示例1: DisambiguateGlobalSymbols
/// DisambiguateGlobalSymbols - Mangle symbols to guarantee uniqueness by
/// modifying predominantly internal symbols rather than external ones.
///
static void DisambiguateGlobalSymbols(Module *M) {
// Try not to cause collisions by minimizing chances of renaming an
// already-external symbol, so take in external globals and functions as-is.
// The code should work correctly without disambiguation (assuming the same
// mangler is used by the two code generators), but having symbols with the
// same name causes warnings to be emitted by the code generator.
Mangler Mang(*M);
// Agree with the CBE on symbol naming
Mang.markCharUnacceptable('.');
for (Module::global_iterator I = M->global_begin(), E = M->global_end();
I != E; ++I) {
// Don't mangle asm names.
if (!I->hasName() || I->getName()[0] != 1)
I->setName(Mang.getMangledName(I));
}
for (Module::iterator I = M->begin(), E = M->end(); I != E; ++I) {
// Don't mangle asm names or intrinsics.
if ((!I->hasName() || I->getName()[0] != 1) &&
I->getIntrinsicID() == 0)
