How to use fancy 18Fxxxx indexing?

[BadBrainBoy]

I'm trying to write fast code for the 18F2220. It has three nice auto-incrementing indirect memory pointers, the INDFx and FSRx registers. But when I use constructs like x = *pRead++; I find that the compiler produces dumb code without the autoindexing, and only uses one of the pointer registers. My application has three queues, it would be perfect for using the three pointer registers with autoincrementing. Is there some way to make this happen, short of assembly coding? I have PCH version 3.190.

Thanks!

If you can update your compiler, do so but it still may not take advantage of the newer addressing modes. I haven't checked.

It may be necessary to in-line the asm code yourself, especially if you can't update your compiler.

You can always address the registers in C without resorting to asm. Now you will have to try the ++,-- operations on the INDF regs to see if CCS optimizes them and uses the 18's instructions.
