--- Comment #8 from Ramana Radhakrishnan <ramana at gcc dot gnu.org> --- Author: ramana Date: Mon Jan 19 14:55:28 2015 New Revision: 219847 URL: https://gcc.gnu.org/viewcvs?rev=219847&root=gcc&view=rev Log: Improve documentation of register constraints. While looking at PR target/64532- I realized we haven't documented all the register constraints. I'm not documenting the other immediate constraints as it is not clear to me how much of that is actually useful yet and I don't have the time this afternoon to clean this up. Built documentation and looked at it. Applied. Ramana Modified: trunk/gcc/ChangeLog trunk/gcc/doc/md.texi
