sold is a linker software which links a shared objects and its depending shared objects. For example,

% ldd libhoge.so
    libfuga.so (0x00007fb6550b2000)
% sold -i libhoge.so -o libhoge2.so
% ldd libhoge2.so
%

sold works only for shared objects not for executables. Sorry.

• master: I am developing on this branch.
• stable: Stable version of master for our internal use.

sold works only on Linux on x86-64 and aarch64 architectures.

git clone https://github.com/akawashiro/sold.git
cd sold
mkdir -p build
cd build
cmake ..
make

Now you can see the sold in build directory.

sold -i [INPUT] -o [OUTPUT]

Options

• --section-headers: Emit section headers. Output shared objects work without section headers but they are useful for debugging.
• --check-output: Check integrity of the output by parsing it again.
• --exclude-so: Specify a shared object not to combine.

renamer is software to rename symbols in shared objects. You can rename symbols in shared objects like the following.

% cat mapping
hoge fugafuga
% renamer libhoge_original.so --output libhoge_renamed.so --rename-mapping-file mapping

Just same as sold.

renamer [INPUT] --output [OUTPUT] --rename-mapping-file [MAPPING]

All lines in [MAPPING] must be a space separated pair of the old name of a symbol and the new name.

Please run "./run-format.sh" before merging to master branch.

• Executables
• TLS in executables
  • Initial exec and local exec
• x86-32
• Test Fedora linux in CI

The purpose of this test is to check sold can preserve the complex ABI.
