.
+// A LDS variable in non-kernel will be replaced based on the information
+// from base and offset tables. Based on kernel-id query, ptr of "SW
+// LDS" for that corresponding kernel is obtained from base table.
+// The Offset into the base "SW LDS" is obtained from
+// corresponding element in offset table. With this information, replacement
+// value is obtained.
