This test file compares the generated code size of similar functions between raw
|
|
COM interface pointers (|AddRef|ing and |Release|ing by hand) and |nsCOMPtr|s.
|
|
|
|
Function size results were determined by examining dissassembly of the generated code.
|
|
mXXX is the size of the generated code on the Macintosh. wXXX is the size on Windows.
|
|
For these tests, all reasonable optimizations were enabled and exceptions were
|
|
disabled (just as we build for release).
|
|
|
|
The tests in this file explore more complicated functionality: assigning a pointer
|
|
to be reference counted into a [raw, nsCOMPtr] object using |QueryInterface|;
|
|
ensuring that it is |AddRef|ed and |Release|d appropriately; calling through the pointer
|
|
to a function supplied by the underlying COM interface. The tests in this file expand
|
|
on the tests in "Test01.cpp" by adding |QueryInterface|.
|
|
|
|
Windows:
|
|
raw01 52
|
|
nsCOMPtr 63
|
|
raw 66
|
|
nsCOMPtr* 68
|
|
|
|
Macintosh:
|
|
nsCOMPtr 120 (1.0000)
|
|
Raw01 128 (1.1429) i.e., 14.29% bigger than nsCOMPtr
|
|
Raw00 144 (1.2000)
