It's a lot more stable. What is stack?

jj2007 · « **Reply #16 on:** May 18, 2022, 02:11:03 AM »

stack equ dword ptr [esp]
stack[4] = first argument
etc

But must be edi-10

jj2007 · « **Reply #18 on:** May 18, 2022, 02:19:01 AM »

Correct

(wow, somebody reads and understands my code

I can read my own code! _{(most of the time )}

Hi Hector,

Here is a console program using mostly CyCt* macros plus one of the MichaelW counters:

YMMV

But in general, I get fairly consistent output, and at much, much greater speed. Which is an argument when you are trying to optimise an algo and it takes you many small changes.

jj2007 · « **Reply #23 on:** May 19, 2022, 07:29:53 PM »

More refining done... it starts to look convincing

Can I have some timings, please?

Here is the civilised version, with an Inkey at the end. The other one runs fine from a DOS prompt, of course

hutch-- · « **Reply #26 on:** May 19, 2022, 09:13:15 PM »

This onje at least stops on the inkey but to run it, it must be copied to my dev drive. Would be a lot easier to run if I could just copy windows.inc to where it gets unzipped. I test on a ramdrive, not my dev drive.

Now I understand the problem

I know one guy who is very proud about all paths in include files being hardcoded to the root as in \thatfolder\whatever

Let esi=FileRead$("\Masm32\include\Windows.inc")
Attached a version with embedded Windows.inc, and some more timings. Don't complain that it's a fat attachment

Thanks, Steve, now it looks reasonably stable

A typical usage example:

Code: [Select]

	CyCtStart
		fldpi
		fmul FP4(100.0)
		fistp testDD
	CyCtEnd PI*100
	CyCtStart
		fldpi
		fmul FP4(100.0)
		fdiv FP4(10.0)
		fistp testDD
	CyCtEnd PI*100/10
	CyCtStart
		push eax
		pop eax
	CyCtEnd push & pop eax
