...pbqp. I used it to undo some of the coalescer work, and make sure that I have different virtual registers, inserting a copy if necessary, to build a pair. I noticed an unexpected --- to me at least --- behaviour of the allocator. I have some instructions using 2 pairs of registers, say "mpra R_x, R_x+1, R_y, R_y+1", and setting the pairing constraints R_x -> R_x+1 and R_y -> R_y+1 could silently produce wrong code like "mpra %R0, %R2, %R1, %R3". I add to explicitly add another constraint to describe that y must differ from x, x-1 and x+1 to make the allocator build va...

...99% of the cases, but I am stumbling on the following issue. Instruction 'MPQD' takes 3 register operands inputs, with the constraint that operands 0 and 2 must be consecutive registers. Operand 1 has no particular constraint. It has no output register. So we have something like MPQD R_n, R_x, R_n+1. I have derived from PBQPBuilder to add the MPQD constraint. It happens sometimes that the code for register allocation looks like this : ... MPQD %vreg80, %vreg79, %vreg80; GR16:%vreg80,%vreg79 ... Operands 0 & 2 have been coalesced and I can no longer set the constraint. I tr...

Hi Arnaud, That sounds great. I look forward to seeing a patch. You may also look forward to big performance improvements in the PBQP allocator: I'm working on updates which will improve compile speeds and massively reduce memory use. Regards, Lang.

I also considered this approach, but did not want to dive in the constraint handling for now. The PBQP path seemed easier at first sight --- and was easy to setup. And I always wanted to give a try to the pbqp :) I will add the hook to the pbqp and propose a patch if this looks clean enough.

...ally, MS Word 2000 template files (Work Group Templates) are maintained in a shared Samba directory. File access is limited to the template administrator via UNIX permissions (755) - The template administrator is the owner of the files. The administrator has RWX permissions and all other users have R_X permissions. If a user is creating a document using a shared template, the template file is opened by Samba read-only and if the administrator attempts to edit the template, the file will only open read-only. If the user exits the template based file, the administrator can open the template file r...

Hi all. I am a pretty new user, but I now have two networked PC's, with LINUX (current Slackware distro, kernel 2.4.22?) with dual boot with WINXP (Prof), and a networked WINXP (Home) client machine. Here is my problem, stated as succinctly as possible: "To state it in one sentence, what must one do to enable a WIN(XP) client box to access WIN(XP) partitions on another machine that is

Thanks, I think that's a useful way to look at it (though if I wanted to bikeshed I'd suggest the name "DoubleIndirect" as a bit more precise than "VeryIndirect"). An aspect of it that I'm still puzzling over is that my target runtime (at least in its current form) doesn't have a way to represent/process a "VeryIndirect" pointer. So I'd like to

I'm running a few servers sitting on top of a NetAPP file server ? everything runs great, but periodically I'm getting: nfs_getpages: error 13 vm_fault: pager read error, pid 11355 (https) errors on my screen ? not always same pid ? the annoying part is that it seems to always affect the same jail that is running .. if I shutdown all jails on that physical server, everything shuts down
