Clone functions that are shared between the Main thread and Interrupt thread. CallSites are changed in AsmPrinter currently. A better solution would have been to modify the legalizer (SoftenFloat) to allow targets to change the name of libcalls for float operations. But that currently breaks other targets. Also, cloing of automatic variables is done AsmPrinter, a better approach would be to use the ValueMap in CloneFunction itself. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79562 91177308-0d34-0410-b5e6-96231b3b80d8
