Re: r307232 - [modules ts] Do not emit strong function definitions from the module interface unit in every user.

2017-07-16 Thread David Blaikie via cfe-commits

Looks good - does this support available_externally definitions of strong
external linkage functions in the users of a module? (is that tested?)
Should it?

Also should we consider having two flags for modular codegen - one for
correctness (external function definitions), one for linkage size
optimization (inline functions). Given the current data on optimized builds
with inline functions (that it hurts object size to emit
weak+available_externally definitions rather than linkonce_odr because so
many definitions are optimized away entirely, that the bytes for the weak
definition are wasted/unnecessary) - or at least something to keep in
mind/run numbers on in the future for more generic codebases than Google's
protobuf-heavy (& only protobuf modularized) code.

[PATCH] D35472: Implement P0463R1: "Endian just Endian"

2017-07-16 Thread Marshall Clow via Phabricator via cfe-commits

mclow.lists created this revision.

Implement the C++2a feature "A compile time endian-ness detection idiom"
Howard's suggested implementation is:

enum class endian
{
#ifdef _WIN32

little = 0,
big= 1,
native = little

#else

little = __ORDER_LITTLE_ENDIAN__,
big= __ORDER_BIG_ENDIAN__
native = __BYTE_ORDER__,

#endif
};

but libc++ has it's own macros that have done the work to detect this.

The other option would be to rip out `_LIBCPP_LITTLE_ENDIAN` and 
`_LIBCPP_BIG_ENDIAN`, which is tempting, but that would entail changes in code 
that has to compile for earlier C++ language versions.

I suppose you may as well pick a new name for "string_ref" that doesn't have 
underscores, since it's a new type, if someone is going to follow up to drop 
underscores.  Perhaps "StringView"?

glenjofe created this revision.
glenjofe created this object with edit policy "No One".

A tiny patch that implements P0653R0 (or D0653R1 which revises the former with 
only a small editorial change after LEWG review).

r308157 - [NFC] Refactor the Preprocessor function that handles Macro definitions and rename Arguments to Parameters in Macro Definitions.

2017-07-16 Thread Faisal Vali via cfe-commits

Author: faisalv

URL: http://llvm.org/viewvc/llvm-project?rev=308157=rev
Log:
[NFC] Refactor the Preprocessor function that handles Macro definitions and 
rename Arguments to Parameters in Macro Definitions. 
  - Extracted the reading of the tokens out into a separate function.
  - Replace 'Argument' with 'Parameter' when referring to the identifiers of 
the macro definition (as opposed to the supplied arguments - MacroArgs - during 
the macro invocation).

This is in preparation for submitting patches for review to implement 
__VA_OPT__ which will otherwise just keep lengthening the HandleDefineDirective 
function and making it less comprehensible.


Thanks!

Re: r308044 - Add documentation for @available

2017-07-16 Thread Nico Weber via cfe-commits

Aaron, https://clang.llvm.org/docs/AttributeReference.html#availability
still doesn't have the AttrDocs.td change I made in this change 2 days ago.
Do I have to do anything to get it to update?

[PATCH] D35462: Also add the option -no-pie (like -nopie)

2017-07-16 Thread Sylvestre Ledru via Phabricator via cfe-commits

sylvestre.ledru created this revision.

For example, this option is expected by ghc (haskell compiler). Currently, 
building with ghc will fail with:

  clang: error: unknown argument: '-no-pie'
  `gcc' failed in phase `Linker'. (Exit code: 1)
  . /usr/share/haskell-devscripts/Dh_Haskell.sh && \
  configure_recipe

This won't do anything (but won't fail with an error)
