similar to: [LLVMdev] llvm-gfortran polyhedron 2005 results [corrected]

I've benchmarked the llvm 2.3/llvm-gcc-4.2 release against the stock gfortran compiler from gcc 4.2.4 on a 2.33GHz MacBook Pro using the '-ffast-math -funroll-loops -msse3 -O3' optimization flags. llvm-gfortran Benchmark Compile Executable Ave Run Number Estim Name (secs) (bytes) (secs) Repeats Err % --------- ------- ---------- ------- -------

Comparing the Polyhedron 2005 benchmark results for gfortran from llvm-gcc-4.2 of April 7th, 2010 and September 18th, 2010 (from the rc2 2.8 release branch), we seem to be regressing in performance for this release.... ================================================================================ Date & Time : 7 Apr 2010 22:24:16 Test Name : llvm_gfortran_lin_p4 Compile Command :

Very nice! A 14% speedup on a benchmark we don't tune for isn't bad. I imagine that there are several easy wins you could get on it if you were interested

Hi Jack, thanks for the numbers. Any chance of analysing why gcc does better on those where it does much better than dragonegg?

With the case-insensitive file system patch from http://llvm.org/bugs/show_bug.cgi?id=9656#c15 applied to dragonegg 2.9, the following Polyhedron 2005 benchmarks are seen on x86_64-apple-darwin10 under gcc 4.5.3svn using the dragonegg plugin... ================================================================================ Date & Time : 8 Apr 2011 19:52:56 Test Name :

It doesn't happen very often, but I can't imagine we would want to back that out. Fixing it would be a more reasonable solution. From a quick look at it, the problem is that gcc/config/darwin-c.c is registering va_opt

Building the current release 2.7 branch on x86_64-apple-darwin10 with r81455 reverted, I get the following Polyhedron 2005 benchmark results (with no test failures)... ================================================================================ Date & Time : 7 Apr 2010 22:24:16 Test Name : llvm_gfortran_lin_p4 Compile Command : llvm-gfortran -ffast-math -funroll-loops -msse3

Duncan, With r182593, the dragonegg 3.3 branch now completely passes the Polyhedron 2005 benchmarks using the FSF gcc 4.8.1svn compiler. Thanks.

[CCing Dale since this was his change, not mine] The change in 81455 fixes a compiler crash. It doesn't happen very often, but I can't imagine we would want to back that out. Fixing it would be a more reasonable solution. From a quick look at it, the problem is that gcc/config/darwin-c.c is registering va_opt for GC. When you build for Fortran, darwin-c.o is not linked so the GC gets

Below are the results for the Polyhedron 2005 benchmarks compiled with the llvm/compiler-rt/dragonegg 3.3 release and 3.4svn against FSF gcc 4.8.2. The *-stock-de runs omit the -fplugin-arg-dragonegg-enable-gcc-optzns flag and the *-de-optnz runs include it. There seems to be little improvement between llvm 3.3 and 3.4 in the stock case which relies entirely on llvm for vectorization. Duncan, has

Duncan, With the commit from http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20121203/158488.html, the Polyhedron 2005 benchmarks complete again on x86_64-apple-darwin12.

Below are the results for the Polyhedron 2005 benchmarks compiled with llvm/compiler-rt/dragonegg 3.3svn at r182439 against current FSF gcc 4.7.3svn and 4.8.1svn. The only major bug remaining in the dragonegg 3.3svn support for gcc 4.8.x is http://llvm.org/bugs/show_bug.cgi?id=15980 which results in unresolved symbols for _iround and _iroundf in the aermod and rnflow testcases. Note that this
