Bug ID: 19999
Summary: fail to respect __attribute__((aligned)) on typedef
used as type of field
Product: clang
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Frontend
Assignee: unassignedclangbugs at nondot.org
Reporter: richard-llvm at metafoo.co.uk
CC: llvmbugs at cs.uiuc.edu
Classification: Unclassified
typedef __attribute__((aligned(32))) char &cr;
struct S { char a; cr q; };
static_assert(alignof(cr) == 1, "");
static_assert(alignof(S::q) == 1, "");
static_assert(sizeof(S) == 64, "");
All of those static_asserts should pass, but currently the last one fails. We
apparently don't pick up 'aligned' attributes on typedefs when performing
record layout.
