IBM AIX
On IBM AIX, TotalView supports compiled and interpreted expressions. TotalView also supports assembler in expressions.
Some program functions called from the TotalView expression system on the Power architecture cannot have floating-point arguments that are passed by value. However, in functions with a variable number of arguments, floating-point arguments can be in the varying part of the argument list. For example, you can include floating-point arguments with calls to printf:
double d = 3.14159;
printf("d = %f\n", d);
