------- Comment #3 from etienne_lorrain at yahoo dot fr 2008-08-24 09:13 ------- Moreover, if in the first test.c program, you declare variable "conf" volatile, the assembly generated contains 8 writes to "conf", and that memory location is *read* 7 times. If "conf" does not point to memory but to memory mapped I/O ports (maybe not readable), that is invalid code generated for valid input.
