Do not use '&' prefix for globals when register base field is non-zero, otherwise msp430-as will silently miscompile the code (TI's assembler report an error though).2010-03-06T11:41:12ZAnton Korobeynikovasl@math.spbu.ru2010-03-06T11:41:12Zurn:sha1:9aff323a074658eee2de69862d202a8638b59c05

Don't emit global symbols into the (__TEXT,__ustring) section on Darwin. This2010-03-05T22:28:45ZCharles Daviscdavis@mines.edu2010-03-05T22:28:45Zurn:sha1:314fef6127a18db9f8c39f0081566f49c70a15f0
is a workaround for <rdar://problem/7672401/> (which I filed).
This let's us build Wine on Darwin, and it gets the Qt build there a little bit
further (so Doug says).

Better handling of dead super registers in LiveVariables. We used to do this:2010-03-05T21:49:17ZJakob Stoklund Olesenstoklund@2pi.dk2010-03-05T21:49:17Zurn:sha1:53e000bac319a25f7c13ec8b7b413418fba5ef20
CALL ... %RAX<imp-def>
... [not using %RAX]
%EAX = ..., %RAX<imp-use, kill>
RET %EAX<imp-use,kill>
Now we do this:
CALL ... %RAX<imp-def, dead>
... [not using %RAX]
%EAX = ...
RET %EAX<imp-use,kill>
By not artificially keeping %RAX alive, we lower register pressure a bit.
The correct number of instructions for 2008-08-05-SpillerBug.ll is obviously
55, anybody can see that. Sheesh.
