This isn't how attributes are normally used. They are normally used for
changing how variables/functions are defined, and how we emit RTL to
access them.
There is no guarantee that tree info for variable declarations will
still be accessible when converting RTL insns to assembly. There is
also the problem that the optimizer can do various things to memory
load/store instructions. There may not be a one-to-one correspondence
between loads and variables, and hence no guarantee that you have a
usable mem_expr. If you need something special here, it really needs to
be done when the RTL is emitted, not when the assembly is emitted.
Yes. I agree on your point that attributes may not be valid after optimizations.
Can you please tell me how to get these attributes while emitting RTL? My
requirement is, need the newly introduced attributes while doing memory access.
Thanks in advance,
