* Adjust documentation for git migration.James Y Knight2019-01-2968-498/+202
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes most references to the paths: llvm.org/svn/ llvm.org/git/ llvm.org/viewvc/ github.com/llvm-mirror/ github.com/llvm-project/ reviews.llvm.org/diffusion/ to instead point to https://github.com/llvm/llvm-project. This is *not* a trivial substitution, because additionally, all the checkout instructions had to be migrated to instruct users on how to use the monorepo layout, setting LLVM_ENABLE_PROJECTS instead of checking out various projects into various subdirectories. I've attempted to not change any scripts here, only documentation. The scripts will have to be addressed separately. Additionally, I've deleted one document which appeared to be outdated and unneeded: lldb/docs/building-with-debug-llvm.txt Differential Revision: https://reviews.llvm.org/D57330 llvm-svn: 352514

* lld-link: Allow backward references between associated comdatsNico Weber2019-01-292-14/+16
| | | | | | | | | | | | | | | | | References between associated comdats are invalid per COFF spec, but the newest Windows SDK contains obj files that have these references (https://bugs.chromium.org/p/chromium/issues/detail?id=925943#c13). So add back support for them and add tests for them. The old code handled them fine. This makes lld-link match the behavior of newer link.exe versions as far as I can tell. (The behavior before this change matched the behavior of older link.exe versions.) This mostly reverts r352254. Differential Revision: https://reviews.llvm.org/D57387 llvm-svn: 352508

* [llvm-objcopy] Implement --set-section-flags.Jordan Rupprecht2019-01-298-38/+218
| | | | | | | | | | | | | | | | | Summary: --set-section-flags is used to change the section flags (e.g. SHF_ALLOC) for given sections. The flags allowed are the same from the existing --rename-section=.old=.new[,flags] feature. Additionally, make sure that --set-section-flag cannot be used with --rename-section (either the source or destination), since --rename-section accepts flags. This avoids ambiguity for something like "--rename-section=.foo=.bar,alloc --set-section-flag=.bar,code".

* [clangd] Interfaces for writing code tweaksIlya Biryukov2019-01-2915-19/+416
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: The code tweaks are an implementation of mini-refactorings exposed via the LSP code actions. They run in two stages: - Stage 1. Decides whether the action is available to the user and collects all the information required to finish the action. Should be cheap, since this will run over all the actions known to clangd on each textDocument/codeAction request from the client. - Stage 2. Uses information from stage 1 to produce the actual edits that the code action should perform. This stage can be expensive and will only run if the user chooses to perform the specified action in the UI. One unfortunate consequence of this change is increased latency of processing the textDocument/codeAction requests, which now wait for an AST. However, we cannot avoid this with what we have available in the LSP today.

| | | | | | | | | | | | | | | | | unreachable default During the lowering of a switch that would result in the generation of a jump table, a range check is performed before indexing into the jump table, for the switch value being outside the jump table range and a conditional branch is inserted to jump to the default block. In case the default block is unreachable, this conditional jump can be omitted. This patch implements omitting this conditional branch for unreachable defaults.

* [WebAssembly] Re-enable main-function signature rewritingDan Gohman2019-01-298-32/+59
| | | | | | | | | | | | | | | | Re-enable the code to rewrite main-function signatures into "int main(int argc, char *argv[])", but limited to only handling the case of "int main(void)", so that it doesn't silently strip an argument in the "int main(int argc, char *argv[], char *envp[])" case. This allows main to be called by C startup code, since WebAssembly requires caller and callee signatures to match, so it can't rely on passing main a different number of arguments than it expects.

* [IPCP] Don't crash due to arg count/type mismatch between caller/calleeBjorn Pettersson2019-01-293-0/+107
| | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This patch avoids an assert in IPConstantPropagation when there is a argument count/type mismatch between the caller and the callee. While this is actually UB on C-level (clang emits a warning), the IR verifier seems to accept it. I'm not sure what other frontends/languages might think about this, so simply bailing out to avoid hitting an assert (in CallSiteBase<>::getArgOperand or Value::doRAUW) seems like a simple solution. The problem is exposed by the fact that AbstractCallSites will look through a bitcast at the callee position of a call/invoke.

* [DebugInfo][DAG] Process FrameIndex dbg.values unconditionallyJeremy Morse2019-01-293-1/+95
| | | | | | | | | | | | | | | A FrameIndex should be valid throughout a block regardless of what instructions get selected in that block -- therefore we shouldn't harness dbg.values that refer to FrameIndexes to an SDNode. There are numerous codegen reasons why an SDNode never appears or doesn't become a location that a DBG_VALUE can refer to. None of them actually affect the variable location. Therefore, before any other tests to encode dbg_values in a SelectionDAG, identify FrameIndex operands and encode them unattached to any SDNode.

| | | | | | | | | | | | | | | | | | | | | | EK_LabelDifference32 Windows ARM64 has PIC relocation model and uses jump table kind EK_LabelDifference32. This produces jump table entry as ".word LBB123 - LJTI1_2" which represents the distance between the block and jump table. A new relocation type (IMAGE_REL_ARM64_REL32) is needed to do the fixup correctly if they are in different COFF section. This change saves the jump table to the same COFF section as the associated code. An ideal fix could be utilizing IMAGE_REL_ARM64_REL32 relocation type. Patch by Tom Tan!
