2013-10-30Move global FlagSfi variables to common modulePetar Jovanovic
When built as nexe, llc is configured and built for one arch only. Variables FlagSfiData, FlagSfiLoad, FlagSfiStore, FlagSfiStack, and FlagSfiBranch have to availabe for MIPS as well, so this change moves them from ARM-only code to common code.

2013-05-06[SystemZ] Update non-pic DWARF encodingsUlrich Weigand
As pointed out by Rafael Espindola, we should match the DWARF encodings produced by GCC in both pic and non-pic modes. This was not the case for the non-pic case. This patch changes all DWARF encodings to DW_EH_PE_absptr for the non-pic case, just like GCC does. The test case is updated to check for both variants. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181222 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-11[MIPS] Fix LLVM issues with recent LLVM trunk mergePetar Jovanovic
This change fixes some of the issues that came with recent merge with LLVM trunk, and it removes some workarounds that are not needed anymore in the code. In more details, it: - removes hack to set ELF::EF_MIPS_PIC flag; - checks whether __nacl_read_tp is defined in the module, as different relocation(s) is used to calculate the address; - marks Mips::JALRPseudo as indirect call in NaCl rewrite pass; - fixes incorrect merge in MipsAsmPrinter.cpp and MipsMCTargetDesc.cpp. BUG= https://code.google.com/p/nativeclient/issues/detail?id=2275 TEST= run smoke tests Review URL: https://codereview.chromium.org/13601014
2013-04-10MC: Support COFF image-relative MCSymbolRefsNico Rieck
Add support for the COFF relocation types IMAGE_REL_I386_DIR32NB and IMAGE_REL_AMD64_ADDR32NB for 32- and 64-bit respectively. These are similar to normal 4-byte relocations except that they do not include the base address of the image. Image-relative relocations are used for debug information (32-bit) and SEH unwind tables (64-bit). A new MCSymbolRef variant called 'VK_COFF_IMGREL32' is introduced to specify such relocations. For AT&T assembly, this variant can be accessed using the symbol suffix '@imgrel'. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179240 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-03Fix the fde encoding used by mips to match gas.Rafael Espindola
This finally fixes the encoding. The patch also * Removes eh-frame.ll. It was an unnecessary .ll to .o test that was checking the wrong value. * Merge fde-reloc.s and eh-frame.s into a single test, since the only difference was the run lines. * Don't blindly test the content of the entire .eh_frame section. It makes it hard to anyone actually fixing a bug and hitting a difference in a binary blob. Instead, use a CHECK for each field and document what is being checked. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178615 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-01Mips direct object exception handling regressionJack Carter
Revision 177141 caused a regression in all but mips64 little endian. That is because none of the other Mips targets had test cases checking the contents of the .eh_frame section. This patch fixes both the llvm code and adds an assembler test case to include the current 4 flavors. The test cases unfortunately rely on llvm-objdump. A preferable method would be to use a pretty printer output such as what readelf -wf <elf_file> would give. I also changed the name of the test case to correct a typo. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178506 91177308-0d34-0410-b5e6-96231b3b80d8
