I will do that, but just to note this will add method to MO so this change is not completely contained in IPRA files.

...ass that iterates through each registers and check if it is used or not and based on that details create a RegMask and a target specific machine function pass that uses the RegMask created by second pass and propagates information by updating call instructions RegMask. To update the RegMask of MI , setRegMask() function has been added to MachineOperand, a command line option -enable-ipra and debug type -debug-only=“ipra" has been added to control the optimization through llc. Testing: ===== The above mentioned implementation has been tested over SNU-Real-Time benchmark suit (http://www.cprover.org...
