Fix the one remaining site that was redirected by this. Remove the
redirection macro, so that the literal and variadic forms can have
differing types for their string field.
Adjust code_window_point to use the same masks as clipping_code.
Previously, it had top and bottom swapped. However, since its output
was only ever compared for equality to 0, this transposition should not
affect the observable behavior.
Change piggy_register_sound to take the sound offset as a parameter,
rather than assuming the caller will set SoundOffset accordingly.
Remove a spurious sound reset in piggy_register_bitmap. Based on the
duplicated comment, this was probably incorrectly copied from
piggy_register_sound, where it made sense, into piggy_register_bitmap,
where it does not.
- Document the logic for resetting the values to default
- For D1: load the untrusted values directly into an array, instead of
loading them to temporaries and then copying the temporaries to the
array.
- For D2: optimize the read by loading 22 bytes in a single step,
instead of loading single bytes 22 times.
Descent 2: Vertigo level 10 has invalid data in its control center
triggers. Sanitize invalid data at load to avoid problems in
memory-poisoning builds.
`oldsegnum` is `const`, so the address computed from it cannot change.
Lift the computation of `auto &children` out of the loop.
Reduce the scope of `biggest_val`, since it does not need to outlive the
loop.
Introduce a helper to obtain both the magnitude of a vector and the
corresponding normalized vector. Use it to capture both values as const
when possible.
gcc-11.3.0 issues a -Wmaybe-uninitialized warning for `exit_side`.
Reorder the code to eliminate this warning. Also, fix a potential
out-of-bounds read if `matt_find_connect_side` returned `side_none`.
Before, this would lead to a read of `Side_opposite[side_none]` before
the test that `entry_side` is not `side_none`. Now, if
`matt_find_connect_side` returns `side_none`, the read of
`Side_opposite` is skipped and logic goes directly to finding a proper
exit side.
gcc-11.3.0 with -Og may issue a -Wmaybe-uninitialized warning for `w1`
because it fails to prove that every path sets the variable. Reorder
the logic to use a local lambda to ensure that every path assigns a
value.
