I'm writing a back-end for an architecture that supports multi-word loads. As a concrete example, "ldqw r0, [addr]" would load a quadword (4 words) into 4 registers starting with r0 (implicit writes to r1, r2, and r3). First, is there any currently supported architecture that has anything like this? I suspect not. If not, I hope someone might help me figure out how to make this

It currently works by creating such instructions in a

Some additional fields from the EDD-4 spec. draft for the Device Parameter Table have been added into the structure in setup.c and memdisk.inc. These were added in the hopes of resolving a FreeDOS MEMDISK bug on IBM ThinkPads. --- memdisk/memdisk.inc | 11 +++++++++++ memdisk/setup.c | 10 ++++++++++ 2 files changed, 21 insertions(+), 0 deletions(-) diff --git a/memdisk/memdisk.inc

I've had this a long time but haven't submitted it yet. I've tried to mirror the ia32 setup, so there should be a new subdirectory src/libFLAC/ppc . The first two attachments go there. The third is a context diff for src/libFLAC/Makefile.am . I have some more modified files, which I figured I'd submit after the above are checked in and working for somebody other than me. If you

Hi Chandler, I have tested the new shuffle lowering on a AMD Jaguar cpu (which is AVX but not AVX2). On this particular target, there is a delay when output data from an execution unit is used as input to another execution unit of a different cluster. For example, There are 6 executions units which are divided into 3 execution clusters of Float(FPM,FPA), Vector Integer (MMXA,MMXB,IMM), and Store

Hi John & Ron, I read through the proposal and had a couple of quick observations. 1. The proposed encoding assumes that the epilogue instructions always come at the end of the function -- or rather, just before the next function. If there is a stack protector __stack_chk_fail sequence, or there is NOP padding between functions, then the epilogue cannot be expressed. The proposed encoding

Hello there, This series exposes NVIDIA's global performance counters for Tesla through the Gallium's HUD and the GL_AMD_performance_monitor extension. This adds support for 24 hardware events which have been reverse engineered with PerfKit (Windows) and CUPTI (Linux). These hardware events will allow developers to profile OpenGL applications. To reduce latency and to improve accuracy,

John and Ron, I developed the original compact unwind implementation for macOS 10.6 back in 2009. I tried to leave space in the design to support finer grain exception handling such as for asynchronous or for the shrink wrap optimization. The idea I had at the time was instead of having just one 32-bit compact unwind info per function, there could be an array of them each covering a different

Hello, I am currently trying to set up pjsip realtime and would like to have outbound-publish, inbound-publication, and asterisk-publication sorcery object types in ODBC realtime. Is that currently supported? I know that some object types are known working and others are not. I was curious what the status of those objects are. Thanks!

Hi Nick, It is a pleasure to be in contact with the creator of the compact unwind approach! I can see how an array of 32-bit unwind blocks could be used to describe each distinct point within a function (within a prolog in particular). But then you end up with six or seven or more such blocks for a large percentage of functions, don't you? Seems like a lot of additional space for something

Here is our proposal to extend/enhance the x86-64 compact unwind descriptors to fully describe the prologue/epilogue for asynchronous unwinding.  I believe there are missing/lacking CFI directives as well, but I'll save that for another thread.

Excellent. I was using ast-13.1.0 with no luck. I upgraded to 13.2.0 and have made it further, but am having a little difficulty. The outbound-publish object types seems to be working in realtime now. But the asterisk-publication object is only reading from sorcery.conf. I know you said that it *should* work, with no guarantee, which I'm fine with. I just want to make sure I don't

Here's what I listed in that email. Merging doesn't appear to be necessary. If you have any build problems, let me know. Note that my detection code is Darwin-specific. It's a BSD call (sysctl()), so a change to the platform-detection macros should enable it to work on other BSDs. However, I don't know what that would be, and I couldn't determine any safe way to do the check

I *think* I have found and fixed the Thinkpad MEMDISK problem. The problem with MS-DOS I understand... not so when it comes to an apparently unrelated FreeDOS problem, and as such I really don't know *why* the hack I did works, nor if it will *stay* fixed, but at least it seems to boot on my T61 (at least until it crashes due to another error...) -hpa -- H.

I'm currently running a pre 1.0 version of dovecot. Months back I tried to compile beta6, couldn't due to some mysql client libraries issues, and gave up. I'm now trying again with rc6. This is on a fedora core2 box, with postfix 2.3 and mysql 5.0. The error I'm getting when I run make is below. Any help would be greatly appreciated, thanks! I'd really like to get up to

Dear List members I am new to dovecot and am looking for a solution. I have googled as much as I could, but most likely my search criteria was wrong, and hence asking here. I am familiar with maildir format, and could easily do cat / grep / sed on those files to extract data. The server I am looking at now uses dbox format, which seems to store data in a different way. just to give you an

Sorry if this is a repost- I wasn''t sure if the www.ruby-forum.com list works for postings. I''ve been having trouble with indexing a large amount of documents(2.4M). Essentially, I have one process that is following the tutorial dumping documents to an index stored on the file system. If I open the index with another process, and run the size() method it is stuck at a number
