Rollup merge of #139636 - Zoxc:graph-edges-len-u32, r=compiler-errors
Encode dep node edge count as u32 instead of usize This encodes the dep node edge count as u32 instead of usize. It doesn't need to be usize as the count is limited the the unique number of dep nodes which we use a 32-bit index for. It probably saves some branches for encoding / decoding, but it isn't too hot as the count gets packed in with other fields when it's low. <table><tr><td rowspan="2">Benchmark</td><td colspan="1"><b>Before</b></th><td colspan="2"><b>After</b></th><td colspan="1"><b>Before</b></th><td colspan="2"><b>After</b></th><td colspan="1"><b>Before</b></th><td colspan="2"><b>After</b></th></tr><tr><td align="right">Time</td><td align="right">Time</td><td align="right">%</th><td align="right">Physical Memory</td><td align="right">Physical Memory</td><td align="right">%</th><td align="right">Committed Memory</td><td align="right">Committed Memory</td><td align="right">%</th></tr><tr><td>🟣 <b>clap</b>:check:unchanged</td><td align="right">0.3343s</td><td align="right">0.3343s</td><td align="right"> -0.00%</td><td align="right">97.02 MiB</td><td align="right">96.89 MiB</td><td align="right"> -0.13%</td><td align="right">167.93 MiB</td><td align="right">167.80 MiB</td><td align="right"> -0.08%</td></tr><tr><td>🟣 <b>hyper</b>:check:unchanged</td><td align="right">0.1353s</td><td align="right">0.1350s</td><td align="right"> -0.19%</td><td align="right">61.91 MiB</td><td align="right">61.83 MiB</td><td align="right"> -0.13%</td><td align="right">124.64 MiB</td><td align="right">124.64 MiB</td><td align="right"> 0.00%</td></tr><tr><td>🟣 <b>regex</b>:check:unchanged</td><td align="right">0.2479s</td><td align="right">0.2481s</td><td align="right"> 0.10%</td><td align="right">78.34 MiB</td><td align="right">78.35 MiB</td><td align="right"> 0.02%</td><td align="right">145.20 MiB</td><td align="right">145.31 MiB</td><td align="right"> 0.08%</td></tr><tr><td>🟣 <b>syn</b>:check:unchanged</td><td align="right">0.5347s</td><td align="right">0.5333s</td><td align="right"> -0.26%</td><td align="right">118.63 MiB</td><td align="right">118.66 MiB</td><td align="right"> 0.02%</td><td align="right">193.05 MiB</td><td align="right">193.11 MiB</td><td align="right"> 0.03%</td></tr><tr><td>Total</td><td align="right">1.2521s</td><td align="right">1.2507s</td><td align="right"> -0.11%</td><td align="right">355.90 MiB</td><td align="right">355.74 MiB</td><td align="right"> -0.05%</td><td align="right">630.83 MiB</td><td align="right">630.87 MiB</td><td align="right"> 0.01%</td></tr><tr><td>Summary</td><td align="right">1.0000s</td><td align="right">0.9991s</td><td align="right"> -0.09%</td><td align="right">1 byte</td><td align="right">1.00 bytes</td><td align="right"> -0.06%</td><td align="right">1 byte</td><td align="right">1.00 bytes</td><td align="right"> 0.01%</td></tr></table>
