| | | | | | | | | | | | | This makes llvm-nm ignore members that are not sufficiently aligned for lib/Object to handle. These archives are invalid. GNU AR is able to handle this, but in general just warns about broken archive members. We should probably start warning too, but for now just make sure llvm-nm exits with an 0. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211036 91177308-0d34-0410-b5e6-96231b3b80d8

* Use std::error_code instead of llvm::error_code.Rafael Espindola2014-06-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The idea of this patch is to turn llvm/Support/system_error.h into a transitional header that just brings in the erorr_code api to the llvm namespace. I will remove it shortly afterwards. The cases where the general idea needed some tweaking: * std::errc is a namespace in msvc, so we cannot use "using std::errc". I could add an #ifdef, but there were not that many uses, so I just added std:: to them in this patch. * Template specialization had to be moved to the std namespace in this patch set already. * The msvc implementation of default_error_condition doesn't seem to provide the same transformations as we need. Not too surprising since the standard doesn't actually say what "equivalent" means. I fixed the problem by keeping our old mapping and using it at error_code construction time. Despite these shortcomings I think this is still a good thing. Some reasons: * The different implementations of system_error might improve over time. * It removes 925 lines of code from llvm already. * It removes 6313 bytes from the text segment of the clang binary when it is built with gcc and 2816 bytes when building with clang and libstdc++. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@210687 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

* [YAML] Add an optional argument `EnumMask` to the `yaml::IO::bitSetCase()`.Simon Atanasyan2014-05-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some bit-set fields used in ELF file headers in fact contain two parts. The first one is a regular bit-field. The second one is an enumeraion. For example ELF header `e_flags` for MIPS target might contain the following values: Bit-set values: EF_MIPS_NOREORDER = 0x00000001 EF_MIPS_PIC = 0x00000002 EF_MIPS_CPIC = 0x00000004 EF_MIPS_ABI2 = 0x00000020 Enumeration: EF_MIPS_ARCH_32 = 0x50000000 EF_MIPS_ARCH_64 = 0x60000000 EF_MIPS_ARCH_32R2 = 0x70000000 EF_MIPS_ARCH_64R2 = 0x80000000 For printing bit-sets we use the `yaml::IO::bitSetCase()`. It does not support bit-set/enumeration combinations and prints too many flags from an enumeration part. This patch fixes this problem. New method `yaml::IO::maskedBitSetCase()` handle "enumeration" part of bitset defined by provided mask. Patch reviewed by Nick Kledzik and Sean Silva. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@209504 91177308-0d34-0410-b5e6-96231b3b80d8
* Update MachOObjectFile::getSymbolAddress so it returns UnknownAddressOrSizeKevin Enderby2014-05-20

This allows llvm-nm to print spaces instead of 0’s for the value of undefined symbols in Mach-O files.

Which is needed to keep two of the ExecutionEngine tests working for example. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@209253 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

The idea is to use it for other object formats too. I mostly wanted to do this for the general principle, but it does save a little bit on object file size. I tried this on a clang bootstrap and saved 0.54% on the sum of object file sizes (1.14 MB out of 212 MB for a release build).
