`--structs-packed` option
The :vlopt:`--structs-packed` option was introduced when Verilator was
first implementing unpacked structs. That feature has been stable now
for multiple years, so :vlopt:`--structs-packed` should no longer be
used. Thus :vlopt:`--structs-packed` will change to a no-operation flag
and the related :option:`UNPACKED` warning will never be issued no
sooner than September 2026.
tcmalloc support
Verilator currently supports the default malloc, tcmalloc, or jemalloc.
As jemalloc has better performance, support for tcmalloc may be removed

Converts all unpacked structures to packed structures, and issues an
:option:`UNPACKED` warning. Specifying this option allows for backward
compatibility with versions before Verilator 5.006, when Verilator would
always pack unpacked structures.

.. option:: UNPACKED
Warns that unpacked structs and unions are not supported because
:vlopt:`--structs-packed` was used, or by up through version 5.004.
Historical, never issued since version 5.004.
Ignoring this warning will make Verilator treat the structure as packed,
which may make Verilator simulations differ from other simulators. This
downgrading may also result in what would typically be a legal unpacked
struct/array inside an unpacked struct/array becoming an illegal
unpacked struct/array inside a packed struct/array.
Warned that unpacked structs and unions were not supported, or disabled
by the since-removed `--structs-packed` option.
