GCC 14.2.1 available from ARM web site

[Giovanni]

Hi,

Just ran tests using GCC 14, it worked without surprises, no performance improvements to report in usual ChibiOS benchmarks. GCC 13 is still perfectly fine unless you need some of the new features.

For the ultimate edgers I have compiled 15.0.1_experimental for ubuntu 24.04 : https://drive.google.com/file/d/1i6P6pFENXAkXFkslHCBC7RD-G5yBI3Ow/view?usp=drive_link

In short : ChibiOS compile fine, static analyzer don't complain. g++15 trigger some error messages due to real bugs in my code that g++14.2 compiled happily.

° c23 #embed is supported
° more C++23/26 support
° C++20 modules support

and probably more.
Of course, for tests only, gcc15.1 release is due for April or May.

hello,
gcc 16.1 is out.
the cross compiler for linux ubuntu24 is here :

A big revision for the C++ frontend with c++26 things, but on the C side, almost nothing (I find the _Countof macro that return the number of elements of an array)

It compiles Chibios project with -fanalyzer static analyzer without complaining.
