__builtin_unreachable.  WIP.

Duncan Sands 7876dad8e7 Pass a value for the isSigned parameter of CreateIntCast, rather than 
passing the name (an exotic way of specifying that the result is signed!).

Mike Stump 876387ba4f __builtin_object_size refinements. Ensure we handle expressions with 
side-effects up front, as when we switch to the llvm intrinsic call
for __builtin_object_size later, it will have two evaluations.

We also finish off the intrinsic version of the code so we can just
turn it on once llvm has the intrinsic.

Mike Stump 7a484dd6a9 Prep for future __builtin_object_size refinements. The theory is that 
someone will add an llvm intrinsic for us to use, so the optimizer can
figure out the hard cases.  WIP.

For those that want to help, double check with Eric before starting.
He has a bit of code this will plug into.

Daniel Dunbar ff0553ec61 Fix subtle bug in generating LLVM function declarations for builtin functions. 
The decl wasn't being passed down, which meant that function attributes were not
being set correctly. This is particularly important for ARM, since it wants to
override the calling convention. Instead we would emit the builtin with the
wrong calling convention, and instcombine would come along and merrily shred all
the calls to it. :)

Argyrios Kyrtzidis b4b64ca752 Remove the ASTContext parameter from the attribute-related methods of Decl. 
The implementations of these methods can Use Decl::getASTContext() to get the ASTContext.

This commit touches a lot of files since call sites for these methods are everywhere.
I used pre-tokenized "carbon.h" and "cocoa.h" headers to do some timings, and there was no real time difference between before the commit and after it.

get rid of a few more clang vector builtins.

Eli Friedman cb9d07caeb Add support for __builtin_unwind_init. 
Also, committing an #if 0'ed __builtin_setjmp and __builtin_longjmp 
implementation I've had sitting in my tree for a while.  I haven't 
enabled it because the LLVM backend support isn't complete yet.

Eli Friedman f6bd15038c If we recognize alloca, treat it as a builtin. This fixes uses of 
alloca without declaring it.

Chris Lattner dc04654697 reimplement __sync_* builtins to be variadic and to follow the same 
semantic rules that gcc and icc use.  This implements the variadic
and concrete versions as builtins and has sema do the 
disambiguation.  There are probably a bunch of details to finish up
but this seems like a large monotonic step forward :)

Daniel Dunbar 8eb018ab9c Support IRgen of sqrt -> llvm.sqrt, pow -> llvm.pow. 
- Define pow[lf]?, sqrt[lf]? as builtins.

 - Add -fmath-errno option which binds to LangOptions.MathErrno

 - Add new builtin flag Builtin::Context::isConstWithoutErrno for
   functions which can be marked as const if errno isn't respected for
   math functions. Sema automatically marks these functions as const
   when they are defined, if MathErrno=0.

 - IRgen uses const attribute on sqrt and pow library functions to
   decide if it can use the llvm intrinsic.
