TODO ==== check all comparisons for split word arrays (signed+unsigned, all 4 variants) snow example is a lot larger! explore possible optimizations for words when comparing to a constant number (BeforeAsmAstChanger) add tests for comparison that do an assignment rather than an if assign to variable, and barray[indexvar], test if they're both correct (bb = value > -100 --> contains a beq +++ that shouldn't be there??) optimize assignOptimizedComparisonWords for when comparing to simple things like number and identifier. optimize optimizedPlusMinExpr for when comparing to simple things like number and identifier. optimize the IfElseAsmgen's fallbackTranslate even more (for arrays without const index for example?) ===== ====== ======= VM 6502 what ===== ====== ======= ok ok boolean const ok ok boolean variables value, boolean subroutine param ok ok static bool var (block scope) with initializer value (staticVariable2asm) ok ok boolean arrays value, list and single value ok ok return boolean value from sub ok ok logical not, and, or, xor work correctly, also inplace ok ok make sure that and,or,xor,not aren't getting replaced by the bitwise versions in the Ast ok ok and, or, xor, not should work in expressions: print_ub((bb and true) as ubyte) ok ok swap operands around on evaluating staticboolvar xor ba[0] ok ok bitwise logical ops on bools give type error, including invert ok ok arithmetic ops on bools give type error ok ok logical ops on ints give type error ok ok boolean values in ubyte array should give type error ok ok type error for bool[3] derp = 99 and also for init value [1,0,1] and also for [true, false, 1, 0, 222] ok ok while booleanvar==42 and do..until booleanvar==42 should give type error ok ok while not should give type error ok ok while not should give type error ok ok while not cx16.mouse_pos() should give condition type error ok ok efficient code for manipulating bools in an array (normal and agumented assigns) ok ok efficient code for if with only a goto in it ok ok efficient code for if byte comparisons against 0 (== and !=) ok ok efficient code for if word comparisons against 0 (== and !=) ok ok efficient code for if float comparisons against 0 (== and !=) ok ok efficient code for if byte comparisons against a value ok FAIL efficient code for if word comparisons against a value ok ok efficient code for if float comparisons against a value ok ok efficient code for assignment byte comparisons against 0 (== and !=) ok ok efficient code for assignment word comparisons against 0 (== and !=) ok ok efficient code for assignment float comparisons against 0 (== and !=) ok ok efficient code for assignment byte comparisons against a value ok ok efficient code for assignment word comparisons against a value ok ok efficient code for assignment float comparisons against a value ok ok efficient code for if_cc conditional expressions ok ok while boolean should produce identical code as while integer!=0 and code should be efficient ok ok while not boolvar -> can we get rid of the cmp? (6502 only?) ok ok testmonogfx works ok . check program sizes vs. master branch ===== ====== ======= check that the flood fill routine in gfx2 and paint still works. re-allow typecast of const true/false back to ubytes 1 and 0? re-allow typecast of const ubyte 0/1 to false/true boolean? IR: add TEST instruction to test memory content and set N/Z flags, without affecting any register. replace all LOADM+CMPI #0 / LOAD #0+LOADM+CMP+BRANCH by this instruction
