* Stop requiring that .strtab has long alignment.gkoehler2020-05-261-3/+2
| | | | | | | | When ddb loads symbols, the .strtab contains char strings and doesn't need long alignment. Our bootloader provides long alignment, but I started loading symbols on powerpc64 without our bootloader. ok mpi@ guenther@ kettenis@

* teach ddb(4) about CTF. currently it only loads the CTF and uses it on amd64jasper2016-09-161-16/+3
| | | | | | | | | | | | to lookup the number of function parameters. however having this basic facility allows us to expand it's usage. currently hidden behind the (disabled) DDBCTF kernel option as some of the required tools are not available in base yet. in addition to that one also needs recent bootblocks that load the .SUNW_ctf kernel section. discussed with mpi@ over many a cider and ale in cambridge feedback and ok guenther@ mpi@

* ddb: add support for DWARF line number decodingmatthew2014-10-091-7/+48
| | | | | | | | | | | | | | | | | | | | | | | | | 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

* First pass at removing clauses 3 and 4 from NetBSD licenses.ray2008-06-261-8/+1
| | | | | | | | | Not sure what's more surprising: how long it took for NetBSD to catch up to the rest of the BSDs (including UCB), or the amount of code that NetBSD has claimed for itself without attributing to the actual authors. OK deraadt@

* When searching for the symbol table and string table we were lookingart2003-06-011-1/+25
| | | | | | | | | | | for ".symtab" and ".strtab" in the section names. Instead of doing that, look for section type SHT_SYMTAB for the symbol table and follow the link in sh_link to find the corresponding string table. This is a more correct way of doing things and will work better when the toolchain doesn't generate ".symtab" and ".strtab" names and it will work when there are multiple symbol tables. noone objected to this diff for at least a week.
