* Switch lowering: add heuristic for filling leaf nodes in the weight-balanced ↵Hans Wennborg2015-06-202-0/+59
| | | | | | | | | | | | | | | | | | binary search tree Sparse switches with profile info are lowered as weight-balanced BSTs. For example, if the node weights are {1,1,1,1,1,1000}, the right-most node would end up in a tree by itself, bringing it closer to the top. However, a leaf in this BST can contain up to 3 cases, and having a single case in a leaf node as in the example means the tree might become unnecessarily high. This patch adds a heauristic to the pivot selection algorithm that moves more cases into leaf nodes unless that would lower their rank. It still doesn't yield the optimal tree in every case, but I believe it's conservatibely correct. llvm-svn: 240224

| | | | | | | | | | Calling operator* on a WeakVH whose Value is null hits undefined behaviour, since we bind the value to a reference. Instead, go through `operator Value*` so that we work with the pointer itself. Found by ubsan. llvm-svn: 240214

* LowerSwitch: Avoid some undefined behaviourJustin Bogner2015-06-201-1/+2
| | | | | | | | | | | | When a case of INT64_MIN was followed by a case that was greater than zero, we were overflowing a signed integer here. Since we've sorted the cases here anyway (and thus currentValue must be greater than nextValue) it's simple enough to avoid this by using addition rather than subtraction. Found by UBSAN on existing tests. llvm-svn: 240201

* [CallGraph] Given -print-callgraph a stable printing order.Sanjoy Das2015-06-191-2/+20

* Try to fix generation of LLVMExports.cmake under Visual Studio.Dan Liew2015-06-191-1/+1
| | | | | | | | | | If LLVMDebugInfoPDB links against the DIA SDK then the exports file would contain an INTERFACE_LINK_LIBRARIES property that contained an absolute path to ``diaguids.lib`` which used a native windows path (interpreted as escape sequences when LLVMExports.cmake is imported causing ``find_package(LLVM)`` to fail) rather than the correct CMake style path. llvm-svn: 240181
* Improve error handling of getRelocationAddend.Rafael Espindola2015-06-193-13/+16
| | | | | | | | | | | | | | | | | | This patch changes getRelocationAddend to use ErrorOr and considers it an error to try to get the addend of a REL section. If, for example, a x86_64 file has a REL section, that file is corrupted and we should reject it. Using ErrorOr is not ideal since we check the section type once per relocation instead of once per section. Checking once per section would involve getRelocationAddend just asserting and callers checking the section before iterating over the relocations. In any case, this is an improvement and includes a test. llvm-svn: 240176

* [ASan] Initial support for Kernel AddressSanitizerAlexander Potapenko2015-06-191-42/+61
| | | | | | | | | This patch adds initial support for the -fsanitize=kernel-address flag to Clang. Right now it's quite restricted: only out-of-line instrumentation is supported, globals are not instrumented, some GCC kasan flags are not supported. Using this patch I am able to build and boot the KASan tree with LLVMLinux patches from github.com/ramosian-glider/kasan/tree/kasan_llvmlinux. To disable KASan instrumentation for a certain function attribute((no_sanitize("kernel-address"))) can be used. llvm-svn: 240131
* Make all temporary symbols unnamed.Rafael Espindola2015-06-193-19/+25
| | | | | | | | | | | | | | | | What this does is make all symbols that would otherwise start with a .L (or L on MachO) unnamed. Some of these symbols still show up in the symbol table, but we can just make them unnamed. In order to make sure we produce identical results when going thought assembly, all .L (not just the compiler produced ones), are now unnamed. Running llc on llvm-as.opt.bc, the peak memory usage goes from 208.24MB to 205.57MB. llvm-svn: 240130
* [ARM] Look through concat when lowering in-place shuffles (VZIP, ..)Ahmed Bougacha2015-06-191-0/+38
| | | | | | | | | | | | | | | | | | | | | | | | | Currently, we canonicalize shuffles that produce a result larger than their operands with: shuffle(concat(v1, undef), concat(v2, undef)) -> shuffle(concat(v1, v2), undef) because we can access quad vectors (see PerformVECTOR_SHUFFLECombine). This is useful in the general case, but there are special cases where native shuffles produce larger results: the two-result ops. We can look through the concat when lowering them: shuffle(concat(v1, v2), undef) -> concat(VZIP(v1, v2):0, :1) This lets us generate the native shuffles instead of scalarizing to dozens of VMOVs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | In a relocation target can take 3 basic forms * A r_value in scattered relocations. * A symbol in external relocations. * A section is non-external relocations. Have the dump reflect that. With this change we go from CHECK-NEXT: Extern: 0 CHECK-NEXT: Type: X86_64_RELOC_SUBTRACTOR (5) CHECK-NEXT: Symbol: 0x2 CHECK-NEXT: Scattered: 0 To just // CHECK-NEXT: Type: X86_64_RELOC_SUBTRACTOR (5) // CHECK-NEXT: Section: __data (2) Since the relocation is with a section, we print the seciton name and don't need to say that it is not scattered or external. Someone motivated can add further special cases for things like ARM64_RELOC_ADDEND and ARM_RELOC_PAIR. llvm-svn: 240073
