MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit gcc/ 2013-06-16 Jürgen Urban * config/mips/mips.h (ISA_HAS_MUL3): Include TARGET_MIPS5900. (ISA_HAS_MULT, ISA_HAS_DMULT, ISA_HAS_DIV, ISA_HAS_DDIV): New macros. * config/mips/mips.md (mul3, mul3_internal) (mul3_r4000): Require ISA_HAS_MULT. (mul3_mul3): Handle TARGET_MIPS5900. (mulsidi3_64bit_dmul): Remove redundant TARGET_64BIT test. (muldi3_highpart, muldi3_highpart_internal, mulditi3) (mulditi3_internal, mulditi3_r4000): Require ISA_HAS_DMULT instead of TARGET_64BIT. (divmod4, udivmod4, divmod4_hilo_): Require ISA_HAS_DIV. libgcc/ 2013-06-16 Jürgen Urban * config/mips/lib2funcs.c: New file. * config/mips/t-mips (LIB2ADD_ST): Add it.
