Bug ID: 45136
Summary: -Xclang -malign-double lowers alignment of long double
to 8
Product: clang
Version: 9.0
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P

Example
When compiling with `-Xclang -malign-double` the `alignof(long double)` returns
8, while without the flags it returns 16. Basically the alignment is lowered.
I am not sure if this is the intended behaviour, I guess that this flag should
only set alignment on `double` from 4 to 8 on 32-bit systems.
For comparison GCC returns 16 with or without the flag `-malign-double`.
Tested on Linux x86-64 and OSX x86-64 (clang also with `-m32`). I suppose that
for 64-bit builds it should do nothing but it still lowered the alignment.
