[libc++] Explicitly enumerate std::string external instantiations.2020-01-09T20:51:02+00:00Eric Fiseliereric@efcs.ca2020-01-09T20:50:55+00:00urn:sha1:61bd19206f61ace4b007838a2ff8884a13ec0374
The external instantiation of std::string is a problem for libc++.
Additions and removals of inline functions in string can cause ABI
breakages, including introducing new symbols.
This patch aims to:
(1) Make clear which functions are explicitly instatiated.
(2) Prevent new functions from being accidentally instantiated.
(3) Allow a migration path for adding or removing functions from the
explicit instantiation over time.
Although this new formulation is uglier, it is preferable from a
maintainability and readability standpoint because it explicitly
enumerates the functions we've chosen to expose in our ABI. Changing
this list is non-trivial and requires thought and planning.
(3) is achieved by making it possible to control the extern template declaration
separately from it's definition. Meaning we could add a new definition to
the dylib, wait for it to roll out, then add the extern template
declaration to the header. Similarly, we could remove existing extern
template declarations while still keeping the definition to prevent ABI
breakages.

Update the file headers across all of the LLVM projects in the monorepo2019-01-19T08:50:56+00:00Chandler Carruthchandlerc@gmail.com2019-01-19T08:50:56+00:00urn:sha1:2946cd701067404b99c39fb29dc9c74bd7193eb3
to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

[Libc++] Use #pragma push_macro/pop_macro to better handle min/max on Windows2017-05-31T22:07:49+00:00Eric Fiseliereric@efcs.ca2017-05-31T22:07:49+00:00urn:sha1:a016efb1dcda61e606e527b73791fbacf1bc9c86
Summary:
This patch improves how libc++ handles min/max macros within the headers. Previously libc++ would undef them and emit a warning.
This patch changes libc++ to use `#pragma push_macro` to save the macro before undefining it, and `#pragma pop_macro` to restore the macros and the end of the header.
