Bug #: 56540
Summary: No __SIZEOF__XXX__ macro for __float128
Classification: Unclassified
Product: gcc
Version: 4.7.2
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: preprocessor
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: j...@johnmaddock.co.uk
I'm not sure I have the component set right for this... this is possibly a C
and C++ compiler driver issue..?
As far as I can tell every builtin type has it's own __SIZEOF__XXX__ macro
defined in the preprocessor, which for example makes detecting __int128 support
easy via __SIZEOF_INT128__. However there are no corresponding macros for
__float80 and __float128. I'd like to see __SIZEOF_FLOAT80__ and
__SIZEOF_FLOAT128__ defined when these types are supported by the compiler.
