On ubuntu hardy on x86-64, using current svn, llvm builds fine, but I'm getting this when building llvm-gcc: /usr/bin/ld: i386:x86-64 architecture of input file `/usr/lib/../lib/crti.o' is incompatible with i386 output /usr/bin/ld: i386:x86-64 architecture of input file `/usr/lib/../lib/crtn.o' is incompatible with i386 output Searching the web for these messages turned up a few

After dropping clang into llvm/tools it builds fine but I get the error below upon "make install". This is on Ubuntu Hardy for ia32. No big deal just giving a heads up...

I'm away from my Linux machines, if this hasn't been resolved by tonight I'll send more details. THe problem in cplus-dem.c is that CPP is conditionally including code that comes when HAVE_STDLIB is not defined, including an alternate protptype for malloc() that conflicts with the existing one. This is just what causes the error I sent-- no idea what the root cause is. Thanks,

As you all have undoubtedly noticed, I recently did Yet Another Merge to Apple's GCC top-of-tree. This merge was prompted by several important fixes in the "blocks" implementation. There are still many testcases that need to be moved over, but those can come at our leisure. I compiled both the "Apple way" and the "FSF way". It also passed the tests in

Since yesterday I've been getting the error below when building llvm-gcc on Ubuntu Hardy on x86. For some reason, several instances of autoconf are getting confused and failing to detect a stdlib.h.

One thing that is important to consider is where in the pipeline these kinds of optimizations fit. We normally try to put the IR into a canonical simplified form in the mid-level optimizer. This form is supposed to be whatever is most useful for exposing other optimizations, and for lowering, but only in a generic sense. We do have some optimizations near the end of our pipeline (vectorization,

My InlineCost refactoring has been noticed in this aspect; that may or may notbe the culprit here. A quick thing you can do is to compile with -ftime-report and compare the top few passes between versions.

Cool! Looks like we do lots of provably unnecessary alignment checks. :) On Tue, Nov 25, 2014 at 9:03 AM, John Regehr <regehr at cs.utah.edu> wrote: > Actually, let me save you some time by pointing out the thing that is > perhaps immediately useful about our recent work, which is the fact that > Souper now supports "optimization profiling". > > If you build an

Hi, I'd like to see what parts of LLVM/Clang are being executed. I know that "make ENABLE_COVERAGE=1" used to just work, but so far (on 64-bit Ubuntu 14.04) I've had no luck building either 3.4.x or SVN head using any of Clang 3.4, Clang head, or a recent GCC. The first error that I get when building with GCC is this:

I strongly suspect pointer union and pointer int pair style classes are the source of these...
