Now that it behaves itself in terms of streamer independence (r172450), this
method can be moved to MCAsmParser to be available to all extensions,
overriding, etc.

The aim of this patch is to fix the following piece of code in the
platform-independent AsmParser:
void AsmParser::CheckForValidSection() {
if (!ParsingInlineAsm && !getStreamer().getCurrentSection()) {
TokError("expected section directive before assembly directive");
Out.SwitchSection(Ctx.getMachOSection(
"__TEXT", "__text",
MCSectionMachO::S_ATTR_PURE_INSTRUCTIONS,
0, SectionKind::getText()));
}
}
This was added for the "-n" option of llvm-mc.
The proposed fix adds another virtual method to MCStreamer, called
InitToTextSection. Conceptually, it's similar to the existing
InitSections which initializes all common sections and switches to
text. The new method is implemented by each platform streamer in a way
that it sees fit. So AsmParser can now do this:
void AsmParser::CheckForValidSection() {
if (!ParsingInlineAsm && !getStreamer().getCurrentSection()) {
TokError("expected section directive before assembly directive");
Out.InitToTextSection();
}
}
Which is much more reasonable.

Since it's used by extensions. One further step to fully decoupling
GenericAsmParser from an intimate knowledge of the internals of AsmParser,
pointing it to the MCASmParser interface instead (like all other parser
extensions do).
Since this change moves the MacroArgument type to the interface header, it's
renamed to be a bit more descriptive in a general context.

This was previously added to support -[NSAutoreleasePool drain], which
behaves like -release under non-GC and "please collect" under GC. We're
not currently modeling the autorelease pool stack, though, so we can
just take this out entirely.
Fixes PR14927.

!0 = metadata !{metadata !"-lautolink"}
!1 = metadata !{metadata !"-framework", metadata !"autolink_framework"}
referenced from llvm.module.linkoptions, e.g.,
!llvm.module.linkoptions = !{!0, !1, !2, !3}
This conceptually moves the logic for figuring out the syntax the
linker will accept from LLVM into Clang. Moreover, it makes it easier
to support MSVC's
#pragma comment(linker, "some option")
in the future, should anyone care to do so.

The methods are also exposed via the MCAsmParser interface, which allows more
than one client to control them. Previously, GenericAsmParser was playing with
a member var in AsmParser directly (by virtue of being its friend).

will have a shared library with the same name as its framework (and no
suffix!) within its .framework directory. Detect this both when
inferring the whole top-level framework and when parsing a module map.

the 64-bit PowerPC ELF ABI.
The ABI requires that the real and imaginary parts of a complex argument
each occupy their own doubleword. Arguments smaller than 8 bytes are
right-adjusted within the doubleword.
Clang expects EmitVAARG() to return a pointer to a structure in which
the real and imaginary parts are packed adjacently in memory. To accomplish
this, we generate code to load the code appropriately from the varargs
location and pack the values into a temporary variable in the form Clang
expects, returning a pointer to that structure.
The test case demonstrates correct code generation for all "small" complex
types on PPC64: int, short, char, and float.

metadata for linking against the libraries/frameworks for imported
modules.
The module map language is extended with a new "link" directive that
specifies what library or framework to link against when a module is
imported, e.g.,
link "clangAST"
or
link framework "MyFramework"
Importing the corresponding module (or any of its submodules) will
eventually link against the named library/framework.
For now, I've added some placeholder global metadata that encodes the
imported libraries/frameworks, so that we can test that this
information gets through to the IR. The format of the data is still
under discussion.

We now format this correctly:
Status::Rep Status::global_reps[3] = {
{ kGlobalRef, OK_CODE, NULL, NULL, NULL },
{ kGlobalRef, CANCELLED_CODE, NULL, NULL, NULL },
{ kGlobalRef, UNKNOWN_CODE, NULL, NULL, NULL }
};
- fixed a bug where BreakBeforeClosingBrace would be set on the wrong
state
- added penalties for breaking between = and {, and between { and any
other non-{ token

Now, "if (a) return;" is only allowed, if this option is set.
Also add a Chromium style which is currently identical to Google style
except for this option.

Specify weaker memory order in case we optimize for it in the future,
presently still doing same __sync_lock_test_and_set() as before.
Change suggested by Alexey Samsonov, thanks!
llvm-svn: 172429
Before: if (a)
return;
After: if (a) return;
Not yet sure, whether this is always desired, but we can add options and
make this a style parameter as we go along.

"Added dumping of declaration comments in ASTDumper. This required moving the
comment dumping code from CommentDumper so that the indentation is correct."

Main difference, add an AnnotatedLine class to hold information about a
line while formatting. At the same time degrade the UnwrappedLine class
to a class solely used for communicating between the UnwrappedLineParser
and the Formatter.
No functional changes intended.
