Running
target datalayout = "e-m:e-i8:8:32-i16:16:32-i64:64-i128:128-n32:64-S128"
target triple = "aarch64-unknown-linux-gnu"
define i64 @test(i64* %p) #0 {
%x = load i64, i64* %p, align 1
ret i64 %x
}
attributes #0 = { "target-features"="+strict-align" }
through llc -O0 results in:
ldr x0, [x0]
ret
Which violates strict-align. Passing -global-isel=false avoids the issue.</pre>
