Date: Sun, 30 Jan 2000 16:44:00 -0000 [thread overview] Message-ID: <Pine.GSO.3.96.1000131082647.11711A-100000@felix.os.nctu.edu.tw> (raw) Good days, and sorry for the inconvenience I made ^_^ I don't know if this is a bug, or just a misunderstanding :-P I am currently using the GCC as a corss-compiler which target is VAX machine. The host is i386 arch with linux. Here is the test program I wrote: main( ) { unsigned int a, b; a = 10; b = 5; a = a % b; } In the VAX-assembly, it calls "umodsi3" to achieve mod of the two unsigned integer. However, in libgcc1.c, the umodsi3 is also implemented in following statements: #define perform_umodsi3(a, b) return a % b nongcc_SI_type __umodsi3 (a, b) unsigned nongcc_SI_type a, b; { perform_umodsi3 (a, b); } As a result, we can't use this compiler to compile libgcc1.c in order to provide the unsigned integer mod. This situation becames to a self-calling recurrsive. Some other machine is containing this umodsi3 in ".md" file but Vax is not. Should we patch this one to vax.md or in libgcc1? (to emulate umodsi3 with signed integer?) Thank you in advance :-) ================== Kuo-Yu Slayer Chuang Computer & Communications Research Laboratories Software Engineer Industrial Technology Research Institute, Taiwan.
