Summary: llvm2cpp service dies when fed code with dynamic
labels
Product: Website
Version: unspecified
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P
Component: General Website
AssignedTo: [email protected]

Summary:
When compiling C code with dynamic gotos and asking llvm2cpp to show library
calls, it dies from a "Bad constant" error.
Steps to reproduce:
1. Go to http://llvm.org/demo/index.cgi
2. Enter a program that has dynamic gotos:
#include <time.h>
int main() {
void* array[] = {&&foo, &&bar};
goto *array[time(NULL) % 2];
foo: return 1;
bar: return 2;
return 0;
}
3. Check "Show LLVM C++ API Code"
4. Click "Compile Source Code"
Expected results:
It should display the appropriate API calls to generate such instructions.
Actual Results:
llvm2cpp dies because of a "Bad Constant" error, even though the compiler
managed to make valid LLVM bytecode out of the C code.
