Can you send it? Sure. See attached. This is the same as the patch provided by Ekaterina Sanina in the thread I linked. I can build fine with this applied for the

I am building LLVM on OS X 10.7.5 with cmake.

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

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

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?

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

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

Folks, I'm tracking down a buildbot failure on our self-hosting bot, and because there are several dozens of commits to track on a self-hosting issue (direct compilation goes well), I thought that showing the error on the list would be faster. src/include/llvm/CodeGen/SelectionDAGNodes.h:625: llvm::EVT llvm::SDNode::getValueType(unsigned int) const: Assertion `ResNo < NumValues &&

Hi Lang, LoadedObjectInfo::getSectionLoadAddress takes StringRef as an arg. That breaks if the object file has multiple sections with the same name. I made a change to add an overload that takes a SectionRef&. Can you please take a look? https://github.com/erozenfeld/llvm/commit/65f635e426bdc8e80a29ed370a78f0c0a282f265 Thanks, Eugene -------------- next part -------------- An HTML

There might be more than one code expert per area, which can be referenced by the code owner, but I wouldn't have more than one owner. Owning part of the code means you'll have to keep a sharper eye on
