* Finish cleaning up most of the error handling in libObject’s ↵Kevin Enderby2016-06-281-6/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MachOUniversalBinary and its clients to use the new llvm::Error model for error handling. Changed getAsArchive() from ErrorOr<...> to Expected<...> so now all interfaces there use the new llvm::Error model for return values. In the two places it had if (!Parent) this is actually a program error so changed from returning errorCodeToError(object_error::parse_failed) to calling report_fatal_error() with a message. In getObjectForArch() added error messages to its two llvm::Error return values instead of returning errorCodeToError(object_error::arch_not_found) with no error message. For the llvm-obdump, llvm-nm and llvm-size clients since the only binary files in Mach-O Universal Binaries that are supported are Mach-O files or archives with Mach-O objects, updated their logic to generate an error when a slice contains something like an ELF binary instead of ignoring it. And added a test case for that. The last error stuff to be cleaned up for libObject’s MachOUniversalBinary is the use of errorOrToExpected(Archive::create(ObjBuffer)) which needs Archive::create() to be changed from ErrorOr<...> to Expected<...> first, which I’ll work on next. llvm-svn: 274079

* [ARM] Fix 28282: cost computation for constant hoistingWeiming Zhao2016-06-281-1/+1
| | | | | | | | | | | | | | | | | Summary: This fixes bug: https://llvm.org/bugs/show_bug.cgi?id=28282 Currently the cost model of constant hoisting checks the bit width of the data type of the constants. However, the actual immediate value is small enough and not need to be hoisted. This patch checks for the actual bit width needed for the constant.

* Relax the clearance calculating for breaking partial register dependency.Dehao Chen2016-06-281-6/+16
| | | | | | | | | | | | Summary: LLVM assumes that large clearance will hide the partial register spill penalty. But in our experiment, 16 clearance is too small. As the inserted XOR is normally fairly cheap, we should have a higher clearance threshold to aggressively insert XORs that is necessary to break partial register dependency.

* [YAML] Fix YAML tags appearing before the start of sequence elementsChris Bieneman2016-06-282-2/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | Our existing yaml::Output code writes tags immediately when mapTag is called, without any state handling. This results in tags on sequence elements being written before the element itself. For example, we see this: SomeArray: !elem_type - key1: 1 key2: 2 !elem_type2 - key3: 3 key4: 4 We should instead see: SomeArray: - !elem_type key1: 1 key2: 2 - !elem_type2 key3: 3 key4: 4 Our reader handles reading properly, so this bug only impacts writing yaml sequences with tagged elements. As a test for this I've modified the Mach-O yaml encoding to allways apply the !mach-o tag when encoding MachOYAML::Object entries. This results in the !mach-o tag appearing as expected in dumped fat files. llvm-svn: 274067
* [SystemZ] Use NILL instruction instead of NILF where possibleZhan Jun Liau2016-06-281-1/+32
| | | | | | | | | | | | | | | | | | | Summary: SystemZ shift instructions only use the last 6 bits of the shift amount. When the result of an AND operation is used as a shift amount, this means that we can use the NILL instruction (which operates on the last 16 bits) rather than NILF (which operates on the last 32 bits) for a 16-bit savings in instruction size.

* Use isPositionIndependent in a few more places.Rafael Espindola2016-06-285-8/+7
| | | | | | | | | I think this converts all the simple cases that really just care about the generated code being position independent or not. The remaining uses are a bit more complicated and are checking things like "is this a library or executable" or "can this symbol be preempted". llvm-svn: 274055
* Update llvm command line parser to support subcommands.Zachary Turner2016-06-281-98/+378
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This allows command line tools to use syntaxes like the following: llvm-foo.exe command1 -o1 -o2 llvm-foo.exe command2 -p1 -p2 Where command1 and command2 contain completely different sets of valid options. This is backwards compatible with previous uses of llvm cl which did not support subcommands, as any option which specifies no optional subcommand (e.g. all existing code) goes into a special "top level" subcommand that expects dashed options to appear immediately after the program name. For example, code which is subcommand unaware would generate a command line such as the following, where no subcommand is specified: llvm-foo.exe -q1 -q2 The top level subcommand can co-exist with actual subcommands, as it is implemented as an actual subcommand which is searched if no explicit subcommand is specified. So llvm-foo.exe as specified above could be written so as to support all three aforementioned command lines simultaneously. There is one additional "special" subcommand called AllSubCommands, which can be used to inject an option into every subcommand. This is useful to support things like help, so that commands such as: llvm-foo.exe --help llvm-foo.exe command1 --help llvm-foo.exe command2 --help All work and display the help for the selected subcommand without having to explicitly go and write code to handle each one separately. This patch is submitted without an example of anything actually using subcommands, but a followup patch will convert the llvm-pdbdump tool to use subcommands.

* Support arbitrary addrspace pointers in masked load/store intrinsicsArtur Pilipenko2016-06-282-10/+49
| | | | | | | | | | | | | | This is a resubmittion of 263158 change after fixing the existing problem with intrinsics mangling (see LTO and intrinsics mangling llvm-dev thread for details). This patch fixes the problem which occurs when loop-vectorize tries to use @llvm.masked.load/store intrinsic for a non-default addrspace pointer. It fails with "Calling a function with a bad signature!" assertion in CallInst constructor because it tries to pass a non-default addrspace pointer to the pointer argument which has default addrspace. The fix is to add pointer type as another overloaded type to @llvm.masked.load/store intrinsics. Reviewed By: reames Differential Revision: http://reviews.llvm.org/D17270 llvm-svn: 274043

* [X86][AVX] Peek through bitcasts to find the source of broadcasts (reapplied)Simon Pilgrim2016-06-281-3/+27
| | | | | | | | | | | | | | AVX1 can only broadcast vectors as floats/doubles, so for 256-bit vectors we insert bitcasts if we are shuffling v8i32/v4i64 types. Unfortunately the presence of these bitcasts prevents the current broadcast lowering code from peeking through cases where we have concatenated / extracted vectors to create the 256-bit vectors. This patch allows us to peek through bitcasts as long as the number of elements doesn't change (i.e. element bitwidth is the same) so the broadcast index is not affected. Note this bitcast peek is different from the stage later on which doesn't care about the type and is just trying to find a load node. As we're being more aggressive with bitcasts, we also need to ensure that the broadcast type is correctly bitcasted Differential Revision: http://reviews.llvm.org/D21660 llvm-svn: 274013

* [X86][SSE] Added support for combining target shuffles to ↵Simon Pilgrim2016-06-281-5/+101
| | | | | | | | | | | | (V)PSHUFD/VPERMILPD/VPERMILPS immediate permutes This patch allows target shuffles to be combined to single input immediate permute instructions - (V)PSHUFD/VPERMILPD/VPERMILPS - allowing more general pattern matching than what we current do and improves the likelihood of memory folding compared to existing patterns which tend to reuse the input in multiple arguments. Further permute instructions (V)PSHUFLW/(V)PSHUFHW/(V)PERMQ/(V)PERMPD may be added in the future but its proven tricky to create tests cases for them so far. (V)PSHUFLW/(V)PSHUFHW is already handled quite well in combineTargetShuffle so it may be that removing some of that code may allow us to perform more of the combining in one place without duplication.
