* Joseph Myers: > This patch removes the IEEE_DOUBLE_BIG_ENDIAN and > IEEE_DOUBLE_MIXED_ENDIAN macros from gmp-impl.h and gmp-mparam.h, and > the ieee_double_extract union from gmp-impl.h. The macros were used > only in defining the union, which was used nowhere in glibc. As GMP's > gmp-impl.h is over 5000 lines, the file in glibc is so far from the > GMP version that it doesn't seem to make sense to keep things there > that are not relevant in glibc. (I expect there is plenty more in the > header after this patch that is also not relevant in glibc and can be > cleaned up later.) > > Tested with build-many-glibcs.py that installed stripped shared > libraries are unchanged by this patch. Thanks. This looks okay to me.
