josh11b 9c8fd6864e Implement rename me -> self (#2444) 
Implements change proposed in #1382

Replaces #1624

Richard Smith 9e8cacae00 Implement support for named constraints (#2359) 
Basic support for named constraints as described in [the generics design](https://github.com/carbon-language/carbon-lang/blob/trunk/docs/design/generics/details.md#named-constraints). Support is provided for `extends` and `impl` declarations in `constraint`, but not yet for member aliases.

The missing prelude named constraints `Add`, `Mul`, `Ordered`, etc. are also added.

Richard Smith 4b679510e7 Check equality constraints when checking whether a constraint is satisfied (#2294) 
Add checking that a type only satisfies a constraint if it satisfies all of that constraint's equality and rewrite constraints.

Enforce the rule that `=` must be used in impls when specifying associated constant values rather than `==`.

Turn off the pre-#2173 single-step equality behavior. This is getting somewhat ahead of the approved design, but it's a one-line change to restore the old behavior.

Fix `CARBON_CHECK` to handle top-level `,`s in its argument, such as may happen in template argument lists, as this change introduces such a check.

Richard Smith 7f7b9a4086 Implement support for extends and impl as declarations in interfaces (#2279) 2022-10-12 17:13:25 -07:00
Richard Smith 9f534ae004 Implement support for rewrite constraints (#2276) 
Implements basic support for rewrite constraints as proposed in #2173.

Support for associated constants and complex constraints in general is also made more robust: argument deduction now properly computes and substitutes witnesses, and interface declarations track a more correct description of the constraint that they introduce than the one we previously built.

Junhee Cho 69d4363ea5 Adds division to multiplicative expression. (#2091) 
* Multiplication and division have the same priority.
* A new builtin interface DivWith is added.
* In some tests expecting a compilation error (syntax error), the error
  message now says it is expecting SLASH or binary *.

Richard Smith e26bc32343 Change remaining uses of Bool to bool, following #750. (#1901) 
The most significant change here is that explorer now uses the chosen spelling
rather than the old `Bool` spelling. Also update a few documentation examples
and some skeletal design docs to use the chosen spelling.

Richard SmithandJon Ross-Perkins ef96f60425 Add support for bitwise operators. (#1809) 
Following #1191, add initial support for bitwise operators. Support for both
integer operations and for operator overloading via the interfaces specified in
#1191 is provided.

Richard Smith 15ec5113aa Add extensibility support for arithmetic operators. (#1751) 
Add new prelude interfaces `Negate`, `AddWith`, `SubWith`, and `MulWith`, and
use them to implement non-builtin arithmetic operations.

Jon Ross-Perkins 084bc6ebc1 Restructure __intrinsic_print to be a keyword-like Print (#1407) 2022-07-18 13:58:08 -04:00
Jon Ross-Perkins a41915b5af Support basic int printing (#1405) 
We don't have overload resolution, so I've simply added PrintInt for now. But it's really tempting to turn __intrinsic_print into a total kludge function.

Richard Smith 8dd398807d Support user-defined implicit conversions via ImplicitAs (#1273) 
Support is added for all of the non-type expression contexts where we currently accept built-in conversions, such as reordering the fields in a struct.
