Re: [Qemu-devel] [PATCH 1/1] tci: eliminate UB due to unaligned reads

My patch is kind of trivial quick fix that just eliminates these unaligned reads and doesn't seem to require complicated testing supposing my code properly handles integer promotion (and hope it will not slow the interpreter down). Aligning everything, on the other hand, can not only remove the

[Qemu-devel] [PATCH 0/1] Fix unaligned reads in the tcg/tci.c

The code in tcg/tci.c reads some data from TCI bytecode through pointer dereferencing. As far as I know unaligned reads in such a way are undefined behavior and compiling with -fsanitize=undefined enumerated them as such at run-time. I have replaced such reads with invocations of ld{l,q}_he_p. A
