Well if you ever get bored, you could start on LIDATA support for OMF ;-)

That's a strange suggestion. OMF is mainly used for DOS - 32-/64-bit Windows uses COFF format. Also, the virtually only benefit from supporting LIDATA is that the object module may become smaller - not really THAT important in times where HDs may usually store TBs.

A true progress would be to support COMDATs ...

MASM64 SDK / Re: Installing the Masm64 SDK

Ah I see, I understand the function of those functions now. So seems like the error that I mentioned here occurs when I trigger the makeit.bat file.

guga
ask your favorite AI can you explain how the LUT are computed using the "Harmonized Parabolic Synthesis" for the power function?

Harmonized Parabolic Synthesis is a hardware-efficient methodology for approximating mathematical functions, including the power function. It combines Parabolic Synthesis with Second-Degree Interpolation to achieve high precision and low complexity. By using multiple intervals to approximate a mathematical expression, it can calculate functions like the inverse square root within a unit in the last place (ULP), according to DiVA portal.

Lol - there aren't any differences - I'm just a grumpy old fart with limited time, so it would be nice if things were just "easy" haha :)

Well if you ever get bored, you could start on LIDATA support for OMF ;-)
I've been looking into it for a while to learn, but I don't know where to start as I don't have experience with open source development. The relevant code (which is still based on WASM) is rather intimidating for me, TBH.

MASM64 SDK / Re: Installing the Masm64 SDK

Last post by zedd - May 19, 2025, 11:29:14 PM

This tells you how far MASM64 has to go, qeditor only has the option to assemble a project, not assemble and build.

That is what "&Makeit.bat" is for. It runs a batch file in the project folder that compiles the resource file, assembles and links... Of course the user must make their own batch file named "makeit.bat" and it must be in the same path as the source file. And the project must be on the same drive\partition as the masm64 installation.

From the file "menus.ini" in the Masm64 SDK installation...

[&Project]
Assemble 64 Bit Module,\masm64\bin64\assemble.bat {b}  ; assembles asm source only
-
&Makeit.bat,makeit.bat "{b}"  ; build project with batch file: "makeit.bat"
-
&Run Program,"{b}.exe"      ; run the executable

Pelle's C compiler and tools / win32-doc md files

Last post by TimoVJL - May 19, 2025, 08:58:02 PM

Not useful for local help

MS Win32 help files in md-format.

Test program just open zip-file and check all md-files for "api_name:" keywords.

At first might be better just to extract one folder and zip it again for testing.

One full test 58416 files.

Keyword test for first keyword in file

OK, tried a thrash test by clicking Populate Control over and over until something broke...
First, all OK, then maybe 20 or so clicks later rows were added with no text, later (another 20 clicks?) the column headers' text disappeared, eventually

Lot of source files was removed after 2022-02-24 with good reason.
