predef-contribute — Contribute updates or corrections of pre-defined macros

Re: [Predef-contribute] Language Standards page missing 2020+

[Bjorn R. <br...@st...>]

Hi Jim.

Thanks for the information. The predef pages have migrated to:

   https://github.com/cpredef/predef

Unfortunately SourceForge does not make it easy to redirect the old
pages to the new.

[Predef-contribute] Language Standards page missing 2020+

[Jim O'H. <joh...@gm...>]

Hello,

C and C++ have updated, thus the values of __STDC_VERSION__ and __cplusplus
have changed on the Language Standards page.

C23 is 202311
C++20 is 202002, C++23 is 202303.

Thanks for keeping this list available.

[Predef-contribute] som predef specification aditions

[<pe...@ou...>]

Hello,

I would like to suggest some changes and additions to the structure of the predefinitions in the md documents according to the manuals.


compiler CC65<http://en.wikipedia.org/wiki/Cc65>
__CC65__ is compiler identification and cpu 6502 architecture too only in CC65 compiler environment



KEIL CARM<http://www.keil.com/arm/carm.asp>/51/166
__CA__ ARM cpu architecture

__C166__ C166 cpu various manufacturers architecture

__C51__ and __CX51__ is MCS51 Intel mcu architecture

__C251__ is MCS251 Intel mcu architecture

and __KEIL__ is the compiler signature, but I haven't found it in any documentation yet, I can't say it for sure



__Z80 is Zilog Z80 cpu architecture

__Z180 is Zilog architecture too

but not Intel


I hope this helps.

Let me know your opinion

Re: [Predef-contribute] Haiku OS

[Alibek O. <a1b...@gm...>]

Hello, Carsten! Thanks for mentioning Haiku and Illumos here.

As this wiki has been moved to GitHub, I suggest you contributing your
changes there: https://github.com/cpredef/predef/
If GitHub doesn't fit you, I can add a note for them myself,
referencing this thread.

[Predef-contribute] IllumOS kernel

[Carsten J. <car...@we...>]

"#ifdef __illumos__" is how to detect IllumOS operating system kernel,
used by i.e. OmniOS or OpenIndiana.

[Carsten J. <car...@we...>]

"#ifdef __HAIKU__" is how to check for Haiku (haiku-os.org)

Re: [Predef-contribute] Please add C++20 to Language Standards

[Alibek O. <a1b...@gm...>]

Hello, Stefan!

This wiki is now maintained at GitHub: https://github.com/cpredef/predef.
Committed the change at
https://github.com/cpredef/predef/commit/901cad5bd447cd6e509401d597897e0be0c070a9

Would've added C23 and C++23 as well, but it seems they are not accepted by
the ISO yet. Not sure whether it's we should reference them.

Best regards,
Alibek.

Hello Team,

Please add ARM macros from the newer Visual Studio versions:

[Predef-contribute] some updates on predef/README.md

[xim <xi...@ds...>]

Hi,

My name is Ming Xi. The predef package from github is very helpful for 
cross-platform programming.

I added the following to predef/README.md:

1. added DataModels.md to the index.

2. added a method to grab all pre-defined macros, and so user can handle 
new-platform easier.

Please see the attachment.

Yours sincerely,

Ming Xi

[Predef-contribute] More compiler flags

[Dan F. <da...@co...>]

I've been playing with the Z88DK Z80 cross compiler environment recently and
have a few new defines to contribute.

Categorizing this compiler isn't completely straightforward.  Z88DK
(https://z88dk.org/) is a development kit that includes two cross-compilers (with
linker, assembler, etc.) standard C library, tools for building images, and
some drivers for over one hundred different Z80 computers. One compiler is
based on Small-C/Plus and the other one based on SDCC. While there are defines
for each of those >100 machines (and their variants), probably very few of them
are interesting any longer so I've just included two of them, those that could
be considered "operating systems" that ran on more than one specific machine
(MSX and the granddaddy of Z80 OSes, CP/M).

Compilers       Macro       Description

Z88DK sccz80    __SCCZ80    Using sccz80 compiler
Z88DK sccz80    SCCZ80      Using sccz80 compiler
Z88DK sdcc      __SDCC      Using sdcc compiler

Both seem to be set. They may not be Z88DK-specific, given they seem to
be spelling "Small C Compiler - Z80".

Operating Systems  Macro       Description

CP/M               __CPM     Defined by Z88DK
CP/M               CPM       Defined by Z88DK
MSX                __MSX     Defined by Z88DK
MSX                MSX       Defined by Z88DK

Architectures  Macro       Description
(These are similar enough that they could probably all be under a header "x80")

8080           __8080__    Defined by Z88DK
8085           __8085__    Defined by Z88DK; __8080__ is also defined
Z80            __Z80       Defined by Z88DK
Z180           __Z180      Defined by Z88DK

That link works for me.

That said, notice that the predef pages have been migrated to

   https://github.com/cpredef/predef/

There is a small blue box to indicated the migration on the SourceForge
