Daniel, Thanks for your reply. The syntax problem was corrected. I've ran the gdb_mbuild.sh script and had no problems that are directly related to my patch. I had a compilation problem with the spu-elf, but that seems to be in cvs-HEAD as well. I also changed the return type of the software single step method for spu-elf and the local return values from the method ("return" to "return 1"), since they were still void. The wince.c file modification was droped due to its removal from the tree. > Could you post a patch which changes the type of the > software_single_step gdbarch method to return int, updates infrun.c, > and nothing else?

Attached follows the patch that only changes the infrun bits and also the return type of the software_single_step methods for various archs. > When you're editing a bunch of tdep files, please use the > gdb_mbuild.sh script to make sure they all still compile. Thanks for the hint on this. Regards, Luis
