* Revert "[MachineCopyPropagation] Extend pass to do COPY source forwarding"Quentin Colombet2018-02-17118-1021/+456
| | | | | | | | | | | | | | | | | This reverts commit r323991. This commit breaks target that don't model all the register constraints in TableGen. So far the workaround was to set the hasExtraXXXRegAllocReq, but it proves that it doesn't cover all the cases. For instance, when mutating an instruction (like in the lowering of COPYs) the isRenamable flag is not properly updated. The same problem will happen when attaching machine operand from one instruction to another. Geoff Berry is working on a fix in https://reviews.llvm.org/D43042. llvm-svn: 325421
* [DAG, X86] Revert r324797, r324491, and r324359.Chandler Carruth2018-02-1718-645/+986
| | | | | | | | | | | | Sadly, r324359 caused at least PR36312. There is a patch out for review but it seems to be taking a bit and we've already had these crashers in tree for too long. We're hitting this PR in real code now and are blocked on shipping new compilers as a consequence so I'm reverting us back to green. Sorry for the churn due to the stacked changes that I had to revert. =/ llvm-svn: 325420

* [X86] Turn selects with constant condition into vector shuffles during DAG ↵Craig Topper2018-02-174-47/+61
| | | | | | | | | | | | | | | | | | | | | | | combine Summary: Currently we convert to shuffles during lowering. This moves it to DAG combine so hopefully we can get it done before type legalization has to extend the condition. I believe in some cases we're creating SHRUNKBLENDs that end up with constant conditions because we see the extended on the condition and think its a dynamic selelect before DAG combine gets a chance to constant fold the extend. We could add combines to turn SHRUNKBLENDs with constant condition back to vselect. But it seemed like it might be better to just send them to shuffles as early as possible so they never get a chance to become SHRUNKBLENDs. This the reason some tests went from blends controlled by a constant pool load to just move. Some of the constant pool entries changed because the sign_extend introduced by type legalization turned undef elements in select condition into 0s. While the select->shuffle used -1 in the shuffle mask. So now the shuffle lowering can do what it wants with them. I'll remove the lowering code as a follow up. We might be able to simplify some of the pre-checks for SHRUNKBLEND as the FIXME there says.

* Remove "--full-shutdown" and instead use an environment variable LLD_IN_TEST.Rui Ueyama2018-02-168-21/+22
| | | | | | | | | | | | | | | | | We are running lld tests with "--full-shutdown" option because we don't want to call _exit() in lld if it is running tests. Regular shutdown is needed for leak sanitizer. This patch changes the way how we tell lld that it is running tests. Now "--full-shutdown" is removed, and LLD_IN_TEST environment variable is used instead. This patch enables full shutdown on all ports, e.g. ELF, COFF and wasm. Previously, we enabled it only for ELF.

* [ThinLTO] Allow indexing to request backend to ignore the moduleVitaly Buka2018-02-168-13/+100
| | | | | | | | | | | | | | | | | | Summary: Gold plugin does not add pass to ThinLTO modules without useful symbols. In this case ThinLTO can't create corresponding index file and some features, like CFI, cannot be processes by backed correctly without index. Given that we don't need the backed output we can request it to avoid processing the module. This is implemented by this patch using new "SkipModuleByDistributedBackend" flag.

When hovering a variable, function, method or namespace, clangd will return a text containing the declaration's scope, as well as the declaration of the hovered entity. For example, for a variable: Declared in class Foo::Bar int hello = 2 For macros, the macro definition is returned. This patch doesn't include: - markdown support (the client I use doesn't support it yet) - range support (optional in the Hover response) - comments associated to variables/functions/classes They are kept as future work to keep this patch simpler. I added tests in XRefsTests.cpp. hover.test contains one simple smoketest to make sure the feature works from a black box perspective.

* Fix emission of PDB string table.Zachary Turner2018-02-169-188/+245
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This was originally reported as a bug with the symptom being "cvdump crashes when printing an LLD-linked PDB that has an S_FILESTATIC record in it". After some additional investigation, I determined that this was a symptom of a larger problem, and in fact the real problem was in the way we emitted the global PDB string table. As evidence of this, you can take any lld-generated PDB, run cvdump -stringtable on it, and it would return no results. My hypothesis was that cvdump could not *find* the string table to begin with. Normally it would do this by looking in the "named stream map", finding the string /names, and using its value as the stream index. If this lookup fails, then cvdump would fail to load the string table. To test this hypothesis, I looked at the name stream map generated by a link.exe PDB, and I emitted exactly those bytes into an LLD-generated PDB. Suddenly, cvdump could read our string table! This code has always been hacky and we knew there was something we didn't understand. After all, there were some comments to the effect of "we have to emit strings in a specific order, otherwise things don't work". The key to fixing this was finally understanding this. The way it works is that it makes use of a generic serializable hash map that maps integers to other integers. In this case, the "key" is the offset into a buffer, and the value is the stream number. If you index into the buffer at the offset specified by a given key, you find the name. The underlying cause of all these problems is that we were using the identity function for the hash. i.e. if a string's offset in the buffer was 12, the hash value was 12. Instead, we need to hash the string *at that offset*. There is an additional catch, in that we have to compute the hash as a uint32 and then truncate it to uint16. Making this work is a little bit annoying, because we use the same hash table in other places as well, and normally just using the identity function for the hash function is actually what's desired. I'm not totally happy with the template goo I came up with, but it works in any case. The reason we never found this bug through our own testing is because we were building a /parallel/ hash table (in the form of an llvm::StringMap<>) and doing all of our lookups and "real" hash table work against that. I deleted all of that code and now everything goes through the real hash table. Then, to test it, I added a unit test which adds 7 strings and queries the associated values. I test every possible insertion order permutation of these 7 strings, to verify that it really does work as expected. Differential Revision: https://reviews.llvm.org/D43326 llvm-svn: 325386
