Bug ID: 68009
Summary: [6 Regression] prototype for gfortran_runtime_error
with inline matmul
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: tkoenig at gcc dot gnu.org
Target Milestone: ---
A discussion from the gfortran mailing list that never made it into Bugzilla...
See the thread at https://gcc.gnu.org/ml/fortran/2015-07/msg00079.html .
The declaration of gfortran_runtime_error as emitted by the FE is incorrect,
it does not take into account that it is variadic. This is incorrect,
and causes actual problems on nvptx.
A simplistic solution which sets resolved_isym on the symbol introduces even
stranger behavior: The function call is optimized away completele
(see https://gcc.gnu.org/ml/fortran/2015-07/msg00127.html ).
