Martin Liška <marxin at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |hjl.tools at gmail dot com, | |marxin at gcc dot gnu.org Known to fail| |6.2.0 --- Comment #2 from Martin Liška <marxin at gcc dot gnu.org> --- I can confirm that it fail starting with r218818. Add -malign-data={abi|compat|cachineline} Add -malign-data={abi|compat,cachineline} to control how GCC aligns variables. "compat" uses increased alignment value compatible with GCC 4.8 and earlier, "abi" uses alignment value as specified by the psABI, and "cacheline" uses increased alignment value to match the cache line size. "compat" is the default.
