fix build failure.

llvm-svn: 93628

remove a couple of actively incorrect uses of getMangledName.

llvm-svn: 93627

fix ELF section mangling stuff for weak symbols to not use
obsolete Mangler interfaces.

llvm-svn: 93356

Use the GV version of getNameWithPrefix in TargetLoweringObjectFileCOFF::
SelectSectionForGlobal, unbreaking weak globals with no-name.

llvm-svn: 93336

add a fixme, ELF MCSection isn't quite right and weak unnamed globals are broken
on linux (even though they are pointless, they shouldn't ICE).

change Mangler::makeNameProper to return its result in a SmallVector
instead of returning it in an std::string. Based on this change:

1. Change TargetLoweringObjectFileCOFF::getCOFFSection to take a StringRef
2. Change a bunch of targets to call makeNameProper with a smallstring,
making several of them *much* more efficient.
3. Rewrite Mangler::makeNameProper to not build names and then prepend
prefixes, not use temporary std::strings, and to avoid other crimes.

We need to put any kind of data with a relocation into a

The "ReadOnlyWithRel" enum seems to apply more to what Darwin does with the EH
exception table than DataRel.

llvm-svn: 89279

Attempt #2:

Place the EH table in the __TEXT section on MachO. It saves space.

It's inefficient to have place the exception tables (which contain the LSDA)
into the __DATA section. At launch time, dyld has to update most of the section
to fix up the type info pointers. It's better to place it into the __TEXT
section and use pc-rel indirect pointer encodings. Similar to the personality
routine.

Big change #1 for personality function references:
Eliminate the PersonalityPrefix/Suffix & NeedsIndirectEncoding
fields from MAI: they aren't part of the asm syntax, they are
related to the structure of the object file.

To replace their functionality, add a new
TLOF::getSymbolForDwarfGlobalReference method which asks targets
to decide how to reference a global from EH in a pc-relative way.

The default implementation just returns the symbol. The default
darwin implementation references the symbol through an indirect
$non_lazy_ptr stub. The bizarro x86-64 darwin specialization
handles the weird "foo@GOTPCREL+4" hack.

DwarfException.cpp now uses this to emit the reference to the
symbol in the right way, and this also eliminates another
horrible hack from DwarfException.cpp:

- if (strcmp(MAI->getPersonalitySuffix(), "+4@GOTPCREL"))
- O << "-" << MAI->getPCSymbol();
