History
Bob Wilson 98c9fb94ab Record CodeGen optimization level in the BranchFolding pass so that we can 
use it to control tail merging when there is a tradeoff between performance
and code size.  When there is only 1 instruction in the common tail, we have
been merging.  That can be good for code size but is a definite loss for
performance.  Now we will avoid tail merging in that case when the
optimization level is "Aggressive", i.e., "-O3".  Radar 7338114.

Since the IfConversion pass invokes BranchFolding, it too needs to know
the optimization level.  Note that I removed the RegisterPass instantiation
for IfConversion because it required a default constructor.  If someone
wants to keep that for some reason, we can add a default constructor with
a hard-wired optimization level.

AntiDepBreaker.h Allow the aggressive anti-dep breaker to process the same region multiple times. This is necessary because new anti-dependencies are exposed when "current" ones are broken. 2009-10-26 22:31:16 +00:00
AsmPrinter.h Update processDebugLoc() so that it can be used to process debug info before and after printing an instruction. 2009-10-06 02:19:11 +00:00
BinaryObject.h Move DataTypes.h to include/llvm/System, update all users. This breaks the last 2009-10-26 01:35:46 +00:00
BreakCriticalMachineEdge.h
CallingConvLower.h Retype from unsigned to CallingConv::ID accordingly. Approved by Bob Wilson. 2009-09-02 08:44:58 +00:00
DAGISelHeader.h
DwarfWriter.h Add support to handle debug info attached to an instruction. 2009-10-06 18:37:31 +00:00
