[X86] Change register&memory TEST instructions from MRMSrcMem to MRMDstMem

Summary:
Intel documentation shows the memory operand as the first operand. But we currently treat it as the second operand. Conceptually the order doesn't matter since it doesn't write memory. We have aliases to parse with the operands in either order and the isel matching is commutable.

For the register&register form order does matter for the assembly parser. PR22995 was previously filed and fixed by changing the register&register form from MRMSrcReg to MRMDestReg to match gas. Ideally the memory form should match by using MRMDestMem.

I believe this supercedes D38025 which was trying to switch the register&register form back to pre-PR22995.

Saleem Abdulrasool [Sun, 1 Oct 2017 20:06:48 +0000 (20:06 +0000)]
SjLj: make the SjLj implementation more portable

This moves the definition of the internal helpers
`__Unwind_SjLj_GetTopOfFunctionStack` and
`__Unwind_SjLj_SetTopOfFunctionStack` into `Unwind-sjlj.c`.  These are
not extra functions specific to Apple, but rather are internal
implementation details of SjLj support in the LLVM libunwind
implementation.

This allows us to remove the internal header unwind_ext.h, as these
functions are not meant to be used as SPI either.  Because they are
static, they will be given implicit hidden visibility, but due to the
simplicity should get fully inlined into the actual use.

Use the C11 standard static TLS annotation (`_Thread_local`) if
possible, otherwise, use the Windows specific `__declspec(thread)` when
targeting Windows or the GNU `__thread` extension.  In theory, it should
be possible for this implementation to use a `pthread_setspecific` and
`pthread_getspecific` on platforms with pthreads or `SetFlsValue` and
`GetFlsValue` on Windows for non-static TLS.  However, static TLS tends
to be significantly faster, so we really should prefer that over the
dynamic TLS approach.  On Apple environments, when not building for the
loader (dyld), use the pre-allocated TLS slot in the loader rather than
the local static TLS variable.

Note that the un-threaded support of libunwind is still present as
before, however, it is unsafe to use in a threaded environment as the
cleanup stack may be mutated incorrectly due to lack of locking across
threads.  In the static TLS model, the lock is unneeded as each thread
of execution retains its own copy of the cleanup stack.

Take the opportunity to clean up the comment block, removing the iOS
specific note as the SjLj implementation can be used outside of the
context of iOS.  Convert the rest of the explanation to a doxygen style
comment block.

with predicated instructions (e.g., conditional stores and instructions that
may divide by zero). For these instructions, we create new basic blocks inside
the vectorized loop, which cause the loop header and latch to no longer be the
same block. This should fix PR34687.

7 years ago[llvm-rc] Refactoring needed for ACCELERATORS and MENU resources.

[llvm-rc] Refactoring needed for ACCELERATORS and MENU resources.

This is a part of llvm-rc serialization patch set (serialization, pt 1.5).

This:

* Unifies the internal representation of flags in ACCELERATORS and MENU
   with the corresponding representation in .res files (noticed in
   https://reviews.llvm.org/D37828#inline-329828).
* Creates an RCResource subclass, OptStatementsRCResource, describing
   resource statements that can declare resource-local optional statements
   (proposed in https://reviews.llvm.org/D37824#inline-329775).

These modifications don't fit to any of the current patches, so I'm
submitting them as a separate patch.

7 years ago[llvm-rc] Serialize HTML resources to .res files (serialization, pt 1).

[llvm-rc] Serialize HTML resources to .res files (serialization, pt 1).

This allows to process HTML resources defined in .rc scripts and output
them to resulting .res files. Additionally, some infrastructure allowing
to output these files is created.

This is the first resource type we can operate on.

Thanks to Nico Weber for his original work in this area.
