Describe the bug
When building my application with the 14.2 zephyr SDK, the image size of my binary (same code) increases with about 18kB in comparison with the 13.2 zephyr SDK.
I've made 2 rom reports from both sdk's and can see most of the extra size is from following symbols which are added:
│ ├── __aeabi_cdcmpeq 16
│ ├── __aeabi_cdrcmple 32
│ ├── __aeabi_d2iz 100
│ ├── __aeabi_dadd 1444
│ ├── __aeabi_dcmpeq 12
│ ├── __aeabi_dcmpge 18

│ ├── __multiply 352
│ ├── __pow5mult 184
│ ├── _ctype_ 257
│ ├── _dtoa_r 3124
most added symbols are listed, but not all.
I'm building for an ARM target (STM32L010RB) with zephyr release 3.0.0 + some custom patches
i've build with zephyr release 3.1.0 and the same increase was noticeable.
Logs and console output
i have 2 logfiles of the rom reports, i don't want to put them public, but you can request them on a personal base.
Environment (please complete the following information):
- OS: Linux
- zephyr sdk 14.2
- zephyr 3.0.0 ( https://github.com/wcappelle/zephyr/tree/latest_main_with_own_patches )
Additional context
Maybe good to mention that logging is disabled in my configuration.
I see the following symbols have a big increase with the latest sdk
│ ├── _svfprintf_r 5160 (before:512)
│ ├── _vfiprintf_r 2148 (before:628)
