fmt now automatically prints the numeric value of an enum class member
by default, so we don't need to use casts any more.
Reduces the line noise a bit.
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.
On Apple platforms, FALSE and TRUE are defined as macros by
<mach/boolean.h>, which is included by various system headers.
Note that there appear to be no actual users of the names to fix up.
