Richard Smith [Wed, 19 Oct 2016 22:18:42 +0000 (22:18 +0000)]
Add optimization to sizeof...(X) handling: if none of parameter pack X's
corresponding arguments are unexpanded pack expansions, we can compute the
result without substituting them. This significantly improves the memory usage
and performance of make_integer_sequence implementations that do this kind of
thing:

  using result = integer_sequence<T, Ns ..., sizeof...(Ns) + Ns ...>;

... but note that such an implementation will still perform O(sizeof...(Ns)^2)
work while building the second pack expansion (we just have a somewhat lower
constant now).

In principle we could get this down to linear time by caching whether the
number of expansions of a pack is constant, or checking whether we're within an
alias template before scanning the pack for pack expansions (since that's the
only case in which we do substitutions within a dependent context at the
moment), but this patch doesn't attempt that.

[CUDA] When we emit an error that might have been deferred, also print a callstack.

Summary:
Previously, when you did something not allowed in a host+device function
and then caused it to be codegen'ed, we would print out an error telling
you that you did something bad, but we wouldn't tell you how we decided
that the function needed to be codegen'ed.

This change causes us to print out a callstack when emitting deferred
errors.  This is immensely helpful when debugging highly-templated code,
where it's often unclear how a function became known-emitted.

We only print the callstack once per function, after we print the all
deferred errors.

This patch also switches all of our hashtables to using canonical
FunctionDecls instead of regular FunctionDecls.  This prevents a number
of bugs, some of which are caught by tests added here, in which we
assume that two FDs for the same function have the same pointer value.

[CUDA] Fix false-positive in known-emitted handling.

Previously: When compiling for host, our constructed call graph went
*through* kernel calls.  This meant that if we had

  host calls kernel calls HD

we would incorrectly mark the HD function as known-emitted on the host
side, and thus perform host-side checks on it.

Fixing this exposed another issue, wherein when marking a function as
known-emitted, we also need to traverse the callgraph of its template,
because non-dependent calls are attached to a function's template, not
its instantiation.
