* sim: drop duplicate header checksMike Frysinger2015-03-141-9/+8
| | | | | The SIM_AC_COMMON macro already checks for a bunch of headers, so specific sim ports need not do it themselves.
* sim: use AM_MAINTAINER_MODEMike Frysinger2013-06-051-0/+40
| | | | | | | I noticed the sim code is using an old implementation of the maintainer logic. I cut it over to the new macro (like gdb has been doing). In practice, it makes no difference currently as nothing in the sim tree uses it, but I have a follow up commit for the Blackfin tree that needs it.
* [PATCH] sim: make sure to include strsignal prototypeMike Frysinger2012-03-241-5/+6
| | | | | | | | | | | Before POSIX standardized strsignal(), old systems would hide the prototype unless the normal extension defines were enabled. So use the AC_USE_SYSTEM_EXTENSIONS helper for that. Then make sure we include string.h ourselves in nrun.c rather than relying on implicit includes via other sim headers.

* sim: generate build dependencies on the flyMike Frysinger2011-12-031-0/+89
Lift the code that GDB is using to generate dependencies on the fly and port it over to the sim. Now people shouldn't have to manually maintain these in their Makefile's. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
