2015-04-14ELF: Remove redundant namespace qualifiers.Rui Ueyama
llvm-svn: 234938
2015-04-14ELF: Split HeaderChunks.h to HeaderChunks.{h,cpp}.Rui Ueyama
llvm-svn: 234932
2015-04-14Define make_dynamic_error_code(const char *).Rui Ueyama
The function took either StringRef or Twine. Since string literals are ambiguous when resolving the overloading, many code calls used this function with explicit type conversion. That led awkward code like make_dynamic_error_code(Twine("Error occurred")). This patch adds a function definition for string literals, so that you can directly call the function with literals. llvm-svn: 234841
2015-04-14ELF: Define ELF{32,64}{LE,BE} types and use them everywhere.Rui Ueyama
llvm-svn: 234823
2015-04-13[Mips] Move `MipsTargetLayout` class to the separate headerSimon Atanasyan
llvm-svn: 234727
2015-04-13[Mips] Support R_MICROMIPS_GOT_HI/LO16 and R_MICROMIPS_CALL_HI/LO16 relocationsSimon Atanasyan
llvm-svn: 234726

llvm-svn: 234725
2015-04-13[Mips] Support R_MIPS_GOT_HI16 / R_MIPS_GOT_LO16 relocations handlingSimon Atanasyan
llvm-svn: 234724
2015-04-10[Mips] Support R_MIPS_EH relocation handlingSimon Atanasyan
The patch supports just the R_MIPS_EH relocation handling and does not implement full specification of compact exception tables for MIPS ABIs. llvm-svn: 234634
2015-04-10[Mips] Replace MipsTargetHandler member function getGP() by getGPAddr()Simon Atanasyan
When we call getGP() we need in fact _gp symbol address. Let's cache its value and return it directly from the new getGPAddr() function. llvm-svn: 234632
2015-04-10[Mips] Fix typo in the commentSimon Atanasyan
llvm-svn: 234630
2015-04-06[Mips] Remove redundant non-template MipsRelocationHandler classSimon Atanasyan
llvm-svn: 234155
2015-04-06[Mips] Replace MipsRelocationHandler::readAddend() by a regular functionSimon Atanasyan
The readAddend() does not depend on MipsRelocationHandler and should not be its member function. llvm-svn: 234154
2015-03-31ELF: Remove TargetHandler::getTargetLayout.Rui Ueyama
Only MIPS used that member function, and by removing the use of the function, I removed a static_cast. Seems like it's a win. llvm-svn: 233748
2015-03-31[Mips] Use llvm::make_uniqueSimon Atanasyan
No functional changes. llvm-svn: 233727
2015-03-30[Mips] Fix writing R_MIPS_REL32 relocation addendumSimon Atanasyan
If input relocation records have RELA format while output dynamic relocations have REL format the only way to transfer a dynamic relocation addendum is to save it into the location modified by the dynamic relocation. llvm-svn: 233532
2015-03-24[Mips] Support MIPS N64 relocation record formatSimon Atanasyan
N64 ABI relocation record r_info field in fact consists of five subfields: * r_sym - symbol index * r_ssym - special symbol * r_type3 - third relocation type * r_type2 - second relocation type * r_type - first relocation type Up to three these relocations applied one by one. The first relocation uses an addendum from the relocation record. Each subsequent relocation takes as its addend the result of the previous operation. Only the final operation actually modifies the location relocated. The first relocation uses as a reference symbol specified by the `r_sym` field. The third relocation assumes NULL symbol. The patch represents these data using LLD model and takes in account additional relocation types during a relocation calculation. Additional relocations do not introduce any new relations between two atoms and just specify operations need to be done during a relocation calculation. The first relocation type (`r_type`) stored in the `Reference::_kindValue`. The rest of relocations and `r_ssym` value are stored in the new `Reference::_tag` field "as-is". I decided to do not "decode" these data on the core LLD level to prevent pollution of the core LLD model by very target specific data. Also I have to override writing of relocation records in the `RelocationTable` class to convert MIPS N64 ABI relocation information from the `Reference` class back to the ELF relocation record. http://reviews.llvm.org/D8533 llvm-svn: 233057
