* [clangd] Support configuration of inlay hints.maainSam McCall2022-01-107-18/+132
| | | | | | | | | | | | | | | | | | | | | | The idea is that the feature will always be advertised at the LSP level, but depending on config we'll return partial or no responses. We try to avoid doing the analysis for hints we're not going to return. Examples of syntax: ``` InlayHints: Enabled: No --- InlayHints: ParameterNames: No --- InlayHints: ParameterNames: Yes DeducedTypes: Yes ``` Differential Revision: https://reviews.llvm.org/D116713
* [SCEVExpander] Only create multiplication if needed.Florian Hahn2022-01-103-30/+22
| | | | | | | | | | 9345ab3a4550 updated generateOverflowCheck to skip creating checks that always evaluate to false. This in turn means that we only need to compute |Step| * Trip count if the result of the multiplication is actually used. Sink the multiplication into ComputeEndCheck, so it is only created when there's an actual check.

* [MemoryBuiltins] Remove isNoAliasFn() in favor of isNoAliasCall()Nikita Popov2022-01-107-32/+6
| | | | | | | | | | | | | | | We currently have two similar implementations of this concept: isNoAliasCall() only checks for the noalias return attribute. isNoAliasFn() also checks for allocation functions. We should switch to only checking the attribute. SLC is responsible for inferring the noalias return attribute for non-new allocation functions (with a missing case fixed in https://github.com/llvm/llvm-project/commit/348bc76e3548c52dbcd442590ca0a7f5b09b7534). For new, clang is responsible for setting the attribute, if -fno-assume-sane-operator-new is not passed. Differential Revision: https://reviews.llvm.org/D116800
* [ORC] Add helper functions for running finalize / dealloc actions.Lang Hames2022-01-106-22/+98
| | | | | | | | | | | | | | | runFinalizeActions takes an AllocActions vector and attempts to run its finalize actions. If any finalize action fails then all paired dealloc actions up to the failing pair are run, and the error(s) returned. If all finalize actions succeed then a vector containing the dealloc actions is returned. runDeallocActions takes a vector<WrapperFunctionCall> containing dealloc action calls and runs them all, returning any error(s). These helpers are intended to simplify the implementation of JITLinkMemoryManager::InFlightAlloc::finalize and JITLinkMemoryManager::deallocate overrides by taking care of execution (and potential roll-back) of allocation actions.
* [RISCV] Generalize (srl (and X, 0xffff), C) -> (srli (slli X, (XLen-16), ↵Craig Topper2022-01-0910-178/+142
| | | | | | | | | | | | | | (XLen-16) + C) optimization. This can be generalized to (srl (and X, C2), C) -> (srli (slli X, (XLen-C3), (XLen-C3) + C). Where C2 is a mask with C3 trailing ones. This can avoid constant materialization for C2. This is beneficial even when C2 can be selected to ANDI because the SLLI can become C.SLLI, but C.ANDI cannot cover all the immediates of ANDI. This also enables CSE in some cases of i8 sdiv by constant codegen.

| | | | | | | | | | | | | | | | | | | | | | indirect branch tracking(IBT) feature aiming to ensure the target address of an indirect jump/call is not tampered. When IBT is enabled, each function or target of any indirect jump/call will start with an 'endbr32/64' instruction otherwise the program will crash during execution. To build an application with CET enabled. we need to ensure: 1. build the source code with "-fcf-protection=full" 2. all the libraries linked with .o files must be CET enabled too This patch aims to enable CET for compiler-rt builtins library, we add an option "COMPILER_RT_ENABLE_CET" whose default value is OFF to enable CET for compiler-rt in building time and when this option is "ON", "-fcf-protection=full" is added to BUILTINS_CFLAG and the "endbr32/64" will be placed in the beginning of each assembly function.

| | | | | | | | | | | | | | | | | | | | | | | Fixes incomplete command names in `apropos` results. The full command names given by `apropos` have come from command name string literals given to `CommandObject` constructors. For most commands, this has been accurate, but some commands have incorrect strings. This results in `apropos` output that doesn't tell the user the full command name they might want learn more about. These strings can be fixed. There's a seperate issue that can't be fixed as easily: plugin commands. With the way they're implemented, plugin commands have to exclude the root command from their command name string. To illustrate, the `language objc` subcommand has to set its command name string to "objc", which results in apropos printing results as `objc ...` instead of `language objc ...`. To fix both of these issues, this commit changes `FindCommandsForApropos` to derive the fully qualified command name using the keys of subcommand maps.
