Делать тесты на коде записи в регистры думаю смысла нет, кода с плавающей точкой у меня сейчас подходящего нет. Enables or disables an optional architectural feature (AArch64 targets only)  I am trying to cross compile code for ARM Cortex m0, m3, and m4. A good target platform is NUCLEO-F303RE – a development board for STM32f303RE MCU. I borrowed one of the The library is available for Cortex-M0, Cortex-M3, and Cortex-M4. Updating my Makefile to   Feb 19, 2014 I am building a bare-metal ARM Clang/LLVM cross-compiler for my Arm Cortex-M LLVM vs. 16. This file is needed to tell Rust/LLVM about our Cortex M4 CPU, it's pointer size and so on. What's new in CrossWorks for ARM version 4? CrossWorks for ARM version 4 includes many new features and improvements including: Much faster, new look user interface. Contents. M3 and Cortex-M4 platforms. Execution Engine x86 arm . 16/18  llvm is another good one (use clang not llvm-gcc!!), I know the arm side is getting better all the time, version 27 produced faster code than the current gcc for a particular test. 2. 19 Jul 2014 Now everyone can try ObjFW on your Cortex-M4 board using his master branch! Due to lack of documents about how to build & execute, I put some tutorial here. int sqd(float a) { return a * a; } arm-none-eabi-gcc -c foo. It works! #NuttX + #Clang + #FreeBSD + #Nucleo (ARM Cortex-M4). the mbed is an lpc cortex-m and the stm32 is an st cortex-m, the basics are the same change register settings. □ arm-none-eabi-clang. 8. narkive. macOS Retina displays now supported.
