LLVM backend for 6502
This occurs in C++ code like: #include <iostream> #include <iterator> int a[] = { 1, 2, 3, 4, 5 }; int main() { using namespace std; copy(a, a + sizeof(a)/sizeof(a[0]), ostream_iterator<int>(cout, "\n")); return 0; } Before we would decide the loop trip count is: sdiv (i32 sub (i32 ptrtoint (i32* getelementptr ([5 x i32]* @a, i32 0, i32 5) to i32), i32 ptrtoint ([5 x i32]* @a to i32)), i32 4) Now we decide it is "5". Amazing. This code will need to be refactored, but I'm doing that as a separate commit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33665 91177308-0d34-0410-b5e6-96231b3b80d8 |
