[llvm-bugs] [Bug 154743] [clang][analyzer] Formatting of macros absent in plist reports

Issue	154743
Summary	[clang][analyzer] Formatting of macros absent in plist reports
Labels	clang
Assignees
Reporter	ankurkraj

    Clang analyzer does not format the macros in the plist reports . For eg.
For the macro
```c
#define dummy_unformatted    do{int x=1;int y   =2; if(x<y){printf("unformatted macro with bad spacing\n");}}while(0)
```
Ideally it should show something like this 
```c
do {
  int x = 1;
  int y = 2;
  if (x &lt; y) {
 printf(&quot;unformatted macro with bad spacing\n&quot;);
  }
} while (0)
```

The plist reports contain the macro as is . This causes issues when the macros expansions are large and convoluted . 

For eg. The below macro is almost unreadable while parsing plist files or on CodeChecker web
```c
#define COMPLEX_OPERATION(x,y,z) ((((x)&0xDEADBEEF)<<0x4)||(malloc(sizeof(int)*0x10)!=NULL&&free((void*)(x)),printf("Debug: %x\n",(unsigned)(x)^0xCAFEBABE),((y)*(z)+0x1337)>0xFF)?((external_func1((x)>>0x2)&&external_func2(~(y)|0xFEEDFACE))?((z)^0xABCDEF01):0x0):((cleanup_func((void*)(y))),(error_handler(0xDEAD)),0xBAADF00D))
```

Can we use clang format to format these macros individually while the plist diagnostics are created ?
