I think we still have to support some laggard compilers, but also,
Fortran compilation is dog slow. Just compiling the interfaces takes as
long as compiling all the C in PETSc (including Fortran stubs).

Or you could just use ISO_C_BINDING. Decent compilers should support it.

Huh? Or a test that uses enough arguments to not pass in registers if
you insist on creating a test failure. Alternatively, do what the
documentation says. If you doubt the documentation, we can check the
assembly.

Shouldn't be necessary, but why are we so concerned about making a test
case

So we need a 64bit arm with gcc8 - for this testcase failure?

On x86-64 Linux, the first six integer arguments are passed in registers
(rdi, rsi, rdx, rcx, r8, r9). Multiple smaller integers are not packed
into these registers, but they are accessed as 32-bit (edi, ...).

Well it should atleast bite for functions that have 2 char arguments. Perhaps
none of the tests are using these routines..

Is the length passed in registers and incorrectly using the lower half
of the register provides the int part?

hm - I have gfortran-8 on my laptop - but haven't seen any testsuite

We'll have to test for this (probably compiler version) and change the
PETSC_MIXED_LEN / PETSC_END_LEN to use size_t instead of int.
