Sorry. Should have been more explicit:

9 years ago Hm, I just don't see it here. With r245248 from the release_37 branch (which corresponds more or less with rc2/rc3):

Even the -fopenmp flag does not matter.
How exactly are you building your clang executables? Manually, or via ports?

9 years ago It works for me on FreeBSD 11; with trunk r242221:
$ /usr/bin/time -l clang++ -O2 -std=c++11 -I. -c PulseTable.cc 71.35 real 70.03 user 1.69 sys 897312 maximum resident set size 43525 average shared memory size 210 average unshared data size 127 average unshared stack size 361213 page reclaims 0 page faults 0 swaps 0 block input operations 3 block output operations 0 messages sent 0 messages received 0 signals received 7 voluntary context switches 1086 involuntary context switches
With trunk r245199 it does take a lot longer, though:

I haven't tried compiling on FreeBSD 11. I have FreBSD 11 r286926 in a virtual instance however clang++ on r286926 identifies itself as:
root@Head:~ # clang++ -fopenmp -v foo.cc FreeBSD clang version 3.6.1 (tags/RELEASE_361/final 237755) 20150525
In a follow-on Bugzilla note I wrote 3.6 works however my problem is 3.8 where I /require/ OpenMP (I also require FORTRAN (numpy) but GCC/clang seems to have issues with the many libraries GNURadio requires).
I haven't tried 3.7rc2 because I was looking for devel/clang and not devel/llvm, which is compiling now. :)

9 years ago It looks like SROA is really slow on this.

9 years ago I can confirm this file DOES compile under 3.4.1/FreeBSD (see "3.4.1" below). It takes roughly 8 minutes. The prior 3.8.0 case is still working after 123 minutes but appears appears to be related to optimization (see "3.8.0" below). Specifically, without -O the file compiles quickly under 3.8.0.
I have also run 3.5.2 and 3.6.2 but on a different host (Junker). Both optimization and no optimization compile (see "3.5.2" and "3.6.2" below for optimization cases).

Extended Description
I have a file that doesn't seem to complete compilation under clang++/FreeBSD-10.2 -- certainly doesn't compiler against 3.8 but I've had trouble with earlier versions. The file does compile under g++ 4.8, 4.9, and 5.2 in the same environment. After twelve minutes, I ctl-C.
The compiler line:
The compiler identifies itself as:
