Summary: Incorrect alignment from alloca
Product: new-bugs
Version: unspecified
Platform: PC
OS/Version: All
Status: NEW
Severity: normal
Priority: P2

When allocating memory with alloca for vectors on i386 the returned memory is
not always on 16 byte boundary as it has to be.
E.g.
a = alloca <2 x i64>
sometimes returns memory on 8 byte boundary, which means that using MMS
instructions to load and store will cause a fault.
