Delay the creation of eh_frame so that the user can change the defaults.
Add support for SHT_X86_64_UNWIND.

minor change to rafael's recent patches: if something is
constant but requires a unique address, we can still put it in a
readonly section, just not a mergable one.

llvm-svn: 123711

Only put unnamed_addr constants in mergeable sections. Fixes PR8297.

the latest assembler that runs on powerpc 10.4 machines doesn't
support aligned comm. Detect when compiling for 10.4 and don't
emit an alignment for comm. THis will hopefully fix PR8198.

name.

finally give Mangler a getSymbol method, which returns an MCSymbol
for a global instead of messing around with string buffers.

up with its own names.

fix a fixme in TargetLoweringObjectFile::getExprForDwarfReference
where we used ot create an MCSymbol for ".". Now emit an assembler
temporary label and reference it instead of "." textually.

rename getSymbolForDwarf* to getExprForDwarf* since it returns
an MCExpr and not an MCSymbol. Change it to take an MCStreamer,
which is currently unused.

No functionality change.

move three lowering hooks from MAI to TLOF and make one of them

Cleanup handling of .zerofill on darwin:

1. TargetLoweringObjectFileMachO should decide if something
goes in zerofill instead of having every target do it.
2. TargetLoweringObjectFileMachO should assign said symbols to
the right MCSection, the asmprinters should just emit to the
right section.
3. Since all zerofill stuff goes through mcstreamer anymore,
MAI can have a bool "haszerofill" instead of having the textual
directive to emit.

the other one.
