Bug ID: 109447
Summary: test case libffi.closures/cls_align_longdouble_split.c
fails
Product: gcc
Version: 12.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libffi
Assignee: unassigned at gcc dot gnu.org
Reporter: seurer at gcc dot gnu.org
Target Milestone: ---
When running make check on libffi there are two failures. Note that this only
occurs on systems where the compiler was built with
--with-long-double-format=ieee. I see these on both gcc 12 and trunk. I don't
know yet if it is a regression but I am checking.
On powerpc the libffi library is built and tested if go is included in the
languages.
