Breaks in presence of nested conditions

[fbehrang]

Consider the following code, on LLVM 3.5, I use "clang -emit-llvm esc.c -c -o esc.bc" and then "llc -march=c esc.bc -o esc-out.c", after I compile esc-out.c, I get an error "else without a previous 'if' ". I also tried some other functions with nested if-else, the same thing happened.

int esc(char _s, int *i)
{
char result;
if (s[_i] != '@')
result = s[_i];
else
if (s[_i + 1] == '\0')
result = '@';
else
{
_i = *i + 1;
if (s[_i] == 'n')
result = 10;
else
if (s[_i] == 't')
result = 9;
else
result = s[_i];
}
return result;
}
