Re: Arithmetic bug on ARM (STM 32 F4)

Hi, I cannot run make check because of the cross-compilation. I also noticed that the GMP function "mpz_probab_prime_p" fail when GMP is built with the latest versions (after 7) of gcc-arm-none-eabi. Titouan Coladon Le 22/01/2021 à 12:33, Vincent Lefevre a écrit : > Hi, > > On 2021-01-22 11:5

Re: Arithmetic bug on ARM (STM 32 F4)

I think so to, but I currently don't have time for this. Looking for bugs on this kind of target is quite time consuming... I'm not an expert in bare-metal programming and was basically just verifying that my code runs on a STM32F4 board. Le 22/01/2021 à 13:44, Vincent Lefevre a écrit : > On 20

Re: Arithmetic bug on ARM (STM 32 F4)

Thanks for your answer, it's indeed, gcc that must have a bug. The older bare metal version: gcc-arm-none-eabi-7-2017-q4-major-linux is working properly. Then the latest version : gcc-arm-none-eabi-8-2018-q4-major-linux, gcc-arm-none-eabi-9-2020-q2-update-x86_64-linux and gcc-arm-none-eabi-10-20
