* tools: add a high level explanation for WoA EH dataSaleem Abdulrasool2014-06-07
| | | | | | | | | | | | Add a brief explanation of the data section layout for the unwind data that the Windows on ARM EH models. This is simply to provide a rough idea of the layout of the code involved in the decoding of the unwinding. Details on the involved data structures are available in the associated support header. The bulk of it is related to printing out the byte-code to help validate generation of WoA EH. No functional change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@210397 91177308-0d34-0410-b5e6-96231b3b80d8

* Add "-format darwin" to llvm-nm to be like darwin's nm(1) -m output.Kevin Enderby2014-06-05
| | | | | | | | | | | | | | | | This is a first step in seeing if it is possible to make llvm-nm produce the same output as darwin's nm(1). Darwin's default format is bsd but its -m output prints the longer Mach-O specific details. For now I added the "-format darwin" to do this (whos name may need to change in the future). As there are other Mach-O specific flags to nm(1) which I'm hoping to add some how in the future. But I wanted to see if I could get the correct output for -m flag using llvm-nm and the libObject interfaces. I got this working but would love to hear what others think about this approach to getting object/format specific details printed with llvm-nm. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@210285 91177308-0d34-0410-b5e6-96231b3b80d8

* tools: initial implementation of WoA EH decodingSaleem Abdulrasool2014-06-04
| | | | | | | | | | | | | Add support to llvm-readobj to decode Windows ARM Exception Handling data. This uses the previously added datastructures to decode the information into a format that can be used by tests. This is a necessary step to add support for emitting Windows on ARM exception handling information. A fair amount of formatting inspiration is drawn from the Win64 EH printer as well as the ARM EHABI printer. This allows for a reasonably thorough look into the encoded data. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@210192 91177308-0d34-0410-b5e6-96231b3b80d8

* Allow alias to point to an arbitrary ConstantExpr.Rafael Espindola2014-06-03
| | | | | | | | | | | | | | | | | | | | | This patch changes GlobalAlias to point to an arbitrary ConstantExpr and it is up to MC (or the system assembler) to decide if that expression is valid or not. This reduces our ability to diagnose invalid uses and how early we can spot them, but it also lets us do things like @test5 = alias inttoptr(i32 sub (i32 ptrtoint (i32* @test2 to i32), i32 ptrtoint (i32* @bar to i32)) to i32*) An important implication of this patch is that the notion of aliased global doesn't exist any more. The alias has to encode the information needed to access it in its metadata (linkage, visibility, type, etc). Another consequence to notice is that getSection has to return a "const char *". It could return a NullTerminatedStringRef if there was such a thing, but when that was proposed the decision was to just uses "const char*" for that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@210062 91177308-0d34-0410-b5e6-96231b3b80d8

* tools: avoid use of std::functionSaleem Abdulrasool2014-05-25
| | | | | | | | | | | Remove the use of the std::function and replace the capturing lambda with a non-capturing one, opting to pass the user data down to the context. This is needed as std::function is not yet available on all hosted platforms (it requires RTTI, which breaks on Windows). Thanks to Nico Rieck for pointing this out! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@209607 91177308-0d34-0410-b5e6-96231b3b80d8
* tools: split out Win64EHDumper from COFFDumperSaleem Abdulrasool2014-05-25
| | | | | | | | | | Move the implementation of the Win64 EH printer from the COFFDumper into its own class. This is in preparation for adding support to print ARM EH information. The only real change here is in printUnwindInfo where we now lambda lift the implicit this parameter for the resolveFunction. Also setup the printing to handle ARM. This now has set the stage to introduce ARM EH printing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@209606 91177308-0d34-0410-b5e6-96231b3b80d8

* tools: refactor COFFDumper symbol resolution logicSaleem Abdulrasool2014-05-25
| | | | | | | | | | Make the use of the cache more transparent to the users. There is no reason that the cached entries really need to be passed along. The overhead for doing so is minimal: a single extra parameter. This requires that some standalone functions be brought into the COFFDumper class so that they may access the cache. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@209604 91177308-0d34-0410-b5e6-96231b3b80d8

* [yaml2obj][ELF] Add an optional `Size` field to the YAML section declaration.Simon Atanasyan2014-05-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now the only method to configure ELF section's content and size is to assign a hexadecimal string to the `Content` field. Unfortunately this way is completely useless when you need to declare a really large section. To solve this problem this patch adds one more optional field `Size` to the `RawContentSection` structure. When yaml2obj generates an ELF file it uses the following algorithm: 1. If both `Content` and `Size` fields are missed create an empty section. 2. If only `Content` field is missed take section length from the `Size` field and fill the section by zero. 3. If only `Size` field is missed create a section using data from the `Content` field. 4. If both `Content` and `Size` fields are provided validate that the `Size` value is not less than size of `Content` data. Than take section length from the `Size`, fill beginning of the section by `Content` and the rest by zero. Examples -------- * Create a section 0x10000 bytes long filled by zero Name: .data Type: SHT_PROGBITS Flags: [ SHF_ALLOC ] Size: 0x10000 * Create a section 0x10000 bytes long starting from 'CA' 'FE' 'BA' 'BE' Name: .data Type: SHT_PROGBITS Flags: [ SHF_ALLOC ] Content: CAFEBABE Size: 0x10000 The patch reviewed by Michael Spencer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@208995 91177308-0d34-0410-b5e6-96231b3b80d8
* [DWARF parser] Use enums instead of bitfields in DILineInfoSpecifier.Alexey Samsonov2014-05-15
| | | | | | | | | | | | | It is more appropriate than the current situation, when one flag (AbsoluteFilePath) is relevant only if another flag is set. This refactoring would also simplify fetching the short function name (stored in DW_AT_name) instead of a linkage name returned currently.

* Fix llvm-nm to print the full 64-bit address for symbols in 64-bit object files.Kevin Enderby2014-05-09
| | | | | | | | | | | | | | | The implementation might be better to have a method is64Bit() in the class SymbolicFile instead of having the static routine isSymbolList64Bit() in llvm-nm.cpp . But this is very much in the sprit of isObject() and getNMTypeChar() in llvm-nm.cpp that has a series of if else statements based on the specific class of the SymbolicFile. I can update this if folks would like. Also the tests were updated to be explicit about checking the address for 64-bits or 32-bits from object files. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@208463 91177308-0d34-0410-b5e6-96231b3b80d8
