- ios - Are armv8 and arm64 the same? - Stack Overflow
Basically the 32-bit armv8-A instructions are called AArch32 and are fully compatible with ARMv7-A (32-bit), armv8-A is not the same as arm64 since this refers specifically to the AArch64 instructions contained within the armv8-A instruction set See the image above
- What is my architecture and what does armv8l exactly means?
ARMv8-A CPUs are supposed to support both modes, so such a chip effectively gives you two architectures in one Generally arm or aarch32 refers to the 32-bit mode, and arm64 or aarch64 for the 64-bit mode The armv8l mode in uname means your kernel is built to run on an ARMv8 chip in its
- What new instructions does ARMv8-M Baseline provide over ARMv6-M?
In 2016, ARM introduced the ARMv8-M architecture as an upgrade to the popular ARMv6-M (Cortex M0 M0+ M1) and ARMv7-M (Cortex M3 M4 M7) architectures The ARMv8-M architecture is again split into a Baseline profile seen as a continuation of the ARMv6-M architecture and a Mainline profile seen as a continuation of the ARMv7-M architecture
- Differences between arm64 and aarch64 - Stack Overflow
Then in October 2011 the ARMv8-A spec added a new 64-bit execution state called "AArch64", retroactively renaming the old 32-bit architecture "AArch32" Then to add a bit more confusion, in 2017 the company rebranded from being called "ARM" (an acronym for "Advanced RISC Machines") to just "Arm"
- ARMv8 - Running legacy 32-bit applications on 64-bit OS
For something like a Linux application, then yes ARMv8-A includes AArch32, which provides backwards compatibility with ARMv7-A There are some limitations, such as the SWP instruction no longer being supported But these are types of things that applications are unlikely to be using (and were deprecated in ARMv7)
- gcc - How to install the aarch64 toolchain for armv8 cortex-a53 on . . .
It does not support ARMv8 64-bit code armhf code will run just fine on the cortex-a53 CPU (in 32-bit mode), but if you want to run 64-bit ARMv8 code in Linux, you'll need to get a Linaro-supported ARM64 system (e g Dragonboard410c) or wait for Raspbian to be updated with support for 64-bit ARM –
- How to build GCC toolchain that supports ARMV8M
I need to build this GCC toolchain with certain cxx flags to disable verbose exceptions I need this toolchain to mainly support building code for Cortex M33 ARMV8 architecture I have tried using the following config options
- Compiling on ARMv8 - Running on ARMv7 - Stack Overflow
Is it possible to compile a Package on ARMv8 and run it on ARMv7 ? That's called cross-compiling and is the usual way how ARM code is generated – only that most build machines for ARM binaries are probably x86_64 nowadays But if you have a compiler that targets platform ARMv7 running on ARMv8, I don't see a problem
