Bug ID: 15980
Summary: _iround and _iroundf undefined for dragonegg under gcc
4.8.0
Product: dragonegg
Version: trunk
Hardware: Macintosh
OS: MacOS X
Status: NEW
Severity: normal
Priority: P
Component: New Bugs
Assignee: [email protected]

Classification: Unclassified
Dragonegg 3.3svn and trunk both produce undefined symbols for _iround and
_iroundf when compiling the Polyhedron 2005 benchmark aermod.f90 with...
% /sw/lib/gcc4.8/bin/gfortran -fplugin=/sw/lib/gcc4.8/lib/dragonegg.so -O1
aermod.f90 -o aermod
and an undefined symbol for _iroundf for the reflow.f90 benchmark compiled
with...
% /sw/lib/gcc4.8/bin/gfortran -fplugin=/sw/lib/gcc4.8/lib/dragonegg.so -O1
rnflow.f90 -o rnflow
against gcc 4.8.1svn with uncommitted second patch from
http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20130401/170127.html
applied to the dragonegg sources.
These undefined symbols don't occur when dragonegg 3.3svn or trunk is compiled
against gcc 4.7.4svn. The issue appears to be due to the change...
http://gcc.gnu.org/ml/gcc-patches/2012-03/msg01100.html
which enabled BUILT_IN_IROUND{F,,L} on the gfortran front end.
