Nobody expects the Red Teamv3
Too many changes to list, but broadly:
* Remove Intel GPU support from the compiler
* Add AMD GPU support to the compiler
* Remove Intel GPU host code
* Add AMD GPU host code
* More device instructions. From 40 to 68
* More host functions. From 48 to 184
* Add proof of concept implementation of OptiX framework
* Add minimal support of cuDNN, cuBLAS, cuSPARSE, cuFFT, NCCL, NVML
* Improve ZLUDA launcher for Windows

+// PTX linking rules are fairly convoluted. Here's my understanding:
+// * For normal data (.global, .const) and non-kernel functions (.func)
+// * Symbol occurences must be equivalent under following rules:
+// * For data, symbol occurences must be of the same size. Alignment is ignored
+// * For functions, symbol occurences are strictly type-checked.
+// Number, type and alignmnt of input and return parameters must all match
+// * There are 3 classes of directives:
+// * Declarations. Only valid on functions
+// .func foobar();
+// * Definitions (complete definitions). Either data or functions
+// .func foobar() { ret; }
+// .global foobar .u32;
+// Both .global and .const are *always* initialized. If no explicit
+// initializer is present, they are zero-initialized
+// * Incomplete definitions. Data definitions using incomplete type. Only
+// known incomplete type is an array with at least one zero dimension
+// .extern .global foobar .b8 [];
+// Incomplete definitions *must* have an .extern linking specifier
+// * There can be only one definition (normal or incomplete) of a symbol
+// in a module
+// * There can be multiple declarations of a symbol in a module
+// * Declarations must all be the same: same linking specifier,
+// same argument list, same return list
+// * Data (.global and .const) is alwas accessible by cuModuleGetGlobal(...),
+// no matter the linking specifier. So this definition:
+// .global .u32 foobar1[1] = {1}
+// is not visible to othe modules during linking, but is accessible
+// by CUDA runtime after linking
+// * Non-kernel functions are never accessible by cuModuleGetGlobal(...)
+// * There are are four linking specifiers:
+// * (empty): static linking, a symbol is only visible inside a module
+// * For functions; separate functions with the same name in multiple, separate modules behave as expected
+// * For data, compiler selects the first symbol with the given name for access from cuModuleGetGlobal(...)
+// * This is only allowed linking specifier for local globals (globals defined inside function body),
+// which are not visible through cuModuleGetGlobal(...)
+// * .extern: means that symbol is completely-defined strictly in another module.
+// If the same symbol is completely-defined in the same module it's an error
+// It's legal to not resolve the declaration if it's unused
+// .extern is legal for:
+// * declarations and incomplete definitions
+// * normal definitions if all are true:
+// * it's a data definition
+// * it's a non-linking compilation
+// * initializer is not present
+// * .visible: symbol is strong (overrides .weak) and globally visible.
+// Multiple .visible symbol occurences during linking compilation are illegal
+// * .weak: symbol is weak and globally visible.
+// If there's no strong symbol occurence, first weak symbol occurence gets selected
+// * .common: symbol is strong (overrides .weak) and globally visible with some additional rules:
+// * applies only to .global
+// * selects the first occurence from the largest symbol occurences
+// * explicit initializer is only allowed on symbol occurences with the largest size

+ PTX represents dynamically allocated shared local memory as

+ This pass looks for all uses of .extern .shared and converts them to

+ The question is how this artificial argument should be expressed. There are
+ several options:
+ * Straight conversion:
+ .shared .b32 shared_mem[]
+ * Introduce .param_shared statespace:
+ .param_shared .b32 shared_mem
+ or
+ .param_shared .b32 shared_mem[]
+ * Introduce .shared_ptr <SCALAR> type:
+ .param .shared_ptr .b32 shared_mem
+ * Reuse .ptr hint:
+ .param .u64 .ptr shared_mem
+ This is the most tempting, but also the most nonsensical, .ptr is just a
+ hint, which has no semantical meaning (and the output of our
+ transformation has a semantical meaning - we emit additional
+ "OpFunctionParameter ..." with type "OpTypePointer Workgroup ...")
