Fix TableGen so that it will emit the correct signature for FastEmit_f:

ConstantFP*. This doesn't affect anything in the tree, since nothing causes that

Jakob Stoklund Olesen [Sat, 7 Jan 2012 07:39:50 +0000 (07:39 +0000)]
Optimize reserved register coalescing.

Reserved registers don't have proper live ranges, their LiveInterval
simply has a snippet of liveness for each def.  Virtual registers with a
single value that is a copy of a reserved register (typically %esp) can
be coalesced with the reserved register if the live range doesn't
overlap any reserved register defs.

When coalescing with a reserved register, don't modify the reserved
register live range.  Just leave it as a bunch of dead defs.  This
eliminates quadratic coalescer behavior in i386 functions with many
function calls.

Sean Callanan [Fri, 6 Jan 2012 18:24:47 +0000 (18:24 +0000)]
Fixed a bug where the DWARF location expression
parser was creating malformed resuls.  When the
location of a variable is computed by reading a
register and adding an offset, we shouldn't say
that the variable's value is located in that
register.  This was confusing the expression
parser when trying to read a variable captured
by a block.
