* InstSimplify: Fold gep X, (sub 0, ptrtoint(X)) to nullDavid Majnemer2014-08-261-21/+32
| | | | | | | Save InstCombine some work if we can perform this fold during InstSimplify. llvm-svn: 216441
* InstSimplify: Simplify trivial pointer expressions like b + (e - b)David Majnemer2014-08-261-5/+36
| | | | | | | | | | | | | | | | | | | | | | | | consider: long long *f(long long *b, long long *e) { return b + (e - b); } we would lower this to something like: define i64* @f(i64* %b, i64* %e) { %1 = ptrtoint i64* %e to i64 %2 = ptrtoint i64* %b to i64 %3 = sub i64 %1, %2 %4 = ashr exact i64 %3, 3 %5 = getelementptr inbounds i64* %b, i64 %4 ret i64* %5 } This should fold away to just 'e'. N.B. This adds m_SpecificInt as a convenient way to match against a particular 64-bit integer when using LLVM's match interface. llvm-svn: 216439

* Declare that musttail calls in variadic functions forward the ellipsisReid Kleckner2014-08-263-3/+30
| | | | | | | | | | | | | | | | | Summary: There is no functionality change here except in the way we assemble and dump musttail calls in variadic functions. There's really no need to separate out the bits for musttail and "is forwarding varargs" on call instructions. A musttail call by definition has to forward the ellipsis or it would fail verification.

* ArgPromotion: Don't touch variadic functionsReid Kleckner2014-08-251-0/+7
| | | | | | | | | | | | | | | | Adding, removing, or changing non-pack parameters can change the ABI classification of pack parameters. Clang and other frontends encode the classification in the IR of the call site, but the callee side determines it dynamically based on the number of registers consumed so far. Changing the prototype affects the number of registers consumed would break such code. Dead argument elimination performs a similar task and already has a similar check to avoid this problem. Patch by Thomas Jablin! llvm-svn: 216421
* [MCJIT][SystemZ] Use a simpler expression for indirect relocation offsets.Lang Hames2014-08-251-1/+1
| | | | | | | | The expressions 'Reloc.Addend - Addend' and 'Reloc.Offset' should always be equal in this context. The latter is prefered - we want to remove the RelocationValueRef::Addend field in the future. llvm-svn: 216418
* Fix bug in llvm::sys::argumentsFitWithinSystemLimits().Rafael Espindola2014-08-251-2/+2
| | | | | | | | | | | | | This patch fixes a subtle bug in the UNIX implementation of llvm::sys::argumentsFitWithinSystemLimits() regarding the misuse of a static variable. This bug causes our cached number that stores the system command line maximum length to be halved after each call to the function. With a sufficient number of calls to this function, it will eventually report any given command line string to be over system limits. Patch by Rafael Auler. llvm-svn: 216415
* [MCJIT] Dump section memory both before and after relocations are applied.Lang Hames2014-08-251-5/+8
| | | | | | Also switch section memory dump format from 8 to 16 columns. llvm-svn: 216413
* Refactor argument serialization logic when executing process. NFC.Rafael Espindola2014-08-251-13/+17
| | | | | | | | | | | | This patch refactors the argument serialization logic used in the Execute function, used to launch new Windows processes. There is a critical step that joins char** arguments into a single string, building the command line used to launch the new process, and the readability of this code is improved if this part is refactored in its own helper function. Patch by Rafael Auler! llvm-svn: 216411
* [FastISel][AArch64] Refactor float zero materialization. NFCI.Juergen Ributzka2014-08-251-20/+29

* [MCJIT] Make RuntimeDyld dump section contents in -debug mode.Lang Hames2014-08-252-4/+34

* Modernize raw_fd_ostream's constructor a bit.Rafael Espindola2014-08-2515-79/+72
| | | | | | | | | | Take a StringRef instead of a "const char *". Take a "std::error_code &" instead of a "std::string &" for error. A create static method would be even better, but this patch is already a bit too big. llvm-svn: 216393
* [x86] Fix a bug in r216319 where I was missing a 'break'.Chandler Carruth2014-08-251-0/+2
| | | | | | | | | | | This actually was caught by existing tests but those tests were disabled with an XFAIL because of PR20736. While working on fixing that, I noticed the test failure, and tracked it down to this. We even have a really nice Clang warning that would have caught this but it isn't enabled in LLVM! =[ I may look at enabling it. llvm-svn: 216391
* Remove dangling initializers in GlobalDCEBruno Cardoso Lopes2014-08-252-1/+10
| | | | | | | | | | | | | | GlobalDCE deletes global vars and updates their initializers to nullptr while leaving underlying constants to be cleaned up later by its uses. The clean up may never happen, fix this by forcing it every time it's safe to destroy constants.

* [SKX] avx512_icmp_packed multiclass extensionRobert Khasanov2014-08-251-27/+173
| | | | | | | | | | | | | Extended avx512_icmp_packed multiclass by masking versions. Added avx512_icmp_packed_rmb multiclass for embedded broadcast versions. Added corresponding _vl multiclasses. Added encoding tests for CPCMP{EQ|GT}* instructions. Add more fields for X86VectorVTInfo. Added AVX512VLVectorVTInfo that include X86VectorVTInfo for 512/256/128-bit versions Differential Revision: http://reviews.llvm.org/D5024 llvm-svn: 216383

* Allow vectorization of division by uniform power of 2.Karthik Bhat2014-08-258-47/+103
| | | | | | | | This patch adds support to recognize division by uniform power of 2 and modifies the cost table to vectorize division by uniform power of 2 whenever possible.

| | | | llvm-svn: 216350
* TableGen: delete no-op codeDylan Noblesmith2014-08-241-7/+0
| | | | | | | | | | | | | | | | This does nothing but remove the Record from the map, and then re-add it, without actually changing it in between. The Record's Name used to be changed before re-adding it when the code was first committed in r137232, but the name-changing lines were removed in r142510, and since then this code seems to do nothing. This was also the only caller of removeClass or removeDef, so now RecordKeeper owns its Records unconditionally, and could be unique_ptr-ified. llvm-svn: 216349
