similar to: [LLVMdev] Position-independent stacks

Thanks Mark! That'd be a useful starting point. For the rest of the people here: to be a bit more specific, I am having doubts about the following: - Can later optimization passes or code generation still create machine code that takes and stores (in a register perhaps) an address of something on the stack, even if not semantically visible to the programmer? Can this somehow be detected?

Greetings, Sorry for the basic question, but I am trying to find out if R is a suitable platform for what I want to do... I am interested in creating simulations of distributed algorithms (i.e. team formation, Byzantine Generals , P2P communication modeling, mobile networks) that would be represented in GUIs. I would like to be able to instantiate an object for each node in my simulated

> Actually.. I seem to have jumped to improper conclusion.. One thing you will find abour spandsp is that some fax machines will just plain have a problem sending to spandsp, period. Mr. Underwood has localized it to cetain HP fax machines and I can confirm that HP all-in-one SOHO machines exhibit this problem, but I have also noted it with Canons and Panasonics. In my context, I have several

When LLVM's configure finds a usable <pthread.h>, it prefers to use that rather than the home-grown stuff. However if LLVM is configured with --disable-pthreads, both mingw flavors produce the same results. BTW, I've tried to quantify the slowdown: a quick test indicates that LLVM build that uses pthreads is about 10% slower than the one which doesn't. This is less that I

Hi, Is it somehow possible to have LLVM emit machine code for the 'unreachable' IR instruction, which would assert that it indeed never gets reached?

I am not seeing this happening, at least not for unreachables that follow calls to 'noreturn' functions.

Moat of the advanced persistent threats (APT) are initiated via e-mail. Opening an attachment or clicking on a web link starts the process. Why isn't Firefox and Evolution confined with SELinux policy in a way that APT can't damage the rest of the system? Why are we not sandboxing these two apps with SELinux? I've discovered some guidance for sandboxing Firefox using the

Hi, I received a small flurry of buildbot emails yesterday. Most of them seem to be repeats of previous failures and buildbot only mailed them to me because the previous build raised an exception instead of failing. However I noticed a couple configuration/system issues amongst them: * arxan_raphael is consistently hitting the 20 minute no-output timeout when running the link command

Hi All, For various obscure reasons I'd like to detect the condition when X86 CALL instruction immediately precedes a function epilogue in the final emitted code, and insert a NOP between them if that happens. My initial attempt at it looked like this: MachineBasicBlock& MBB; MachineBasicBlock::iterator MBBI; <-- points to where the epilogue would be inserted if (MBBI != MBB.begin()

Hi! LLVM has a class, ConstantExpr, that is very handy for compile-time evaluation of const expressions. Unfortunately I cannot find any methods in it that would be helpful in evaluation of expressions similar to this: (uintptr_t)(&(*(TYPE*)0).FIELD), which is basically the implementation of the offsetof(TYPE, FIELD) macro. Specifically, there seem to be no provisions for dereferencing a

Hi, I have a couple of questions about MachineBasicBlocks: - If I have a pointer to an MBB, is there an easy way to find which block that precedes it in the MachineFunction blocks list? (without iterating through all of the MF's basic blocks) - Does LLVM make any effort to ensure that MBB's predecessors and successors lists are semantically correct? For example, what happens if an MBB

I would like to be able to manage different db connections per request. I''ve gotten this working by using establish_connection in a before_filter on all controllers. My concern is whether or not there could be a race condition where two or more overlapping requests might reset the SQL connection. Is there any serialization logic which will prevent this? Must I introduce this logic
