study-arm-assembly

Study of Arm assembly language

Environment

• qemu-arm version 4.2.1
• QEMU emulator version 4.2.1
• gcc-arm-linux-gnueabi 9.4.0/10.5.0
• Target architecture: Armv8-A (Cortex-A family)

Docker container

Docker container: study-arm-assembly with qemu environment can run by run_docker.sh.

• A base Docker image: study-arm-assembly:latest is built if it doesn't exist.

• Execute commands specified by its argument.

  $ ./run_docker.sh "echo hello"
  hello
  $

  When the commands doesn't be specified, launch bash with interactive mode.

  $ ./run_docker.sh
  ubuntu@cd5a87163a62:/workspace$

Build and run

A specific C source file can be built with Makefile at the project root.

The source file specified with a Makefile variable: SRC is built and an executable binary (***.elf) is output into build directory.

# @Project root
$ make SRC=intro/addvalues/addvalues_inline.c
arm-linux-gnueabi-gcc -Wall -Wextra -Wpedantic -march=armv8-a -marm intro/addvalues/addvalues_inline.c -o build/addvalues_inline.elf

Build and execute the binary with qemu by make run.

# @Project root
$ make run SRC=intro/addvalues/addvalues_inline.c
arm-linux-gnueabi-gcc -Wall -Wextra -Wpedantic -march=armv8-a -marm intro/addvalues/addvalues_inline.c -o build/addvalues_inline.elf
addvalues = 3
