I am wondering how the following issue was handled for libLTO? We have a working patch to implement the FSF gcc LTO on darwin which now passes all of the liblto testsuite but are seeing linker issues with larger programs like aermod... as -arch x86_64 -force_cpusubtype_ALL -o aermod.o aermod.s /usr/bin/ld -dynamic -arch x86_64 -macosx_version_min 10.6.3 -weak_reference_mismatches non-weak -o aermod -lcrt1.10.5.o -L./ aermod.o -lgfortran -lgcc_s.10.5 -lgcc_ext.10.5 -no_compact_unwind -lSystem -v @(#)PROGRAM:ld...

Nick, Steven believes that aermod certainly could have more than 255 sections. Is there a particular approach that would be recommended for working around such a problem? Short of reducing the actual number of sections? It is suggested that this is why -ffunction-sections doesn't work on darwin and that one possible solution...

Compared to the previous results on 18 Sep 2010 for llvm 2.8, the regressions in ac are retained and aermod is now also regressed 13% as well as fatigue by 12%.

...rks 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 skews the geometric mean of the run time to much higher values.

I can confirm this is in fact fixed in current dragonegg svn. On a different question, what are the prospects getting aermod to compile under dragonegg? I am still seeing compile failures of the form... de-gfortran45 -ffast-math -funroll-loops -msse3 -O3 aermod.f90 -o aermod Assertion failed: ((NumParams == FTy->getNumParams() || (FTy->isVarArg() && NumParams > FTy->getNumParams())) && "...
