Tests for weighted merge of instrumented profiles.
1- Merge the foo and bar profiles with unity weight and verify the combined output
RUN: llvm-profdata merge -instr -weighted-input=1,%p/Inputs/weight-instr-bar.profdata -weighted-input=1,%p/Inputs/weight-instr-foo.profdata -o %t
RUN: llvm-profdata show -instr -all-functions %t > %t.out1
RUN: FileCheck %s -check-prefix=1X_1X_WEIGHT --check-prefix=1X_1X_WEIGHT-1 < %t.out1

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