Hi, I'm having some strange compile problems with the malloc_test and tm module. The core compiles correctly but when I do make modules I get: *CC (gcc) [M malloc_test.so] malloc_test.o* */var/tmp//cc2iaGsC.s: Assembler messages:* */var/tmp//cc2iaGsC.s:1280: Error: suffix or operands invalid for `xadd'* */var/tmp//cc2iaGsC.s:1813: Error: suffix or operands invalid for `xadd'* */var/tmp//cc2iaGsC.s:2331: Error: suffix or operands invalid for `xadd'* *make[1]: *** [malloc_test.o] Error 1* If I remove the malloc_test module from compliation (As I am not using it) when I do make modules I get: *CC (gcc) [M tm.so] t_cancel.o* */var/tmp//ccWeaWKH.s: Assembler messages:* */var/tmp//ccWeaWKH.s:105: Error: suffix or operands invalid for `cmpxchg' * */var/tmp//ccWeaWKH.s:155: Error: suffix or operands invalid for `cmpxchg' * */var/tmp//ccWeaWKH.s:241: Error: suffix or operands invalid for `cmpxchg' * */var/tmp//ccWeaWKH.s:259: Error: suffix or operands invalid for `cmpxchg' * */var/tmp//ccWeaWKH.s:570: Error: suffix or operands invalid for `cmpxchg' * *make[1]: *** [t_cancel.o] Error 1* My machine is: SunOS HOST_NAME 5.11 snv_151a i86pc i386 i86pc Solaris and my gcc version is gcc version 3.4.3 (csl-sol210-3_4-20050802) I have successfully compiled and run this on an identical Solaris setup with the same Makefile configuration. Has anyone had a similar problem? Regards Richard.
