8 years agoARM: use a pseudo-instruction for cmpxchg at -O0.
Tim Northover [Mon, 18 Apr 2016 21:48:55 +0000 (21:48 +0000)]
ARM: use a pseudo-instruction for cmpxchg at -O0.

The fast register-allocator cannot cope with inter-block dependencies without
spilling. This is fine for ldrex/strex loops coming from atomicrmw instructions
where any value produced within a block is dead by the end, but not for
cmpxchg. So we lower a cmpxchg at -O0 via a pseudo-inst that gets expanded
after regalloc.

Fortunately this is at -O0 so we don't have to care about performance. This
simplifies the various axes of expansion considerably: we assume a strong
seq_cst operation and ensure ordering via the always-present DMB instructions
rather than v8 acquire/release instructions.

Should fix the 32-bit part of PR25526.

Fix trip count calculation for parallel loops in runtime

The trip count calculation was incorrect for loops with large bounds. For example,
for(int i=-2,000,000,000; i < 2,000,000,000; i+=50000000), the trip count
calculation had overflow (trying to calculate 2,000,000,000 + 2,000,000,000 with
signed integers) and wasn't giving the right value. This patch fixes this error
in the runtime by using unsigned integers instead. There is still a bug in the
clang compiler component because it warns that there is overflow in the
test case file when there isn't. This error isn't there for the Intel Compiler.

Fix for pthread_setspecific (TLS and shutdown) problem

Some codes that use TLS fail intermittently because one thread tries to write
TLS values after the TLS key has been destroyed by another thread. This happens
when one thread executes library shutdown (and destroys TLS keys), while another
thread starts to execute the TLS key destructor routine. Before this change, the
kmp_init_runtime flag was checked before calling pthread_* TLS functions, but
this flag is set to FALSE later than the destruction of the TLS keys, which
leads to failure. The fix is to check kmp_init_gtid instead, as this flag is

[ORC] Generalize the ORC RPC utils to support RPC function return values and
asynchronous call/handle. Also updates the ORC remote JIT API to use the new
scheme.

The previous version of the RPC tools only supported void functions, and
required the user to manually call a paired function to return results. This
patch replaces the Procedure typedef (which only supported void functions) with
the Function typedef which supports return values, e.g.:

  Function<FooId, int32_t(std::string)> Foo;

The RPC primitives and channel operations are also expanded. RPC channels must
support four new operations: startSendMessage, endSendMessage,
startRecieveMessage and endRecieveMessage, to handle channel locking. In
addition, serialization support for tuples to RPCChannels is added to enable
multiple return values.

The RPC primitives are expanded from callAppend, call, expect and handle, to:

appendCallAsync - Make an asynchronous call to the given function.

callAsync - The same as appendCallAsync, but calls send on the channel when
            done.

callSTHandling - Blocking call for single-threaded code. Wraps a call to
                 callAsync then waits on the result, using a user-supplied
                 handler to handle any callbacks from the remote.

callST - The same as callSTHandling, except that it doesn't handle
         callbacks - it expects the result to be the first return.

expect and handle - as before.

handleResponse - Handle a response from the remote.

waitForResult - Wait for the response with the given sequence number to arrive.
