Hi.

The patch allows DCE to remove only replaceable operators new and delete.
That's achieved by proper mark up of all these operators in C++ FE.
The patch also brings all tests we've collected so far for the PR.

Patch can bootstrap on x86_64-linux-gnu and survives regression tests.

Ready to be installed?

Grepping for uses of DECL_IS_OPERATOR_* reveals you miss comparing
the new flag in ipa-icf.c and cgraph node dumping in cgraph.c might want
to dump it as well.

Otherwise it looks reasonable.

So the mid-end parts are OK in case FE people are happy with this solution
for GCC 10.

This seems fine for GCC 10, though I wonder about using an attribute for
DECL_REPLACEABLE_OPERATOR rather than taking a bit in all FUNCTION_DECLs
that will only ever be set on a small handful.

If it is just for GCC 10 and we'll return the bit back to unused in GCC 11,
I'd think it is acceptable.

Agreed.

Jason


All right, thanks for review. There's updated version of the patch that fullfils
Richi's comments.

Patch can bootstrap on x86_64-linux-gnu and survives regression tests.
I'm going to install the patch.

Thanks,
Martin
