Basic test for option -showcs:
RUN: llvm-profdata show %p/Inputs/cs.proftext | FileCheck  %s -check-prefix=ZEROSUMMARY
RUN: llvm-profdata show %p/Inputs/noncs.proftext | FileCheck  %s -check-prefix=SUMMARY
RUN: llvm-profdata show -showcs %p/Inputs/cs.proftext | FileCheck  %s -check-prefix=SUMMARY
RUN: llvm-profdata show -showcs %p/Inputs/noncs.proftext | FileCheck  %s -check-prefix=ZEROSUMMARY
ZEROSUMMARY: Instrumentation level: IR
ZEROSUMMARY: Total functions: 0

Basic tests for context sensitive profile dump functions:
RUN: llvm-profdata merge -o %t-combined.profdata %p/Inputs/cs.proftext %p/Inputs/noncs.proftext

RUN: llvm-profdata show --all-functions -counts -showcs %p/Inputs/cs.proftext > %t-text.csdump
RUN: llvm-profdata show --all-functions -counts -showcs %t-combined.profdata > %t-index.csdump
RUN: diff %t-text.csdump %t-index.csdump

RUN: llvm-profdata show --all-functions -counts %p/Inputs/noncs.proftext > %t-text.noncsdump
RUN: llvm-profdata show --all-functions -counts %t-combined.profdata > %t-index.noncsdump
RUN: diff %t-text.noncsdump %t-index.noncsdump

Roundtrip test:

RUN: llvm-profdata merge -o %t.0.profdata %S/Inputs/CSIR_profile.proftext
RUN: llvm-profdata merge -text -o %t.0.proftext %t.0.profdata
RUN: diff -b %t.0.proftext %S/Inputs/CSIR_profile.proftext
