* Add CRLF support to LineIterator.Rafael Espindola2014-11-032-0/+3
| | | | | | | The MRI scripts have to work with CRLF, and in general it is probably a good idea to support this in a core utility like LineIterator. llvm-svn: 221153
* Object, COFF: Cleanup symbol type code, improve binutils compatibilityDavid Majnemer2014-10-314-7/+7
| | | | | | | Do a better job classifying symbols. This increases the consistency between the COFF handling code and the ELF side of things. llvm-svn: 220952
* Fix getRelocationValueString to return the symbol name for EM_386.Jan Wen Voung2014-10-292-6/+6
| | | | | | | | | | | | | | Summary: This helps llvm-objdump -r to print out the symbol name along with the relocation type on x86. Adjust existing tests from checking for "Unknown" to check for the symbol now. Test Plan: Adjusted test/Object tests. Subscribers: llvm-commits Differential Revision: http://reviews.llvm.org/D5987 llvm-svn: 220866
* Handle spaces and quotes in file names in MRI scripts.Rafael Espindola2014-10-221-1/+1
| | | | llvm-svn: 220364
* MRI scripts: Add addlib support.Rafael Espindola2014-10-211-0/+17
| | | | llvm-svn: 220346
* Overwrite instead of adding to archives when creating them in mri scripts.Rafael Espindola2014-10-211-0/+18
| | | | | | | This matches the behavior of GNU ar and also makes it easier to implemnt support for the addlib command. llvm-svn: 220336
* Add support for addmod to mri scripts.Rafael Espindola2014-10-211-0/+18

| | | | | | incompatible to CRLF. llvm-svn: 219579
* llvm-ar: Start adding support for mri scripts.Rafael Espindola2014-10-105-0/+25
| | | | | | | | | | | | | | | | | | | | | | I was quiet surprised to find this feature being used. Fortunately the uses I found look fairly simple. In fact, they are just a very verbose version of the regular ar commands. Start implementing it then by parsing the script and setting the command variables as if we had a regular command line. This patch adds just enough support to create an empty archive and do a bit of error checking. In followup patches I will implement at least addmod and addlib. From the description in the manual, even the more general case should not be too hard to implement if needed. The features that don't map 1:1 to the simple command line are * Reading from multiple archives. * Creating multiple archives. llvm-svn: 219521
* Add tests for r219479.David Majnemer2014-10-102-0/+263
| | | | llvm-svn: 219480
* obj2yaml, COFF: Handle long section namesDavid Majnemer2014-10-102-0/+14
| | | | | | | | | | | | | Long section names are represented as a slash followed by a numeric ASCII string. This number is an offset into a string table. Print the appropriate entry in the string table instead of the less enlightening /4. N.B. yaml2obj already does the right thing, this test exercises both sides of the (de-)serialization. llvm-svn: 219458
* Correctly compute the size of common symbols in COFF.Rafael Espindola2014-10-081-1/+1
| | | | llvm-svn: 219324
* Print symbol sizes in this test in preparation for fixing COFF common sizes.Rafael Espindola2014-10-081-7/+7

* Nuke MCAnalysis.Sean Silva2014-09-024-251/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The code is buggy and barely tested. It is also mostly boilerplate. (This includes MCObjectDisassembler, which is the interface to that functionality) Following an IRC discussion with Jim Grosbach, it seems sensible to just nuke the whole lot of functionality, and dig it up from VCS if necessary (I hope not!). All of this stuff appears to have been added in a huge patch dump (look at the timeframe surrounding e.g. r182628) where almost every patch seemed to be untested and not reviewed before being committed. Post-review responses to the patches were never addressed. I don't think any of it would have passed pre-commit review. I doubt anyone is depending on this, since this code appears to be extremely buggy. In limited testing that Michael Spencer and I did, we couldn't find a single real-world object file that wouldn't crash the CFG reconstruction stuff. The symbolizer stuff has O(n^2) behavior and so is not much use to anyone anyway. It seemed simpler to remove them as a whole. Most of this code is boilerplate, which is the only way it was able to scrape by 60% coverage. HEADSUP: Modules folks, some files I nuked were referenced from include/llvm/module.modulemap; I just deleted the references. Hopefully that is the right fix (one was a FIXME though!). llvm-svn: 216983
* llvm-objdump: don't print relocations in non-relocatable files.Rafael Espindola2014-08-171-0/+5
| | | | | | This matches the behavior of GNU objdump. llvm-svn: 215844
* Fix an off-by-one bug in the target independent llvm-objdump.Rafael Espindola2014-08-172-0/+10
| | | | | | | | It would prevent the display of a single byte instruction before a label. Patch by Steve King! llvm-svn: 215837
* pr20589: Fix duplicated arch flag.Rafael Espindola2014-08-081-0/+10
| | | | llvm-svn: 215216
* Use "weak alias" instead of "alias weak"Rafael Espindola2014-07-301-1/+1
| | | | | | | | | | | | | | | | | | | | | Before this patch we had @a = weak global ... but @b = alias weak ... The patch changes aliases to look more like global variables. Looking at some really old code suggests that the reason was that the old bison based parser had a reduction for alias linkages and another one for global variable linkages. Putting the alias first avoided the reduce/reduce conflict. The days of the old .ll parser are long gone. The new one parses just "linkage" and a later check is responsible for deciding if a linkage is valid in a given context. llvm-svn: 214355
* Tweak llvm-nm’s -undefined-only (aka -u) printing for Mach-O filesKevin Enderby2014-07-281-0/+10
| | | | | | to just print the symbol name. So it matches darwin’s nm(1) -u option. llvm-svn: 214143
* Add an implementation for llvm-nm’s -print-file-name option (aka -o and -A).Kevin Enderby2014-07-243-0/+34
| | | | | | | | The -print-file-name option in llvm-nm is to precede each symbol with the object file it came from. While code for the parsing of this option and its aliases existed there was no code to implement it. llvm-svn: 213906
* Add printing of Mach-O stabs in llvm-nm.Kevin Enderby2014-07-172-0/+15
| | | | llvm-svn: 213327
* Add the "-x" flag to llvm-nm for Mach-O files that prints the fields of a ↵Kevin Enderby2014-07-161-0/+8
| | | | | | | | | symbol in hex. (generally use for debugging the tools).  This is same functionality as darwin’s nm(1) "-x" flag. llvm-svn: 213176
* [Mips] Support SHT_MIPS_ABIFLAGS section type flag in the llvm-readobj,Simon Atanasyan2014-07-132-1/+21

* [ELFYAML] Group ELF section type flags to target specific blocks.Simon Atanasyan2014-07-122-0/+8
| | | | | | Recognize only flags which correspond to the current target. llvm-svn: 212880
* Add the "-s" flag to llvm-nm for Mach-O files that prints symbols only inKevin Enderby2014-07-111-0/+8
| | | | | | | | | | | | | the specified section. This is same functionality as darwin’s nm(1) "-s" flag. There is one FIXME in the code and I’m all ears to anyone that can help me with that. This option takes exactly two strings and should be allowed anywhere on the command line. Such that "llvm-nm -s __TEXT __text foo.o" would work. But that does not as the CommandLine Library does not have a way to make this work as far as I can tell. For now the "-s __TEXT __text" has to be last on the command line. llvm-svn: 212842
* Changed the lvm-nm alias "-s" for -print-armap to "-M".Kevin Enderby2014-07-087-14/+14
| | | | | | | | | | This will allow the "-s" flag to implemented in the future as it is in darwin’s nm(1) to list symbols only in the specified section. Given a LGTM by Shankar Easwaran who originally implemented the support for lvm-nm’s -print-armap and archive map symbols. llvm-svn: 212576
* Add support for BSD format Archive map symbols (aka the table of contentsKevin Enderby2014-07-081-0/+6
| | | | | | from a __.SYMDEF or "__.SYMDEF SORTED" archive member). llvm-svn: 212568
* Ignore llvm.* globals.Rafael Espindola2014-07-041-0/+1
| | | | | | | It is not clear if llvm.global_ctors should or should not be in llvm.metadata, but in practice it is not and we need to ignore it for LTO. llvm-svn: 212351
* Mark intrinsic functions as llvm-specific.Rafael Espindola2014-07-041-0/+6
| | | | llvm-svn: 212347
* Don't include llvm.metadata variables in archive symbol tables.Rafael Espindola2014-07-042-0/+4
| | | | llvm-svn: 212344
* Add the -just-symbol-name (aka -j) flag to llvm-nm to just print theKevin Enderby2014-07-031-0/+8
| | | | | | | | symbol’s name. On darwin the -j flag is used (often in combinations with other flags) to produce a complete list of symbol names which than can then be reorder and used with ld(1)’s -order_file. llvm-svn: 212294
* Move test since it now depends on the x86 backend.Rafael Espindola2014-07-031-0/+0
| | | | llvm-svn: 212289
* Add support for inline asm symbols in llvm-ar.Rafael Espindola2014-07-031-0/+20
| | | | | | | This should allow llvm-ar to be used instead of gnu ar + plugin in a LTO build. I will add a release note about it once I finish a LTO bootstrap with it. llvm-svn: 212287
* Add support for inline asm symbols to IRObjectFile.Rafael Espindola2014-07-031-0/+11
| | | | | | This also enables it in llvm-nm so that it can be tested. llvm-svn: 212282
* Add the -U flag to llvm-nm as an alias to -defined-onlyKevin Enderby2014-07-031-0/+6
| | | | | | as darwin’s nm(1) uses -U for this functionality. llvm-svn: 212280
* Add the -reverse-sort flag (aka -r) to llvm-nmKevin Enderby2014-07-021-0/+8
| | | | | | which exists in other Unix nm(1)’s. llvm-svn: 212235
* Add the -arch flag support to llvm-size like what was done to llvm-nmKevin Enderby2014-07-011-2/+12
| | | | | | | | | to select the slice out of a Mach-O universal file. This also includes support for -arch all, selecting the host architecture by default from a universal file and checking if -arch is used with a standard Mach-O it matches that architecture. llvm-svn: 212108

* Change the default input for llvm-nm to be a.out instead of standard inputKevin Enderby2014-06-231-2/+10
| | | | | | | | | to match llvm-size and other UNIX systems for their nm(1). Tweak test cases that used llvm-nm with standard input to add a "-" to indicate that and add a test case to check the default of a.out for llvm-nm. llvm-svn: 211529
* Fix some double printing of filenames for archives in llvm-nm whenKevin Enderby2014-06-201-2/+4
| | | | | | | | the tool is given multiple files. Also fix the same issue with Mach-O universal files. And fix the newline spacing to separate the output in these cases. llvm-svn: 211405
* Added the -m option as an alias for -format=darwin to llvm-nm and llvm-sizeKevin Enderby2014-06-202-2/+2
| | | | | | which is what the darwin tools use for the Mach-O format output. llvm-svn: 211326

| | | | | | | | | | fat files) to print “ (for architecture XYZ)” for fat files with more than one architecture to be like what the darwin tools do for fat files. Also clean up the Mach-O printing of archive membernames in llvm-nm to use the darwin form of "libx.a(foo.o)". llvm-svn: 211316
* Teach llvm-size to know about Mach-O universal files (aka fat files) andKevin Enderby2014-06-181-0/+12
| | | | | | | | | | fat files containing archives. Also fix a bug in MachOUniversalBinary::ObjectForArch::ObjectForArch() where it needed a >= when comparing the Index with the number of objects in a fat file. As the index starts at 0. llvm-svn: 211230
* Add "-format darwin" to llvm-size to be like darwin's size(1) -m output, andKevin Enderby2014-06-173-2/+54
| | | | | | | | | | | | | | | and the -l option for the long format. Also when the object is a Mach-O file and the format is berkeley produce output like darwin’s default size(1) summary berkeley derived output. Like System V format, there are also some small changes in how and where the file names and archive member names are printed for darwin and Mach-O. Like the changes to llvm-nm these are the first steps in seeing if it is possible to make llvm-size produce the same output as darwin's size(1). llvm-svn: 211117
* Fix pr17056.Rafael Espindola2014-06-162-0/+6
| | | | | | | | | | | | | This makes llvm-nm ignore members that are not sufficiently aligned for lib/Object to handle. These archives are invalid. GNU AR is able to handle this, but in general just warns about broken archive members. We should probably start warning too, but for now just make sure llvm-nm exits with an 0. llvm-svn: 211036
* Use std::error_code instead of llvm::error_code.Rafael Espindola2014-06-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The idea of this patch is to turn llvm/Support/system_error.h into a transitional header that just brings in the erorr_code api to the llvm namespace. I will remove it shortly afterwards. The cases where the general idea needed some tweaking: * std::errc is a namespace in msvc, so we cannot use "using std::errc". I could add an #ifdef, but there were not that many uses, so I just added std:: to them in this patch. * Template specialization had to be moved to the std namespace in this patch set already. * The msvc implementation of default_error_condition doesn't seem to provide the same transformations as we need. Not too surprising since the standard doesn't actually say what "equivalent" means. I fixed the problem by keeping our old mapping and using it at error_code construction time. Despite these shortcomings I think this is still a good thing. Some reasons: * The different implementations of system_error might improve over time. * It removes 925 lines of code from llvm already. * It removes 6313 bytes from the text segment of the clang binary when it is built with gcc and 2816 bytes when building with clang and libstdc++. llvm-svn: 210687
