aleclearmind Force linking of all the original libraries
Certain libraries linked to the input executable sometimes are not
required by the executable or other dynamic libraries. Therefore, the
`ld -l` switch ignores them.

This commit forces linking of all the required libraries, no matter
what, by wrapping the list of dynamic libraries in `-Wl,--no-as-needed`
and `-Wl,--as-needed`.

README.rst

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!
You can’t perform that action at this time.
