[CFT/RFC] Make crunched compatible with external linkers
Hello hackers, The following PR patches crunchide(1) to accept object files produced by the gold and mclinker linkers: http://www.freebsd.org/cgi/query-pr.cgi?pr=bin%2F174011 On behalf of the submitter, I'd like to request a review of the patch, and testing of crunchide/crunchgen especially on SPARC and ARM.

Re: libc with debugging symbols?
On Dec 4, 2012, at 1:24 AM, Myles C. Maxfield wrote: Hello, all, I'm interested in learning about the internals of how libc works, so I was hoping to link a test application with a version of libc that has debugging symbols (reading the raw sources only gets me so far). The version of libc that comes with FreeBSD doesn't have debugging symbols (nor should it), so I'm wondering if there is a way to install / compile my own. I have very naïvely checked out libc from /base/head at svn.freebsd.org, crossed my fingers, and ran 'make', but that didn't work (for many reasons, I'm sure). This leads me to the following questions: 1. Is it possible to check out the sources of libc (and possibly other libraries) as they were when the FreeBSD 9.0 release was being compiled (since that's what I'm running)? Is there a way to map this to a particular SVN revision? Yes. The handbook should cover the different possibilities, but you'll want to check out the code from http://svn.freebsd.org/base/releng/9.0 2. Is there a listing of the tools and versions used to compile libc at that time? It's all in what you checked out using the above link. 3. Many other unix-like distributions have something like a libc-dbg package in their package manager. Do you think this would be worthwhile or even acceptable for me to try to create something similar in the ports database? (I couldn't find anything that already exists) That's an interesting idea. However, it is easy enough to build what you need: cd svn-root-location# change this to the real path cd lib/libc make DEBUG_FLAGS=-g obj all install clean should suffice. It will add a bunch of space to your root and /usr partitions, iirc, but disks these days are so huge you won't notice. If you do, you can install to a different location using DESTDIR. Due to some interaction between different parts of the system that's a smidge more complex: cd svn-root-location make redistribute cd lib/libc make DEBUG_FLAGS=-g obj all install clean DESTDIR=/some/other/path If you are hacking on libc, you can omit the 'clean' step. If you are rebuilding libc, you can omit the 'obj' after the first time. If you are hacking on amd64, you may want to add WITHOUT_LIB32=t to the command line to disable the 32-bit build. To rebuild libc takes just a couple of minutes. Hope this helps.

I applied this patch to a 9/stable source tree, and was able to buildworld with it in place, on my sparc64 machine. I know that's not a great test case, but the patched binary is good enough to generate the objects that are needed for the 'rescue' binary. And that binary runs at least a trivial test of '/usr/obj/usr/src/rescue/rescue/rescue ifconfig -a' and produces correct output. -Kurt ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to freebsd-hackers-unsubscr...@freebsd.org

I see the same behaviour as Andre: the depend and all targets both iterate through the module directories sequentially. It never builds two module subdirectories concurrently. ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to freebsd-hackers-unsubscr...@freebsd.org
naming a .h file for kernel use only
Hi, For my NFSv4.1 client work, I've taken a few definitions out of a kernel rpc .c file and put them in a .h file so that they can be included in other sys/rpc .c files. I've currently named the file _krpc.h. I thought I'd check if this is a reasonable name before doing the big commit of the NFSv4.1 stuff to head. (I have a vague notion that a leading _ would indicate not for public use, but I am not sure?) Thanks in advance for naming suggestions for this file, rick ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to freebsd-hackers-unsubscr...@freebsd.org

Thanks in advance for naming suggestions for this file, rick I believe that _thing.h is the convention for the headers that are never directly included by the .c files. It is there to hide some shared parts of other includes, for consumption by includes. Why not move the stuff to sys/nfs/krpc.h ?
