Purpose
revng 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, revng employs the QEMU intermediate
representation (a series of TCG instructions) and then translates them to LLVM
IR.
How to build
revng 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!
