Hallo,
my name is Klaus Friedrich.
For my diploma thesis, i will work with the gcc4.1 internals. I would
like to extract information about the RTL
language. I search for a description of the virtual machine/virtual
processor on the RTL instruction set and for example the register
management/alignment.
I can't find exakt information about the meaning for the RTL constructs.
For Example the meaning for this reg expression [D.1281] in
(reg:SI 58 [D.1281]) or the meaning for virtual-stack-vars in (reg/f:SI
54 virtual-stack-vars).
I also information about the (clobber (reg:CC 17 flags)) expr. What do
the clobber function with the reg 17 ?
Thank You very much!!!
Klaus Friedrich
