Since this is inside a string literal, backslashes that are part of
regex syntax have to be escaped. But that's ugly, so convert to a raw
string instead.
Actually, two enum classes, since for some reason there are two separate
yet identical `PollFD` types used in the codebase. I get that one is
ABI-compatible with the Switch while the other is an abstract type used
for the host, but why not use `WSAPOLLFD` directly for the latter?
Anyway, why make this change? Because on Apple platforms, `POLL_IN`,
`POLL_OUT`, etc. (with an underscore) are defined as macros in
<sys/signal.h>. (This is inherited from FreeBSD.) So defining
a variable with the same name causes a compile error.
I could just rename the variables, but while I was at it I thought I
might as well switch to an enum for stronger typing.
Also, change the type used for values copied directly to/from the
`events` and `revents` fields of the host *native*
`pollfd`/`WSASPOLLFD`, from `u32` to `short`, as `short` is the correct
canonical type on both Unix and Windows.
`PhysicalCore`'s move assignment operator was declared as `= default`,
but was implicitly deleted because `PhysicalCore` has fields
of reference type. Switch to explicitly deleting it to avoid a Clang
warning.
The move *constructor* is still defaulted, and is required to exist due
to the use of `std::vector<PhysicalCore>`.
- Add a type check so that calling Push with an invalid type produces a
compile error rather than a linker error.
- vi.cpp was calling Push with a variable of type `std::size_t`.
There's no explicit overload for `size_t`, but there is one for `u64`,
which on most platforms is the same type as `size_t`. On macOS,
however, it isn't: both types are 64 bits, but `size_t` is `unsigned
long` and `u64` is `unsigned long long`. Regardless, it makes more
sense to explicitly use `u64` here instead of `size_t`.
The previous definition was:
#define NUM(field_name) (sizeof(Maxwell3D::Regs::field_name) / sizeof(u32))
In cases where `field_name` happens to refer to an array, Clang thinks
`sizeof(an array value) / sizeof(a type)` is an instance of the idiom
where `sizeof` is used to compute an array length. So it thinks the
type in the denominator ought to be the array element type, and warns if
it isn't, assuming this is a mistake.
In reality, `NUM` is not used to get array lengths at all, so there is no
mistake. Silence the warning by applying Clang's suggested workaround
of parenthesizing the denominator.
