Hi, I'm trying to align long long variable on a 4 byte boundary. I tried to change to clang frontend as follow: LongLongAlign = 32 ; LongLongWidth = 64; The asm output is still 8 bytes, when I declare a long long global array: .align 8 How can I change the alignment from 8 byte to 4 byte for long long variables? Do I need to write an ASMprinter class or change something in my backend?

...if you could verify that this works for you as well. To actually solve this properly I see two main options: (1) we could specialize PointerLikeTypeTraits for User*, and leave the default value of NumLowBitsAvailable at 3. (2) we could drop the default NumLowBitsAvailable to 2 (or even use _alignof and similar compiler-specific extensions to determine it), and allow classes that assert that they are only ever allocated through malloc to relax it back up to 3. My preference would be for option (2), due to the difficulty of tracking this bug down, and the risk of future similar bugs happ...

Hi all, I've located a regression that causes my project to crash. It's in revision 67979, where PointerIntPair is changed from storing the integer in the upper bits instead of the lower bits. My project is an experimental JIT-compiler in Windows. So I was wondering if anyone had any clue why the new PointerIntPair implementation might fail. It doesn't seem very safe to me to
