1124 | (sim_{trace,create_inferior}): Eliminate extraneous output unless | |
1125 | debugging. | |
1126 | (sim_open): If args == -t and DEBUG was defined, set d10v_debug. | |
1127 | Only initialize the hash table the first time sim_open is called. | |
1128 | ||
1129 | * Makefile.in: Make objects depend on d10v_sim.h. | |
1130 | ({,SIM_}CFLAGS): Include configure dependent switches. Setting | |
1131 | CFLAGS does not override host/target defines or SIM_CFLAGS. | |
1132 | (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode. | |
1133 | (run): By default, the math library is not needed to be linked | |
1134 | in. | |
1135 | ({BFD,LIBIBERTY}_LIB): Define as variables so they can be | |
1136 | overridden. | |
1137 | (VPATH): Don't set to anything but @srcdir@ to work with non-GNU | |
1138 | makes. | |
1139 | ({run,callback}.o): Provide explicit paths to their appropriate | |
1140 | source directories. | |
1141 | (gencode{,.o},d10v-opc.o): Split compilation into creating object | |
1142 | and linking. Instead of linking in libopcodes.a, just compile | |
1143 | d10v-opc.o directly to handle canadian cross. | |
1144 | (CSEARCH): Add opcodes directory. | |
1145 | ||
1146 | * configure.in (--enable-sim-cflags): New switch to allow user to | |
1147 | set the defaults. | |
1148 | (CC_FOR_BUILD): Deal with canadian crosses. | |
1149 | * configure: Regenerate. | |
