Hi all, I came across the following limitation in our BasicAliasAnalysis. This happens with the following IR pattern: %x = phi [ %incptr, ... ] [ %var, ... ] %incptr = getelementptr %x, 1 We will basically always return MayAlias for %x and any other value because aliasPHI recurses on the first value and gives up. There are, however, many cases where this is too conservative. Take the following example: typedef struct { unsig...
