I had to see gdb disassembled output to figure out how gcc passes parameter to functions calls. it seems it passes them in register instead of using the stack as its 32-bit counter part does. now I wonder is there documentation that defines how this is done? is there a threshold of how many parameter it can pass this way before using the stack or some other means? best regards Katana Steel -- as life grows older, I gain experience. -- View this message in context: http://www.nabble.com/gcc-64-bit-%28assembly%29-information-tf4371985.html#a12461111 Sent from the gcc - Help mailing list archive at Nabble.com.
