Hi people,
I added an attribute "far" for the i386, this attribute takes one
argument, the segment register.
This attribute is intended to be use with pointers.
There is something I'm not sure about
Once the attribute handler has returned NULL_TREE without setting
no_add_attr to true, the atribute is added in the ssa tree but how to
handle this attribute after ?
I must check and handle this attribute when gcc writes the .S file
therefore in print_operand_address().
My problem is that print_operand_address use and rtx structure and not
a tree one and
I don't really understand how to access the attribute set up in the
tree in the rtx struct.
The patch for TLS model which uses %gs uses UNSPEC_TP and added some code in
ix86_decompose_address() to check for an UNSPEC code. ok but in the
same time there
is some patterns defined in i386.md for UNSPEC and if I do the same,
I'll probablty end up
by modifying most of the patterns of the file to handle a new UNSPEC
for the attribute.
It seems to be too ugly so I was wondering if there is another way to do it.
Thanks.
Have a great day.
