use the new "exact" sdiv to allow LLVM optimization to perform

the AST, and create such declarations.

llvm-svn: 78719

that uses "dot syntax" since it might have a side effect.

copying in copy constructors and used in
default constructor's initializer list.

llvm-svn: 78674

FriendFunctionDecl, and create instances as appropriate.

The design of FriendFunctionDecl is still somewhat up in the air;  you can
befriend arbitrary types of functions --- methods, constructors, etc. ---
and it's not clear that this representation captures that very well.
We'll have a better picture when we start consuming this data in access
control.

llvm-svn: 78653

generic tree transformation (also used for recanonicalization) and a
small amount of template-instantiation-specific logic.

llvm-svn: 78645

llvm-svn: 78644

virtual base primaries and improve the layout of classes with virtual
bases.  WIP.

Hey, I've decided I want a change to FileCheck, I need to ensure that
the group is together, nothing in between.  Can we change it to check
the match line is from the line immediately following the last matched
line, if the source for the matched line is immediately after the
source for the previously matched line?

// CHECK: 1
// CHECK: 2
// CHECK: 3

// CHECK: 4
// CHECK: 5
// CHECK: 6

would require 1 2 and 3 to be continuous in the output, and 4 5 and 6
to be continuous.

Fixes PR4704 problems

Addresses Eli's patch feedback re: ugly cast code

Updates all postfix operators to remove ParenListExprs.  While this is awful,
no better solution (say, in the parser) is obvious to me.  Better solutions
welcome.

llvm-svn: 78621

Add a CastInfo struct that will be used for cast information when constructing cast expressions. Right now it only stores the cast kind, but in the future it might store conversion functions and constructors.

1. Passing something that isn't a string used to cause:
   "argument to annotate attribute was not a string literal"
  make it say "section attribute" instead.

2. Fix the location of the above message to point to the
   bad argument instead of the section token.

3. Implement rdar://4341926, by diagnosing invalid section
   specifiers in the frontend rather than letting them slip all
   the way to the assembler (a QoI win).

An example of #3 is that we used to produce something like this:

/var/folders/n7/n7Yno9ihEm894640nJdSQU+++TI/-Tmp-//ccFPFGtT.s:2:Expected comma after segment-name
/var/folders/n7/n7Yno9ihEm894640nJdSQU+++TI/-Tmp-//ccFPFGtT.s:2:Rest of line ignored. 1st junk character valued 46 (.).

Daniel improved clang to use llvm_report_error, so now we got:

$ clang t.c -c
fatal error: error in backend: Global variable 'x' has an invalid section specifier 'sadf': mach-o section specifier
      requires a segment and section separated by a comma.

with no loc info.  Now we get:

$ clang t.c -fsyntax-only
t.c:4:30: error: argument to 'section' attribute is not valid for this target: mach-o section specifier requires a segment
      and section separated by a comma
int x __attribute__((section("sadf")));
                             ^

which is nice :)

initializer syntax used by OpenCL, so that vector literals are compatible
