Question

The official documentation here only lists the minimum required version for a very small number of attributes:

http://gcc.gnu.org/onlinedocs/gcc/Function-Attributes.html

Is there a complete list of which version each attribute was added in? Even better would be a list that also shows which ones are compatible with pcc and tcc.
