Some basic tests for supplementing instrumentation profile with sample profile.
Test all of goo's counters will be set to PseudoHot.
RUN: llvm-profdata merge \
RUN: -supplement-instr-with-sample=%p/Inputs/mix_sample.proftext \
RUN: -suppl-min-size-threshold=0 %p/Inputs/mix_instr.proftext -o %t
RUN: llvm-profdata show %t -all-functions -counts | FileCheck %s --check-prefix=MIX1
MIX1: foo:
MIX1-NEXT: Hash: 0x0000000000000007
MIX1-NEXT: Counters: 5
MIX1-NEXT: Block counts: [12, 13, 0, 0, 0]
MIX1: goo:
MIX1-NEXT: Hash: 0x0000000000000005
MIX1-NEXT: Counters: 3
MIX1-NOT: Block counts:
MIX1-SAME: <PseudoHot>
MIX1: moo:
MIX1-NEXT: Hash: 0x0000000000000009
MIX1-NEXT: Counters: 4
MIX1-NEXT: Block counts: [3000, 1000, 2000, 500]
Test when the zero counter ratio of foo is higher than zero-counter-threshold.
RUN: llvm-profdata merge \
RUN: -supplement-instr-with-sample=%p/Inputs/mix_sample.proftext \
RUN: -suppl-min-size-threshold=0 -zero-counter-threshold=0.5 \
RUN: -instr-prof-cold-threshold=30 %p/Inputs/mix_instr.proftext -o %t
RUN: llvm-profdata show %t -all-functions -counts | FileCheck %s --check-prefix=MIX2
MIX2: foo:

MIX2-NEXT: Counters: 5

MIX2-NEXT: Counters: 4
MIX2-NEXT: Block counts: [3000, 1000, 2000, 500]
Test when the zero counter ratio of foo is lower than zero-counter-threshold.
RUN: llvm-profdata merge \
RUN: -supplement-instr-with-sample=%p/Inputs/mix_sample.proftext \
RUN: -suppl-min-size-threshold=0 -zero-counter-threshold=0.7 \
RUN: -instr-prof-cold-threshold=30 %p/Inputs/mix_instr.proftext -o %t
RUN: llvm-profdata show %t -all-functions -counts | FileCheck %s --check-prefix=MIX3
MIX3: foo:
MIX3-NEXT: Hash: 0x0000000000000007
MIX3-NEXT: Counters: 5
MIX3-NEXT: Block counts: [1384, 1500, 0, 0, 0]
MIX3: goo:
MIX3-NEXT: Hash: 0x0000000000000005
MIX3-NEXT: Counters: 3
MIX3-NOT: Block counts:
MIX3-SAME: <PseudoHot>
MIX3: moo:
MIX3-NEXT: Hash: 0x0000000000000009
MIX3-NEXT: Counters: 4
MIX3-NEXT: Block counts: [3000, 1000, 2000, 500]
Test foo's profile won't be adjusted because its size is smaller
than suppl-min-size-threshold.
RUN: llvm-profdata merge \
RUN: -supplement-instr-with-sample=%p/Inputs/mix_sample.proftext \
RUN: -suppl-min-size-threshold=2 -zero-counter-threshold=0.7 \
RUN: -instr-prof-cold-threshold=30 %p/Inputs/mix_instr_small.proftext -o %t
RUN: llvm-profdata show %t -all-functions -counts | FileCheck %s --check-prefix=MIX4
MIX4: foo:
MIX4-NEXT: Hash: 0x0000000000000007
MIX4-NEXT: Counters: 1
MIX4-NEXT: Block counts: [0]
MIX4: goo:
MIX4-NEXT: Hash: 0x0000000000000005
MIX4-NEXT: Counters: 3
MIX4-NOT: Block counts:
MIX4-SAME: <PseudoHot>
MIX4: moo:
MIX4-NEXT: Hash: 0x0000000000000009
MIX4-NEXT: Counters: 1
MIX4-NEXT: Block counts: [0]
Test profile summary won't be affected by pseudo counters.
RUN: llvm-profdata merge \
RUN: -supplement-instr-with-sample=%p/Inputs/mix_sample.proftext \
RUN: -suppl-min-size-threshold=0 %p/Inputs/mix_instr.proftext -o %t
RUN: llvm-profdata show %t -detailed-summary | FileCheck %s --check-prefix=MIX5
