Any\npath directly leading to a call of this function will be unlikely. And gcc\nwill try to generate smaller code for the function itself.\n\nPlease use with care. The code generation advantage isn\u0027t large and in most\ncases it is not worth uglifying code with this.\n\nThis patch marks some common error functions like panic(), printk()\nas cold. This will longer term make many unlikely()s unnecessary, although\nwe can keep them for now for older compilers.\n\nBUG is not marked cold because there is currently no way to tell\ngcc to mark a inline function told.\n\nAlso all __init and __exit functions are marked cold. With a non -Os\nbuild this will tell the compiler to generate slightly smaller code\nfor them. I think it currently only uses less alignments for labels,\nbut that might change in the future.\n\nOne disadvantage over *likely() is that they cannot be easily instrumented\nto verify them.\n\nAnother drawback is that only the latest gcc 4.3 snapshots support this.\nUnfortunately we cannot detect this using the preprocessor. This means older\nsnapshots will fail now. I don\u0027t think that\u0027s a problem because they are\nunreleased compilers that nobody should be using.\n\ngcc also has a __hot__ attribute, but I don\u0027t see any sense in using\nthis in the kernel right now. But someday I hope gcc will be able\nto use more aggressive optimizing for hot functions even in -Os,\nif that happens it should be added.\n\nIncludes compile fix from Thomas Gleixner.\n\nCc: Jan Hubicka \u003cjh@suse.cz\u003e\nSigned-off-by: Andi Kleen \u003cak@suse.de\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "21124a82bb82e100369846ff2044dd5ea65fc934", "tree": "24375f6b94a644e970aaac1e1a7f6cea1efe20ce", "parents": [ "6c977aad03a18019015035958c65b6729cd0574c" ], "author": { "name": "Andi Kleen", "email": "ak@suse.de", "time": "Mon May 21 14:31:46 2007 +0200" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Mon May 21 09:56:57 2007 -0700" }, "message": "x86_64: Support gcc 5 properly\n\nThe ifdef tests were broken.
