[LLVMdev] llvm-prof: Error opening 'llvmprof.out': Illegal seek
...while the llvmprof.out has not been
generated.
Below, the sequence of instructions that worked with me
$ clang -03 -emit-llvm hello.c -c -o hello.bc
$ opt -insert-edge-profiling hello.bc -o hello.profile.bc
$ llc hello.profile.bc -o hello.profile.s
$ clang -o hello.profile hello.profile.s
<LLVM_HOME_DIR>/build/Debug+Asserts/lib/libprofile_rt.so
$ ./hello.profile
$ llvm-prof hello.profile.bc
and the output is:
===-------------------------------------------------------------------------===
LLVM profiling output for execution:
