Basic tests for sample profiles using fs discriminators.
1- Show command and keep all the discrimiantor bits
RUN: llvm-profdata show --sample %p/Inputs/sample-fs.proftext -profile-isfs | FileCheck %s --check-prefix=SHOW1
RUN: llvm-profdata show --sample %p/Inputs/sample-fs.proftext -profile-isfs -fs-discriminator-pass=PassLast | FileCheck %s --check-prefix=SHOW1
SHOW1: Function: main: 6436, 0, 6 sampled lines
SHOW1: Samples collected in the function's body {
SHOW1: 4: 534
SHOW1: 4.2: 534
SHOW1: 4.738209026: 1068
SHOW1: 5: 1075
SHOW1: 5.1: 1075
SHOW1: 5.738209025: 2150
SHOW1: }
2- Show command and keep only the base discriminator bits
RUN: llvm-profdata show --sample %p/Inputs/sample-fs.proftext -profile-isfs -fs-discriminator-pass=Base | FileCheck %s --check-prefix=SHOW2
SHOW2: Function: main: 6436, 0, 4 sampled lines
SHOW2: Samples collected in the function's body {
SHOW2: 4: 534
SHOW2: 4.2: 1602
SHOW2: 5: 1075
SHOW2: 5.1: 3225
SHOW2: }
3- Show command and keep only the base discriminator bits and first pass of FS discriminator
RUN: llvm-profdata show --sample %p/Inputs/sample-fs.proftext -profile-isfs -fs-discriminator-pass=Pass1 | FileCheck %s --check-prefix=SHOW3
Function: main: 6436, 0, 6 sampled lines
SHOW3: Samples collected in the function's body {
SHOW3: 4: 534
SHOW3: 4.2: 534
SHOW3: 4.11522: 1068
SHOW3: 5: 1075
SHOW3: 5.1: 1075
SHOW3: 5.11521: 2150
SHOW3: }
4- Merge command and keep all the discrimiantor bits
RUN: llvm-profdata merge --sample %p/Inputs/sample-fs.proftext -profile-isfs -fs-discriminator-pass=PassLast --binary -o - | llvm-profdata show --sample - -o %t1-binary_1
RUN: llvm-profdata merge --sample %p/Inputs/sample-fs.proftext -profile-isfs --binary -o - | llvm-profdata show --sample - -o %t1-binary_2
RUN: llvm-profdata show --sample %p/Inputs/sample-fs.proftext -profile-isfs -o %t1-text
RUN: diff %t1-binary_1 %t1-text
RUN: diff %t1-binary_2 %t1-text
2- Merge command and keep only the base discriminator bits
RUN: llvm-profdata merge --sample %p/Inputs/sample-fs.proftext -profile-isfs -fs-discriminator-pass=Base --binary -o - | llvm-profdata show --sample - -o %t2-binary
RUN: llvm-profdata show --sample %p/Inputs/sample-fs.proftext -profile-isfs -fs-discriminator-pass=Base -o %t2-text
RUN: diff %t2-binary %t2-text
3- Merge command and keep only the base discriminator bits and first pass of FS discriminator
RUN: llvm-profdata merge --sample %p/Inputs/sample-fs.proftext -profile-isfs -fs-discriminator-pass=Pass1 --binary -o - | llvm-profdata show --sample - -o %t3-binary
RUN: llvm-profdata show --sample %p/Inputs/sample-fs.proftext -profile-isfs -fs-discriminator-pass=Pass1 -o %t3-text
RUN: diff %t3-binary %t3-text
4- ProfileIsFS is set properly in extbinary format from the internal option
RUN: llvm-profdata merge --sample %p/Inputs/sample-fs.proftext -profile-isfs --extbinary -o %t_extbin.afdo
RUN: llvm-profdata show --sample --show-sec-info-only %t_extbin.afdo | FileCheck %s --check-prefix=ISFSSET
ISFSSET: Flags: {fs-discriminator}
