+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: _Z3fooi:631 _Z3bari:1471
+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-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 _Z3fooi:1262 _Z3bari:2942
+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
