Arithmetic Expression Compiler

[FlatAssembler]

Anyway, here is an example of how conditional operators and string constants (things I've added to AEC recently) can make the code significantly shorter:

Code:

AsmStart
   debug=0
    macro pushIntToStack x
    {
        sub esp,4
        fld dword [x]
        fistp dword [esp]
    }
    macro pushPointerToStack x
    {
        sub esp,4
        lea ebx,[x]
        mov [esp],ebx
    }
    macro pushStringToStack x
    {
        sub esp,4
        mov dword [esp],x
    }
    format PE console
    entry start

    include 'win32a.inc'

section '.text' code executable
    start:
    jmp enterNumber$
        enterNumber db "Enter the ordinal number of the month.",10,0
    enterNumber$:
    pushStringToStack enterNumber
    call [printf]
    pushPointerToStack month
    jmp floatSign$
        floatSign db "%f",0
    floatSign$:
    pushStringToStack floatSign
    call [scanf]
AsmEnd
If month=2
    enterTheYearString<="Enter the year:",10,0
    AsmStart
        invoke printf,enterTheYearString
        pushPointerToStack year
        pushStringToStack floatSign
        call [scanf]
    AsmEnd
    If mod(year,4)=0 & not(mod(year,400)=0)
        days:=29
    Else
        days:=28
    EndIf
ElseIf mod(month,1)=0 & month>0 & month<13
    days:= month=1? 31 : month=3? 31 : month=4? 30 : month=5? 31 : month=6? 30 : (month=7 | month=8)? 31 : month=9? 30 : month=10? 31 : month=11? 30 : 31
Else
    invalidDateString<="Next time you open this program, please enter a natural number between 1 and 12.",10,0
    AsmStart
        invoke printf,invalidDateString
        invoke system,_pause
        invoke exit,1
    AsmEnd
EndIf
numberOfDaysString<="The month with that ordinal number has %d days.",10,0
AsmStart
    pushIntToStack days
    invoke printf,numberOfDaysString
    invoke system,_pause
    invoke exit,0

    _pause db "PAUSE",0

section '.rdata' readable writable
    result dd ?
    month dd ?
    days dd ?
    year dd ?

section '.idata' data readable import
    library msvcrt,'msvcrt.dll'
        import msvcrt,printf,'printf',system,'system',exit,'exit',scanf,'scanf'
AsmEnd

That dragitz who forked my repository on GitHub apparently won't cooperate with me any more. But, anyway, I've introduced a few hard-to-fix problems in my code by adding new features. First of all, the AST diagrams that are produced for ternary operators are next to useless. Second, perhaps even more damaging, there is a [url=https://github.com/FlatAssembler/Arithme...r/issues/1]bug[/url] that prevents my implementation of QuickSort to be compiled using the newest version of the compiler (HybridSort and MergeSort are unaffected), and it's not easy to fix. I've chosen a fundamentally wrong method of compiling long ago and it would take very long to think of a better algorithm and implement it.
