...ttp://llvm.org/bugs/show_bug.cgi?id=10841 I was looking at this again today. What about the following approach: (1) Change AllocaInst to compute the isStaticAlloca once and remember it. (2) Check all functions for (a) static allocations with an alignment larger than the default stack alignemnt (b) dynamic alloca (3) If (a) is present and not (b), use the frame pointer to address arguments and the stack pointer to address local variables. If (b) is present and not (a), use the frame pointer to address arguments and local variables. Realign the stack pointer to the larg...

Even if you explicitly specify –stack-alignment=16 the aligned movs are still generated. It is not an issue related to ABI. See my original mail: ./llc -mattr=+avx -stack-alignment=16 < basic.ll | grep movaps | grep ymm | grep rbp vmovaps -176(%rbp), %ymm14 vmovaps -144(%rbp), %ymm11 vmovaps -240(%rbp), %ymm13 - Elena From: Cameron McInally

This series is based on latest linux-next. The patches are located at: https://github.com/davidhildenbrand/linux.git virtio-mem-rfc-v4 The basic idea of virtio-mem is to provide a flexible, cross-architecture memory hot(un)plug solution that avoids many limitations imposed by existing technologies, architectures, and interfaces. More details can be found below and in linked material. This

Long time no RFC! I finally had time to get the next version of the Linux driver side of virtio-mem into shape, incorporating ideas and feedback from previous discussions. This RFC is based on the series currently on the mm list: - [PATCH 0/3] Remove __online_page_set_limits() - [PATCH v1 0/3] mm/memory_hotplug: Export generic_online_page() - [PATCH v4 0/8] mm/memory_hotplug: Shrink zones before
