...pass's getReturnBlock function returns null (see UnifyFunctionExitNodes.h), I'm back to square one of not having a single exit block. I'm wondering what would cause a CFG not to have a return block. The comments in UnifyFunctionExitNodes.cpp say: "If there are no return stmts in the Function, a null pointer is returned." But this doesn't make sense; even an empty void function has a return block with a ret instruction inside it. Is there some other kind of source code pattern that would cause an absence of a return block? Thanks, Trevor

In various debug dumps (eg., Clang's -ast-dump), various objects (eg., Stmts and Decls in that -ast-dump) are identified by pointers. It's very reliable in the sense that no two objects would ever have the same pointer at the same time, but it's unpleasant that pointers change across runs. Having deterministic identifiers instead of pointers would aid debugging:...

I know a few ppl have those CAC Adit 600's with t400 I can't seem to get my second span up on the T400 connected to the second spand on the adit (A:2) A:1 seems ok Can someone post they zaptel.conf span defintions And maybe a "print config" from the adit 600 cli I think my issue is timing srcs the coding, framing. bld out are all matched thx -------------- next part

Dear Trevor, I'm too lazy to convert your .dot file into a graph file, but I'll make some comments anyway. :) First, LLVM does not guarantee that a function has a single exit block. Multiple basic blocks can have a return instruction as their terminator instruction. There is a pass (Unify Function Exit nodes i.e., -mergereturn <http://llvm.org/docs/Passes.html#mergereturn>)

We can see: 1) Simple heuristic of not instrumenting small single BB functions improves instrumentation performance as expected. 2) Using simple heuristic is still slower than late instrumentation with pre-inlining: the later is 15% faster. 3) Late instrumentation produces the smallest profile s...

Hi, I'm confused about the entry and exit blocks of an LLVM CFG. I understand that every CFG has one and only one entry block, and this is confirmed by the existence of the getEntryBlock function in the Function class. But what about exit (a.k.a. return) blocks? At first I assumed that LLVM CFGs have one and only one exit block, too, but the following code is a counter-example:

Previously if you were root, and you tried to change directory into a directory which was not owned by you and not readable (eg. 0700 bin:bin), it would fail. This doesn't fail on regular directories because when you are root the kernel just ignores permissions. Although libguestfs in general tries not to duplicate kernel code, in the case where we emulate the FUSE access(2) system call,

My compliments on the release of syslinux-5.0 and happy holidays to the entire Syslinux team.? I have a longer message in me.? Lots of curiousity about the direction of the project, but that will have to wait until I finish my first 5.0 project (*not* my first Syslinux project), which just happens to touch past problems: drive enumeration. This particular effort is on a USB flash drive, with two

Greetings: I did some quick searching of my history of this list, and I tried a quick Google search as well, but perhaps someone on the list can quickly answer this question. I have a very nicely working Asterisk system at home with two Digium X100P FXO cards. When my SIP phones want to dial-out I have them setup to grab the first analog card (Zap/1) with the following extensions.conf segment:
