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: Function: main: 184019, 0, 7 sampled lines
SHOW1: line offset: 9, discriminator: 0, number of samples: 2064, calls: _Z3fooi:631 _Z3bari:1471
SHOW1: Function: _Z3fooi: 7711, 610, 1 sampled lines
SHOW1: Function: _Z3bari: 20301, 1437, 1 sampled lines
SHOW1: line offset: 1, discriminator: 0, number of samples: 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: line offset: 1, discriminator: 0, number of samples: 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
