while not cx16.mouse_pos() should give error

ConstantFoldingOptimizer (after merging master):

after(numLiteral..) : check that cast to/from BOOL is not done??

VM 6502 what
|
|
===== ====== =======
|
|
ok . boolean const
|
|
ok . boolean variables value, boolean subroutine param
|
|
ok . static bool var (block scope) with initializer value (staticVariable2asm)
|
|
ok . boolean arrays value, list and single value
|
|
ok . return boolean value from sub
|
|
ok . logical not, and, or, xor work correctly, also inplace
|
|
ok . make sure that and,or,xor,not aren't getting replaced by the bitwise versions in the Ast
|
|
ok . and, or, xor, not should work in expressions: print_ub((bb and true) as ubyte)
|
|
ok . bitwise logical ops on bools give type error, including invert
|
|
ok . arithmetic ops on bools give type error
|
|
ok . logical ops on ints give type error
|
|
ok . boolean values in ubyte array should give type error
|
|
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 . while booleanvar==42 and do..until booleanvar==42 should give type error
|
|
ok . while not <integervar> should give type error
|
|
ok . while not <integer functioncall> should give type error
|
|
ok . while boolean should produce identical code as while integer!=0
|
|
ok . while not boolvar -> can we get rid of the cmp? (6502 only?)
|
|
ok . if someint==0 / ==1 should stil produce good asm same as what it used to be with if not someint/if someint
|
|
ok . efficient code for manipulating bools in an array (normal and agumented assigns)
|
|
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.
|

|
|
boolean trick to go from a compare >= value, to a bool
|
|
cmp #value
|
|
rol a
|

and #1

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
