For *iall*/*iany*/*iparity* it seems they non-s/m variant has been added recently, so maybe just an omission, for the *char4 symbols I have no idea. ^ permalink raw reply [flat|nested] 5+ messages in thread

They are called via gcc/fortran/iresolve.c. For instance: gfc_resolve_iall calls resolve_transformational ("iall", f, array, dim, mask); which in turn adds an "m" or a "s" as prefix if the intrinsic is called with a 's'calar or array 'm'ask -- without a mask, the pure "_i*" symbol is used. (And without "dim=" everything is handled in the front end.) A failing example is, e.g., INTEGER(1) :: a(2,2) logical :: mask(2,2) mask = reshape([.true.,.true.,.false.,.true.],[2,2]) PRINT *, IANY(a, dim=1,mask=mask) test.f90:(.text+0x1a6): undefined reference to `_gfortran_miany_i1' * * * Regarding _gfortran_cshift0_16_char4 and friends: Those are used for wide-char operations, where the shifts are given by large-sized integers; example: character(kind=4):: str(3,3) str(1,:) = [4_'A', 4_'b', 4_'C'] str(2,:) = [4_'A', 4_'b', 4_'C'] str(3,:) = [4_'A', 4_'b', 4_'C'] print *, cshift(str, shift=2_16, dim=1_16) end which fails with undefined reference to `_gfortran_cshift0_16_char4'. Ignoring issues like whether one should not cast the "2_16" to an integer(8) in the front end, which should be also sufficient giving 64bit address space, one should also export those symbols. ^ permalink raw reply [flat|nested] 5+ messages in thread
