Hi there,
New version is uploaded on Terfaspace with some bug fixes and speed increase (I hope)
JJ2007, can you please test it for speed now

regards

JJ2007, can you please test it for speed now

It has become a bit slower, sorry:
HJWasm32   : 6.3 secs->6.8
HJWasm64   : 5.2 secs->5.4

Besides, my testbed throws an exception (with both 32+64 bit versions):

Code Select Expand

  pop edx ; save return address to a global var (allocP saves edx)
  call MbAllocP ; reuse two args on stack
  push edx ; load return address and fall through to MbAddToHeapTable
MbAddToHeapTable proc
  push edx
  push ecx
  push eax ; the pointer we want to save
  sub esp, 2*16
  movups [esp], xmm0
  movups [esp+16], xmm1
  mov edx, offset MbHeapTable

Good code:

Code Select Expand

00405E4B   Ú$  5A            pop edx
00405E4C   ³.  E8 D3EDFFFF   call 00404C24
00405E51   ³.  52            push edx
00405E52   ³$  52            push edx
00405E53   ³.  51            push ecx
00405E54   ³.  50            push eax
00405E55   ³.  83EC 20       sub esp, 20
00405E58   ³.  0F110424      movups [esp], xmm0
00405E5C   ³.  0F114C24 10   movups [esp+10], xmm1              ; TestMasmBasic.00405E5C(guessed Arg1,Arg2)
00405E61   ³.  BA 30024200   mov edx, offset 00420230

Bad code:

Code Select Expand

00405E3B   Ú$  5A            pop edx                            ; TestMasmBasicHJ32.00405E3B(guessed Arg1,Arg2)
00405E3C   ³.  E8 D3EDFFFF   call 00404C14
00405E41   ³.  52            push edx
00405E42   ³$  52            push edx                           ; TestMasmBasicHJ32.00405E42(guessed Arg1,Arg2)
00405E43   ³.  51            push ecx
00405E44   ³.  50            push eax
00405E45   ³.  83EC 20       sub esp, 20
00405E48   ³.  0F110424      movups [esp], xmm0
00405E4C   ³.  0F114C24 BA   movups [esp-46], xmm1
00405E51   ³.  40            inc eax
00405E52   ³.  0242 00       add al, [edx]
00405E55   ³.  83A2 90010000 and dword ptr [edx+190], 00000000
00405E5C   ³.  0F57C0        xorps xmm0, xmm0

Hope it helps... :icon14:

Thanks JJ, I am surprised because I used VS "Favor fast code (/Ot)" option
The error is in OFFSET, which I will check tonight

Can you please test the one from page 2 in this thread and see if there is the same problem
Thanks nidud I will pay attention to those things you pointed out

[jj2007]

Can you please test the one from page 2 in this thread and see if there is the same problem

Page 2 version produces correct code.

[habran]

Thanks JJ,
That makes it easyer to find the error

[jj2007]

Can you post two identical versions, one compiled with the "favour fast code" option, the other one without?

[habran]

Here they are (fixed bug from before)
One with 'F' i the "fast" one

[jj2007]

They both choke, so the /fast option is not the culprit :(

[habran]

Please explain it in a plain English

[jj2007]

That is plain English, my friend :P

They both chokethrow exceptions, so the /fast option is not the culpritresponsible for the problem :(

[habran]

Now you are talking my language
I figure it out, the new version can not regurgitate OFFSET
I will fix that and than I will post it here

[habran]

JJ, try now above files, I replaced them with ones that work (fingers crossed ::))

[jj2007]

Both work fine :t
(the fast one is marginally slower :icon_mrgreen:)
