When you build your program for code coverage (-ftest-coverage -fprofile-arcs),

GCC to, presumably either under control of a command line option or possibly a
configure time option, to initialize such data at run-time instead of
compile-time?
How is this distinct to having to support regular C code such as:
int x = 5;
? (I'm guessing the simplest solution would be to post-process the
statically linked image to do some kind of run-length compression on its
.data section and squirrel that away somewhere that a decompressor can
find it early on)
