------- Comment #1 from jakub at gcc dot gnu dot org 2010-09-15 14:10 ------- No longer crashes in 4.5/4.6 since r147980, aka SRA rewrite. The only difference in *.optimized is though that before r147980 we have: m3.3_3 = VIEW_CONVERT_EXPR<v4sf>(m2); m3.5_4 = m3.3_3 * { 5.0e+0, 1.5e+1, 2.5e+1, 3.5e+1 }; m4$0_5 = VIEW_CONVERT_EXPR<float[4]>(m3.5_4)[0]; if (m4$0_5 != 2.0e+1) and after it: m3.3_7 = VIEW_CONVERT_EXPR<v4sf>(m2); m3.5_8 = m3.3_7 * { 5.0e+0, 1.5e+1, 2.5e+1, 3.5e+1 }; m4 = VIEW_CONVERT_EXPR<float[4]>(m3.5_8); m4$0_22 = m4[0]; if (m4$0_22 != 2.0e+1) where m2 (and in the second case m4 as well) are float [4] arrays, m3 is v4sf and m4$0 is float. This doesn't look like a fix for the case that the VCE<v4sf>(m2) load during expansion assumes m2 is 128-bits aligned when it is not.
