| | | | | | | | | | | | | | | | | | | | | | Drastically quieten down the verbose load progress messages. They were more useful for debugging than anything, but are beyond a joke when loading a few dozen modules. Simplify the ELF extended symbol table load format. Just take the main symbol table and the string table that corresponds. This is what we will be getting local symbols from. (needed for the alpha stack tracebacks). Use the (optional) full symbol tables in lookups. This means we have to furhter distinguish between symbols that can come from the dynamic linking table and the complete table. The alpha boot code now needs to be adapted as ddb/db_elf.c cannot use the simpler format. I have not implemented loading the extended symbol tables from the syscall interface yet, just for preloaded modules. I am not sure about the symbol resolution. I *think* it's possible that a local symbol can be found in preference to a global, depending on the search sequence and dependency tree. Notes: svn path=/head/; revision=40254

* First shot at loading elf symbols. Things are a bit strange becausePeter Wemm1998-10-021-13/+126
| | | | | | | | | | | | | | | of the ..umm.. "wierd" way binutils lays out the file. The section headers are nearly at the end of the file and this is a problem when loading from a .gz file which can't seek backwards (or has a limited reverse seek, ~2K from memory). This is intended to be compatable with the ddb/db_elf.c code and the alpha/libalpha/elf_freebsd.c layout. I've studied these (which are NetBSD derived) but did it a bit differently. Naturally the process is similar since it's supposed to end up with the same result. Notes: svn path=/head/; revision=39887
* ELF loader, part 1. It works with ELF kernels generated on the i386Peter Wemm1998-09-301-0/+276
so far, and should probably be able to be made to work for the alpha without too much trouble once it's connected up and my assumptions tested. I think (but have not tested) it will also load "old" ELF kernels that were not linked with DYNAMIC headers. The module glue is yet to come. (oh fun.. :-) It does not explicitly load symbols [yet]. The _DYNAMIC data contains a runtime symbol set that ddb can use via ddb/db_kld.c. It'll be missing some detail that stabs normally provides (eg: number of args to a function, line numbers, etc). On the other hand, those minimal symbols will always be available even on a stripped kernel. This is mostly stolen from load_aout.c with some ideas from alpha/libalpha/elf_freebsd.c.
