// For asserts we'd like to keep all the junk executed when an assert happens away from the
|
|
|
|
// important code in the function. One way of doing this is to put all the relevant code inside a
|
|
|
|
// lambda and force the compiler to not inline it. Unfortunately, MSVC seems to have no syntax to
|
|
|
|
// specify __declspec on lambda functions, so what we do instead is define a noinline wrapper
|
|
|
|
// template that calls the lambda. This seems to generate an extra instruction at the call-site
|
|
|
|
// compared to the ideal implementation (which wouldn't support ASSERT_MSG parameters), but is good
|
|
|
|
// enough for our purposes.
