long long test2(unsigned A, unsigned B) { return ((unsigned long long)A << 32) + B; } is equivalent to this: long long test1(unsigned A, unsigned B) { return ((unsigned long long)A << 32) | B; } Now they are both codegen'd to this on ppc: _test2: blr or this on x86: test2: movl 4(%esp), %edx movl 8(%esp), %eax ret llvm-svn: 21231 |
