  "message": "Restore the simple loop in fastfloat_strncasecmp\n\nPR #356 replaced the 3/5-character case-insensitive compare used by\nparse_infnan with SWAR helpers (fastfloat_strncasecmp3/5 plus a generic\nmemcpy-based fastfloat_strncasecmp). That code only runs for \"nan\",\n\"inf\" and \"infinity\" inputs, so it cannot help ordinary parsing, but it\ngrew the inlined inf/nan tail of the parser: on x86-64 (GCC 14 and\nclang 21) the per-commit benchmarks dropped by 1.5-2.5% because the\nextra dead code changed inlining decisions and register allocation on\nthe hot path (+7 instructions/float on canada.txt).\n\nGo back to the plain loop, which the compiler unrolls for the constant\nlengths 3 and 5, and drop the now-unused generic SWAR function. The\n`actual \u003c 256` guard of the original is unnecessary: OR-ing 0x20 into\na value can only equal an ASCII lowercase letter when the value is that\nletter or its uppercase form, so the plain OR is exact for every\ncharacter type.\n",
