// This test covers 5 cases of sampler initialzation:
|
|
// 1. function argument passing
|
|
// 1a. argument is a file-scope variable
|
|
// 1b. argument is a function-scope variable
|
|
// 1c. argument is one of caller function's parameters
|
|
// 2. variable initialization
|
|
// 2a. initializing a file-scope variable
|

// 2b. initializing a function-scope variable
