[GSoC 2016] [Weekly Status] Interprocedural Register Allocation
...ng too much time
building the llvm it self.
So here is brief summary:
Implementation:
============
The patch has been split into analysis and transformation passes. The pass
responsible for register usage propagation has been made target
independent. A print method and command line option -print-regusage has
been added so that RegMaks details can be printed in Release builds also,
this enables lit test case to be testable in Release build too. Other minor
changes to adhere coding and naming conventions.
Testing:
======
test-suite has been tested with IPRA enabled.
Study and other:

I have experimented with indirect call specially which are due to use of
function pointers as shown in above example:
Following code in RegUsageInfoPropagate.cpp handles this kind of indirect
calls :
for (MachineBasicBlock &MBB : MF) {
for (MachineInstr &MI : MBB) {
if (!MI.isCall())
continue;
DEBUG(dbgs()
<< "Call Instruction Before Register Usage Info Propagation :
\n");

Dear community,
This is to brief you the progress of Interprocedural Register Allocation,
for those who are interested to see the progress in terms of code please
consider http://reviews.llvm.org/D20769
This patch contains simple infrastructure to propagate register usage
information of callee to caller in call graph. The code generation order is
changed to follow bottom up order on call graph ,
