Bug ID: 22279
Summary: alignment specifier ignored on enum definitions
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: C++11
Assignee: unassignedclangbugs at nondot.org
Reporter: richard-llvm at metafoo.co.uk
CC: dgregor at apple.com, llvmbugs at cs.uiuc.edu
Classification: Unclassified
Consider:
enum alignas(64) X : int {} x;
static_assert(alignof(X) == 64, "");
This fails: the assert fires, and if you remove it, we generate code that has
an underaligned global 'x'.
Same thing happens for __attribute__((aligned(N))) (but in that case, we're at
least being GCC-compatible).
Conversely, consider:
typedef __attribute__((aligned(64))) N;
enum X : N {} x;
Here, we *do* apply the alignment to X. It's not obvious whether we should. GCC
does. EDG does not.
