In the disassembler C API, be careful not to confuse the comment streamer that the disassembler outputs annotations on with the streamer that the InstPrinter will print them on.

Don't attach annotations to MCInst's.  Instead, have the disassembler return, and the printer accept, an annotation string which can be passed through if the client cares about annotations.

The the MC disassembler C API to print in verbose mode.  Perhaps there should be a parameter to request verbose mode?

llvm-svn: 139821

Add support for stored annotations to MCInst, and provide facilities for MC-based InstPrinters to print them out.  Enhance the ARM and X86 InstPrinter's to do so in verbose mode.

Assembler private local symbols aren't legal targets of symbol attributes,
so issue a diagnostic for them.

If we see an EOF w/o a preceding end-of-line, return an EndOfStatement
token before returning the Eof token.

#line directives with the needed support in the lexer.  Next will be to build
a simple file/line# table mapping source SMLoc's for later use by diagnostics.
And the last step will be to get the diagnostics to use the mapping for file
and line numbers.

- On COFF the .lcomm directive has an alignment argument.
- On ELF we fall back to .local + .comm

Fixes PR9337, PR9483 and PR10128.

Fix apparent build error caused by r138948 on certain versions of GCC with -Werror. Sorry for the inconvenience.

In the case of EDInstInfo, this would actually cause a bug when -1 became 255
and was then compared >=0 in llvm-mc/Disassembler.cpp.

Teach MC / dwarf emission to handle these cfi directives which essentially
create an empty frame.

MachOWriter: Don't crash on fixups with arithmetic, emit a relocation instead. This matches what as does.

Assigned symbol addresses get truncated to 32-bits, even on 64-bit platforms.
That's obviously bogus.
For example,

This is meant to be overriden by backends. Implement an override on PowerPC
which adjusts the offset by 2 for ha16/lo16 relocation kinds. This removes
a commented out hack and enables hello world to be compiled on PowerPC.

them properly. Specifically, the disassembler clearly attempts to
initialiaze all TargetInfo, MCTargeDesc, AsmParser, and Disassembler
sublibraries of registered targets. This makes the CMakeLists accurately
reflect this intent in the code.

This should fix the last of the link errors that I have gotten reports
of on OS X, but if anyone continues to see link errors, continue to
pester me and I'll look into it.
