* [Bitcode] Fix an unsigned integer overflow while parsing bitcode wrapper headerBruno Cardoso Lopes2016-05-081-1/+2
| | | | | | | | | | | | | Specially crafted bitcode wrapper headers can cause unsigned interger overflow and lead to crashes when wrapping around. Fix the offset check and avoid such scenarios. Writing a testcase for this would involve editing the binary to generate values that trigger the overflow, since this would never happen while generating the bitcode in regular compilation flows, so there's currently no feasible way add one. llvm-svn: 268881

* [ELF][MIPS] Handling 'packed' N64 ABI relocationsSimon Atanasyan2016-05-082-14/+85
| | | | | | | | | | | | | | | | | | MIPS N64 ABI packs multiple relocations into the single relocation record. In general, all up to three relocations can have arbitrary types. In fact, Clang and GCC uses only a few combinations. For now, we support two of them. That is allow to pass at least all LLVM test suite cases. <any relocation> / R_MIPS_SUB / R_MIPS_HI16 | R_MIPS_LO16 <any relocation> / R_MIPS_64 / R_MIPS_NONE The first relocation is a 'real' relocation which is calculated using the corresponding symbol's value. The second and the third relocations used to modify result of the first one: extend it to 64-bit, extract high or low part etc. For details, see part 2.9 'Relocation' at https://dmz-portal.mips.com/mw/images/8/82/007-4658-001.pdf llvm-svn: 268876
* [X86] Promote several single precision FP libcalls on WindowsDavid Majnemer2016-05-082-10/+14
| | | | | | | | | | | | A number of libcalls don't exist in any particular lib but are, instead, defined in math.h as inline functions (even in C mode!). Don't rely on their existence when lowering @llvm.{cos,sin,floor,..}.f32, promote them instead. N.B. We had logic to handle FREM but were missing out on a number of others. This change generalizes the FREM handling. llvm-svn: 268875

* [OpenMP] Check for associated statements with hasAssociatedStmt() when ↵Samuel Antao2016-05-082-1/+29
| | | | | | | | | | | | | | scanning for device code. Summary: `getAssociatedStmt()` contains an assertion that assumes the statement always exists. In device code scanning, we need to look into the associated statement therefore we check its existence. This patch replaces `getAssociatedStmt` by `hasAssociatedStmt` so that we do not trigger the assertion for directives that happen not to have an associated statement (e.g target enter/exit data).

* [ARM] Fix Scavenger assert due to underestimated stack sizeWeiming Zhao2016-05-082-5/+217
| | | | | | | | | | | | | | | | (re-apply r268810 as it exposed an uninitialized variable in ARM MFI. Patch 268868 should fix that.) Summary: Currently, when checking if a stack is "BigStack" or not, it doesn't count into spills and arguments. Therefore, LLVM won't reserve spill slot for this actually "BigStack". This may cause scavenger failure.

* [x86, BMI] add TLI hook for 'andn' and use it to simplify comparisonsSanjay Patel2016-05-075-11/+143
| | | | | | | | | | | | | | | | | | | | | For the sake of minimalism, this patch is x86 only, but I think that at least PPC, ARM, AArch64, and Sparc probably want to do this too. We might want to generalize the hook and pattern recognition for a target like PPC that has a full assortment of negated logic ops (orc, nand). Note that http://reviews.llvm.org/D18842 will cause this transform to trigger more often.
