2015-06-06 Thomas Koenig <tkoenig@netcologne.de> PR fortran/47359 * arith.c (eval_intrinsic_op): Set warn flag for gfc_type_convert_binary if -Wconversion or -Wconversion-extra are set. (wprecision_real_real): New function. (wprecision_int_real): New function. (gfc_int2int): If -fno-range-check and -Wconversion are specified and it is a narrowing conversion, warn. (gfc_int2real): If there is a change in value for the conversion, warn. (gfc_int2complex): Likewise. (gfc_real2int): If there is a fractional part to the real number, warn with -Wconversion, otherwise warn with -Wconversion-extra. (gfc_real2real): Emit warning if the constant was changed by conversion with either -Wconversion or -Wconversion-extra. With -Wconversion-extra, warn if no warning was issued earlier. (gfc_real2complex): Likewise. (gfc_complex2int): For -Wconversion or -Wconversion-extra, if there was an imaginary part, warn; otherwise, warn for change in value. Warn with -Wconversion-extra if no other warning was issued. (gfc_complex2real): For -Wconversion or -Wconversion-extra, if there was an imaginary part, warn; otherwise, warn for change in value. Warn with -Wconversion-extra if no other warning was issued. (gfc_complex2complex): For -Wconversion, warn if the value of either the real or the imaginary part was changed. Warn for -Wconversion-extra if no prior warning was issued. * expr.c (gfc_check_assign): Remove check for change in value. * primary.c (match_real_constant): For -Wconversion-extra, check against a number in which the last non-zero digit has been replaced with a zero. If the number compares equal, warn. * intrinsic.c (gfc_convert_type_warn): Do not warn about constant conversions. 2015-06-06 Thomas Koenig <tkoenig@netcologne.de> PR fortran/47359 * gfortran.dg/array_constructor_type_17.f03: Adjust error message. * gfortran.dg/warn_conversion.f90: Add warning for change in value for assignment. * gfortran.dg/warn_conversion_3.f90: Add warnings. * gfortran.dg/warn_conversion_5.f90: New test. * gfortran.dg/warn_conversion_6.f90: New test. * gfortran.dg/warn_conversion_7.f90: New test.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
