--- Comment #6 from Thomas Schwinge <tschwinge at gcc dot gnu.org> ---
As nvptx target is known to be sensitive to such mismatches (outside of the LTO
context reported here), I individually did test this commit
r13-5100-g0986c351aa8a9f08b3cb614baec13564dd62c114 "fortran: Fix up function
types for realloc and sincos{,f,l} builtins [PR108349]", and found that it also
resolves the following nvptx target compilation failures:
'gfortran.dg/pr35662.f90':
ptxas /tmp/ccYNgEEN.o, line 44; error : Illegal operand type to
instruction 'st'
ptxas /tmp/ccYNgEEN.o, line 51; error : Type of argument does not match
formal parameter '%in_ar0'
ptxas /tmp/ccYNgEEN.o, line 51; error : Alignment of argument does not
match formal parameter '%in_ar0'
ptxas /tmp/ccYNgEEN.o, line 44; error : Unknown symbol '%stack'
ptxas fatal : Ptx assembly aborted due to errors
nvptx-as: ptxas returned 255 exit status
'gfortran.fortran-torture/compile/pr37236.f':
ptxas [...]/build-gcc/gcc/testsuite/gfortran/pr37236.o, line 269; error :

These are now all-PASS.
In the nvptx target gfortran test suite logs remain however dozens more similar
instances. I've not checked if what's underlying those would also be exposing
the same kind of LTO problem.
