* [WebAssembly] Add first claass symbol table to wasm objectsSam Clegg2018-02-233-13/+8
| | | | | | | | | | | | | | | | | | | | This is combination of two patches by Nicholas Wilson: 1. https://reviews.llvm.org/D41954 2. https://reviews.llvm.org/D42495 Along with a few local modifications: - One change I made was to add the UNDEFINED bit to the binary format to avoid the extra byte used when writing data symbols. Although this bit is redundant for other symbols types (i.e. undefined can be implied if a function or global is a wasm import) - I prefer to be explicit and consistent and not have derived flags. - Some field renaming. - Some reverting of unrelated minor changes. - No test output differences.

* [WebAssebmly] Report undefined symbols correctly in objdumpSam Clegg2018-02-091-4/+4
| | | | | | | | | | | | | | Peviously we were reporting undefined symbol as being defined by the IMPORT sections. This change reports undefined symbols in the same that other formats do, and also removes the need to store the section with each symbol (since it can be derived from the symbol type).

* [WebAssembly] Remove debug names from symbol tableSam Clegg2018-01-171-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | Get rid of DEBUG_FUNCTION_NAME symbols. When we actually debug data, maybe we'll want somewhere to put it... but having a symbol that just stores the name of another symbol seems odd. It means you have multiple Symbols with the same name, one containing the actual function and another containing the name! Store the names in a vector on the WasmObjectFile when reading them in. Also stash them on the WasmFunctions themselves. The names are //not// "symbol names" or aliases or anything, they're just the name that a debugger should show against the function body itself. NB. The WasmObjectFile stores them so that they can be exported in the YAML losslessly, and hence the tests can be precise. Enforce that the CODE section has been read in before reading the "names" section. Requires minor adjustment to some tests. Patch by Nicholas Wilson!

* [Hexagon] New HVX target features.Sumanth Gundapaneni2017-10-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | This patch lets the llvm tools handle the new HVX target features that are added by frontend (clang). The target-features are of the form "hvx-length64b" for 64 Byte HVX mode, "hvx-length128b" for 128 Byte mode HVX. "hvx-double" is an alias to "hvx-length128b" and is soon will be deprecated. The hvx version target feature is upgated form "+hvx" to "+hvxv{version_number}. Eg: "+hvxv62" For the correct HVX code generation, the user must use the following target features. For 64B mode: "+hvxv62" "+hvx-length64b" For 128B mode: "+hvxv62" "+hvx-length128b" Clang picks a default length if none is specified. If for some reason, no hvx-length is specified to llvm, the compilation will bail out. There is a corresponding clang patch. Differential Revision: https://reviews.llvm.org/D38851 llvm-svn: 316101

| | | | | | | | | | | | | | | | | | | | | | | | | | | in the second slice of a Mach-O universal file. The code in llvm-objdump in in DisassembleMachO() was getting the default CPU then incorrectly setting into the global variable used for the -mcpu option if that was not set. This caused a second call to DisassembleMachO() to use the wrong default CPU when disassembling the next slice in a Mach-O universal file. And would result in bad disassembly and an error message about an recognized processor for the target: % llvm-objdump -d -m -arch all fat.macho-armv7s-arm64 fat.macho-armv7s-arm64 (architecture armv7s): (__TEXT,__text) section armv7: 0: 60 47 bx r12 fat.macho-armv7s-arm64 (architecture arm64): 'cortex-a7' is not a recognized processor for this target (ignoring processor) 'cortex-a7' is not a recognized processor for this target (ignoring processor) (__TEXT,__text) section ___multc3: 0: .long 0x1e620810 rdar://34439149 llvm-svn: 313921

* Add error handling to the dyld compact export entries in libObject.Kevin Enderby2017-07-2013-0/+35
| | | | | | | | | | | | | | | | | | | | | lld needs a matching change for this will be my next commit. Expect it to fail build until that matching commit is picked up by the bots. Like the changes in r296527 for dyld bind entires and the changes in r298883 for lazy bind, weak bind and rebase entries the export entries are the last of the dyld compact info to have error handling added. This follows the model of iterators that can fail that Lang Hanes designed when fixing the problem for bad archives r275316 (or r275361). So that iterating through the exports now terminates if there is an error and returns an llvm::Error with an error message in all cases for malformed input. This change provides the plumbing for the error handling, all the needed testing of error conditions and test cases for all of the unique error messages. llvm-svn: 308690

* Add the error handling for Mach-O dyld compact lazy bind, weak bind andKevin Enderby2017-03-2720-1/+58
| | | | | | | | | | | | | | | | | | | | | rebase entry errors and test cases for each of the error checks. Also verified with Nick Kledzik that a BIND_OPCODE_SET_ADDEND_SLEB opcode is legal in a lazy bind table, so code that had that as an error check was removed. With MachORebaseEntry and MachOBindEntry classes now returning an llvm::Error in all cases for malformed input the variables Malformed and logic to set use them is no longer needed and has been removed from those classes. Also in a few places, removed the redundant Done assignment to true when also calling moveToEnd() as it does that assignment. This only leaves the dyld compact export entries left to have error handling yet to be added for the dyld compact info. llvm-svn: 298883
* Add the rest of the error checking for Mach-O dyld compact bind entry errorsKevin Enderby2017-03-2019-2/+52
| | | | | | | | | | | | | | | | | | | | | | | | | and test cases for each of the error checks. To do this more plumbing was needed so that the segment indexes and segment offsets can be checked. Basically what was done was the SegInfo from llvm-objdump’s MachODump.cpp was moved into libObject for Mach-O objects as BindRebaseSegInfo and it is only created when an iterator for bind or rebase entries are created. This commit really only adds the error checking and test cases for the bind table entires and the checking for the lazy bind and weak bind entries are still to be fully done as well as the rebase entires. Though some of the plumbing for those are added with this commit. Those other error checks and test cases will be added in follow on commits. Note, the two llvm_unreachable() calls should now actually be unreachable with the error checks in place and would take a logic bug in the error checking code to be reached if the segment indexes and segment offsets are used from a checked bind entry. Comments have been added to the methods that require the arguments to have been checked prior to calling. llvm-svn: 298292
