So, I played with this some more with this, and there seems to be some inconsistency in how these attributes get handled. http://sourceware.org/bugzilla/show_bug.cgi?id=13263 static inline int foo (int) __attribute__((always_inline,artificial)); static inline int foo (int x) { int y = x - 3; return y; } int bar (int y) { return y == 0; } main () { foo (10); return bar (foo (3)); } With GCC 4.7, the stand alone call foo(10) is not ignored by 'step'. However, the embedded call bar(foo(3)) is ignored as I was expecting. Diego.
