Hello,some people like having a macro to test if a type is available (__SIZEOF_INT128__ for instance). This adds macros for __float80 and __float128. The types seem to be always available, so I didn't add any condition.
If you think this is a bad idea, please close the PR. Bootstrap+testsuite on x86_64-linux-gnu. 2014-04-13 Marc Glisse <marc.gli...@inria.fr> PR preprocessor/56540 * config/i386/i386-c.c (ix86_target_macros): Define __SIZEOF_FLOAT80__ and __SIZEOF_FLOAT128__. -- Marc Glisse
