* Revert r185872 - "Stop emitting weak symbols into the "coal" sections"Alexander Potapenko2013-07-093-83/+10
| | | | | | | | | | | | | This patch broke `make check-asan` on Mac, causing ld warnings like the following one: ld: warning: direct access in __GLOBAL__I_a to global weak symbol ___asan_mapping_scale means the weak symbol cannot be overridden at runtime. This was likely caused by different translation units being compiled with different visibility settings. The resulting test binaries crashed with incorrect ASan warnings. llvm-svn: 185923

* [SystemZ] Use MVC for simple load/store pairsRichard Sandiford2013-07-096-2/+506
| | | | | | | | | | | | Look for patterns of the form (store (load ...), ...) in which the two locations are known not to partially overlap. (Identical locations are OK.) These sequences are better implemented by MVC unless either the load or the store could use RELATIVE LONG instructions. The testcase showed that we weren't using LHRL and LGHRL for extload16, only sextloadi16. The patch fixes that too. llvm-svn: 185919
* [SystemZ] Use "STC;MVC" for memsetRichard Sandiford2013-07-097-0/+1171
| | | | | | | | | | | | Use "STC;MVC" for memsets that are too big for two STCs or MV...Is yet small enough for a single MVC. As with memcpy, I'm leaving longer cases till later. The number of tests might seem excessive, but f33 & f34 from memset-04.ll failed the first cut because I'd not added the "?:" on the calculation of Size1. llvm-svn: 185918

* InstCombine: variations on 0xffffffff - x >= 4David Majnemer2013-07-092-0/+30
| | | | | | | | | | The following transforms are valid if -C is a power of 2: (icmp ugt (xor X, C), ~C) -> (icmp ult X, C) (icmp ult (xor X, C), -C) -> (icmp uge X, C) These are nice, they get rid of the xor. llvm-svn: 185915
* Fix alignment of closing brace in braced initializers.Daniel Jasper2013-07-095-33/+43
| | | | | | | | | | | | | | | | | | | | | | Before: someFunction(OtherParam, BracedList{ // comment 1 (Forcing intersting break) param1, param2, // comment 2 param3, param4 }); After: someFunction(OtherParam, BracedList{ // comment 1 (Forcing intersting break) param1, param2, // comment 2 param3, param4 }); To do so, the UnwrappedLineParser now stores the information about the kind of brace in the FormatToken. llvm-svn: 185914

* [PowerPC] Support .llong and fix .wordUlrich Weigand2013-07-094-2/+60
| | | | | | | | This adds support for the .llong PowerPC-specifc assembler directive. In doing so, I notices that .word is currently incorrect: it is supposed to define a 2-byte data element, not a 4-byte one. llvm-svn: 185911

* Format overloaded operators like other functions.Daniel Jasper2013-07-093-5/+15
| | | | | | | | | | | | | | This fixes llvm.org/PR16328 (at least partially). Before: SomeLoooooooooooooooooooooooooooooogType operator<<( const SomeLooooooooogType &a, const SomeLooooooooogType &b); After: SomeLoooooooooooooooooooooooooooooogType operator<<(const SomeLooooooooogType &a, const SomeLooooooooogType &b); llvm-svn: 185908
* PPC: Allocate RS spill slot for unaligned i64 load/storeHal Finkel2013-07-092-2/+152
| | | | | | | | | | | | | | | | | | | This fixes another bug found by llvm-stress! If we happen to be doing an i64 load or store into a stack slot that has less than a 4-byte alignment, then the frame-index elimination may need to use an indexed load or store instruction (because the offset may not be a multiple of 4, a requirement of the STD/LD instructions). The extra register needed to hold the offset comes from the register scavenger, and it is possible that the scavenger will need to use an emergency spill slot. As a result, we need to make sure that a spill slot is allocated when doing an i64 load/store into a less-than-4-byte-aligned stack slot. Because test cases for things like this tend to be fairly fragile, I've concatenated a few small bugpoint-reduced test cases together to form the regression test. llvm-svn: 185907

* Compute the size of an archive member in the constructor.Rafael Espindola2013-07-092-16/+15

* [PECOFF][Writer] Compute the size of a chunk each time it's added rather ↵Rui Ueyama2013-07-091-42/+34
| | | | | | | | | | | | | | | than all at once. Contents of ".reloc" section depends on the addresses of other sections, so the section cannot be created until all the other sections are created and get their memory addresses (RVAs). That means that computation of section size needs to be at least two pass. Techynically there's no reason to compute it all at once, but instead we can compute the address of a section as added to the output file. Doing so helps us to create ".reloc" section. llvm-svn: 185902

* X86 fast-isel: Avoid explicit AH subreg reference for [SU]Rem.Jim Grosbach2013-07-091-4/+31
| | | | | | | | | | | | | Explicit references to %AH for an i8 remainder instruction can lead to references to %AH in a REX prefixed instruction, which causes things to blow up. Do the same thing in FastISel as we do for DAG isel and instead shift %AX right by 8 bits and then extract the 8-bit subreg from that result. rdar://14203849 http://llvm.org/bugs/show_bug.cgi?id=16105 llvm-svn: 185899

| | | | | | | | | | | | | | - Test verifies LLDB's handling of inferiors with threads that: hit breakpoints, modfiy variables that have watchpoints set, generate user signals, and crash. - Add a few "stress tests" (with ~100 threads) -- run these with "-l" dotest.py flag. - Fix stop_reason_to_str helper in lldbutil to handle eStopReasonThreadExited. - Add sort_stopped_threads helper to lldbutil to separate thread lists based on stop reason.

* Don't run internalize if we're outputing bit-code and not an object file.Bill Wendling2013-07-081-2/+4
| | | | | | | | | | The problem with running internalize before we're ready to output an object file is that it may change a 'weak' symbol into an internal one, but that symbol could be needed by an external object file --- e.g. with arclite. <rdar://problem/14334895> llvm-svn: 185882
* Attempt typo correction for function calls with the wrong number of arguments.Kaelyn Uhrain2013-07-086-7/+157
| | | | | | | | | | | | | | | Combined with typo correction's new ability to apply global/absolute nested name specifiers to possible corrections, cases such as in PR12287 where the desired function is being shadowed by a lexically closer function with the same name but a different number of parameters will now include a FixIt. On a side note, since the test for this change caused test/SemaCXX/typo-correction.cpp to exceed the typo correction limit for a single file, I've included a test case for exceeding the limit and added some comments to both the original and part two of typo-correction.cpp warning future editors of the files about the limit. llvm-svn: 185881

* Added a way to extract the module specifications from a file. A module ↵Greg Clayton2013-07-0820-106/+842
| | | | | | | | | | | | | specification is information that is required to describe a module (executable, shared library, object file, ect). This information includes host path, platform path (remote path), symbol file path, UUID, object name (for objects in .a files for example you could have an object name of "foo.o"), and target triple. Module specification can be used to create a module, or used to add a module to a target. A list of module specifications can be used to enumerate objects in container objects (like universal mach files and BSD archive files). There are two new classes: lldb::SBModuleSpec lldb::SBModuleSpecList The SBModuleSpec wraps up a lldb_private::ModuleSpec, and SBModuleSpecList wraps up a lldb_private::ModuleSpecList. llvm-svn: 185877
