Buggy firmware when compiling with GCC-ARM version 12 about tinysa

[DiSlord]

I think this related to gcc speed optimisation, TinySA code critical to execute timings and can depend from how compiler optimise code
Most of warnings related to ChibiOS low level code

Erik uses gcc version 7.2.1 (see below), I have gcc version 8.3.1. Is version 9 the latest "good" version for tinySA? I see that 12.x works well for NanoVNA.

Version: tinySA_v1.4-96-gc1fcd94
Build Time: May 11 2023 - 08:41:39
Kernel: 4.0.0
Compiler: GCC 7.2.1 20170904 (release) [ARM/embedded-7-branch revision 255204]

Difficult to answer, as I test code generation for NanoVNA, gcc last v9 provide more compact code. After code size bigger but not chage size, up to v12

Also as I see v7 (code build by Eric) more bigger then my builded in v9. And need test how gcc v9 code work on Tiny (several wait delays hardcoded and depend from how fast code)
