Hi, In our department's setup we have a unfortunate situation where we have to use both OpenSSH and SSH (ssh.com's version). I have managed to export keys from OpenSSH to SSH's format. I also managed to export SSH's public key to OpenSSH's format. Now I would like to add the private key of SSH to the agent. Now when I try to add it simply by using ssh-add

Hi, I recently ran into a case, where x86 fails to run correctly. Checking into the emitted code, it seems that the local memory anchored at ebp has conflict with stack memory anchored at esp prepared for function calls. For example, let us say: foo() { ... call bar(); } There is some local data for foo() at ebp-170h. while preparing the call to bar, some data is written to esp+17h. The

Hello, I have a problem to install EBP BUSINESS PLAN with wine 1.1.42. Please help me. Ryadh

hi llvmdev list im currently investigating a missing optimizer feature in VS2010 - and comparing the VS2010 results with the result of clang 3.1 i've downloaded clang from http://llvm.org/releases/download.html -> Experimental Clang Binaries for Mingw32/x86 clang --version clang version 3.1 (branches/release_31) Target: i686-pc-mingw32 Thread model: posix ----- test.c typedef

Hi all, I'm implementing a virtual processor which features dynamic register indexing, and I'm struggling to make LLVM 3.0 produce good code for it. The register set is implemented as an LLVM array so it can be dynamically indexed using GEP. However, most of the time the virtual processor's registers are just statically indexed, and so I expected/hoped the code would be as

I submitted the problem report to clang's bugzilla but no one seems to care so I have to send it to the mailing list. clang 3.7 svn (trunk 229055 as the time I was to report this problem) generates slower code than 3.5 (Apple LLVM version 6.0 (clang-600.0.56) (based on LLVM 3.5svn)) for the following code. It is a "8 queens puzzle" solver written as an educational example. As

The regressions in the performance of generated code, introduced by the llvm 3.6 release, don't seem to be limited to this 8 queens puzzle" solver test case. See... http://www.phoronix.com/scan.php?page=article&item=llvm-clang-3.5-3.6-rc1&num=1 where a bit hit in the performance of the Sparse Matrix Multiply test of the SciMark v2.0 benchmark was observed as well as others.

Using the SciMark 2.0 code from http://math.nist.gov/scimark2/scimark2_1c.zip compiled with the same... make CFLAGS="-O3 -march=native" I am able to reproduce the 22% performance regression in the run time of the Sparse matmult benchmark. For 10 runs of the scimark2 benechmark, I get 998.439+/-0.4828 with the release llvm clang 3.5.1 compiler and 1217.363+/-1.1004 for the current

Compile the following functions with "-O3 -target i386" (see <https://godbolt.org/z/VmKlXL>): long long div(long long foo, long long bar) { return foo / bar; } On the left the generated code; on the right the expected, properly optimised code: div: # @div push ebp | mov ebp, esp | push dword ptr [ebp + 20] | push

Hello guys, Thanks for your help when you are busing. I am working on an open source project. It supports shader language and I want JIT feature, so LLVM is used. But now I find the ABI & Calling Convention did not co-work with MSVC. For example, following code I have: struct float4 { float x, y, z, w; }; struct float4x4 { float4 x, y, z, w; }; float4 fetch_vs( float4x4* mat

Hi all not sure if this is the right list to ask a question I am using icecast 2 with station playlist creator And I have in my Schedule 3 shows set one at 18.00 1 at 19.00 and 1 at 20.00 The 18.80 started bang on time but the 19.00 started on time but when it got to 20.00 the 19.00 show started again How I have set it up is just adding the shows in creator Mark. Tune in to the number one

I tend to agree, but the constructors won't get called if it's an object array -- anyway, this particular case there was no objects, just pointers and bools so alloca should be fine. I'll leave it to

I'm trying to get Wine to print through it's PS driver, without success, on a HP DeskJet 694C, configured on Linux with the cdj670 driver. What I get to see on screen after I attempt to print are three windows with exclamation marks on a yellow triangle and garbled text. The first window is titled "Printer name", the second "Device name", the third "Output".

Hi @ll, targetting i386, LLVM/clang generates wrong code for the following functions: unsigned long __bswapsi2 (unsigned long ul) { return (((ul) & 0xff000000ul) >> 3 * 8) | (((ul) & 0x00ff0000ul) >> 8) | (((ul) & 0x0000ff00ul) << 8) | (((ul) & 0x000000fful) << 3 * 8); } unsigned long long __bswapdi2(unsigned long

Hi all. I am working on constructors implementation for MS ABI. Itanium ABI has 2 constructor types - base & complete. MS ABI has only 1 type. How it works I'll show on example. class first { public: virtual void g(){} }; class second : public virtual first { public : virtual void g(){} }; When construct instance of second we will have next code push 1 lea ecx,[f]
