From: Steven Noonan Date: Sat, 25 Oct 2014 22:09:42 +0000 (-0700) Subject: compiler/gcc4+: Remove inaccurate comment about 'asm goto' miscompiles X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5631b8fba640a4ab2f8a954f63a603fa34eda96b;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git 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.
