With fix: hex edited the precompiled inputs from another testcases to pass new checks. Original commit message: [Object/ELF] - Check that e_shnum is null when e_shoff is. Spec says (http://www.sco.com/developers/gabi/1998-04-29/ch4.eheader.html) : e_shnum This member holds the number of entries in the section header table. Thus the product of e_shentsize and e_shnum gives the section header table's size in bytes. If a file has no section header table, e_shnum holds the value zero.

2016-09-14[Stackmap] Added callsite counts to emitted function information.Sanjoy Das
Summary: It was previously not possible for tools to use solely the stackmap information emitted to reconstruct the return addresses of callsites in the map, which is necessary to use the information to walk a stack. This patch adds per-function callsite counts when emitting the stackmap section in order to resolve the problem. Note that this slightly alters the stackmap format, so external tools parsing these maps will need to be updated. **Problem Details:** Records only store their offset from the beginning of the function they belong to. While these records and the functions are output in program order, it is not possible to determine where the end of one function's records are without the callsite count when processing the records to compute return addresses.

2016-06-28Finish cleaning up most of the error handling in libObject’s ↵Kevin Enderby
MachOUniversalBinary and its clients to use the new llvm::Error model for error handling. Changed getAsArchive() from ErrorOr<...> to Expected<...> so now all interfaces there use the new llvm::Error model for return values. In the two places it had if (!Parent) this is actually a program error so changed from returning errorCodeToError(object_error::parse_failed) to calling report_fatal_error() with a message. In getObjectForArch() added error messages to its two llvm::Error return values instead of returning errorCodeToError(object_error::arch_not_found) with no error message. For the llvm-obdump, llvm-nm and llvm-size clients since the only binary files in Mach-O Universal Binaries that are supported are Mach-O files or archives with Mach-O objects, updated their logic to generate an error when a slice contains something like an ELF binary instead of ignoring it. And added a test case for that. The last error stuff to be cleaned up for libObject’s MachOUniversalBinary is the use of errorOrToExpected(Archive::create(ObjBuffer)) which needs Archive::create() to be changed from ErrorOr<...> to Expected<...> first, which I’ll work on next. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@274079 91177308-0d34-0410-b5e6-96231b3b80d8

The other two errors can’t be triggered if the input file is passed through sys::fs::identify_magic().

2016-06-20Add support for Darwin’s 64-bit universal files with 64-bit offsets and ↵Kevin Enderby
sizes for the objects. Darwin added support in its Xcode 8.0 tools (released in the beta) for universal files where offsets and sizes for the objects are 64-bits to allow support for objects contained in universal files to be larger then 4gb. The change is very straight forward. There is a new magic number that differs by one bit, much like the 64-bit Mach-O files. Then there is a new structure that follow the fat_header that has the same layout but with the offset and size fields using 64-bit values instead of 32-bit values. rdar://26899493 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@273207 91177308-0d34-0410-b5e6-96231b3b80d8

offsets to the archive members. Darwin added support in its Xcode 8.0 tools (released in the beta) for static library table of contents with 64-bit offsets to the archive members. The change is very straight forward. The table of contents member is named ___.SYMDEF_64 or "___.SYMDEF_64 SORTED" and same layout is used but with fields using 64 bit values instead of 32 bit values. rdar://26869808 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@273058 91177308-0d34-0410-b5e6-96231b3b80d8

2016-06-16Remove redundant -mattr options from llvm-objdump commands.Daniel Sanders
The -mattr options in these four tests have no effect on the output of llvm-objdump. In the case of the two Mips tests, removing the -mattr option left duplicate RUN lines so the duplicates have been removed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@272906 91177308-0d34-0410-b5e6-96231b3b80d8

implement this for Mips. Summary: The Mips implementation only covers the feature bits described by the ELF e_flags so far. Mips stores additional feature bits such as MSA in the .MIPS.abiflags section. Also fixed a small bug this revealed where microMIPS wouldn't add the EF_MIPS_MICROMIPS flag when using -filetype=obj.
