This patch introduces an optimized assembler version of md5_process(), the inner loop of MD5 checksumming. It affects the performance of all MD5 operations in rsync - including block matching and whole-file checksums. Performance gain is 5-10% depending on the specific CPU. Originally created by Marc Bevand and placed in the public domain, later...

Hello, I am using a dict proxy for my sieve extdata plugin to access some fields from an SQLite database (autoreply text and other database-configured items). All tests are performed against version 2.2.25. $ dovecot --version 2.2.25 (7be1766) My configuration looks like: dict { sieve = sqlite:/etc/dovecot/pigeonhole-sieve.dict } [...] sieve_extdata_dict_uri = proxy::sieve I am able to read pretty much any attribute without any issue, except when the value contains a spe...

Hi Evan, In -relocation-model=static mode, those tests are now getting code like this leaq A, %rsi movss %xmm0, (%rsi,%rdx,4) instead of this: movss %xmm0, A(,%rdx,4) This is specifically what these tests were written to catch :-). Running them with -relocation-model=pic is hiding the real bug. Dan On Feb 11, 2008, at 11:22 PM, Evan Cheng wrote: > Fixed. Thanks. >...

Hello, I have an optimisation issue in an llvm IR pass - the issue being that unnecessary instructions are generated in the final assembly (with -O3). I want to create the following assembly snippet: mov dl,BYTE PTR [rsi+rdi*1] add dl,0x1 adc dl,0x0 mov BYTE PTR [rsi+rdi*1],dl however what is created is (variant #1): mov dl,BYTE PTR [rsi+rdx*1] add dl,0x1 cmp dl,0x1 // <- not needed adc dl,0x0 mov BYTE PTR [rsi+rdi*1],dl in variant #2 the following is created: mov...

I am running into a problem with 'i1*' as a function's argument which seems to have appeared since I switched to LLVM 3.6 (but can have other source, of course). If I look at the assembler that the MCJIT generates for an x86-64 target I see that the array 'i1*' is taken as a sequence of 1 bit wide elements. (I guess that's correct). However, I used to call the function

...OverflowBit, 0), IRB.CreateZExt(IRB.CreateExtractValue(SumWithOverflowBit, 1), Int8Ty)); but that generated exactly the same as auto cf = IRB.CreateICmpULT(Incr, ConstantInt::get(Int8Ty, 1)); Incr = IRB.CreateAdd(Incr, cf); All the above create (with llvm 6.0, 7 and 8): mov dl,BYTE PTR [rsi+rdi*1] mov ecx,edx // <- not needed add cl,0x1 // <- should be done to dl instead adc dl,0x1 mov BYTE PTR [rsi+rdi*1],dl Thanks!

Andres: FWIW, codegen will do the merge if you turn on global alias analysis for it "-combiner-global-alias-analysis". That said, we should be able to do this merging earlier. -Nirav On Mon, Sep 10, 2018 at 8:33 PM, Andres Freund via llvm-dev < llvm-dev at lists.llvm.org> wrote: > Hi, > > On 2018-09-10 13:42:21 -0700, Andres Freund wrote: > > I have, in postres,

Hi ? I put the rsync in cronjob but it won't work ? in root user cron ? */30? * * * *? /home/chloe/rsy.sh >/dev/null 2>&1 ? 1/ why it needs pw when I run this rsy.sh in root? but if I run it in chloe user, it doesn't need pw as I put authoized_key in remote host chloe ? 2/ why this root cronjob is not working? what wrong? I can't see this cron in message ? the rsy.sh is

In the Zig frontend, we know at compile-time the entire call graph. This means we know stack size for all functions and therefore the upper bound stack usage. Recursive calls can have a runtime-decided stack usage, and therefore I am adding a frontend feature that will heap-allocate memory to use for some function calls. The idea is that recursion adds cycles to the call graph, and we know at compile-time for a given cycle which of the function calls enters the...

Hi, Chris (cc) and I try to get the SGE master monitor work with Apple Leopard dtrace. Unfortunately we are stuck with the error msg below. Anyone having an idea what could be the cause? What I can rule out as cause is function inlining for the reasons explained below. Background information on SGE master monitor implementation is under http://wiki.gridengine.info/wiki/index.php/Dtrace

Hello, I am experiencing problems, when trying to assemble these two x86-64 Opcodes "add r64, imm32" "imul r64, r64, imm32" When having the most significant bit set for imm32, for example: "add rax, 0x80000000", "add rax, 0xffffffff", ... "imul rbx, rsi, 0x80000000", "imul rbx, rsi, 0xffffffff", ... The Error Message I receive is the following: "Instruction:1:1: error: invalid operand for instruction" I was using the MCAsmParser, with the RelaxAll Flag set to true, for the MCStreamer. Can someone clarify, as to why this...
