I misread the association on Shuxin's example, but even ((a*b) + (c*d)) + e would match to a 3-instructions: (fadd (fma a b (fmul c d)) e). If there are hairier examples that really require reassociation my vote would be for this last scheme: An FMA-friendly reassociation pass run before isel that exposes simple patterns for isel to match. - Lang. -------------- next part -------------- An HTML attachment was scrubbed...

...are anxious to tighten security. They hope to only allow tftp traffic on port 69, coming and going. This would bypass the RFC1350 client TID=ephemeral and server ACK TID=!69. Is there any chance tftpd-hpa would do this with "-R 69:69", or would this require tftpd-hpa to threaded, with a hairier connection lookup? Can the syslinux client be constrained to send tftp from port 69? [ googling, R'ing TFM, and even glancing briefly at the code don't provide quick clarity ...]

...es, will there be a problem with locking? Or will it be ok, since they both just use the underlying Unix locks? Has anyone done this? Regards, Matt PS. Another possibility that occurred to me is the have the second server on a second machine NFS mounting the first. But I think this would be even hairier. -- To unsubscribe from this list go to the following URL and read the instructions: http://lists.samba.org/mailman/listinfo/samba .

Or are we saying the same thing? (Your words of "fast isel spot"ting and "form better code" caused me to think you mean to do optimizations within the fast isel pass).

...he dark with this. Well that's really just a specific manifestation of implementing virtual function calls basically. The key to this issue is virtual function tables or vtables. Again you can explore this by looking at how LLVM compiles some appropriate C++ examples, though it's a little hairier. Try feeding the following example through llvmgcc -S struct base { virtual float foo() = 0; }; struct derived: base { float foo() { return 4.5; } }; float test(base* b) { return b->foo(); } float test_derived() { derived d; return test(&a...

Hi! i'm tring to figure out how classes and dependencies can be mapped to llvm. I've read on docs that nesting can be used: class base { int Y; }; class derived : base { short Z; }; becomes: %base = type { int } %derived = type { %base, short } That's ok, but now the question is: how do i encode a function that takes "base" type so that it also takes "derived"

Hi, Is it possible to add edges to the CFG from instructions that reference memory to exception landing pads? I want to do this so that I can convert SEGV signals into exceptions that can be safely unwound and caught. My compiler's existing code generator handles this by having a combined memory dereference and jump on null instruction. LLVM doesn't seem to have anything similar - I was

I''m wondering if ferret has any built-in search/replace mechanism that I might be able to use to highlight the query data in each search result. The reason I think this would be a good idea is that I could end up having to practically duplicate the ferret query parser just to interpret the query so that I can figure out how to highlight the keywords in the search results. Just in case

Hi, Using OpenSSH 2.9p2 (2.5.2 was also bad), I've noticed data loss on Linux when: 1) ssh -n flag is used, and 2) ssh jobs are run from cron (effectively causing the same as above). What is done, is a command basically like: ssh [-n] -c blowfish -p 722 -i rsakey -l pwget passwdserver passwd > passwd.tmp 2> /tmp/log ie, retrieve dynamically created passwd-file from passwdserver

Guys, I''m frankly overwhelmed by the number of Rails authentication options(?) out there...from ActiveRBAC to acts_as_authenticated to LoginEngine and so on...so many options, yet on resource I''ve found really distinguishes between each. This is sad, as authentication and user management is really an area where some Rails simplicity pixie dust could be a real boon to
