[llvm-opt-report] Distinguish inlined contexts when optimizations differ How code is optimized sometimes, perhaps often, depends on the context into which it was inlined. This change allows llvm-opt-report to track the differences between the optimizations performed, or not, in different contexts, and when these differ, display those differences. For example, this code: $ cat /tmp/q.cpp void bar(); void foo(int n) { for (int i = 0; i < n; ++i) bar(); } void quack() { foo(4); } void quack2() { foo(4); } will now produce this report: < /home/hfinkel/src/llvm/test/tools/llvm-opt-report/Inputs/q.cpp 2 | void bar(); 3 | void foo(int n) { [[ > foo(int): 4 | for (int i = 0; i < n; ++i) > quack(), quack2(): 4 U4 | for (int i = 0; i < n; ++i) ]] 5 | bar(); 6 | } 7 | 8 | void quack() { 9 I | foo(4); 10 | } 11 | 12 | void quack2() { 13 I | foo(4); 14 | } 15 | Note that the tool has demangled the function names, and grouped the reports associated with line 4. This shows that the loop on line 4 was unrolled by a factor of 4 when inlined into the functions quack() and quack2(), but not in the function foo(int) itself. llvm-svn: 283402
