* [SystemZ] Fix addcarry of addcarry of const carry (PR42606)Nikita Popov2019-07-121-2/+14
| | | | | | | | | | | | This fixes https://bugs.llvm.org/show_bug.cgi?id=42606 by extending D64213. Instead of only checking if the carry comes from a matching operation, we now check the full chain of carries. Otherwise we might custom lower the outermost addcarry, but then generically legalize an inner addcarry. Differential Revision: https://reviews.llvm.org/D64658 llvm-svn: 365949

* [SystemZ] Add support for new cpu architecture - arch13Ulrich Weigand2019-07-1219-37/+2585
| | | | | | | | | | | | | | | | | | This patch series adds support for the next-generation arch13 CPU architecture to the SystemZ backend. This includes: - Basic support for the new processor and its features. - Assembler/disassembler support for new instructions. - CodeGen for new instructions, including new LLVM intrinsics. - Scheduler description for the new processor. - Detection of arch13 as host processor. Note: No currently available Z system supports the arch13 architecture. Once new systems become available, the official system name will be added as supported -march name. llvm-svn: 365932

* [X86] Add NEG to isUseDefConvertible.Craig Topper2019-07-121-0/+5
| | | | | | | | | | | | | We can use the C flag from NEG to detect that the input was zero. Really we could probably use the Z flag too. But C matches what we'd do for usubo 0, X. Haven't found a test case for this due to the usubo formation in CGP. But I verified if I comment out the CGP code this transformation catches some of the same cases. llvm-svn: 365929

* [IndVars] Use exit count reasoning to discharge obviously untaken exitsPhilip Reames2019-07-121-17/+110
| | | | | | | | | | Continue in the spirit of D63618, and use exit count reasoning to prove away loop exits which can not be taken since the backedge taken count of the loop as a whole is provably less than the minimal BE count required to take this particular loop exit. As demonstrated in the newly added tests, this triggers in a number of cases where IndVars was previously unable to discharge obviously redundant exit tests. And some not so obvious ones.

* Support for dumping current PrettyStackTrace on SIGINFO (Ctrl-T)Jordan Rose2019-07-123-17/+119
| | | | | | | | | | | | | | | | | | | | Support SIGINFO (and SIGUSR1 for POSIX purposes) to tell what long-running jobs are doing, as inspired by BSD tools (including on macOS), by dumping the current PrettyStackTrace. This adds a new kind of signal handler for non-fatal "info" signals, similar to the "interrupt" handler that already exists for SIGINT (Ctrl-C). It then uses that handler to update a "generation count" managed by the PrettyStackTrace infrastructure, which is then checked whenever a PrettyStackTraceEntry is pushed or popped on each thread. If the generation has changed---i.e. if the user has pressed Ctrl-T---the stack trace is dumped, though unfortunately it can't include the deepest entry because that one is currently being constructed/destructed. https://reviews.llvm.org/D63750 llvm-svn: 365911
* [AMDGPU] Fix DPP combiner check for exec modificationJay Foad2019-07-124-29/+63
| | | | | | | | | | | | | | | | | | | | | | | | Summary: r363675 changed the exec modification helper function, now called execMayBeModifiedBeforeUse, so that if no UseMI is specified it checks all instructions in the basic block, even beyond the last use. That meant that the DPP combiner no longer worked in any basic block that ended with a control flow instruction, and in particular it didn't work on code sequences generated by the atomic optimizer. Fix it by reinstating the old behaviour but in a new helper function execMayBeModifiedBeforeAnyUse, and limiting the number of instructions scanned.

* [mips] Fix JmpLink to texternalsym and tglobaladdr on mcroMIPS R6Simon Atanasyan2019-07-122-1/+14
| | | | | | | | | | | | | | | | There is not match for the `MipsJmpLink texternalsym` and `MipsJmpLink tglobaladdr` patterns for microMIPS R6. As a result LLVM incorrectly selects the `JALRC16` compact 2-byte instruction which takes a target instruction address from a register only and assign `R_MIPS_32` relocation for this instruction. This relocation completely overwrites `JALRC16` and nearby instructions. This patch adds missed matching patterns, selects `BALC` instruction and assign a correct `R_MICROMIPS_PC26_S1` relocation.

* [YAMLIO] Remove trailing spaces when outputting mapsFangrui Song2019-07-121-11/+23
| | | | | | | | | | | | | | | | | | llvm::yaml::Output::paddedKey unconditionally outputs spaces, which are superfluous if the value to be dumped is a sequence or map. Change `bool NeedsNewLine` to `StringRef Padding` so that it can be overridden to `\n` if the value is a sequence or map. An empty map/sequence is special. It is printed as `{}` or `[]` without a newline, while a non-empty map/sequence follows a newline. To handle this distinction, add another variable `PaddingBeforeContainer` and does the special handling in endMapping/endSequence.
