+Tests for sample profiles encoded in GCC's gcov format.
+
+1- Show all functions. This profile has a single main() function with several
+ inlined callees.
+RUN: llvm-profdata show --sample %p/Inputs/gcc-sample-profile.gcov | FileCheck %s --check-prefix=SHOW1
+SHOW1: Function: main: 364084, 0, 6 sampled lines
+SHOW1: line offset: 2, discriminator: 3, inlined callee: _Z3fool: 243786, 0, 3 sampled lines
+SHOW1: line offset: 1, discriminator: 3, inlined callee: _Z3bari: 0, 0, 2 sampled lines
+SHOW1: line offset: 1, discriminator: 8, inlined callee: _Z3bari: 0, 0, 2 sampled lines
+SHOW1: line offset: 1, discriminator: 7, inlined callee: _Z3bari: 98558, 0, 2 sampled lines
+
+2- Convert the profile to text encoding and check that they are both
+ identical.
+RUN: llvm-profdata merge --sample %p/Inputs/gcc-sample-profile.gcov --text -o - | llvm-profdata show --sample - -o %t-text
+RUN: llvm-profdata show --sample %p/Inputs/gcc-sample-profile.gcov -o %t-gcov
+RUN: diff %t-text %t-gcov
+
+4- Merge the gcov and text encodings of the profile and check that the
+ counters have doubled.
+RUN: llvm-profdata merge --sample --text %p/Inputs/gcc-sample-profile.gcov -o %t-gcov
+RUN: llvm-profdata merge --sample --text %p/Inputs/gcc-sample-profile.gcov %t-gcov -o - | FileCheck %s --check-prefix=MERGE1
