Now that `--opcode-index=-1` is mostly stable, and i can migrate off of my custom tooling that emulated it, there comes a bit of confusion as to the status of the run. It is normal for the single all-opcode run to take ~3 minutes, and it's a bit more than one can be comfortable with, without having some sort of visual indication of the progress. Thus, i present: ``` $ ./bin/llvm-exegesis -mode=inverse_throughput --opcode-index=-1 --benchmarks-file=/dev/null --dump-object-to-disk=0 --measurements-print-progress --skip-measurements <...> XAM_Fp80: unsupported opcode: pseudo instruction XBEGIN: Unsupported opcode: isPseudo/usesCustomInserter XBEGIN_2: Unsupported opcode: isBranch/isIndirectBranch XBEGIN_4: Unsupported opcode: isBranch/isIndirectBranch XCH_F: unsupported second-form X87 instruction Processing... 1%, ETA 02:10 Processing... 2%, ETA 02:03 Processing... 3%, ETA 02:00 Processing... 4%, ETA 01:57 Processing... 5%, ETA 01:54 Processing... 6%, ETA 01:53 Processing... 7%, ETA 01:51 Processing... 8%, ETA 01:50 Processing... 9%, ETA 01:49 Processing... 10%, ETA 01:48 Processing... 11%, ETA 01:46 Processing... 12%, ETA 01:45 Processing... 13%, ETA 01:44 Processing... 14%, ETA 01:43 Processing... 15%, ETA 01:42 Processing... 16%, ETA 01:42 Processing... 17%, ETA 01:41 ``` As usual, the ETA estimation is statically-insignificant, and is a lie/does not converge at least until 50% through. It would be nice to have an actual progress indicator like in LIT, but i'm not sure we have such a luxury in C++ form in LLVM codebase already.
