With this patch we can now read and write inline stacks in sample profiles to the binary encoded profiles. In a subsequent patch, I will add a string table to the binary encoding. Right now function names are emitted as strings every time we find them. This is too bloated and will produce large files in applications with lots of inlining. llvm-svn: 249861

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
