* | Fix powerpc-nofpu __fe_enabled_env and __fe_nonieee_env (bug 17261). | Joseph Myers | 2014-08-12 | 1 | -4/+4 |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On powerpc, floating-point environment macros are defined as pointers to constants in the library that contain the bit-patterns of the desired environment, instead of being magic constants cast to pointer type. For soft-float, the bit-patterns used for fenv_t are not laid out the same as for hard-float. (e500 has a third layout used; that's not an ABI issue because these values are only meaningful within a single process, all of whose glibc libraries must come from the same build of glibc.) While the __fe_dfl_env value for soft-float was appropriate for the soft-float fenv_t representation, the other two constants had the same bit-patterns as for hard-float. Those bit patterns had the effect of having exceptions already raised, causing math/test-fenv-return to fail; this patch fixes the patterns used. (__fe_nonieee_env also had exceptions unmasked, though they should be masked to match hard-float semantics. Since there is no separate non-IEEE mode for soft-float, it's most appropriate for __fe_nonieee_env to be the same as __fe_dfl_env; this patch makes it an alias.) Tested for powerpc-nofpu. [BZ #17261] * sysdeps/powerpc/nofpu/fenv_const.c (__fe_enabled_env): Change value to 0. (__fe_nonieee_env): Define as an alias for __fe_dfl_env. | ||||
