[Tinycc-devel] Questions about backend writing

[yazgoo]

Hi,

I'd like to try and write a backend for TCC.
Is there more documentation than:
http://bellard.org/tcc/tcc-doc.html#SEC34 ?

More precisely, I'd be interested in knowing:

1. how load and store functions work, especially why in my tests I always have a store call after a load call;

2. if it is possible to use a custom assembler and how to do so;

3. how to use labels to call functions (if it is the good way);

4. what the following warning means:
"../main.c:16: warning: internal compiler error: vstack leak? (4)"

Regards
