...are that I' ve been successfully using on Windows XP before migrating to Linux Mint. It's Presonus Studio One, although that don't really matter right now. What matters is when I try to install it using Wine is says "Your computer can not run this software. The required feature set SSE2 is not supported.". Funny... Ok, so WineApp Database has no info on Presonus Studio One, but I don't mind that, because it's not the app that anyone would use. And ,well, the installer launches just fine untill it comes to that message. Does SSE2 have something to do with Wine or just...

...MS/FEMMS instructions to separate MMX and X87 states llvm.org/PR42320 <https://bugs.llvm.org/show_bug.cgi?id=42320> -- Implement MMX intrinsics with SSE equivalents *Proposal* We should re-implement all the currently-MMX intrinsics in Clang's *mmintrin.h headers by using the existing SSE/SSE2 compiler builtins, on both x86-32 and x86-64, and then *delete the MMX implementation of these intrinsics*. We would thus stop supporting the use of these intrinsics, without SSE2 also enabled. I've created a preliminary patch for these header changes, https://reviews.llvm.org/D86855. Sometime...

...r way to do this with GCC is g++ and target attributes. I've refactored the patch that way, and it indeed uses SSSE3 automatically on supporting CPUs, regardless of the build host, so this should be ideal both for home builders and distros. Getting the code to build right in c++ mode (checksum_sse2.cpp only) was a bit of an adventure, requiring modifications to mkproto.awk, configure.ac, and Makefile.in. I've done my best to prevent any c++ compilation happening in case the optimizations are not enabled (g++ isn't used, build target isn't x86-64, or --disable-sse2 was passed to c...

would it perhaps make sense to have a "--disable-sse2/3" commandline switch in rsync, too - at least for some timeframe until this is considered "rock solid" ? i dislike having automatic cpu feature switching code in a tool which needs to be reliable for me, this new optimization may have issues - and without such switch it can't b...

...;target-features"="+mmx" In the SelectionDAG phase in file "X86ISelLowering.cpp", i checked in one of the function what is the subtarget feature by calling few routines of Subtarget. Subtarget->hasMMX() ------ true Subtarget->hasSSE1() ------ true Subtarget->hasSSE2() ------ true These functions just compare the X86SSELevel with subtarget enum values like MMX, SSE1, SSE2 etc. hasMMX() { return X86SSELevel >= MMX}; // similar for others Now, enum values start from MMX and goes on increasing with SSE1, SSE2, etc. For the above test case, the X86SSELevel...

Hi all, Please consider committing the attached patch. I believe the SSE2 packsswb, packssdw and packuswb intrinsics have an incorrect return type.

...puters with the almost identical hardware (P4 Northwood CPU, i875 chipset, 2GB DDR400 RAM) and identical Linux OS. I have the latest version of libgoto for this CPU installed on both boxes (libgoto_northwood32p-r1.00.so) and I am using gcc compiler flags "-O2 -march=pentium4 -mfpmath=sse -msse2" to enable use of SSE2 extensions. With one computer that works perfectly, while on the other one "make check" constantly fails on lm-test. If I remove "-mfpmath=sse -msse2" part from the gcc flags then all checks pass on the second computer too. Any hints on what may c...

What do you base this on? Per https://gcc.gnu.org/onlinedocs/gcc/x86-Options.html : "For the x86-32 compiler, you must use -march=cpu-type, -msse or -msse2 switches to enable SSE extensions and make this option effective. For the x86-64 compiler, these extensions are enabled by default." That reads to me like we're fine for SSE2. As stated in my comments, SSSE3 support must be manually enabled at build time. Your comment would imply that SSS...

...ping that through a call to ParseAssemblyString, ExecutionEngine, etc. It's working OK on integer values, but i'm getting nasty floating point exceptions when i try this on double* values. I've seen this behaviour before on this platform (debian Intel P4) when I tried using ATLAS with sse2. I'm pretty sure it's valid assembly; the code still causes exceptions when i try using the output from the llvm demo website. And it works fine on an AMD machine. What is LLVM doing with my code ? Does it generate SSE2 instructions ? thanks! Simon. double sum_d(double*mem,int n) { do...

...S for this support, but is it really necessary? Maybe CPU check is enough? Operating systems that don't support SSE (Win95, WinNT 4.0, Linux kernel 2.2 (iirc), ...) are really outdated now. Removing OS check will greatly simplify src/libFLAC/cpu.c. 2. "configure" build system adds -msse2 option by default. It means that x86 (32-bit) library won't work on older, non-SSE2 processors. So if somebody wants to build a universal x86 binary then it's necessary to add --disable-sse (for Linux) or even --disable-asm-optimizations (for other OSes). Debian adds "--disable-asm-opt...

I'm not sure it's worth bothering. -Eli

When getting pqR to work on Windows, I've wanted for it to be able to use SSE2 instructions with 32-bit builds, for those 32-bit processors that have SS2 instructions (all of them from the Pentium 4 onwards). It seems that R Core 32-bit versions do not attempt this, instead using the 387 FPU for all floating-point arithmetic. This is sometimes slower than using SSE2 instruc...

Hi, I'd like to install the optimized libraries on my Thinkpad with an Intel Core Solo chip, which apparently supports the following instruction sets: MMX, SSE, SSE2, SSE3 instruction sets, XD-Bit. In a recent r-help message, the following was said (by Dirk I think): <quote> Yes, on Ubuntu, use 'apt-get install atlas3-base' for basic tuned Atlas, or 'apt-get install atlas3-sse2' assuming that sse2 is the closest fit to the cpu in questio...

Hi Simon, The x86 backend does generate scalar SSE2 instructions. For your example, it should emit something like: .text .align 4 .globl _sum_d _sum_d: subl $12, %esp movl 20(%esp), %eax movl 16(%esp), %ecx cmpl $0, %eax jne LBB_sum_d_2 # cond_true.preheader LBB_sum_d_1:...
