309650d7ba It's ok to spill a tGPR register as long as it's still allocated a low register.

4df533ba16 fix a minor fixme. When building with SL and later tools, the ".eh" symbols 
don't need to be exported from the .o files.

d56e4482fc When InstCombine simplifies a load -> extract element to gep -> load, place 
the new load by the old load instead of by the extract element because
a store could have occurred between the load and extract element.

f2855aabec Change MCSectionELF to represent a section semantically instead of 
syntactically as a string, very similiar to what Chris did with MachO.
The parsing support and validation is not introduced yet.

ea15a77701 Change the indentation for LLVM Assembly files from 1 tab to 2 spaces. 
This is vaguely consistent with LLVM's own source code, but more
importantly it lets more lines stay within 80 columns.

them, so it doesn't have to explicitly free them.

9c9c3f30bd Now that numbered types have their number printed, it's no longer 
interesting to print the number in a comment. Numbered instructions
don't need their number in a comment either.

Also, tidy up newline printing.

d5c0351c79 Add a new "SDTCisVec" SDTypeConstraint. This complements the vAny type. 
There have been a few times where I've wanted this but ended up leaving the
operand type unconstrained.  It is easy to add this now and should help
catch errors in the future.

9b4700f3ce Make AsmWriter more careful with formatted_raw_ostream so that 
it doesn't leave the underlying stream in unbuffered mode when
the stream was originally buffered.

Also, change WriteAsOperand back to plain raw_ostream. This
lets it work for either formatted_raw_ostream or plain
raw_ostream, so that it doesn't have to force a buffer flush
on a plain raw_ostream.
