bolt-tests

This is a testsuite containing large binaries for BOLT.

Usage

Prerequisites

• Install binary tests prerequisites:

sudo apt-get install libtinfo5 zstd

• Install perf tools:

sudo apt-get install linux-tools-`uname -r`

LLVM CMake configuration

Configure LLVM with the LLVM_EXTERNAL_PROJECTS and LLVM_EXTERNAL_PROJECTS_SOURCE_DIR cmake flags. Example:

$ git clone https://github.com/llvm/llvm-project
$ git clone https://github.com/rafaelauler/bolt-tests
$ cmake -B bolt-build -G Ninja llvm-project/llvm \
   -DCMAKE_BUILD_TYPE=Release \
   -DLLVM_TARGETS_TO_BUILD="X86;AArch64" \
   -DLLVM_ENABLE_PROJECTS="clang;lld;bolt" \
   -DLLVM_EXTERNAL_PROJECTS="bolttests" \
   -DLLVM_EXTERNAL_BOLTTESTS_SOURCE_DIR=$(pwd)/bolt-tests
$ cmake --build bolt-build --target check-large-bolt

When this repo is configured as an external project, it will add itself as an extra target in LLVM named "check-large-bolt". Just build that target to run this testsuite.
