similar to: Preferred CPU model not allowed by hypervisor

I am using a debian 9 guest, hosted on a ESXi platform with nested virtualisation enabled. On this debian 9 guest when I run libguesfs-test-tool, it fails with an error: "qemu-system-x86_64: /build/qemu-DqynNa/qemu-2.8+dfsg/target-i386/kvm.c:1805: kvm_put_msrs: Assertion `ret == cpu->kvm_msr_buf->nmsrs' failed." Instead when I use a wrapper script and hook it with the env

This sounds like llvm.org/pr13320.

Hi all. I'm looking for an advice on how to deal with inefficient code generation for Intel Nehalem/Westmere architecture on 64-bit platform for the attached test.cpp (LLVM IR is in test.cpp.ll). The inner loop has 11 iterations and eventually unrolled. Test.lea.s is the assembly code of the outer loop. It simply has 11 loads, 11 FP add, 11 FP mull, 1 FP store and lea+mov for index

The two address pass is only concerned about register pressure. It sounds like it should be taught about profitability. In cases where profitability can only be determined with something machinetracemetric then it probably should live it to more sophisticated pass like regalloc. In this case, we probably need a profitability target hook which knows about lea. We should also consider disabling

Johannes, I tried the last one and it gave me this: error: unknown target CPU 'XYZ' note: valid target CPU values are: nocona, core2, penryn, bonnell, atom, silvermont, slm, goldmont, goldmont-plus, tremont, nehalem, corei7, westmere, sandybridge, corei7-avx, ivybridge, core-avx-i, haswell, core-avx2, broadwell, skylake, skylake-avx512, skx, cascadelake,

It is my actual target architecture ________________________________ From: Doerfert, Johannes <jdoerfert at anl.gov> Sent: Saturday, March 23, 2019 1:30 PM To: J S Cc: via llvm-dev Subject: Re: [llvm-dev] Generating object files more efficiently I copied "-march=XYZ" from your original email, you have to replace it with your actual target architecture or simply drop it.

-march for clang and -march for llc do different things unfortunately. -march for clang at least on x86 is the same as -mcpu in llc. Which is an artifact of gcc compatibility. ~Craig On Sat, Mar 23, 2019 at 1:40 PM Doerfert, Johannes via llvm-dev < llvm-dev at lists.llvm.org> wrote: > Oh, my bad. > > > Idk why llc seems to know that architecture but clang does not. > >

Hello all and thank you for reading this message. I am new to RoR, and ruby too, but i am quite excited about it. I am developing a RoR project and with active record associations in the following manner # Tables (all tables have only one record) CREATE TABLE `webcars_development`.`cars` ( `id` int(11) NOT NULL auto_increment, `model_id` int(11) NOT NULL default ''0'',

I recently moved from Fedora 13 to Fedora 14 and consequently to dovecot 2.0.8. Since then, I have observed that messages are not being marked as read in all cases. The general behavior is: 1. Use my mail client to read all unseen messages. All mail folders show no messages unread. 2. Tell mail client to check for new mail. 3. Mail client now says that some folders have new mail (1 or more

Hi! File_column plugin saves uploaded files to "public/model/image/model_id/filename", if i understand it correctly. Does it mean that it creates new folder for every image? I have product (model) that has_many images (model). Is it possible to use (or modify) this plugin that it would save my images to different folder, so the id of the model_id part would be id of the product

I have a multitable database with an observer logging changes into a datachange table. The create method inserts the data into the data change table, updates my model, and then trys to load from the datachange table. When it does this it WHERE clause that is generated for me is looking for a column model_id which I dont have. I don''t want to even have a field because this table will be

Hey everyone... I''m just getting my feet wet with relational databases using RoR models. The software I''m putting together relies on car parts. Originally I had the database set up as follows create_table :parts do |t| t.column :year, :string t.column :make, :string t.column :model, :string . . . end However, I now realize it''s much better to do it using
