| Basic tests for sample profiles. |
| |
| 1- Show all functions |
| RUN: llvm-profdata show --sample %p/Inputs/sample-profile.proftext | FileCheck %s --check-prefix=SHOW1 |
| SHOW1-DAG: Function: main: 184019, 0, 7 sampled lines |
| SHOW1-DAG: 9: 2064, calls: _Z3bari:1471 _Z3fooi:631 |
| SHOW1-DAG: Function: _Z3fooi: 7711, 610, 1 sampled lines |
| SHOW1-DAG: Function: _Z3bari: 20301, 1437, 1 sampled lines |
| SHOW1-DAG: 1: 1437 |
| |
| 2- Show only bar |
| RUN: llvm-profdata show --sample --function=_Z3bari %p/Inputs/sample-profile.proftext | FileCheck %s --check-prefix=SHOW2 |
| SHOW2: Function: _Z3bari: 20301, 1437, 1 sampled lines |
| SHOW2: 1: 1437 |
| SHOW2-NOT: Function: main: 184019, 0, 7 sampled lines |
| SHOW2-NOT: Function: _Z3fooi: 7711, 610, 1 sampled lines |
| |
| 3- Convert the profile to binary encoding and check that they are both |
| identical. |
| RUN: llvm-profdata merge --sample %p/Inputs/sample-profile.proftext --binary -o - | llvm-profdata show --sample - -o %t-binary |
| RUN: llvm-profdata show --sample %p/Inputs/sample-profile.proftext -o %t-text |
| RUN: diff %t-binary %t-text |
| |
| 4- Merge the binary and text encodings of the profile and check that the |
| counters have doubled. |
| RUN: llvm-profdata merge --sample %p/Inputs/sample-profile.proftext -o %t-binprof |
| RUN: llvm-profdata merge --sample --text %p/Inputs/sample-profile.proftext %t-binprof -o - | FileCheck %s --check-prefix=MERGE1 |
| MERGE1: main:368038:0 |
| MERGE1: 9: 4128 _Z3bari:2942 _Z3fooi:1262 |
| MERGE1: _Z3bari:40602:2874 |
| MERGE1: _Z3fooi:15422:1220 |
| |
| 5- Detect invalid text encoding (e.g. instrumentation profile text format). |
| RUN: not llvm-profdata show --sample %p/Inputs/foo3bar3-1.proftext 2>&1 | FileCheck %s --check-prefix=BADTEXT |
| BADTEXT: error: {{.+}}: Unrecognized sample profile encoding format |
