I've finally had a spare minute or three to put together a gcc-3.4.0 tree on my CVS server as well as to update it and my gcc-3.3.3 tree to produce better code, and am looking for beta testers to try it out, *especially* anyone who is using a 5407 and the -m5407 flag to the toolchain. 1) I've added to both gcc-3.3.3 and gcc-3.4.0 trees modifications to add: 1) register offset addressing so the compiler generates 'move.[bwl] d16(Ax),(d16)Ay instead of move.[bwl] d16(Ax),Rx;move.[bwl] Rx,d16(Ay)' 2) Code to use the new instructions mov3q/mvs/mvz for ColdFire V4 3) Code to convert and/or/xor into bclr/bset/bchg for single bit manipulations. 4) Code to use 'cmp.[bw]' instructions for ColdFire V4 5) A fix for the infamous 'move.b <ea>,Ax' bug seen by various people. 2) I've updated to newlib-1.12.0 If you have problems updating your CVS tree, I've removed some previous outdated snapshots and older releases. You may have to tweak you CVS/Entries file to clean out some of the old ones. A quick way around the error would be to move you old tree out of the way an pull out a fresh tree. To access my tree you need to: Set CVSROOT in your environment to :pserver:anoncvs@baradas.org:/home/cvs Alternately add -d :pserver:anoncvs@baradas.org:/home/cvs in the CVS commands below (place it immediately after cvs, before any other arguments). Issue the command: cvs login You will be prompted for a password; reply with the string "anoncvs" (without the quotes). Issue the command: cvs -z 9 co xgcc to check out the compiler/binutils/newlib sources. Edit the Makefile to pick your flaver of the compiler and set PREFIX to where you want it installed. Execute 'make' to build/install the toolchain I've tested this code using Bernie's uclinux script to build a m68k-uclinux toolchain and built/ran a uClinux 2.4.x kernel on a 5407 board. If you have any problems accessing my server or building the code once you have it checked out, *please* contact me. I am *very* interested in feedback about how this update compiler works for you, both good and bad on any coldfire core. -- Peter Barada peter@the-baradas.com ------ Want more information?
