* unifdef __APCS_26__ we don't run on anything with a 26 bit program counter.jsg2014-12-305-61/+5
| | | | | This codepath was removed in the NetBSD code this is derived from back in 2003 and was removed in Bitrig earlier this year. No binary change.

* ddb: add support for DWARF line number decodingmatthew2014-10-091-4/+24
| | | | | | | | | | | | | | | | | | | | | | | | | This allows ddb's "trace" command to include file and line numbers: ddb{0}> trace Debugger() at Debugger+0x9 [../../../../arch/amd64/amd64/db_interface.c:405] ddb_sysctl() at ddb_sysctl+0x1b4 [../../../../ddb/db_usrreq.c:104] sys___sysctl() at sys___sysctl+0x216 [../../../../kern/kern_sysctl.c:229] syscall() at syscall+0x297 [../../../../sys/syscall_mi.h:84] --- syscall (number 202) --- end of kernel end trace frame: 0x7f7ffffcf1d7, count: -4 acpi_pdirpa+0x4117aa: For this to work, it requires using a new version of boot(8), and booting a kernel with the .debug_line section present (e.g., building with ``makeoptions DEBUG="-g"'' and then booting the bsd.gdb kernel instead of the stripped bsd kernel). Still a WIP, but no failure reports yet. Committing so further development and testing can happen in tree. prodding deraadt, guenther, mlarkin ok mpi

* KASSERTMSG(9): New kernel assertion with messageuebayasi2014-07-131-1/+17
| | | | | | | | | | | | | | | | | | | | | | | KASSERT() is annoying as it only prints the expression as a string. If you (developers) want to know a little more information, you have to do: #ifdef DIAGNOSTIC if (bad) panic(...); #endif KASSERTMSG() replaces it into a single line: KASSERTMSG(!bad, ...); Taken from NetBSD. (There is a concern that KASSERT() messages are too long; consume more memory, and not friendly for small monitors. This have to be considered & revisited later.)

* Protect explicit_bzero() from link-time optimizationmatthew2014-06-211-7/+12
| | | | | | | | | | | | | | | | | | | | Modern compiler toolchains are capable of optimizing even across translation unit boundaries, so simply moving the memory clearing into a separate function is not guaranteed to clear memory. To avoid this, we take advantage of ELF weak symbol semantics, and insert a call to an empty, weakly named function. The semantics of calling this function aren't determinable until load time, so the compiler and linker need to keep the memset() call. There are still ways a toolchain might defeat this trick (e.g., optimistically expecting the weak symbol to not be overloaded, and only calling memset() if it is; promoting weak symbols to strong symbols at link-time when emitting a static binary because they won't be interposed; implementing load-time optimizations). But at least for the foreseeable future, these seem unlikely. ok deraadt
