.FOR built in JWasm

OK JJ2007,
LET$ me PUT$$$ the question in other words:
FOR$$$ example where is the source of LET%&%$#@ say "MbPrint   PROTO"
or "MbCopy   PROTO :DWORD, :DWORD, :DWORD" ? ;)

[habran]

thanks Frank
that's what are friends for
as you can see we can even tell a joke with a good programming
that is what I call a beautiful programming 8)

OK JJ2007,

You mean the one that allows strange things such as

        Let My$(1,ecx)="This is Masm32: "+FileRead$("http://www.masm32.com")+CrLf$+My$(ecx,1)
        FileWrite "test.txt", NoTag$(My$(ecx, ecx))

?? Caution, it's pure Masm

[habran]

No, I just made a point that you are hiding your "pure MASM" like a serpent its legs ;)
however, I am not interested to study any 32 bit source code, even if it is a BASIC(!@#$%^&*),
because I don't do any more 32 bit, I do only pure 64 bit :t

[jj2007]

No, I just made a point that you are hiding your "pure MASM" like a serpent its legs ;)

The macros are open anyway - \Masm32\MasmBasic\MasmBasic.inc

And the superfast algos are closed source because I don't want to pass my time chasing my intellectual babies all over the place, especially not in some obscure C libraries

Those who have contributed over time are properly credited, and if somebody who made a significant contribution asks me for the source, I will share it with that person. Privately

[habran]

That's what I pointed out
How can we admire your beautiful masm when all we see is BASIC($&@/!?%#¥€£~^*)

did you think that I was sleeping these few day :icon_eek:
if you did, you were wrong
I have worked on optimization of this and look what I have got now:

Code: [Select]

option win64:0
OPTION PROLOGUE:NONE
OPTION EPILOGUE:NONE

xmemcpy PROC dest:QWORD,src :QWORD, count:UINT_PTR
  mov rax,rcx
  .if (rcx != rdx)
    .for (¦r8¦r9b=[rdx],[rcx]=r9b,rcx++,rdx++,r8--)
    .endfor
  .endif
  ret
xmemcpy ENDP
OPTION PROLOGUE:PrologueDef
OPTION EPILOGUE:EpilogueDef

0000000140034220  and         r8,r8

0000000140034236  ret             
if you don't put r8-- last you get and r8,r8:

I will test it a little bit more before I post it here

I have uploaded the new version at the beginning of this topic
this new optimization is for counting down to zero
it can be written as single like this "¦ var ¦"  or this "¦ var > 0¦"

I have not changed only this but I changed the concept of whole routine
so that now behaves exactly as C "for" command 

[habran]

small bug fixed and uploaded new version 8)
hll.c added line 1394:

Code: [Select]

else hll->codelines = NULLC;    //there is nothing after the second '¦'the var hll->codelines was not cleared if there was nothing after second '¦'
