If there are no objections, then I can go ahead and commit the attached test case fix I mentioned before. Adding ALWAYS_INLINE to 'free_common' in r158885 changed

Hi, Indeed, the complex add is more expensive on all Cortex cores I know of. However there is an important point here that the code sequence we generate requires two registers live instead of one. In high regpressure loops, were probably losing performance. James On Wed, 11 Nov 2015 at 21:09, Tim Northover via llvm-dev < llvm-dev at lists.llvm.org> wrote: > On 11 November 2015 at

Hi Meador, Have you filed a bugzilla report? What's the PR number?

Hi Meador, I couldn't reproduce the ASan failures on my 10.8 machine (trying that on a 10.7 one now) I'll look into making the in-process symbolizer work on OSX (which should fix some of the ubsan failures), but we do not need it in production currently, so I'm not sure when I get to it.

Hello all, I don't find anything helping me understand the llvm bang operator. In the llvm TableGen language reference, it only says: 'TableGen also has “bang operators” which have a wide variety of meanings: *'* I would be very thankful if someone can explain it to me. e.g. what does "!strconcat" or "!if" mean? Cheers ES -------------- next part --------------

I also encounter this issue and solved it locally by implementing this 2 functions. - The linux version of StartSymbolizerSubprocess uses only POSIX function and can be reused as is on OS X (maybe we should move it in a new sanitizer_symbolizer_posix.cc file) - I have a simple implementation of GetListOfModules (see the attached file) but it required 10.6 at least. That said, implementing this

Hi, I was looking at some AArch64 benchmarks and noticed some simple cases where addresses are being folded into the address mode computations and was curious as to why. In particular, consider the following simple example: void f2(unsigned long *x, unsigned long c) { x[c] *= 2; } This generates: lsl x8, x1, #3 ldr x9, [x0, x8] lsl x9, x9, #1 str x9, [x0, x8] Given the two
