The number of different access location kinds we track is relatively small (8 so far). With this patch we replace the DenseMap that mapped from index (0-7) to the access set pointer with an array of access set pointers. This reduces memory consumption. No functional change is intended. --- Single run of the Attributor module and then CGSCC pass (oldPM) for SPASS/clause.c (~10k LLVM-IR loc): Before: ``` calls to allocation functions: 472499 (215654/s) temporary memory allocations: 77794 (35506/s) peak heap memory consumption: 35.28MB peak RSS (including heaptrack overhead): 125.46MB total memory leaked: 269.04KB ``` After: ``` calls to allocation functions: 472270 (308673/s) temporary memory allocations: 77578 (50704/s) peak heap memory consumption: 32.70MB peak RSS (including heaptrack overhead): 121.78MB total memory leaked: 269.04KB ``` Difference: ``` calls to allocation functions: -229 (346/s) temporary memory allocations: -216 (326/s) peak heap memory consumption: -2.58MB peak RSS (including heaptrack overhead): 0B total memory leaked: 0B ``` ---
