// Test frontend handling of __sync builtins.
// Modified from a gcc testcase.
// RUN: %llvmgcc -S %s -o - | grep atomic | count 150
// RUN: %llvmgcc -S %s -o - | grep p0i8 | count 50
// RUN: %llvmgcc -S %s -o - | grep p0i16 | count 50
// RUN: %llvmgcc -S %s -o - | grep p0i32 | count 50
// RUN: %llvmgcc -S %s -o - | grep volatile | count 6

// Currently this is implemented only for Alpha, X86, PowerPC.
// Add your target here if it doesn't work.
// This version of the test does not include long long.
// XFAIL: sparc|arm
