To update the inputs used below, run
Inputs/update_vtable_value_prof_inputs.sh /path/to/updated/clang++
; Raw profiles stores zlib-compressed vtable names. Raw profile reader needs
; to decompress them.
; REQUIRES: zlib
; RUN: rm -rf %t && mkdir %t && cd %t
Show profile data from raw profiles.
RUN: llvm-profdata show --function=main --ic-targets --show-vtables %p/Inputs/vtable-value-prof-basic.profraw | FileCheck %s --check-prefix=RAW
Generate indexed profile from raw profile and show the data.
RUN: llvm-profdata merge %p/Inputs/vtable-value-prof-basic.profraw -o indexed.profdata
RUN: llvm-profdata show --function=main --ic-targets --show-vtables indexed.profdata | FileCheck %s --check-prefix=INDEXED
Generate text profile from raw profile and show the data.
RUN: llvm-profdata merge --text %p/Inputs/vtable-value-prof-basic.profraw -o vtable-value-prof-basic.proftext
RUN: llvm-profdata show --function=main --ic-targets --show-vtables --text vtable-value-prof-basic.proftext | FileCheck %s --check-prefix=ICTEXT
