Debugging and JIT issues

copse · 31 March 2012, 10:48

Hi,

Windows 7 Home Basic, 64 bit. WinUAE 2.4.0 (just updated thanks!). Workbench 39.29, KS 3.17. AsmOne v1.49-RC2.

When I debug within AsmOne with the JIT enabled, the debugging does not behave properly. What this means, I am not sure. The debugger just does not seem to accept debugging commands past the point at which something goes wrong in JIT-land. AsmOne itself is perfectly responsive. The code below reproduces the problem.

When I debug within AsmOne without the JIT enabled, the debugging works fine.

I'd also like to note that AsmOne is a lot faster with 2.4.0 than with the preceding version. Well done Toni, I admire your productivity and the way you persevere with WinUAE.

This code reproduces the problem when I enter the debugger, and then step $100 instructions.

Code:

	SECTION	programrs000000,CODE
ProgStart
	movem.l	D1-D6/A0-A6,-(SP)
	movea.l	A0,A2	;argv
	move.l	D0,D2	;argc
	lea	bar,A4	;Start of data section.
	movea.l	4,A6
	lea	foo,A3
	moveq	#0,D1
	move.l	#$9F,D0
	bra.s	_su_StartClearLoop

_su_ClearLoop	move.l	D1,(A3)+
_su_StartClearLoop	dbra	D0,_su_ClearLoop

	movem.l	(SP)+, D1-D6/A0-A6
	rts

foo:	dcb.b $FF, 0
bar:	dcb.b $10, 0

Enable "Hard flush" in the "Advanced JIT Settings" and Asm-One's debugger will work fine.

It may work fine but note that JIT and any debuggers are totally unsupported.

That's no problem. Could you possibly share the reason for this? It would be interesting to know why.

Another debugging bug, with JIT disabled and for good luck "more compatible" enabled. This happens in both AsmOne and AsmPro, due to unexpectedly being in supervisor mode (if I recall all this stuff correctly from years ago) so SP points to SSP rather than USP.

And the WinUAE debugger:

I'll try StingRay's suggestion and see if that makes a difference.
