Bug ID: 120072
Summary: New attribute alloc_variant_zeroed which can be used
for alloc+memset->calloc optimization
Product: gcc
Version: 16.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: middle-end
Assignee: unassigned at gcc dot gnu.org
Reporter: pinskia at gcc dot gnu.org
Target Milestone: ---
Instead of the current hard coded malloc+zero->calloc code. we could have a new
attribute which is used for a similar thing for other allocation
(xmalloc->xcalloc, etc.).
The attribute alloc_variant_zeroed would take 2 arguments:
* first argument is the function that zeros.
* second argument is optional and is a bool (true/false) meaning adding a new
first argument of 1.
