Make AsmStreamer maintain a notion of the current section, pushing it up from the
...
MCAsmStreamer. Based on this, eliminate the current section from AsmPrinter.
While I'm at it, clean up the last of the horrible "switch to null section" stuff
and add an assert. This change is in preparation for completely eliminating
asmprinter::switchtosection.

The attached patches attempt to fix cross builds. For example, if you
...
try to use i686-darwin to build for arm-eabi, you'll quickly run into
several false assumptions that the target OS must be the same as the
host OS. These patches split $(OS) into $(HOST_OS) and $(TARGET_OS) to
help builds like "make check" and the test-suite able to cross
compile. Along the way a target of *-unknown-eabi is defined as
"Freestanding" so that TARGET_OS checks have something to work with.

PowerPC inline asm was emitting two output operands

for a single "m" constraint; this is wrong because the

it should be faster).

change AsmPrinter to switch sections using AsmStreamer instead of

itself, for example.
