[Clang Static Analyzer]: How to get name of Macro in Static Analyzer.

Clang Frontend

Hi all,

I am trying to write a check where I need name of the macro used in the source code.

E:g – (Sample source code)

#define SLEEP 20

#define WAKE 10

int g_var = 10;

U1 U1_Function()

{

If(g_var == 20) {

return (SLEEP); // I need to get the macro name in string format as ‘SLEEP’

}

return WAKE; // I need to get the macro name in string format as ‘WAKE’.

}

I am able to check if particular statement contains macro or not using ‘containsMacro’ function.

But I am not getting the actual macro name, though I tried using ‘getMacroNameOrSpelling’.

When I used ‘getMacroNameOrSpelling’, I either get ‘return’ or ‘(‘ in the string but not the actual macro name.

Kindly suggest me a way to get macro name in a Stmt.

Thanks in advance.
