- Subject: Target specific attributes to variables
Hi,
We are implementing attributes to variables. The attribute of the
operand is checked and the respective instructions are emitted based
on the attributes. We have added the attribute to one addressing mode
in which the operand is absolute memory (SYMBOL_REF). This was
implemented by checking the tree value using the macro SYMBOL_REF_DECL.
Even though the other 2 addressing modes are implemented, the
attributes could not be checked in the other 2 modes. These 2 modes
are "disp with register" and "register indirect" addressing modes. The
tree structure in these addressing modes could not be checked for
attributes using the RTX of the operand. We were unable to get any
information from other target specific attributes.
Any help/suggestions in solving the problem will be highly appreciated.
Regards,
Naveen.H.S.
