| 1024 While making the OS and the compiler able to work on 64b | |
| 1025 architectures, SGI designed another mode for using registers | |
| 1026 and passing parameters between functions, activated on the | |
| 1027 compiler by using -64. Since it was much more efficient ar | |
| 1028 using registers even for 32b architectures, they designed | |
| 1029 a version for 32b called n32. And it _is_ really better. | |
| 1030 This mode should always be used when not using gcc (which | |
| 1031 can only do o32 afaik). | |
| 1032 | |
| 1033 Too bad xemacs can't do n32 out of the box. So here is what | |
| 1034 I had to do to compile it in this mode: | |
| 1035 | |
| 1036 s/irix6-0.h: | |
| 1037 - #define LD_SWITCH_SYSTEM -32 | |
| 1038 + #define LD_SWITCH_SYSTEM -n32 -G 0 | |
| 1039 | |
| 1040 m/iris4d.h: | |
| 1041 - #define LIBS_MACHINE -lmld | |
| 1042 + #define LIBS_MACHINE | |
| 1043 | |
| 1044 - #define C_SWITCH_MACHINE -32 | |
| 1045 + #define C_SWITCH_MACHINE -n32 -G 0 | |
| 1046 | |
| 1047 (the mld lib does not exist in n32 mode) | |
| 1048 | |
| 1049 I also added a --cflags='-n32 -O2 -G 0 -s' to the configuration | |
| 1050 line but it seems that these flags are ignored for configure test | |
| 1051 and since o32 and n32 libraries are independant I had to revert | |
| 1052 to the CFLAGS env var. | |
| 1053 | |
| 1054 Anyway, once done that the compile has gone succesfully, the dump | |
| 1055 was OK and I'm writing this in the resulting xemacs-20.2b1 ;-) | |
