re PR fortran/47359 (Recursive functions of intrinsic names generates invalid assembler)
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.
