In r271810 ( http://reviews.llvm.org/rL271810 ), I loosened the check
above this to work for any Constant rather than ConstantInt. AFAICT,
that part makes sense if we can determine that the shrunken/extended
constant remained equal. But it doesn't make sense for this later
transform where we assume that the constant DID change.
This could assert for a ConstantExpr:
https://llvm.org/bugs/show_bug.cgi?id=28011
And it could be wrong for a vector as shown in the added regression test.

This commit adds a static analysis checker to check for the correct usage of the
MPI API in C and C++.
3 path-sensitive checks are included:
- Double nonblocking: Double request usage by nonblocking calls
without intermediate wait.
- Missing wait: Nonblocking call without matching wait.
- Unmatched wait: Waiting for a request that was never used by a
nonblocking call.
Examples of how to use the checker can be found
at https://github.com/0ax1/MPI-Checker

This is a very simple optimization that gets about 10% speedup for certain programs. We’re currently storing the pointer to the main thread’s ThreadState, but we can store the state directly in a static variable, which avoid the load acquire.

Somehow, in r271049, ASan lit tests and unit tests were removed from “check-all”. Doesn’t seem intentional, let’s fix it.

Mention that the code coverage tool becomes less precise whenever
unpredictable changes in control flow occur.
Thanks to Sean Silva for pointing this out!

Another step for unification llvm assembler/disassembler with sp3.
Besides, CodeGen output is a bit improved, thus changes in CodeGen tests.
Assembler/Disassembler tests updated/added.

Summary:
Because PIE executables have an e_type of llvm::ELF::ET_DYN,
they are not of type eTypeExecutable, and were being removed
when svr4 packets were used.

This patch refactors the code generation for divisions. This allows to
always generate a shift for a power-of-two division and to utilize
information about constant divisors in order to truncate the result
type.

We now generate runtime checks __after__ the SCoP code generation and
not before, though they are still inserted at the same position int
the code. This allows to modify the runtime check during SCoP code
generation.

match was the ld.elf_so that should be matched in a second step. Add one
of the ever-present-but-irrelevant-for-this-test arguments to the
pattern to force matching the right argument.

IntToPtr and PtrToInt instructions are basically no-ops that we can handle as
such. In order to generate them properly as parameters we had to improve the
ScopExpander, though the change is the first in the direction of a more
aggressive scalar synthetization.

Summary:
32-bit CPU's default to O32. 64-bit CPU's default to N64. The default CPU
(mips32r2/mips64r2) still depends on the arch so there's no functional
change when the CPU isn't specified but commands like:
clang -target mips-mti-linux-gnu -mips64r2
will now default to a 64-bit ABI like our gcc toolchains do* instead of
asserting in the backend**.
Other vendors (including Triple::UnknownVendor) still derive the default
ABI from the arch.
* Although not the same one as our gcc toolchains, clang has historically
defaulted to N64 where gcc defaults to N32.
** Mixing O32 and a 64-bit CPU causing assertions is a long-standing bug.

We now use the minimal necessary bit width for the generated code. If
operations might overflow (add/sub/mul) we will try to adjust the types in
order to ensure a non-wrapping computation. If the type adjustment is not
possible, thus the necessary type is bigger than the type value of
--polly-max-expr-bit-width, we will use assumptions to verify the computation
will not wrap. However, for run-time checks we cannot build assumptions but
instead utilize overflow tracking intrinsics.

return NULL for an invalid register.
The unwind logic asks for the "return address register" which doesn't exist
on x86/x86_64, returns -1 and calls this with -1 as a parameter, ends up
out of scope of the array bounds for g_register_infos and later SIGSEGVs
on accessing. This now matches the other GetRegisterInfoAtIndex for
other platforms.

Summary:
setABI() is still tied to the Arch component of the Triple to preserve existing

With CMP0056, try_compile() uses also CMAKE_EXE_LINKER_FLAG.
It caused mismatch between CMAKE_CXX_FLAGS and CMAKE_EXE_LINKER_FLAGS, to fail to examine CXX_SUPPORTS_CXX11 with -m32.
FYI, before this, try_compile() tries without -m32 regardless of LLVM_BUILD_32_BITS.

Now it gives the StmtClass of the Expr as well as the type. It's still
a long way from full visualization of expressions, but I have found
that having the class really helps when debugging, so definitely
worth submitting.

This chapter discusses IR optimizations, the ORC IRTransformLayer, and the ORC

The text is still pretty rough, but I think the main ideas are there. Feedback
