Expression System on IBM AIX-Power and Blue Gene/Q
On IBM AIX and Blue Gene/Q, TotalView supports compiled and interpreted expressions. TotalView also supports assembly language 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);
On Blue Gene/Q, currently TotalView supports only statically allocated patch spaces linked into the base executable. The executable may be statically or dynamically linked. The static patch space must not reside in a shared library. See Allocating Static Patch Space in the TotalView for HPC User Guide.
