After hacking devel/flang to install. Simple testing by trying to compile and compile and run programs from gfortran's testsuite I have found % cd gfortran.fortran-torture/compile implicit_1.f90 F90-S-0000-Internal compiler error. create_ref:IM_BASE op#2 not based sym 302 (implicit_1.f90: 22) F90-S-0000-Internal compiler error. size_of: attempt to size assumed size character 0 (implicit_1.f90: 31) 0 inform, 0 warnings, 2 severes, 0 fatal for foo % cd ../execute Wrong code generated for data_3.f90, dep_fails.f90, der_io.f90, entry_6.f90, forall_3.f90, forall_5.f90, forall_6.f90, forall_7.f90, getarg_1.f90, intrinsic_nearest.f90, intrinsic_pack.f90, intrinsic_sign.f90, where18.f90, where_7.f90, and where_8.f90 This might be a gfortran extension, but I suspect a bug in flang. entry_2.f90 F90-S-0045-Data type of entry point e4 disagrees with function f3 (entry_2.f90: 22) F90-S-0045-Data type of entry point e3 disagrees with function f3 (entry_2.f90: 21) 0 inform, 0 warnings, 2 severes, 0 fatal for f3 Code generation bugs entry_4.f90 /tmp/entry_4-b1e98a.ll:167:14: error: expected '=3D' after instruction id ret void %18, !dbg !35 entry_7.f90 /tmp/entry_7-7901bf.ll:83:52: error: pointers to void are invalid - use i8* instead %35 =3D bitcast i64* %__master_entry_rslt346 to void* entry_8.f90 /tmp/entry_8-25b70f.ll:87:14: error: expected '=3D' after instruction id ret void %24, !dbg !32 ^ forall_1.f90 F90-F-0000-Internal compiler error. make_same_idx: illegal forall 2=20 (forall_1.f90: 59) There isn't an internal procedure in this program. This is a=20 bogus error message. intrinsic_associated.f90 F90-W-0155-END statement for internal procedure should be END SUBROUTINE (intrinsic_associated.f90: 125) 0 inform, 1 warnings, 0 severes, 0 fatal for associated_2 Flang does not support the TRAILZ intrinsic intrinsic_trailz.f90 F90-S-0038-Symbol, trailz, has not been explicitly declared (intrinsic_trailz.f90 ) 0 inform, 0 warnings, 1 severes, 0 fatal for test_trailz BTW, FreeBSD's bugzilla is probably a poor place to have a discussion concerning potential problems with flang.
