80b7b3a5 SG |
2227 | * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in |
2228 | into here. Makes insertion into makefiles easier. Also, change | |
2229 | the way that callback.o, gentmap, targ-vals.h, targ-map.c, | |
2230 | targ-map.o, and run are built. They are now built in the | |
2231 | individual simulator directories, taking sources from ../common as | |
2232 | necessary. This replaces the merging of libcommon.a into | |
2233 | linsim.a, which was problematic for the WinGDB build process. | |
2234 | * run.c: Include config.h from . instead of ../common. | |
2235 | * Make-common.in: Remove. It's no longer necessary. | |
