1""" 2This test produces three shared libraries: 3 41. libt-instr.so is instrumented 52. libt-no-instr1.so is not instrumented 63. libt-no-instr2.so is built with profile rt linked in (via -u<hook>), but the object file is built 7 with instrumentation turned off. 8 9After the libraries are built, the main program is then built with/without instrumentation and linked 10against 3 libraries above. 11 12The test is to verify that programs linked against these shared objects with and without instrumentation 13enabled behave as expected. 14""" 15 16RUN: mkdir -p %t.d 17RUN: %clang_profgen -o
