Tests for conversion between text and binary encoded sample profiles.
1- Encode the original profile into binary form. All the tests below will use
the binary profile.
RUN: llvm-profdata merge --sample %p/Inputs/inline-samples.afdo -o %t.profbin
2- Show all functions. This profile has a single main() function with several
inlined callees.
RUN: llvm-profdata show --sample %t.profbin | FileCheck %s --check-prefix=SHOW1
SHOW1: Function: main: 366846, 0, 6 sampled lines
SHOW1: line offset: 2, discriminator: 3, inlined callee: _Z3fool: 246044, 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: 99492, 0, 2 sampled lines
SHOW1: line offset: 1, discriminator: 2, number of samples: 46732
3- Convert the binary profile to text encoding and check that they are both
identical.
RUN: llvm-profdata merge --sample %t.profbin --text -o - | llvm-profdata show --sample - -o %t-bintext
RUN: llvm-profdata show --sample %p/Inputs/inline-samples.afdo -o %t-text
RUN: diff %t-bintext %t-text
4- Merge the binary and text encodings of the profile and check that the
counters have doubled.
RUN: llvm-profdata merge --sample --text %t.profbin %p/Inputs/inline-samples.afdo -o - | FileCheck %s --check-prefix=MERGE1
