Matheus Izvekov [Wed, 25 May 2022 20:00:58 +0000 (22:00 +0200)]
[clang] template / auto deduction deduces common sugar

After upgrading the type deduction machinery to retain type sugar in
D110216, we were left with a situation where there is no general
well behaved mechanism in Clang to unify the type sugar of multiple
deductions of the same type parameter.

So we ended up making an arbitrary choice: keep the sugar of the first
deduction, ignore subsequent ones.

In general, we already had this problem, but in a smaller scale.
The result of the conditional operator and many other binary ops
could benefit from such a mechanism.

This patch implements such a type sugar unification mechanism.

The basics:

This patch introduces a `getCommonSugaredType(QualType X, QualType Y)`
method to ASTContext which implements this functionality, and uses it
for unifying the results of type deduction and return type deduction.
This will return the most derived type sugar which occurs in both X and
Y.

Example:

Suppose we have these types:
```
using Animal = int;
using Cat = Animal;
using Dog = Animal;

using Tom = Cat;
using Spike = Dog;
using Tyke = Dog;
```
For `X = Tom, Y = Spike`, this will result in `Animal`.
For `X = Spike, Y = Tyke`, this will result in `Dog`.

How it works:

We take two types, X and Y, which we wish to unify as input.
These types must have the same (qualified or unqualified) canonical
type.

We dive down fast through top-level type sugar nodes, to the
underlying canonical node. If these canonical nodes differ, we
build a common one out of the two, unifying any sugar they had.
Note that this might involve a recursive call to unify any children
of those. We then return that canonical node, handling any qualifiers.

If they don't differ, we walk up the list of sugar type nodes we dived
through, finding the last identical pair, and returning that as the
result, again handling qualifiers.

Note that this patch will not unify sugar nodes if they are not
identical already. We will simply strip off top-level sugar nodes that
differ between X and Y. This sugar node unification will instead be
implemented in a subsequent patch.

This patch also implements a few users of this mechanism:
* Template argument deduction.
* Auto deduction, for functions returning auto / decltype(auto), with
  special handling for initializer_list as well.

Further users will be implemented in a subsequent patch.

22 months ago[libc][math] Improve sinhf and coshf performance.
Tue Ly [Thu, 15 Sep 2022 05:00:13 +0000 (01:00 -0400)]
[libc][math] Improve sinhf and coshf performance.

Optimize `sinhf` and `coshf` by computing exp(x) and exp(-x) simultaneously.

Currently `sinhf` and `coshf` are implemented using the following formulas:
```
  sinh(x) = 0.5 *(exp(x) - 1) - 0.5*(exp(-x) - 1)
  cosh(x) = 0.5*exp(x) + 0.5*exp(-x)
```
where `exp(x)` and `exp(-x)` are calculated separately using the formula:
```
  exp(x) ~ 2^hi * 2^mid * exp(dx)
         ~ 2^hi * 2^mid * P(dx)
```
By expanding the polynomial `P(dx)` into even and odd parts
```
  P(dx) = P_even(dx) + dx * P_odd(dx)
```
we can see that the computations of `exp(x)` and `exp(-x)` have many things in common,
namely:
```
  exp(x)  ~ 2^(hi + mid) * (P_even(dx) + dx * P_odd(dx))
  exp(-x) ~ 2^(-(hi + mid)) * (P_even(dx) - dx * P_odd(dx))
```
Expanding `sinh(x)` and `cosh(x)` with respect to the above formulas, we can compute
these two functions as follow in order to maximize the sharing parts:
```
  sinh(x) = (e^x - e^(-x)) / 2
          ~ 0.5 * (P_even * (2^(hi + mid) - 2^(-(hi + mid))) +
                  dx * P_odd * (2^(hi + mid) + 2^(-(hi + mid))))
  cosh(x) = (e^x + e^(-x)) / 2
          ~ 0.5 * (P_even * (2^(hi + mid) + 2^(-(hi + mid))) +
                  dx * P_odd * (2^(hi + mid) - 2^(-(hi + mid))))
```
So in this patch, we perform the following optimizations for `sinhf` and `coshf`:
  # Use the above formulas to maximize sharing intermediate results,
  # Apply similar optimizations from https://reviews.llvm.org/D133870

[DWARFLinker][NFC] Set the target DWARF version explicitly.

Currently, DWARFLinker determines the target DWARF version internally.
It examines incoming object files, detects maximal
DWARF version and uses that version for the output file.
This patch allows explicitly setting output DWARF version by the consumer
of DWARFLinker. So that DWARFLinker uses a specified version instead
of autodetected one. It allows consumers to use different logic for
setting the target DWARF version. f.e. instead of the maximally used version
someone could set a higher version to convert from DWARFv4 to DWARFv5
(This possibility is not supported yet, but it would be good if
the interface will support it). Or another variant is to set the target
version through the command line. In this patch, the autodetection is moved
into the consumers(DwarfLinkerForBinary.cpp, DebugInfoLinker.cpp).

[lld-macho] Add support for N_INDR symbols

This is similar to the `-alias` CLI option, but it gives finer-grained
control in that it allows the aliased symbols to be treated as private
externs.

While working on this, I realized that our `-alias` handling did not
cover the cases where the aliased symbol is a common or dylib symbol,
nor the case where we have an undefined that gets treated specially and
converted to a defined later on. My N_INDR handling neglects this too
for now; I've added checks and TODO messages for these.

`N_INDR` symbols cropped up as part of our attempt to link swift-stdlib.
