Add a MachO-specific "mode" to llvm-objdump, that, if enabled, gathers additional information that are only available on MachO. - It can take FunctionStarts from a binary to find entry points more accurately. - Symbol offsets in executables are correct now. llvm-svn: 140028

Canonicalize header guards into a common format. Add header guards to files that were missing guards. Remove #endif comments as they don't seem common in LLVM (we can easily add them back if we decide they're useful) Changes made by clang-tidy with minor tweaks. llvm-svn: 215558

Add dump of Win64 EH unwind data. The new command line option -unwind-info dumps the Win64 EH unwind data to the console. This is a nice feature if you need to debug generated EH data (e.g. from LLVM). Includes a test case. Initial patch by João Matos, extensions and rework by Kai Nacke. llvm-svn: 169415

Flush out enough of llvm-objdump’s SymbolizerSymbolLookUp() for Mach-O files to get the literal string “Hello world” printed as a comment on the instruction that loads the pointer to it. For now this is just for x86_64. So for object files with relocation entries it produces things like: leaq L_.str(%rip), %rax ## literal pool for: "Hello world\n" and similar for fully linked images like executables: leaq 0x4f(%rip), %rax ## literal pool for: "Hello world\n" Also to allow testing against darwin’s otool(1), I hooked up the existing -no-show-raw-insn option to the Mach-O parser code, added the new Mach-O only -full-leading-addr option to match otool(1)'s printing of addresses and also added the new -print-imm-hex option. llvm-svn: 218423

llvm-objdump: Replace the -macho -raw option with a generic -raw-clang-ast option that works with all object container formats.

// Various helper functions.
[llvm-objdump] Call exit(1) on error, i.e. fail early. Previously we kept going on partly corrupted input, which might result in garbage being printed, or even worse, random crashes. Rafael mentioned that this is the GNU behavior as well, but after some discussion we both agreed it's probably better to emit a reasonable error message and exit. As a side-effect of this commit, now we don't rely on global state for error codes anymore. objdump was the last tool in the toolchain which needed to be converted. Hopefully the old behavior won't sneak into the tree again. llvm-svn: 244019

Object/llvm-objdump: allow dumping of mach-o exports trie MachOObjectFile in lib/Object currently has no support for parsing the rebase, binding, and export information from the LC_DYLD_INFO load command in final linked mach-o images. This patch adds support for parsing the exports trie data structure. It also adds an option to llvm-objdump to dump that export info. I did the exports parsing first because it is the hardest. The information is encoded in a trie structure, but the standard ObjectFile way to inspect content is through iterators. So I needed to make an iterator that would do a non-recursive walk through the trie and maintain the concatenation of edges needed for the current string prefix. I plan to add similar support in MachOObjectFile and llvm-objdump to parse/display the rebasing and binding info too. llvm-svn: 216808

[llvm-objdump] support -rebase option for mach-o to dump rebasing info Similar to my previous -exports-trie option, the -rebase option dumps info from the LC_DYLD_INFO load command. The rebasing info is a list of the the locations that dyld needs to adjust if a mach-o image is not loaded at its preferred address. Since ASLR is now the default, images almost never load at their preferred address, and thus need to be rebased by dyld. llvm-svn: 217709

[llvm-objdump] for mach-o add -bind, -lazy-bind, and -weak-bind options This finishes the ability of llvm-objdump to print out all information from the LC_DYLD_INFO load command. The -bind option prints out symbolic references that dyld must resolve immediately. The -lazy-bind option prints out symbolc reference that are lazily resolved on first use. The -weak-bind option prints out information about symbols which dyld must try to coalesce across images. llvm-svn: 217853
