compiler/gcc4+: Remove inaccurate comment about 'asm goto' miscompiles The bug referenced by the comment in this commit was not completely fixed in GCC 4.8.2, as I mentioned in a thread back in February: https://lkml.org/lkml/2014/2/12/797 The conclusion at that time was to make the quirk unconditional until the bug could be found and fixed in GCC. Unfortunately, when I submitted the patch (commit a9f18034) I left a comment in that claimed the bug was fixed in GCC 4.8.2+. This comment is inaccurate, and should be removed.
