--- Comment #9 from kargl at gcc dot gnu.org --- I have updated the diff. I don't know have ChangeLog works under git. Here's what I have written. * gcc/fortran/gfortran.texi: Remove the "Extended math intrinsics" node. It documented the only the degree trigonometric functions. That is, it was a very limited list of the additional nonstandard intrinsic subprograms offered by gfortran. Most of these functions are now part of Fortran 2023. * gcc/fortran/intrinsic.cc(add_functions): Degree trigonometric functions [A]COSD, [A]SIND, [A]TAND, and [A]TAN2D have been added to the Fortran 2023 standard. These were originally added for compaitiblity with DEC Fortran under the -fdec-math. Change these from GFC_STD_GNU to GFC_STD_F2023. (gfc_check_intrinsic_standard): Add a check for Fortran 2023. * gcc/fortran/intrinsic.texi: Update documentation for [A]COSD, [A]SIND, [A]TAND, and [A]TAN2D.
