Joseph Myers b75bc69cdf Don't use dbl-64/wordsize-64 lround based on llround for ILP32 (bug 19079). ... The implementation of lround in dbl-64/wordsize-64 as an alias or wrapper for llround is always incorrect when long is not 64-bit, because it misses required exceptions in overflow cases, as shown by my recently added tests. This patch removes that alias / wrapper in the non-LP64 case, together with the REGISTER_CAST_INT32_TO_INT64 macro, restoring the previous version of lround for dbl-64/wordsize-64 (newly conditioned on !_LP64). Tested for x86_64, and for mips64 with use of dbl-64/wordsize-64 enabled. [BZ #19079] * sysdeps/ieee754/dbl-64/wordsize-64/s_lround.c: Restore previous file, conditioned on [!_LP64]. * sysdeps/ieee754/dbl-64/wordsize-64/s_llround.c [!_LP64] (__lround): Do not define as function or alias. [!_LP64] (lround): Likewise. [!_LP64] (__lroundl): Likewise. [!_LP64] (lroundl): Likewise. * sysdeps/tile/sysdep.h (REGISTER_CAST_INT32_TO_INT64): Remove macro. * sysdeps/x86_64/x32/sysdep.h (REGISTER_CAST_INT32_TO_INT64): Likewise.		2015-10-07 00:40:12 +00:00
