CPUID functions

Here are some functions, along with a batch file, showing how to determine
whether your processor supports certain instruction sets;

Code: 
@setlocal
@echo off
function SSE=`%@winapi[cpuid,SSE_IsSupported]`
function SSE42=`%@winapi[cpuid,SSE42_IsSupported]`
function MMX=`%@winapi[cpuid,MMX_IsSupported]`
function HTT=`%@winapi[cpuid,HTT_IsSupported]`

iff %@SSE[] eq 1 then
   echo Your Processor Supports SSE
else
  echo Your Processor Does Not Support SSE
endiff

iff %@SSE42[] eq 1 then
  echo Your Processor Supports SSE42
else
  echo Your Processor Does Not Support SSE42
endiff

iff %@MMX[] eq 1 then
  echo Your Processor Supports MMX
else
  echo Your Processor Does Not Support MMX
endiff

iff %@HTT[] eq 1 then
  echo Your Processor Supports HTT
else
  echo Your Processor Does Not Support HTT
endiff
endlocal
This works on;

Code: 
TCC 11.00.39 Windows XP [Version 5.1.2600]
TCC Build 39 Windows XP Build 2600 Service Pack 3

CPUID

THIS FAILS mainly because it has no DLL specified atlas cpuid is not a known DLL on my
system.

CPUID

I simplified the BTM to when it only reports:

--- code ---
@echo off
setlocal
echo Your Processor Supports SSE: %@if[%@winapi[cpuid,SSE_IsSupported]
EQ 1,yes,no]
echo Your Processor Supports SSE42: %@if[%@winapi[cpuid,SSE42_IsSupported]
EQ 1,yes,no]
echo Your Processor Supports MMX: %@if[%@winapi[cpuid,MMX_IsSupported]
EQ 1,yes,no]
echo Your Processor Supports HTT: %@if[%@winapi[cpuid,HTT_IsSupported]
EQ 1,yes,no]

--- end code ---

However, it fails here as well with the message "The specified module could
not be found" - "cpuid".

Software Environment:
TCC 11.00.40 Windows XP [Version 5.1.2600]
TCC Build 40 Windows XP Build 2600 Service Pack 3

Hardware (from %_cpu): AMD Athlon(tm) XP 2100+ - x86 Family 6 Model 6
Stepping 2(Athlon XP) @ 1733 MHZ - Palomino/Corvette

Well, I've got that DLL on three of my systems, and have been calling it from some PowerBASIC Programs I've written.

It's dated 12/20/2009, is 6,144 bytes in size, and has no entries in the summary fields. It only has those four functions.

I have a feeling I may have written it, but darned if I can find the source code for it!:confused:

I did find the source code for a CPUID.EXE, which has similar functions, which I was working on last December, on exactly that date. It should not be too difficult for me to re-create the DLL.

Sorry for the confusion.:o

Well, I found the source code, nicely backed up on my NAS Drive.

I've compiled the PowerBASIC code, and have attached the DLL.

Again, sorry for the confusion.:o

It would appear that I'm starting to get mighty forgetful in my old age.:(

I did find in the comments the link to the Intel Docs I was working from, if anyone is interested in the details.

Inasmuch as you (and only you) have the source code, you might just make it
into a plug-in DLL, defining four internal variables (which can be evaluated
once during the loading of the plug-in, since the hardware won't change),
using the usual 0 / 1 values:
_SSE_Supported
_SSE42_Supported
_MMX_Supported
_HTT_Supported

Joe,

Since you had to create a DLL for this function anyway, why not make it a
plugin instead? That way you don't have to create FUNCTION's on top of
the DLL.

There are a number of ways you could implement the plugin's interface.
Here are a few that come to mind:

1) create variables for each "thing" :
_SSE_Supported
_SSE42_Supported
_MMX_Supported
_HTT_Supported

2) Create a function similar to how @SHFOLDER works:
@CPUID[index]
index can be:
0 - SSE Supported
1 - SSE42 Supported
2 - MMX Supported
3 - HTT Supported
4 - HW Virtualization Supported
5 - etc.

For option 2 you'd use it like:
if %@cpuid[0] == 1 (echo SSE Supported) else (echo SSE not
supported)

an accessible ftp or http URL?
