[YAML] Add an optional argument `EnumMask` to the `yaml::IO::bitSetCase()`. 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. llvm-svn: 209504

[yaml2obj][ELF] Don't explicitly set `Binding` with STB_* Instead, just have 3 sub-lists, one for each of {STB_LOCAL,STB_GLOBAL,STB_WEAK}. This allows us to be a lot more explicit w.r.t. the symbol ordering in the object file, because if we allowed explicitly setting the STB_* `Binding` key for the symbol, then we might have ended up having to shuffle STB_LOCAL symbols to the front of the list, which is likely to cause confusion and potential for error. Also, this new approach is simpler ;) llvm-svn: 184506

[yaml2obj][ELF] Add an optional `Size` field to the YAML section declaration. 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. llvm-svn: 208995

[yaml2obj][ELF] ELF Relocations Support. The patch implements support for both relocation record formats: Elf_Rel and Elf_Rela. It is possible to define relocation against symbol only. Relocations against sections will be implemented later. Now yaml2obj recognizes X86_64, MIPS and Hexagon relocation types. Example of relocation section specification: Sections: - Name: .text Type: SHT_PROGBITS Content: "0000000000000000" AddressAlign: 16 Flags: [SHF_ALLOC] - Name: .rel.text Type: SHT_REL Info: .text AddressAlign: 4 Relocations: - Offset: 0x1 Symbol: glob1 Type: R_MIPS_32 - Offset: 0x2 Symbol: glob2 Type: R_MIPS_CALL16 The patch reviewed by Michael Spencer, Sean Silva, Shankar Easwaran. llvm-svn: 206017

[ELFYAML] Support mips64 relocation record format in yaml2obj/obj2yaml MIPS64 ELF file has a very specific relocation record format. Each record might specify up to three relocation operations. So the `r_info` field in fact consists of three relocation type sub-fields and optional code of "special" symbols. http://techpubs.sgi.com/library/manuals/4000/007-4658-001/pdf/007-4658-001.pdf page 40 The patch implements support of the MIPS64 relocation record format in yaml2obj/obj2yaml tools by introducing new optional Relocation fields: Type2, Type3, and SpecSym. These fields are recognized only if the object/YAML file relates to the MIPS64 target. Differential Revision: http://reviews.llvm.org/D7136 llvm-svn: 227044

[yaml2obj][ELF] Make symbols optional for relocations Some kinds of relocations do not have symbols, like R_X86_64_RELATIVE for instance. I would like to test this case in D36554 but currently can't because symbols are required by yaml2obj. The other option is using the empty symbol but that doesn't seem quite right to me. This change makes the Symbol field of Relocation optional and in the case where the user does not specify a symbol name the Symbol index is 0.

[yaml2obj] Remove --format option in favor of YAML tags Summary: Our YAML library's handling of tags isn't perfect, but it is good enough to get rid of the need for the --format argument to yaml2obj. This patch does exactly that. Instead of requiring --format, it infers the format based on the tags found in the object file. The supported tags are: !ELF !COFF !mach-o !fat-mach-o I have a corresponding patch that is quite large that fixes up all the in-tree test cases.
