Endianness for multi-word types
Hi,
I'm recently trying to investigate ppc_fp128 related problem. Here is a
minimal C++ test case that seems wrongly compiled:
long double id(long double a) {
return a;
}
bool f(long double x) {
return id(__builtin_fabsl(x)) >= 0;
}
int main() {
if (f(-123.l)) {
return 0;
}
return 1;
}
The program compiled with command:
clang++ -static -target powerpc64le-linux-gnu bad.cc

[LLVMdev] Flag operands and load/store DAG nodes
I notice that many DAG nodes like the copy-to-register operation have
the ability to take an optional flag parameter, but that the load/store
nodes do not (at least as of 2.3). Is it possible to pass flag operands
through load/store DAG nodes?

No there isn't. What are you trying to accomplish? Are you trying to

Fwd: asan for allocas on powerpc64
(Resending with the correct mailing list address.)
Hi,
Currently test/asan/TestCases/alloca_vla_interact.cc is XFAILed for
powerpc64. I've had a look at why it doesn't work. I think the only
problem is in the call to __asan_allocas_unpoison that is inserted at
the end of the "for" loop (just before a stackrestore instruction).
The call function is created something like this
