Ah, my mistake. So this already works. I guess that bug is out of date, since this feature works already. -- John Harrison On Wed, Feb 6, 2013 at 10:00 AM, Joshua Cranmer <pidgeot18 at gmail.com> wrote: > On 2/6/2013 11:43 AM, John Harrison wrote: > >> The way `-ftest-coverage -fprofile-arcs` works at the moment it only >> flushes via `atexit()`.

Why does __gcov_flush only flush the current compilation unit? For gcc __gcov_flush flushes all of the loaded files. Is there a way to have __gcov_flush flush everything? -- John Harrison On Wed, Feb 6, 2013 at 10:24 AM, John Harrison <ash.gti at gmail.com> wrote: > Ah, my mistake. So this already works.

Thank you. The edit made no difference. I did a clean install and the same error is reported. Any other suggestions? regards, Ashwin On Aug 21, 2012, at 2:59 PM, Joshua Cranmer <pidgeot18 at gmail.com> wrote: > On 8/21/2012 3:52 PM, Ashwin kumar wrote: >> Hi everyone, >> >> This is Ashwin.

The way `-ftest-coverage -fprofile-arcs` works at the moment it only flushes via `atexit()`. This patch allows you to flush the coverage at any point by calling `__llvm_gcov_flush` the same way `__gcov_flush` works for gcc. If there is another way of doing this, I might of missed it but I was looking for `__gcov_flush` and I did not find the equivalent in llvm at the moment. -- John Harrison

Hi everyone, This is Ashwin. I have a mac running osx 10.8. I am new to LLVM and have the version 3.1 installed. I am trying to get some LLVM transform passes running on my machine. After having compiled the LLVM source without making changes to the configuration files I am able to run the LLVM gcc and clang. But I am having some trouble using the passes. I tried loading the hello pass inside the

Hi, I'm currently writing an opt module for fast indirect call checks using a table of allowed indirect call targets. The code replaces function pointers with offsets into the table then masks the offset for the table size and restores the function pointer before the call. I have some ways of dealing with some kinds of external code that are sufficient for my use case but not for more general

Thanks, you have a lot of valid points there. I have myself long ago abandoned the path of using C as a backend language due to the very factors you mention. However, as I said, the document was put together in 30 minutes. Not exactly ready for prime time :-) I do agree that all of the things you mention should be described, including Lambdas, closures, and generators, but I must admit up

Does anyone know of any loop strip-mining passes implemented in LLVM? -- Joshua Cranmer News submodule owner DXR coauthor

Yikes! It only flushes the counts for the current compilation unit? That sounds like a terrible bug. Can you file a bugzilla report, please?
