[sdcc-devel] Dissection of a compiler - undocumented function modifiers

[Jan W. <we...@ef...>]

I have still not succeeded in compiling SDCC, so I decided that from time to time I continue browsing the sources for snippets of wisdom.
I thought SDCC.lex would be a good point to start, as it is supposed to contain all the keywords one can come accross. I can then check them in the documentation and elsewhere throghout the code.
Just starting, I've found two stange function modifiers: _overlay (or __overlay) and _JavaNative.

The latter appears to be valid only for the DS390 target and is documented (well, sort of...) in TININative.txt so we can forget it.

However, the former seems to be active both in mcs51 and hc08 target, and appers to interact with the nooverlay option and pragma - shouldn't that be mentioned in the user documentation?

PS. This sort of "browsing" may result in further suggestions to the _user_ documentation - shall I post them here? (I will post the enhancements to "dissection" documentation to the wiki and crosspost here as the wiki automatic notification does not work).
