Details

(Keywords: meta)

Currently libxul has over 300 global constructors on Linux, as counted by

% nm obj-x86_64-pc-linux-gnu/dist/bin/libxul.so | grep _GLOBAL__sub -c
358

It would be nice to investigate if some of those could be removed, as global constructors are triggered on library load, which slows it down.

The clang flag -Wglobal-constructors can be used to easily track those.
