// - t_codepaging_dll Very simple dll, contains a single function. Used for testing state

18 |
// - t_codepaging_dll2 Contains 8 pages of data, used for testing the correct data is paged
|
|
sl@0

// - t_codepaging_dll3 Statically links to t_codepaging_sll, used for testing ReadExportDir
|

20 |
// - t_codepaging_dll4 Large dll, used for testing code segment that span more than one page
|

sl@0

|
22 |
// - t_codepaging_dll5 Contains relocatable const data.
