* [ThinLTO] Print module summary index to assemblyTeresa Johnson2018-05-261-15/+17
| | | | | | | | | | | | | | | | | | | | | Summary: Implements AsmWriter support for printing the module summary index to assembly with the format discussed in the RFC "LLVM Assembly format for ThinLTO Summary". Implements just enough of the parsing support to recognize and ignore the summary entries. As agreed in the RFC thread, this will be the behavior when assembling the IR. A follow on change will implement parsing/assembling of the summary entries for use by tools that currently build the summary index from bitcode.

| | | | | | | | Fix for PR32763 An assert that checks if a Ref was untracked fails during ThinLTO context cleanup. The issue is because lazy loading temporary nodes didn't properly track ValueAsMetadata nodes. This patch ensures that the temporary nodes are properly tracked when they're replaced with the value. llvm-svn: 310967

* Split Bitcode/ReaderWriter.h into separate reader and writer headersTeresa Johnson2016-11-111-1/+1
| | | | | | | | | | | | | | | | | | | | | Summary: Split ReaderWriter.h which contains the APIs into both the BitReader and BitWriter libraries into BitcodeReader.h and BitcodeWriter.h. This is to address Chandler's concern about sharing the same API header between multiple libraries (BitReader and BitWriter). That concern is why we create a single bitcode library in our downstream build of clang, which led to r286297 being reverted as it added a dependency that created a cycle only when there is a single bitcode library (not two as in upstream).

* IR, Bitcode: Change bitcode reader to no longer own its memory buffer.Peter Collingbourne2016-11-081-2/+2
| | | | | | | | | | | | | | | | | | Unique ownership is just one possible ownership pattern for the memory buffer underlying the bitcode reader. In practice, as this patch shows, ownership can often reside at a higher level. With the upcoming change to allow multiple modules in a single bitcode file, it will no longer be appropriate for modules to generally have unique ownership of their memory buffer. The C API exposes the ownership relation via the LLVMGetBitcodeModuleInContext and LLVMGetBitcodeModuleInContext2 functions, so we still need some way for the module to own the memory buffer. This patch does so by adding an owned memory buffer field to Module, and using it in a few other places where it is convenient. Differential Revision: https://reviews.llvm.org/D26384 llvm-svn: 286214
* Bitcode: Change reader interface to take memory buffers.Peter Collingbourne2016-11-021-27/+12
| | | | | | | | | | | | | | | | | | | As proposed on llvm-dev: http://lists.llvm.org/pipermail/llvm-dev/2016-October/106595.html This change also fixes an API oddity where BitstreamCursor::Read() would return zero for the first read past the end of the bitstream, but would report_fatal_error for subsequent reads. Now we always report_fatal_error for all reads past the end. Updated clients to check for the end of the bitstream before reading from it. I also needed to add padding to the invalid bitcode tests in test/Bitcode/. This is because the streaming interface was not checking that the file size is a multiple of 4.

* IR: Allow metadata attachments on declarations, and fix lazy loaded metadata ↵Peter Collingbourne2016-06-211-18/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | issue with globals. This change is motivated by an upcoming change to the metadata representation used for CFI. The indirect function call checker needs type information for external function declarations in order to correctly generate jump table entries for such declarations. We currently associate such type information with declarations using a global metadata node, but I plan [1] to move all such metadata to global object attachments. In bitcode, metadata attachments for function declarations appear in the global metadata block. This seems reasonable to me because I expect metadata attachments on declarations to be uncommon. In the long term I'd also expect this to be the case for CFI, because we'd want to use some specialized bitcode format for this metadata that could be read as part of the ThinLTO thin-link phase, which would mean that it would not appear in the global metadata block. To solve the lazy loaded metadata issue I was seeing with D20147, I use the same bitcode representation for metadata attachments for global variables as I do for function declarations. Since there's a use case for metadata attachments in the global metadata block, we might as well use that representation for global variables as well, at least until we have a mechanism for lazy loading global variables. In the assembly format, the metadata attachments appear after the "declare" keyword in order to avoid a parsing ambiguity.

* IR: Give 'DI' prefix to debug info metadataDuncan P. N. Exon Smith2015-04-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Finish off PR23080 by renaming the debug info IR constructs from `MD*` to `DI*`. The last of the `DIDescriptor` classes were deleted in r235356, and the last of the related typedefs removed in r235413, so this has all baked for about a week. Note: If you have out-of-tree code (like a frontend), I recommend that you get everything compiling and tests passing with the *previous* commit before updating to this one. It'll be easier to keep track of what code is using the `DIDescriptor` hierarchy and what you've already updated, and I think you're extremely unlikely to insert bugs. YMMV of course. Back to *this* commit: I did this using the rename-md-di-nodes.sh upgrade script I've attached to PR23080 (both code and testcases) and filtered through clang-format-diff.py. I edited the tests for test/Assembler/invalid-generic-debug-node-*.ll by hand since the columns were off-by-three. It should work on your out-of-tree testcases (and code, if you've followed the advice in the previous paragraph). Some of the tests are in badly named files now (e.g., test/Assembler/invalid-mdcompositetype-missing-tag.ll should be 'dicompositetype'); I'll come back and move the files in a follow-up commit. llvm-svn: 236120

* uselistorder: Remove the global bitsDuncan P. N. Exon Smith2015-04-151-2/+6
| | | | | | | | | | | | | Remove all the global bits to do with preserving use-list order by moving the `cl::opt`s to the individual tools that want them. There's a minor functionality change to `libLTO`, in that you can't send in `-preserve-bc-uselistorder=false`, but making that bit settable (if it's worth doing) should be through explicit LTO API. As a drive-by fix, I removed some includes of `UseListOrder.h` that were made unnecessary by recent commits. llvm-svn: 234973

* llvm-dis: Stop crashing when dropping debug infoDuncan P. N. Exon Smith2015-02-251-3/+10
| | | | | | | | | | | | | | | | | | Since r199356, we've printed a warning when dropping debug info. r225562 started crashing on that, since it registered a diagnostic handler that only expected errors. This fixes the handler to expect other severities. As a side effect, it now prints "error: " at the start of error messages, similar to `llvm-as`. There was a testcase for r199356, but it only really checked the assembler. Move `test/Bitcode/drop-debug-info.ll` to `test/Assembler`, and introduce `test/Bitcode/drop-debug-info.3.5.ll` (and companion `.bc`) to test the bitcode reader. Note: tools/gold/gold-plugin.cpp has an equivalent bug, but I'm not sure what the best fix is there. I'll file a PR. llvm-svn: 230416
* Use the DiagnosticHandler to print diagnostics when reading bitcode.Rafael Espindola2015-01-101-19/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The bitcode reading interface used std::error_code to report an error to the callers and it is the callers job to print diagnostics. This is not ideal for error handling or diagnostic reporting: * For error handling, all that the callers care about is 3 possibilities: * It worked * The bitcode file is corrupted/invalid. * The file is not bitcode at all. * For diagnostic, it is user friendly to include far more information about the invalid case so the user can find out what is wrong with the bitcode file. This comes up, for example, when a developer introduces a bug while extending the format. The compromise we had was to have a lot of error codes. With this patch we use the DiagnosticHandler to communicate with the human and std::error_code to communicate with the caller. This allows us to have far fewer error codes and adds the infrastructure to print better diagnostics. This is so because the diagnostics are printed when he issue is found. The code that detected the problem in alive in the stack and can pass down as much context as needed. As an example the patch updates test/Bitcode/invalid.ll. Using a DiagnosticHandler also moves the fatal/non-fatal error decision to the caller. A simple one like llvm-dis can just use fatal errors. The gold plugin needs a bit more complex treatment because of being passed non-bitcode files. An hypothetical interactive tool would make all bitcode errors non-fatal. llvm-svn: 225562

This eliminates their static initializers and, more importantly, exit-time destructors. The only behavioral change I anticipate is that tools need to initialize the PassManager before parsing the command line in order to export these options, which makes sense. Tools that already initialize the standard passes (opt/llc) don't need to do anything new. llvm-svn: 190974
