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

Change llvm-objdump, llvm-nm and llvm-size when reporting an object file error when the object is in an archive to use something like libx.a(foo.o) as part of the error message. Also changed llvm-objdump and llvm-size to be like llvm-nm and ignore non-object files in archives and not produce any error message. To do this Archive::Child::getAsBinary() was changed from ErrorOr<...> to Expected<...> then that was threaded up to its users. Converting this interface to Expected<> from ErrorOr<> does involve touching a number of places. To contain the changes for now the use of errorToErrorCode() is still used in one place yet to be fully converted. Again there some were bugs in the existing code that did not deal with the old ErrorOr<> return values.  So now with Expected<> since they must be checked and the error handled, I added a TODO and a comments for those. llvm-svn: 269784

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] 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

Add the rest of the error checking for Mach-O dyld compact bind entry errors and test cases for each of the error checks. To do this more plumbing was needed so that the segment indexes and segment offsets can be checked. Basically what was done was the SegInfo from llvm-objdump’s MachODump.cpp was moved into libObject for Mach-O objects as BindRebaseSegInfo and it is only created when an iterator for bind or rebase entries are created. This commit really only adds the error checking and test cases for the bind table entires and the checking for the lazy bind and weak bind entries are still to be fully done as well as the rebase entires. Though some of the plumbing for those are added with this commit. Those other error checks and test cases will be added in follow on commits. Note, the two llvm_unreachable() calls should now actually be unreachable with the error checks in place and would take a logic bug in the error checking code to be reached if the segment indexes and segment offsets are used from a checked bind entry.

Change llvm-objdump, llvm-nm and llvm-size when reporting an object file error when the object is from a slice of a Mach-O Universal Binary use something like "foo.o (for architecture i386)" as part of the error message when expected. Also fixed places in these tools that were ignoring object file errors from MachOUniversalBinary::getAsObjectFile() when the code moved on to see if the slice was an archive. To do this MachOUniversalBinary::getAsObjectFile() and MachOUniversalBinary::getObjectForArch() were changed from returning ErrorOr<...> to Expected<...> then that was threaded up to its users. Converting these interfaces to Expected<> from ErrorOr<> does involve touching a number of places. To contain the changes for now the use of errorToErrorCode() is still used in two places yet to be fully converted. llvm-svn: 271332

Finish cleaning up most of the error handling in libObject’s 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. llvm-svn: 274079

General clean up of error handling in llvm-objdump to remove its use of report_fatal_error(). No real functional change with this commit. The problem with report_fatal_error() is it does not include the tool name and the file name the for which the error message was generated. Uses of report_fatal_error() were change to report_error() or error() to get a better error and to make the code smaller and cleaner. Also changed things like error(errorToErrorCode(SOrErr.takeError())) to use report_error() with a file name and the llvm::Error (as well as the ArchitectureName if available) so the error message is printed. llvm-svn: 287163

Thread Expected<...> up from createMachOObjectFile() to allow llvm-objdump to produce a real error message Produce the first specific error message for a malformed Mach-O file describing the problem instead of the generic message for object_error::parse_failed of "Invalid data was encountered while parsing the file”.  Many more good error messages will follow after this first one. This is built on Lang Hames’ great work of adding the ’Error' class for structured error handling and threading Error through MachOObjectFile construction. And making createMachOObjectFile return Expected<...> . So to to get the error to the llvm-obdump tool, I changed the stack of these methods to also return Expected<...> : object::ObjectFile::createObjectFile() object::SymbolicFile::createSymbolicFile() object::createBinary() Then finally in ParseInputMachO() in MachODump.cpp the error can be reported and the specific error message can be printed in llvm-objdump and can be seen in the existing test case for the existing malformed binary but with the updated error message. Converting these interfaces to Expected<> from ErrorOr<> does involve touching a number of places. To contain the changes for now use of errorToErrorCode() and errorOrToExpected() are used where the callers are yet to be converted. Also there some were bugs in the existing code that did not deal with the old ErrorOr<> return values. So now with Expected<> since they must be checked and the error handled, I added a TODO and a comment: “// TODO: Actually report errors helpfully” and a call something like consumeError(ObjOrErr.takeError()) so the buggy code will not crash since needed to deal with the Error. Note there is one fix also needed to lld/COFF/InputFiles.cpp that goes along with this that I will commit right after this. So expect lld not to built after this commit and before the next one. llvm-svn: 265606
