--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> 2012-01-05 11:21:38 UTC ---
Reduced testcase (-O -m32):
struct S { unsigned int len; };
struct S foo (struct S);
struct S
bar (struct S x)
{
return ({ struct S a = x; foo (a); });
}
The C FE isn't inserting CLEANUP_POINT_EXPRs everywhere, so I wonder if the
r181332 change to add the clobber must not be limited to C++ or if e.g.
gimplify_cleanup_point_expr shouldn't set some (new) flag in *gimplify_ctxp for
the duration of the embedded gimplify_stmt call (and restore it from previous
value afterwards) and use this flag to decide whether to add the cleanup or
not.

Created attachment 26249
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=26249
gcc47-pr51761.patch
Untested fix. With the exception of C++/Obj-C++ FEs I'm afraid other FEs don't
add all the needed CPEs.
