* TableGen: Allow NAME in template arguments in defm in multiclassNicolai Haehnle2018-03-053-0/+85
| | | | | | | | | | | | | | | | | | | | Summary: NAME has already worked for def in a multiclass, since the (protoype) record including its NAME variable is created before parsing the superclasses. Since defm's do not have an associated single record, support for NAME has to be implemented differently here.

* TableGen: Use DefInit::getDef() instead of the type's getRecord()Nicolai Haehnle2018-03-051-14/+11
| | | | | | | | | | | The former simply makes more sense: we want to access the data here in the backend, not information about the type. More importantly, removing users of RecordRecTy::getRecord() allows us more freedom to refactor the frontend. Change-Id: Iee8905fd22cdb9b11c42ca03246c03d8fe4dd77f llvm-svn: 326699

* [ARM][Asm] VMOVSRR and VMOVRRS need sequential S registersOliver Stannard2018-03-052-0/+24
| | | | | | | | | | These instructions require that the two S registers are adjacent (but not the R registers), because only the first register is included in the encoding, but we were not checking this in the assembler. Differential revision: https://reviews.llvm.org/D44084 llvm-svn: 326696

* [x86][CET] Introduce _get_ssp, _inc_ssp intrinsicsAlexander Ivchenko2018-03-052-2/+51
| | | | | | | | | | | | | | | | | | | | | | | | | | Summary: The _get_ssp intrinsic can be used to retrieve the shadow stack pointer, independent of the current arch -- in contract with the rdsspd and the rdsspq intrinsics. Also, this intrinsic returns zero on CPUs which don't support CET. The rdssp[d|q] instruction is decoded as nop, essentially just returning the input operand, which is zero. Example result of compilation: ``` xorl %eax, %eax movl %eax, %ecx rdsspq %rcx # NOP when CET is not supported movq %rcx, %rax # return zero ``` Reviewers: craig.topper Subscribers: cfe-commits Differential Revision: https://reviews.llvm.org/D43814 llvm-svn: 326689

* [test] Add dotest wrapperJonas Devlieghere2018-03-052-2/+31
| | | | | | | | | | | | | | | | | | | | | This adds a wrapper around dotest, similar to llvm-lit in llvm. The wrapper is created in the binary directory, next to LLDB and allows you to invoke dotest without having to pass any of the configuration arguments yourself. I think this could also be useful for re-running a particular test case when it fails, as an alternative to "Command Invoked". The motivation for this is that I'd like to replace the driver part of dotest with lit. As a first step, I'd like to have lit invoke dotest, which would just run the complete test suite, completely identical to what the CMake target does today. Once this is in place, we can have lit run dotest for the different test directories, and ultimately once per python file. Along the way we can strip out driver functionality from dotest where appropriate. https://reviews.llvm.org/D44002 llvm-svn: 326687

* [Bash-autocompletion] Pass all flags in shell command-line to ClangYuka Takahashi2018-03-055-78/+75
| | | | | | | | | | | | | | | | | | | | Previously, we passed "#" to --autocomplete to indicate to enable cc1 flags. For example, when -cc1 or -Xclang was passed to bash, bash executed `clang --autocomplete=#-<flag they want to complete>`. However, this was not a good implementation because it depends -Xclang and -cc1 parsing to shell. So I changed this to pass all flags shell has, so that Clang can handle them internally. I had to change many testcases because API spec changed quite a lot.

| | | | | | | | fix a crash if we are storing a bitcast of a constant. Loading a constant into a k-register in AVX512 requires a bitcast from a scalar constant. In the test case here we have a k-register store that gets split into multiple parts of KNL. MergeConsecutiveStores sees each of these pieces as a consecutive store and looks through the bitcast to find the underly scalar constant. But when we went to create the combined store we didn't look through the same bitcast. llvm-svn: 326677

The split blocks must include not only the call instruction itself, but also (optional) `bitcast` and `return` instructions that follow it. Clone `bitcast` and `ret`, place them into the split blocks, and remove the tail block when done.

* [ScopInfo] Do not use the set dimension ids to carry loop informationTobias Grosser2018-03-035-48/+22
| | | | | | | | | | | | | | isl does not guarantee that set dimension ids will be preserved, so using them to carry information is not a good idea. Furthermore, the loop information can be derived without problem from the statement itself. As this even requires less code than propagating loop information on set dimension ids, starting from this commit we just derive the loop information in collectSurroundingLoops directly from the IR. Interestingly this also results in a couple of isl sets to take a simpler representation. llvm-svn: 326664
