* LegalizeDAG: Fix and improve FCOPYSIGN/FABS legalizationMatthias Braun2015-11-123-79/+152
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Factor out code to query and modify the sign bit of a floatingpoint value as an integer. This also works if none of the targets integer types is big enough to hold all bits of the floatingpoint value. - Legalize FABS(x) as FCOPYSIGN(x, 0.0) if FCOPYSIGN is available, otherwise perform bit manipulation on the sign bit. The previous code used "x >u 0 ? x : -x" which is incorrect for x being -0.0! It also takes 34 instructions on ARM Cortex-M4. With this patch we only require 5: vldr d0, LCPI0_0 vmov r2, r3, d0 lsrs r2, r3, #31 bfi r1, r2, #31, #1 bx lr (This could be further improved if the compiler would recognize that r2, r3 is zero). - Only lower FCOPYSIGN(x, y) = sign(x) ? -FABS(x) : FABS(x) if FABS is available otherwise perform bit manipulation on the sign bit. - Perform the sign(x) test by masking out the sign bit and comparing with 0 rather than shifting the sign bit to the highest position and testing for "<s 0". For x86 copysignl (on 80bit values) this gets us: testl $32768, %eax rather than: shlq $48, %rax sets %al testb %al, %al Differential Revision: http://reviews.llvm.org/D11172 llvm-svn: 252839

This matches the existing backend failure to inline functions that don't have matching target features - and diagnoses earlier in the case of always_inline. Fix up a few test cases that were, in fact, invalid if you tried to generate code from the backend with the specified target features and add a couple of tests to illustrate what's going on.

* [IR] Add support for empty tokensDavid Majnemer2015-11-1114-14/+86
| | | | | | | | | | | | | | When working with tokens, it is often the case that one has instructions which consume a token and produce a new token. Currently, we have no mechanism to represent an initial token state. Instead, we can create a notional "empty token" by inventing a new constant which captures the semantics we would like. This new constant is called ConstantTokenNone and is written textually as "token none". Differential Revision: http://reviews.llvm.org/D14581 llvm-svn: 252811

* Introduce deoptimization operand bundlesSanjoy Das2015-11-115-0/+56
| | | | | | | | | | | | | | | | | | | | | Summary: This change introduces the notion of "deoptimization" operand bundles. LLVM can recognize and optimize these in more precise ways than it can a generic "unknown" operand bundles. The current form of this special recognition / optimization is an enum entry in LLVMContext, a LangRef blurb and a verifier rule. Over time we will teach LLVM to do more aggressive optimization around deoptimization operand bundles, exploiting known facts about kinds of state deoptimization operand bundles are allowed to track.

* [analyzer] Fix scan-build to handle missing output directories.Devin Coughlin2015-11-111-1/+3
| | | | | | | | | | | | | Cwd::abs_path has a somewhat tricky semantics: if it's operand directory does not exist, it'll return undefined (see https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=257568). This may cause scan-build to silently ignore output directory (specified with -o) and use /tmp instead of trying to create directory. This tiny patch fixes the problem. A patch by Yury Gribov!

* Move the enum attributes defined in Attributes.h to a table-gen file.Akira Hatanaka2015-11-118-59/+250
| | | | | | | | | | | | | | This is a step towards consolidating some of the information regarding attributes in a single place. This patch moves the enum attributes in Attributes.h to the table-gen file.

* Create `PythonTuple` and `PythonCallable` wrapper classes.Zachary Turner2015-11-113-17/+454

Additionally, unit tests are provided that exercise this functionality, including invoking manipulating and checking for validity of tuples, and invoking and checking for validity of callables using a variety of different syntaxes. The goal here is to eventually replace the code in python-wrapper.swig that directly uses the Python C API to deal with callables and name resolution with this code that can be more easily tested and debugged. llvm-svn: 252787
