0a6a801dc2 Bug 1294537 - introduce a non-null-checking placement operator new; r=sunfish,nbp 
The default placement operator new is defined to always require that its
result be null-checked.  A sufficiently smart compiler can remove this
check, but not all compilers are sufficiently smart.  Better to have a
custom placement operator new that will remove null checks in a way
defined by the standard.

d8dc169af0 Bug 1268754 - Tweak some MFBT return values. r=Ms2ger. 
This patch:

- Adds MOZ_MUST_USE to AllocPolicy::checkSimulatedOOM().

- Adds MOZ_MUST_USE to LZ4::decompress() (both variants) and fixes their
  comments.

- Changes the return type of SplayTree::insert() from bool to void, because it
  always returns true and its callers don't check the return value.

- Changes the return type of SplayTree::finishInsertion() from T* to void,
  because it makes things clearer -- it was just returning the aNew argument.

- Adds MOZ_MUST_USE to a Vector::growTo() (both variants).

2511b2c327 Bug 1267550 (part 2) - Rename MOZ_WARN_UNUSED_RESULT as MOZ_MUST_USE. r=froydnj. 
It's an annotation that is used a lot, and should be used even more, so a
shorter name is better.

4560db90e5 Bug 1170325 - Convert js::Vector into a template alias to mozilla::Vector with a single customized default argument. Also get rid of the CRTP support in mozilla::Vector (through mozilla::VectorBase) now that template aliasing is good enough, and make mozilla::Vector final so that people will use composition and not inheritance with it. (Inheritance plays poorly with movability and a few other things, in addition to messing up template argument deduction matching.) r=Waldo, patch sort of a tag-team between him and me 2015-07-13 12:42:52 -07:00
