2013-02-26Unify clang/llvm attributes for asan/tsan/msan (LLVM part)Kostya Serebryany
These are two related changes (one in llvm, one in clang). LLVM: - rename address_safety => sanitize_address (the enum value is the same, so we preserve binary compatibility with old bitcode) - rename thread_safety => sanitize_thread - rename no_uninitialized_checks -> sanitize_memory CLANG: - add __attribute__((no_sanitize_address)) as a synonym for __attribute__((no_address_safety_analysis)) - add __attribute__((no_sanitize_thread)) - add __attribute__((no_sanitize_memory)) for S in address thread memory If -fsanitize=S is present and __attribute__((no_sanitize_S)) is not set llvm attribute sanitize_S git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176075 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-11Change encoding of instruction operands in bitcode binaries to be relativeJan Wen Voung
to the instruction position. The old encoding would give an absolute ID which counts up within a function, and only resets at the next function. I.e., Instead of having: ... = icmp eq i32 n-1, n-2 br i1 ..., label %bb1, label %bb2 it will now be roughly: ... = icmp eq i32 1, 2 br i1 1, label %bb1, label %bb2 This makes it so that ids remain relatively small and can be encoded in fewer bits. With this encoding, forward reference operands will be given negative-valued IDs. Use signed VBRs for the most common case of forward references, which is phi instructions. To retain backward compatibility we bump the bitcode version from 0 to 1 to distinguish between the different encodings. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165739 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-18More replacing of target-dependent intrinsics with target-indepdent Joel Jones
intrinsics. The second instruction(s) to be handled are the vector versions of count set bits (ctpop). The changes here are to clang so that it generates a target independent vector ctpop when it sees an ARM dependent vector bits set count. The changes in llvm are to match the target independent vector ctpop and in VMCore/AutoUpgrade.cpp to update any existing bc files containing ARM dependent vector pop counts with target-independent ctpops. There are also changes to an existing test case in llvm for ARM vector count instructions and to a test for the bitcode upgrade. <rdar://problem/11892519> There is deliberately no test for the change to clang, as so far as I know, no consensus has been reached regarding how to test neon instructions in clang; q.v. <rdar://problem/8762292> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160410 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-13This is one of the first steps at moving to replace target-dependent Joel Jones
intrinsics with target-indepdent intrinsics. The first instruction(s) to be handled are the vector versions of count leading zeros (ctlz). The changes here are to clang so that it generates a target independent vector ctlz when it sees an ARM dependent vector ctlz. The changes in llvm are to match the target independent vector ctlz and in VMCore/AutoUpgrade.cpp to update any existing bc files containing ARM dependent vector ctlzs with target-independent ctlzs. There are also changes to an existing test case in llvm for ARM vector count instructions and a new test for the bitcode upgrade. <rdar://problem/11831778> There is deliberately no test for the change to clang, as so far as I know, no consensus has been reached regarding how to test neon instructions in clang; q.v. <rdar://problem/8762292> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160200 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-02Make tests which first provide a negative assertion via 'not', thenChandler Carruth
a pipeline, and then a positive assertion via grep, use two RUN lines instead. Supporting these complex ideas of 'success' and 'failure' across multiple stages of a pipeline is brittle in the shell world, and would block switching to ShTest format; it only worked due to contrivances introduced by the TclTest format. Writing this as two separate RUN lines seems clearer in any event. This is another step toward completely removing TclTests from lit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159524 91177308-0d34-0410-b5e6-96231b3b80d8

2012-05-12Recommited r156374 with critical fixes in BitcodeReader/Writer:Stepan Dyatkovskiy
Ordinary patch for PR1255. Added new case-ranges orientated methods for adding/removing cases in SwitchInst. After this patch cases will internally representated as ConstantArray-s instead of ConstantInt, externally cases wrapped within the ConstantRangesSet object. Old methods of SwitchInst are also works well, but marked as deprecated. So on this stage we have no side effects except that I added support for case ranges in BitcodeReader/Writer, of course test for Bitcode is also added.

2011-03-29Add intrinsics @llvm.arm.neon.vmulls and @llvm.arm.neon.vmullu.* back. FrontendsEvan Cheng
was lowering them to sext / uxt + mul instructions. Unfortunately the optimization passes may hoist the extensions out of the loop and separate them. When that happens, the long multiplication instructions can be broken into several scalar instructions, causing significant performance issue. Note the vmla and vmls intrinsics are not added back. Frontend will codegen them as intrinsics vmull* + add / sub. Also note the isel optimizations for catching mul + sext / zext are not changed either.

2010-09-30Massive rewrite of MMX: Dale Johannesen
The x86_mmx type is used for MMX intrinsics, parameters and return values where these use MMX registers, and is also supported in load, store, and bitcast. Only the above operations generate MMX instructions, and optimizations do not operate on or produce MMX intrinsics. MMX-sized vectors <2 x i32> etc. are lowered to XMM or split into smaller pieces. Optimizations may occur on these forms and the result casted back to x86_mmx, provided the result feeds into a previous existing x86_mmx operation. The point of all this is prevent optimizations from introducing MMX operations, which is unsafe due to the EMMS problem. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@115243 91177308-0d34-0410-b5e6-96231b3b80d8
