I have a customer who is complaining about slow SFTP transfers over a long haul connection. The current transfer rate is limited by the TCP window size and the RTT. I looked at HPN-SSH, but that won't work because we don't control what software the peer is using. I was thinking about coding a much more modest enhancement that just does SO_RCVBUF for specific subsystems. In the interest

That's true for block ciphers, but ChaCha20+poly1305 is a stream cipher.

Hi Guys, We are trying to come up with Bi-Endian(neutral endiness) compiler using the LLVM. For a introduction . http://www.drdobbs.com/architecture-and-design/writing-a-bi-endian-compiler/240003090 Did someone from the group ,aware of such project . Thank you ~Umesh

...;t come up with a reference for you, but I would take Chris' "I'm deeply unsure of what impact that would have on the security of the cipher" comment seriously and switch to a cipher with a 128 bit block length (AES or Camelia).

...zation below may not be profitable (see 14.3.3.6 and 15.3.1.2 in the Intel optimization reference manual). Having said that, one distinct possibility is to have the heuristic make different decisions depending on the optimization flags, that is be much more aggressive for optsize functions.

Hi, We are currently developing an LLVM target for a micro-controller, and would like our TargetLowering::LowerCall method to emit PUSH instructions (instead of STORE) to pass arguments (which would improve code density for function calls). Is there a way of keeping track of the stack pointer changes implied by the PUSH instruction to calculate the correct offsets in

Hello, I have another question as to what we need to use with our stations, if Icecast is what we need. We will be simulcasting three stations through DSL. No one will be accessing this but our stations. We will put out our programming from the main office, hook up a computer at three stations to receive the feed and put it out on air. Then also we will be on the internet with one of the

Hello all, In r223757 I've committed a patch that performs, for the 32-bit x86 calling convention, the transformation of MOV instructions that push function arguments onto the stack into actual PUSH instructions. For example, it will transform this: subl $16, %esp movl $4, 12(%esp) movl $3, 8(%esp) movl $2, 4(%esp) movl $1, (%esp) calll _func addl $16, %esp

I have been quietly working on a port of LLVM to Stratus VOS. The OS is always big endian (because customers need to migrate data to new hardware quickly and can't afford to convert). This entails presenting a big endian programming model no matter what the hardware does. We did this about 15 years ago with the Stratus compilers and GCC. We offered the GCC changes back to the
