IR: Enable debug info type ODR uniquing for forward decls

Add a new method, DICompositeType::buildODRType, that will create or
mutate the DICompositeType for a given ODR identifier, and use it in
LLParser and BitcodeReader instead of DICompositeType::getODRType.

The logic is as follows:

  - If there's no node, create one with the given arguments.
  - Else, if the current node is a forward declaration and the new
    arguments would create a definition, mutate the node to match the
    new arguments.
  - Else, return the old node.

This adds a missing feature supported by the current DITypeIdentifierMap
(which I'm slowly making redudant).  The only remaining difference is
that the DITypeIdentifierMap has a "the-last-one-wins" rule, whereas
DICompositeType::buildODRType has a "the-first-one-wins" rule.

For now I'm leaving behind DICompositeType::getODRType since it has
obvious, low-level semantics that are convenient for unit testing.

When stopping the private state thread, there was a race condition between the time the thread exits (resetting the HostThread object) and the time a Join was attempted, especially in the case of a timeout.

The previous workaround of copying the HostThread object is not enough, since on a Reset the internal thread stuff gets nulled out regardless of which HostThread object actually has Reset called on it, resulting in an attempt to dereference a null pointer on the subsequent call to Join from the copy as well.

Additionally, there was a race between the detach (called when stopping the process) and the stop itself, causing the stop to time out because it was waiting for the private state thread to see the stop state, but it had exited immediately after entering the detached state.

8 years agoFramework to allow testing of static libc++abi
Ben Craig [Tue, 19 Apr 2016 12:49:05 +0000 (12:49 +0000)]
Framework to allow testing of static libc++abi

These changes make linking against static libraries more explicit. Instead
of using -lc++ and -lc++abi in the tests, an absolute path to the library is
provided instead.

The choices of shared vs. static, and the choices of library paths for both
libcxx and libcxxabi needed to be exchanged for this to work. In other words,
libcxx tests need to know the library path of libcxxabi, and whether libcxxabi
is a static or shared library.

Some Mac specific logic for testing against libc++abi had to be moved from
libcxxabi's config.py, as it was overriding choices made in libcxx's config.py.
That logic is now in libcxx's target_info.py.

Testing a static libcxx on Linux will now automatically link in librt most of
the time. Previously, lots of pthread tests would fail because of an
unresolved clock_gettime.

Manifest file is a separate or embedded XML file having metadata

information. Probably the most popular one is to request escalated
priviledges.

command line. /manifestniput is it.

manifest files, then the linker needs to merge the files into a

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.

8 years agoFix trip count calculation for parallel loops in runtime

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.
So for now, the test case is designated as XFAIL.

Runtime support for untied tasks

Introduced a counter of parts of an untied task submitted for execution. The
counter controls whether all parts of the task are already finished. The
compiler should generate re-submission of partially executed untied task by
itself before exiting of each task part except for the lexical last part.

Jonathan Peyton [Mon, 18 Apr 2016 21:33:01 +0000 (21:33 +0000)]
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
unset *before* the destruction of TLS keys.
