Purpose

revamb is a static binary translator. Given a input ELF binary for one of the supported architectures (currently MIPS, ARM and x86-64) it will analyze it and emit an equivalent LLVM IR. To do so, revamb employs the QEMU intermediate representation (a series of TCG instructions) and then translates them to LLVM IR.

How to build

revamb employs CMake as a build system. The build system will try to automatically detect the QEMU installation and the GCC toolchains require to build the test binaries.

If everything is in standard locations, you can just run:

mkdir build/
cd build/
cmake ..
make -j$(nproc)
make install

For further build options and more advanced configurations see docs/BuildSystem.rst (TODO: reference).

To run the test suite simply run:

make test

Example run

The simplest possible example consists in the following:

cd build
cat > hello.c <<EOF
#include <stdio.h>

int main(int argc, char *argv[]) {
  printf("Hello, world!\n");
}
EOF
armv7a-hardfloat-linux-uclibceabi-gcc -static hello.c -o hello.arm
./translate hello.arm
# ...
./hello.arm.translated
Hello, world!
