Thanks Pelle,

Very informative.  I had no idea that 5GigHz was the max turbo speed of my 'travel laptop'. 
Windows only reports the leisurely 1.7GHz.

A very tiny, partial sample, of one of the output sections of the program to spark interest.

Thanks. Maybe it can lead to something more, some day.

Hi Pelle,

Nice addition to the toolbox of Pelles C coders, thanks.

User contributions / SMBIOS info

Nothing fancy, just a program I wrote last year to dump info about my BIOS settings (to the console).
Incomplete in many ways. Maybe useful to someone...?

OK. I still don't see the point in having a tool that combines object files, but never mind. Not important.

Simple printf emulator using only the bare percentage symbol to represent strings :

Code Select Expand

.386
.model flat,stdcall
option casemap:none

includelib \PellesC\lib\Win\kernel32.lib
includelib \PellesC\lib\Win\user32.lib

ExitProcess PROTO :DWORD

printfX PROTO C format:DWORD,args:VARARG

.data

format1 db 'This is a % % to % %',0
str1    db 'printfX',0
str2    db 'demo',0
str3    db 'type',0
str4    db 'strings.',0

.code

start:

    invoke   printfX,ADDR format1,
             ADDR str1,ADDR str2,
             ADDR str3,ADDR str4
             
    invoke   ExitProcess,0

END start

Hi Pelle,

The purpose of merging object modules is to provide only one monolytic object file to the linker. Nothing fancy. As you said, it's preferable to create a static library.

but... when is this useful??

I can only think of two things to do with an object file:
1) pass it to the linker
2) put in in a library/archive, and pass that to the linker

I mean, normally you have the source code, and anything of importance that needs to change in the object file is better handled by editing the source code and rebuild.
If you don't have the source code, well... disregarding any legal issues, if you don't known exactly what you are doing, random changes will probably cause more harm than good (and don't expect tools at this level to warn you much).

As suggested by TimoVJL,
replacing

malloc(...)with

aligned_alloc(16, ...)works for me...

Thomas, I have already spent a fair amount of time investigating this problem. I'm still looking for a proper solution. This is going to take some time...
