- Subject: PRE_DEC, POST_INC
Hi,
I am working on a new port.
The target machine supports post-increment and pre-decrement
addressing modes. These modes are twice faster than indexed mode.
It is important for us that GCC consider them well.
I wrote emails to gcc-help and I was told that GCC was not so good at
pre/post-dec/increment since few targets support these modes.
I would like to know if there is a good way to make pre-dec and
post-inc modes have more priority than indexed mode.
Is there current work for dealing with this issue ?
Thank you.
Regards.
Florent
