| 2 | This XQuery loads a GCC-XML file and reports the locations of all
|
|---|
| 3 | global variables in the original C++ source. To run the query,
|
|---|
| 4 | use the command line:
|
|---|
| 5 |
|
|---|
| 6 | xmlpatterns reportGlobals.xq -param fileToOpen=globals.gccxml -output globals.html
|
|---|
| 7 |
|
|---|
| 8 | "fileToOpen=globals.gccxml" binds the file name "globals.gccxml"
|
|---|
| 9 | to the variable "fileToOpen" declared and used below.
|
|---|
| 10 | :)

| 18 | correct, we should check whether the class has a non-synthesized
|
|---|
| 19 | constructor. We accept both mutable and const types.
