OK, forcing BLKmode on TypeDArray has reproduced it. Looks like is just a case of not removing side effects of the left and right operands. -- You are receiving this mail because: You are watching all bug changes. |

http://bugzilla.gdcproject.org/show_bug.cgi?id=223 --- Comment #6 from Iain Buclaw <ibuclaw@gdcproject.org> --- Caused by the exact same symptom though. Somewhere in ExprVisitor(EqualExp) there needs to be a call to maybe_make_temp. -- You are receiving this mail because: You are watching all bug changes. |

http://bugzilla.gdcproject.org/show_bug.cgi?id=223 --- Comment #7 from Johannes Pfau <johannespfau@gmail.com> --- Adding maybe_make_temp calls to https://github.com/D-Programming-GDC/GDC/blob/master/gcc/d/expr.cc#L266 solves this issue. But I'm wondering: I guess we have to add maybe_make_temp for everything which could end up in a call to memcpy? So: https://github.com/D-Programming-GDC/GDC/blob/master/gcc/d/expr.cc#L279 Probably not necessary? https://github.com/D-Programming-GDC/GDC/blob/master/gcc/d/expr.cc#L292 https://github.com/D-Programming-GDC/GDC/blob/master/gcc/d/expr.cc#L127 https://github.com/D-Programming-GDC/GDC/blob/master/gcc/d/expr.cc#L139 https://github.com/D-Programming-GDC/GDC/blob/master/gcc/d/expr.cc#L150 -- You are receiving this mail because: You are watching all bug changes. |

http://bugzilla.gdcproject.org/show_bug.cgi?id=223 --- Comment #8 from Iain Buclaw <ibuclaw@gdcproject.org> --- I'd just make the changes on a per-case basis, but I would have thought it it would just affect RECORD_TYPEs. Testing each permutation shouldn't be too difficult. eg: float test1() { return float ... } delegate test2() { return delegate ... } test1() == test1(); test2() == test2(); -- You are receiving this mail because: You are watching all bug changes. |
