Bug ID: 61413
Summary: __ARM_SIZEOF_WCHAR_T is constant 32 -- should be 4 or
2
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: ilya.konstantinov at gmail dot com
ARM EABI mandates __ARM_SIZEOF_WCHAR_T that reflects the wchar size:
"wchar_t may be 2 or 4 bytes. The predefined macro __ARM_SIZEOF_WCHAR_T should
be defined as the same number." [1]
However, on gcc we have the following built-in defines:
#define __ARM_SIZEOF_WCHAR_T 32
while it should be:
#define __ARM_SIZEOF_WCHAR_T 4
or with -fshort-wchar:
#define __ARM_SIZEOF_WCHAR_T 2
[1]

ARM ACLE mandates this, not ARM EABI.
Confirmed and broken everywhere. Simple fix in progress.
