Apr 25, 2012 · To build .c/.cpp file with NEON support add .neon suffix to filename (for example: file.cpp.neon) in Android.mk file. Or to build all files with NEON enabled, put into Android.mk file: LOCAL_ARM_NEON := true Be careful - not all ARMv7 devices support NEON (like Nvidia Tegra 2). Better detect it at runtime and choose different codepath then.

Using the GNU Compiler Collection (GCC): ARM Options. ... Additionally, the following architectures, which lack support for the Thumb execution state, ... This is because NEON hardware does not fully implement the IEEE 754 standard for floating-point arithmetic (in particular denormal values are treated as zero), so the use of NEON instructions ...

GCC and armcc support the same intrinsics, so code written with NEON intrinsics is completely portable between the toolchains. There are no specific command line options required for the compiler to process NEON …

I would like to ask which version of gcc and with what flags , may I compile some c code to assembly code that uses arm neon coprocessor for ARMV7-A processor. Of course I want to use the processor itself but also the coprocessor. Is this gcc optimal? Thank you

The Neon Programmer's Guide for Armv8-A provides more information about Neon intrinsics and Neon programming in general. Building Note: For NDK r21 and newer Neon is enabled by default for all API levels. If you need to disable Neon to support non-Neon devices (which are rare), invert the settings described below.

GNU ARM → GNU MCU Eclipse! The GNU MCU/ARM Eclipse project is currently under migration to the Eclipse Foundation as Eclipse Embedded CDT (C/C++ Development Tools). Starting with Eclipse plug-ins v4.x, the project was enhanced with support for RISC-V devices, thus the new MCU name, more appropriate for a multi-platform project. For more details, see the RISC-V Corner and xPack GNU …
