# HAKMEM Phase 7 + Pool TLS Phase 1.5b — Build & Run Cheatsheet
|
||
|
||
This document captures the stable build/run recipe used for recent benches.
|
||
|
||
## One‑liner Build (recommended)
|
||
|
||
```
|
||
./build.sh <target>
|
||
|
||
# examples
|
||
./build.sh bench_mid_large_mt_hakmem
|
||
./build.sh bench_random_mixed_hakmem
|
||
./build.sh larson_hakmem
|
||
```
|
||
|
||
Enables at build time:
|
||
- POOL_TLS_PHASE1=1 (Pool TLS Phase 1.5b)
|
||
- HEADER_CLASSIDX=1 (Phase 7 header)
|
||
- AGGRESSIVE_INLINE=1
|
||
- PREWARM_TLS=1
|
||
|
||
Verify switches:
|
||
```
|
||
make print-flags
|
||
```
|
||
|
||
Optional safety/verbosity toggles:
|
||
- `HAKMEM_TINY_SAFE_FREE=1` — strict free validation (mincore on all frees). Slower but safest.
|
||
- `HAKMEM_DEBUG_VERBOSE=1` — enable verbose logs for Tiny header/free, etc.
|
||
|
||
Examples:
|
||
```
|
||
make clean && make HAKMEM_TINY_SAFE_FREE=1 POOL_TLS_PHASE1=1 HEADER_CLASSIDX=1 AGGRESSIVE_INLINE=1 PREWARM_TLS=1 bench_mid_large_mt_hakmem
|
||
```
|
||
|
||
## Bench Recipes (used in reports)
|
||
|
||
Larson (Mixed)
|
||
```
|
||
./build.sh larson_hakmem
|
||
make larson_system
|
||
./larson_hakmem 2 8 128 1024 1 12345 1
|
||
./larson_hakmem 2 8 128 1024 1 12345 4
|
||
./larson_system 2 8 128 1024 1 12345 1
|
||
./larson_system 2 8 128 1024 1 12345 4
|
||
```
|
||
|
||
Pool TLS (8–52KB)
|
||
```
|
||
./build.sh bench_pool_tls_hakmem
|
||
make bench_pool_tls_system
|
||
./bench_pool_tls_hakmem 1 100000 256 42
|
||
./bench_pool_tls_hakmem 4 50000 256 42
|
||
./bench_pool_tls_system 1 100000 256 42
|
||
./bench_pool_tls_system 4 50000 256 42
|
||
```
|
||
|
||
Random Mixed (Tiny 128–1024B)
|
||
```
|
||
./build.sh bench_random_mixed_hakmem
|
||
make bench_random_mixed_system
|
||
for s in 128 256 512 1024; do \
|
||
./bench_random_mixed_hakmem 100000 $s 42; \
|
||
./bench_random_mixed_system 100000 $s 42; \
|
||
done
|
||
```
|
||
|
||
Mid‑Large MT (8–32KB)
|
||
```
|
||
./build.sh bench_mid_large_mt_hakmem
|
||
make bench_mid_large_mt_system
|
||
./bench_mid_large_mt_hakmem 1 100000 256 42
|
||
./bench_mid_large_mt_hakmem 4 50000 256 42
|
||
./bench_mid_large_mt_system 1 100000 256 42
|
||
./bench_mid_large_mt_system 4 50000 256 42
|
||
```
|
||
|
||
## Mimalloc note (when comparing)
|
||
|
||
Direct‑link mimalloc benches require runtime path:
|
||
```
|
||
export LD_LIBRARY_PATH=$PWD/mimalloc-bench/extern/mi/out/release
|
||
```
|
||
|
||
## Build hygiene
|
||
|
||
- Always prefer `./build.sh` over ad‑hoc `make` (prevents flag drift)
|
||
- Check switches: `make print-flags`
|
||
- Verify freshness: `./verify_build.sh <binary>`
