These tell the linker to generate GNU_IFUNC relocs that rewrite the
PLT entries in the user's address space to point to our resolved GL
function, so there's no extra function pointer. It also, as a bonus,
cuts 400k out of the library.
This requires a toolchain from 2010 or so. Unfortunately, it's going
to take a bit more investigation to find out what specific bits are
required.
Fixes#4
The story about how we came to needing GetProcAddress functions isn't
that interesting, but the featureset is something that should be
(particularly when comparing to similar tools that exist).
Fixes#7
Previously, these lines were using '>' which is the Markdown syntax
for a "blockquote", but within this, the '#' in "#include" was still
interpreted as a header, (which was not desired), and throwing away
the rest of the line.
It seems that a "codeblock" is what is wanted here instead, (which
should result in un-interpreted text wrapped in <pre>). Markdown
expects 4-space indent for this.
