* Add shader debug print opcode that uses NonSemantic DebugPrintf extension * small correction for flags in Inst * Fix IR Debug Print. Add StringLiteral op * add missing microinstruction changes for debugprint * cleanup. delete vaarg stuff. Smuggle format string in Info and flags * more cleanup * more * (dont merge??) update sirit submodule * fix num args 4 -> 5 * add notes about DebugPrint IR op * use NumArgsOf again * copyright * update sirit submodule * fix clangformat * add new Value variant for string literal. Use arg0 for fmt string * remove string pool changes * Update src/shader_recompiler/ir/value.cpp Co-authored-by: TheTurtle <47210458+raphaelthegreat@users.noreply.github.com> --------- Co-authored-by: TheTurtle <47210458+raphaelthegreat@users.noreply.github.com>
