How does the ARM architecture differ from x86? [closed]
2013年2月10日 · The ARM architecture was originally designed for Acorn personal computers (See Acorn Archimedes, circa 1987, and RiscPC), which were just as much keyboard-based personal computers as were x86 based IBM PC models. Only later ARM implementations were primarily targeted at the mobile and embedded market segment.
Using objdump for ARM architecture: Disassembling to ARM
To disassemble arm object file use arm-linux-gnueabi-objdump. In Ubuntu, "arm-linux-gnueabi-objdump" is the default disassembler for ARM binaries - no compilation is needed. To install it, just do: sudo apt-get install binutils-arm-linux-gnueabi. There are also other binaries inside this package that can further analyze the ARM binaries for you ...
c++ - Detecting CPU architecture compile-time - Stack Overflow
2018年10月18日 · If you want a cross-compiler solution then just use Boost.Predef which contains. BOOST_ARCH_ for system/CPU architecture one is compiling for. BOOST_COMP_ for the compiler one is using. BOOST_LANG_ for language standards one is compiling against. BOOST_LIB_C_ and BOOST_LIB_STD_ for the C and C++ standard library in use.
How to detect target architecture using CMake? - Stack Overflow
2012年8月14日 · First you need to call "uname -m" to get the " machine hardware name ". Afterwards you need to cut off the trailing " Carriage Return " to get the actual Value back into the provided Variable. EXECUTE_PROCESS( COMMAND uname -m COMMAND tr -d '\n' OUTPUT_VARIABLE ARCHITECTURE )
How to set Architecture for docker build to arm64?
2017年12月14日 · In your docker file use base image with support for arm. E.g. ubuntu. Build your image with command similar to the following: docker build --platform arm --pull -t your_tag . This command will force docker to pull arm version of the base image and will also set arm architecture to your result image.
Differences between ARM architectures from a C programmer's …
2014年3月16日 · The ARM world is a bit messy. For the C programmers, things are simple: all ARM architectures offer a regular, 32-bit with flat addressing programming model. As long as you stay with C source code, the only difference you may see is about endianness and performance. Most ARM processors (even old models) can be both big-endian and little-endian ...
What registers to save in the ARM C calling convention?
32-bit ARM calling conventions are specified by AAPCS32. From the AAPCS32, §6.1.1 Core registers: r0-r3 are the argument and scratch registers; r0-r1 are also the result registers. r4-r8 are callee-save registers. r9 might be a callee-save register or not (on some variants of AAPCS it is a special register)
What are SP (stack) and LR in ARM? - Stack Overflow
From the ARM architecture reference: SP, the Stack Pointer. Register R13 is used as a pointer to the active stack. In Thumb code, most instructions cannot access SP. The only instructions that can access SP are those designed to use SP as a stack pointer. The use of SP for any purpose other than as a stack pointer is deprecated.
What is the difference between the ARM, Thumb and Thumb 2 …
2015年2月23日 · ARM has tried to create 'architecture' versions. That is the same CPUs from the same architecture version should run the same binary. A list can be found on wikipedia. An architecture is usually listed as ARMvN, where N is a number. ARMv1 to ARMv4 (approximately 1985-1998) are only ARM 32 bit ISA.
ARM vs RISC and x86 vs CISC - Stack Overflow
2022年7月13日 · ARM is one of the least RISCy, having a load-multiple instruction and complex addressing modes. But it has RISC attributes like a fixed-width machine-code format (except in Thumb mode). And being a load/store machine (ALU instructions can't have memory operands). Same for CISC being a category of which x86 is the most prominent current member.
