intmem
This is a small header-only C++11 library that helps loading unaligned integers from memory, in natural/little/big endian.
It has been tested under the following platforms:
- GCC 8.2 and Clang 6.0 under Linux/x32, Linux/x64 and Linux/mipsbe (using QEMU).
- Windows x32 and x64 using Visual Studio 2015
Tests
The tests.cpp file can be compiled to run tests:
$ c++ tests.cpp -std=c++11 -O2 -o tests
$ ./testsIf everything goes fine, the process returns 0 and print the message All
tests are OK..
One way to test big-endian support on x86 computers is to cross-compiling for MIPS under Debian, and run it using QEMU user mode:
$ sudo dpkg --add-architecture mips && sudo apt update
$ sudo apt install qemu-user qemu-user-binfmt clang-6.0 libstdc++-8-dev:mips binutils-mips-linux-gnu
$ clang++-6.0 -target mips-linux-gnu -O2 tests.cpp -std=c++11 -o tests
$ ./tests
