This enables +iASL to disassemble some AML that may have been compiled using older +versions of iASL that no longer compile with newer versions of iASL. + +iASL: Fixed the required parameters for _NIH and _NIG. Previously, there +was a mixup where _NIG required one parameter and _NIH required zero +parameters. This change swaps these parameter requirements. Now it is +required that _NIH must be called with one parameter and _NIG requires +zero parameters. + +iASL: Allow use of undefined externals as long as they are protected by +an if (CondRefOf (...)) block when compiling multiple definition blocks. + +iASL: Fixed the type override behavior of named objects that are declared +as External. External declarations will no longer override the type of +the actual definition if it already exists. + +AcpiNames: Added setargv.obj to the MSVC 2017 link sequence to enable +command line wildcard support on Windows. Note: the AcpiNames utility is +essentially redundant with the AcpiExec utility (using the "namespace" +command) and is therefore deprecated. It will be removed in future +releases of ACPICA. + +Disassembler: ignore AE_ALREADY_EXISTS status when parsing create* +operators. The disassembler is intended to emit existing ASL code as-is. +Therefore, error messages emitted during disassembly should be ignored or +handled in a way such that the disassembler can continue to parse the +AML. This change ignores AE_ALREADY_EXISTS errors during the deferred Op +parsing for create operators in order to complete parsing ASL termlists. + +iASL DataTable Compiler: IVRS table: fix potentially uninitialized +variable warning. Some compilers catch potential uninitialized variables. +This is done by examining branches of if/else statements.
