According to my understanding, it works for consecutive registers as I am just declaring an array in my test case. To be specific, how do I get "rodata" section in assembly generated that contains only the data(integers) in the array declared,, because when I compile with other already build processors, it creates this rodata section and then using a single instruction stores all the elements of array in memory. noeljohn -- View this message in context: http://old.nabble.com/Emission-of-store_multiple-and-load_multiple-patterns-tp26739724p26775192.html Sent from the gcc - Help mailing list archive at Nabble.com.
