Hi,

Did I miss how to set the ELF HIDDEN symbol attribute?

There's no such setting in fasm, but the macro-based implementation in fasm2 should be easy enough to extend. Just modify the "public?" macro to accept more options, or make a copy of the macro with another name for making such symbols and replace STT_FUNC/STT_OBJECT with STT_HIDDEN there (you also need to add the definition of STT_HIDDEN itself, which was not present in the old specification that this formatter was originally based on).

Huh, I forgot to mention fasmg, but I guess I'll move to fasm2.

That said, github.com is getting worse at being friendly with noscript/basic (x)html browser to display code text (it is not even showing, I have to git clone to browse the code... but hey, what did I expect from microsoft github...).

The formatter macros that come with fasm2 are just updated fasmg macros, you can still use the previous packages if you prefer.
