Hello, Could anyone tell me if there is a GCC equivalent of the pragmas used to control floating point arithmetic on a function-by-function basis in Microsoft Visual C++? (the pragmas are described here: http://msdn.microsoft.com/en-us/library/aa289157%28v=vs.71%29.aspx#floapoint_topic7 ) Specifically, I have a function for which I need to guarantee that no associative arithmetic optimizations are performed, i.e., I need to force -fno-associative-math to be used, but only around this particular function. Thanks for your help, Simon.
