The Embedded-C spec introduces a number of C language features useful for embedded development. GCC already implements fixed point arithmetic (Chapter 4) from this proposal.
http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1169.pdf Chapter 5 is divided into two sections: named address space support and named-register storage classes. IBM has an implementation of named address space support on the named-addr-spaces-branch that we would like to merge into mainline. Before proceeding, I would like to discuss what would be acceptable to the GCC community. Our implementation only covers section 5.1 of the proposal (named address space support). Section 5.2 has not been implemented. I am conscious that the named address space implementation we have is not sufficiently generic to be acceptable for mainline and will need to be cleaned up before being submitted. In addition, there is no support for nested address spaces and that is arguably a deficiency of any implementation of this proposal. Would this be acceptable, provided that this limitation is documented? Thanks, Ben
