* trans-intrinsic.c (gfc_conv_intrinsic_minmaxloc): If the mask expression exists and has rank 0, enclose the generated loop in an "if (mask)". Put the default initialization into the else branch. 2006-02-28 Thomas Koenig <Thomas.Koenig@online.de> * scalar_mask_1.f90: Add tests for maxloc with scalar mask. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@111562 138bc75d-0d04-0410-961f-82ee72b054a4
