The SampleProfWriter emits function information in an order determined by the string hash function. The situation is a bit brittle, because changing the hash function can break the tests. Instead of sorting the function samples to get a relaible ordering (that might be too expensive), make the tests not depend on a particular ordering of function samples.

Tests for weighted merge of sample profiles.

1- Merge the foo and bar profiles with unity weight and verify the combined output
|
|
RUN: llvm-profdata merge -sample -text -weighted-input=1,%p/Inputs/weight-sample-bar.proftext -weighted-input=1,%p/Inputs/weight-sample-foo.proftext -o - | FileCheck %s -check-prefix=1X_1X_WEIGHT
|

RUN: llvm-profdata merge -sample -text -weighted-input=1,%p/Inputs/weight-sample-bar.proftext %p/Inputs/weight-sample-foo.proftext -o - | FileCheck %s -check-prefix=1X_1X_WEIGHT

2- Merge the foo and bar profiles with weight 3x and 5x respectively and verify the combined output

3- Bad merge: invalid weight
|
|
RUN: not llvm-profdata merge -sample -weighted-input=3,%p/Inputs/weight-sample-bar.proftext -weighted-input=0,%p/Inputs/weight-sample-foo.proftext -o %t.out 2>&1 | FileCheck %s -check-prefix=INVALID_WEIGHT
|
|
RUN: not llvm-profdata merge -sample -weighted-input=3,%p/Inputs/weight-sample-bar.proftext -weighted-input=0.75,%p/Inputs/weight-sample-foo.proftext -o %t.out 2>&1 | FileCheck %s -check-prefix=INVALID_WEIGHT
|
|
RUN: not llvm-profdata merge -sample -weighted-input=3,%p/Inputs/weight-sample-bar.proftext -weighted-input=-5,%p/Inputs/weight-sample-foo.proftext -o %t.out 2>&1 | FileCheck %s -check-prefix=INVALID_WEIGHT
|
|
RUN: not llvm-profdata merge -sample -weighted-input=3,%p/Inputs/weight-sample-bar.proftext -weighted-input=,%p/Inputs/weight-sample-foo.proftext -o %t.out 2>&1 | FileCheck %s -check-prefix=INVALID_WEIGHT
|
|
RUN: not llvm-profdata merge -sample -weighted-input=3,%p/Inputs/weight-sample-bar.proftext -weighted-input=%p/Inputs/weight-sample-foo.proftext -o %t.out 2>&1 | FileCheck %s -check-prefix=INVALID_WEIGHT
|
|
INVALID_WEIGHT: error: Input weight must be a positive integer.
|
|
|
|
4- Bad merge: input path does not exist
|
|
RUN: not llvm-profdata merge -sample -weighted-input=3,%p/Inputs/does-not-exist.proftext -weighted-input=2,%p/Inputs/does-not-exist-either.proftext -o %t.out 2>&1 | FileCheck %s -check-prefix=INVALID_INPUT
|
|
INVALID_INPUT: {{.*}}: {{.*}}does-not-exist.proftext: {{[Nn]}}o such file or directory
|
|
|
|
5- No inputs
|
|
RUN: not llvm-profdata merge -sample -o %t.out 2>&1 | FileCheck %s -check-prefix=NO_INPUT
|
|
NO_INPUT: {{.*}}: No input files specified. See llvm-profdata{{(\.EXE|\.exe)?}} merge -help
