  "message": "convert \"oidcmp() \u003d\u003d 0\" to oideq()\n\nUsing the more restrictive oideq() should, in the long run,\ngive the compiler more opportunities to optimize these\ncallsites. For now, this conversion should be a complete\nnoop with respect to the generated code.\n\nThe result is also perhaps a little more readable, as it\navoids the \"zero is equal\" idiom. Since it\u0027s so prevalent in\nC, I think seasoned programmers tend not to even notice it\nanymore, but it can sometimes make for awkward double\nnegations (e.g., we can drop a few !!oidcmp() instances\nhere).\n\nThis patch was generated almost entirely by the included\ncoccinelle patch. This mechanical conversion should be\ncompletely safe, because we check explicitly for cases where\noidcmp() is compared to 0, which is what oideq() is doing\nunder the hood. Note that we don\u0027t have to catch \"!oidcmp()\"\nseparately; coccinelle\u0027s standard isomorphisms make sure the\ntwo are treated equivalently.\n\nI say \"almost\" because I did hand-edit the coccinelle output\nto fix up a few style violations (it mostly keeps the\noriginal formatting, but sometimes unwraps long lines).\n\nSigned-off-by: Jeff King \u003cpeff@peff.net\u003e\nSigned-off-by: Junio C Hamano \u003cgitster@pobox.com\u003e\n",
