remove xe_kernel_export_shim_fn field of Export function_data, trampoline is now the only way exports get invoked Remove kernelstate argument from string functions in order to conform to the trampoline signature (the argument was unused anyway) Constant-evaluated initialization of ppc_opcode_disasm_table, removal of unused std::vector fields Constant-evaluated initialization of export tables name field on export is just a const char* now, only immutable static strings are ever passed to it Remove unused callcount field of export. PM4 compare op function extracted Globally apply /Oy, /GS-, /Gw on msvc windows Remove imgui testwindow code call, it took up like 300 kb
