Usage: $0 [BASE_SHA] [PEAK_SHA] [BUILD_TARGETS]

Build ISPC benchmarks for performance comparison between two commits.

ARGUMENTS:
  BASE_SHA        Base commit SHA for comparison (default: HEAD^)
  PEAK_SHA        Peak commit SHA for comparison (default: HEAD)
  BUILD_TARGETS   Space-separated list of ISPC targets (default: all AVX-512 targets)

DEFAULT TARGETS:
  $DEFAULT_TARGETS

EXAMPLES:
  $0                                  # Compare HEAD^ vs HEAD with default targets
  $0 abc123 def456                    # Compare specific commits with default targets
  $0 HEAD~5 HEAD "avx2-i32x8 avx512skx-x16"  # Compare commits with custom targets

The script will:
1. Check out PEAK_SHA and build benchmarks for each target
2. Check out BASE_SHA and build benchmarks for each target
3. Create separate build directories for each target/version combination

Build directories will be named: {target}-peak and {target}-base
