* Add Support to llvm-c-test dependanciesAmaury Sechet2016-02-051-0/+1
| | | | | | | | | | | | Summary: As per title. It is required and don't get linked in in some builds. Reviewers: chapuni, joker.eph Subscribers: llvm-commits Differential Revision: http://reviews.llvm.org/D16903 llvm-svn: 259853
* Refactor profile summary support code. NFC.Easwaran Raman2016-02-041-0/+1
| | | | | | | | | | Summary computation is not just for instrumented profiling and so I have moved the ProfileSummary class to ProfileCommon.h (named so to allow code unrelated to summary but common to instrumented and sampled profiling to be placed there) Differential Revision: http://reviews.llvm.org/D16661 llvm-svn: 259846
* Improve testing for the C APIAmaury Sechet2016-02-048-6/+488
| | | | | | | | | | | | | | | | | | | Summary: This basically add an echo test case in C. The support is limited right now, but full support would just be too much to review at once. The echo test case simply get a module as input and try to output the same exact module. This allow to check the both reading and writing API are working as expected. I want to improve this test over time to support more and more of the API, in order to improve coverage (coverage is quite poor right now). Test Plan: Run the test.

* [codeview] Wire up the .cv_inline_linetable directiveReid Kleckner2016-02-021-1/+1
| | | | | | | | This directive emits the binary annotations that describe line and code deltas in inlined call sites. Single-stepping through inlined frames in windbg now works. llvm-svn: 259535
* [llvm-nm] Simplify the code a bit. NFCI.Davide Italiano2016-02-011-6/+2
| | | | | | Fix a style violation while I'm here. llvm-svn: 259391
* [dsymutil] Skip mach-o paired relocationsFrederic Riss2016-02-011-0/+34
| | | | | | | | | Noticed while working on scattered relocations. I do not think these relocs can actually happen in the debug_info section, but if they happen the code would mishandle them. Explicitely skip them and warn if we encounter one. llvm-svn: 259341
* [dsymutil] Support scattered relocs.Frederic Riss2016-02-011-2/+15
| | | | | | | | | | Although it seems like clang will never emit scattered relocations in the debug information (at least I couldn't find a way), we have too support them for the benefit of other compilers. As clang doesn't generate them, the included testcase was produced from hacked up assembly. llvm-svn: 259339
* [dsymutil] Fix handling of common symbols.Frederic Riss2016-01-312-9/+11
| | | | | | | | | | | | | | | | | llvm-dsymutil was misinterpreting the value of common symbols as their address when it actually contains their size. This didn't impact llvm-dsymutil's ability to link the debug information for common symbols because these are always found by name and not by address. Things could however go wrong when the size of a common object matched the object file address of another symbol. Depending on the link order of the symbols the common object might incorrectly evict this other object from the address to symbol mapping, and then link the evicted symbol with a wrong binary address. Use the new ability to have symbols without an object file address to fix this. llvm-svn: 259318
* [dsymutil] Allow debug map mappings with no object file address. NFCFrederic Riss2016-01-314-21/+31
| | | | | | | | | | | This change just changes the data structure that ties symbol names, object file address and linked binary addresses to accept mappings with no object file address. Such symbol mappings are not fed into the debug map yet, so this patch is NFC. A subsequent patch will make use of this functionality for common symbols. llvm-svn: 259317
* Avoid overly large SmallPtrSet/SmallSetMatthias Braun2016-01-301-2/+2
| | | | | | | These sets perform linear searching in small mode so it is never a good idea to use SmallSize/N bigger than 32. llvm-svn: 259283
* [llvm-nm] Add a comment to explain why we initialize MC.Davide Italiano2016-01-291-0/+1
| | | | llvm-svn: 259266
* [Profiling] Add a -sparse mode to llvm-profdata mergeVedant Kumar2016-01-291-3/+7
| | | | | | | | | | Add an option to llvm-profdata merge for writing out sparse indexed profiles. These profiles omit InstrProfRecords for functions which are never executed. Differential Revision: http://reviews.llvm.org/D16727 llvm-svn: 259258
* [CodeView] Fix dumping the is_stmt bit from the line tableReid Kleckner2016-01-291-1/+1
| | | | | | Bug pointed out by George Rimar. llvm-svn: 259205
* [llvm-bcanalyzer] Dump bitcode wrapper headerAkira Hatanaka2016-01-291-1/+20
| | | | | | | | | | This patch enables llvm-bcanalyzer to print the bitcode wrapper header if the file has one, which is needed to test the changes made in r258627 (bitcode-wrapper-header-armv7m.ll is the test case for r258627). Differential Revision: http://reviews.llvm.org/D16642 llvm-svn: 259162
* Reland "[CodeView] Use assembler directives for line tables"Reid Kleckner2016-01-291-6/+5
| | | | | | | | This reverts commit r259126 and relands r259117. This time with updated library dependencies. llvm-svn: 259130
* Revert "[CodeView] Use assembler directives for line tables"Reid Kleckner2016-01-291-5/+6
| | | | | | | | | This reverts commit r259117. The LineInfo constructor is defined in the codeview library and we have to link against it now. Doing that isn't trivial, so reverting for now. llvm-svn: 259126
* Add missing raw_ostream includeReid Kleckner2016-01-291-0/+1
| | | | | | | | Prior to r259115 this was coming via LTOModule.h and MCContext.h. Apparently this target is not built by 'check'. =( llvm-svn: 259124

* [CodeView] Use assembler directives for line tablesReid Kleckner2016-01-281-6/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adds a new family of .cv_* directives to LLVM's variant of GAS syntax: - .cv_file: Similar to DWARF .file directives - .cv_loc: Similar to the DWARF .loc directive, but starts with a function id. CodeView line tables are emitted by function instead of by compilation unit, so we needed an extra field to communicate this. Rather than overloading the .loc direction further, we decided it was better to have our own directive. - .cv_stringtable: Emits the codeview string table at the current position. Currently this just contains the filenames as null-terminated strings. - .cv_filechecksums: Emits the file checksum table for all files used with .cv_file so far. There is currently no support for emitting actual checksums, just filenames. This moves the line table emission code down into the assembler. This is in preparation for implementing the inlined call site line table format. The inline line table format encoding algorithm requires knowing the absolute code offsets, so it must run after the assembler has laid out the code. David Majnemer collaborated on this patch. llvm-svn: 259117
* [llvm-nm] Remove redundant check for file validity.Davide Italiano2016-01-271-2/+0
| | | | | | | | We already perform it at the beginning of the function so we can't arrive here with an invalid object. Also, add a test so that bugs won't sneak in the future. llvm-svn: 258982

* Make more headers self-contained.Benjamin Kramer2016-01-271-0/+1
| | | | | | A lot of this comes from the new complete type requirement of DenseMap. llvm-svn: 258956
* Move SafeStack to CodeGen.Benjamin Kramer2016-01-271-0/+1
| | | | | | | It depends on the target machinery, that's not available for instrumentation passes. llvm-svn: 258942

* Remove autoconf supportChris Bieneman2016-01-2644-1083/+0
| | | | | | | | | | | | | | | | Summary: This patch is provided in preparation for removing autoconf on 1/26. The proposal to remove autoconf on 1/26 was discussed on the llvm-dev thread here: http://lists.llvm.org/pipermail/llvm-dev/2016-January/093875.html "I felt a great disturbance in the [build system], as if millions of [makefiles] suddenly cried out in terror and were suddenly silenced.

* Fix MachOObjectFile::getSymbolName() to not call report_fatal_error()Kevin Enderby2016-01-221-2/+5
| | | | | | | | | | | but to return object_error::parse_failed.  Then made the code in llvm-nm do for Mach-O files what is done in the darwin native tools which is to print "bad string index" for bad string indexes. Updated the error message in the llvm-objdump test, and added tests to show llvm-nm prints "bad string index" and a test to print the actual bad string index value which in this case is 0xfe000002 when printing the fields as raw hex. llvm-svn: 258520
* Fix MachOObjectFile::getSymbolSection() to not call report_fatal_error()Kevin Enderby2016-01-211-2/+11
| | | | | | | | | but to return object_error::parse_failed.  Then made the code in llvm-nm do for Mach-O files what is done in the darwin native tools which is to print "(?,?)" or just "s" for bad section indexes. Also added a test to show it prints the bad section index of "42" when printing the fields as raw hex. llvm-svn: 258434
* Revert obsolete llvm-link -preserve-modules option/testTeresa Johnson2016-01-211-13/+0
