Hi all,
I've recently read the changelog of the newlib standard library and have started to ask myself if Arm runs the test suite provided with newlib on some ARM target hardware before embedding the prebuilt library into a compiler release. Where can I find details about that?
How did I come here? In the changelog of newlib I read about "fixes to powf" in "Major changes in newlib version 4.5.0" in the NEWS file caught my attention.
I've tried to understand what this means and whether it affects calculations on ARM Cortex-M7. I've recently posted to the newlib mailing list (https://sourceware.org/pipermail/newlib/2025/021787.html) but as the details are related to ARM hardware and testing for ARM the arm Community forum might be a better (or second) place to ask.
I am currently using Arm GNU Toolchain 11.3.rel1 (released on 08.08.2022) for an ARM Cortex-M7 based uC which seems to ship a prebuilt newlib/newlib-nano. I am linking with newlib-nano.
Cheers,Matthias
