Hi,
Thanks for your explanation! I closed the issue. https://linaro.atlassian.net/browse/LLVM-1398
Takahiro Kawashima, Fujitsu
Hi there!
These are legitimate regressions: the code compiled to bogus BIND(C) ABI that only worked when using with Fortran to Fortran. A TODO is now correctly emitted until the proper ABI is implemented.
In Fujitsu-Fortran-0379_0074
function strfunc() bind(C) type,bind(C) :: str integer :: iii end type type(str) :: strfunc end function end interface type,bind(C) :: str integer :: iii end typePreviously, the result was passed in as a hidden extra argument, like it is done in normal Fortran ABI. On ARM, the equivalent C code is returned in registered as far as I can see: https://godbolt.org/z/nec6jbhYM
0384_0028.f90 also has BIND(C) function returning such BIND(C) types.
So, both tests should not be run on ARM, or should expect a TODO error message until the feature is implemented on ARM.
