* Avoid invalidating successfully loaded module filesBen Langmuir2014-06-20
| | | | | | | | | | | | | | | | | Successfully loaded module files may be referenced in other ModuleManagers, so don't invalidate them. Two related things are fixed: 1) I thought the last module in the manager was always the one that failed, but it isn't. So check explicitly against the list of vetted modules from ReadASTCore. 2) We now keep the file descriptor of pcm file open, which avoids the possibility of having two different pcms for the same module loaded when building in parallel with headers being modified during a build. <rdar://problem/16835846> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@211330 91177308-0d34-0410-b5e6-96231b3b80d8

* Frontend: Add a CC1 flag to dump module dependencies to a directoryJustin Bogner2014-06-19
| | | | | | | | | | | | | | | | | | This adds the -module-dependency-dir to clang -cc1, which specifies a directory to copy all of a module's dependencies into in a form suitable to be used as a VFS using -ivfsoverlay with the generated vfs.yaml. This is useful for crashdumps that involve modules, so that the module dependencies will be intact when a crash report script is used to reproduce a problem on another machine. We currently encode the absolute path to the dump directory, due to limitations in the VFS system. Until we can handle relative paths in the VFS, users of the VFS map may need to run a simple search and replace in the file. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@211303 91177308-0d34-0410-b5e6-96231b3b80d8

* Rewrite ARM NEON intrinsic emission completely.James Molloy2014-06-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There comes a time in the life of any amateur code generator when dumb string concatenation just won't cut it any more. For NeonEmitter.cpp, that time has come. There were a bunch of magic type codes which meant different things depending on the context. There were a bunch of special cases that really had no reason to be there but the whole thing was so creaky that removing them would cause something weird to fall over. There was a 1000 line switch statement for code generation involving string concatenation, which actually did lexical scoping to an extent (!!) with a bunch of semi-repeated cases. I tried to refactor this three times in three different ways without success. The only way forward was to rewrite the entire thing. Luckily the testing coverage on this stuff is absolutely massive, both with regression tests and the "emperor" random test case generator. The main change is that previously, in arm_neon.td a bunch of "Operation"s were defined with special names. NeonEmitter.cpp knew about these Operations and would emit code based on a huge switch. Actually this doesn't make much sense - the type information was held as strings, so type checking was impossible. Also TableGen's DAG type actually suits this sort of code generation very well (surprising that...) So now every operation is defined in terms of TableGen DAGs. There are a bunch of operators to use, including "op" (a generic unary or binary operator), "call" (to call other intrinsics) and "shuffle" (take a guess...). One of the main advantages of this apart from making it more obvious what is going on, is that we have proper type inference. This has two obvious advantages: 1) TableGen can error on bad intrinsic definitions easier, instead of just generating wrong code. 2) Calls to other intrinsics are typechecked too. So we no longer need to work out whether the thing we call needs to be the Q-lane version or the D-lane version - TableGen knows that itself! Here's an example: before: case OpAbdl: { std::string abd = MangleName("vabd", typestr, ClassS) + "(__a, __b)"; if (typestr[0] != 'U') { // vabd results are always unsigned and must be zero-extended. std::string utype = "U" + typestr.str(); s += "(" + TypeString(proto[0], typestr) + ")"; abd = "(" + TypeString('d', utype) + ")" + abd; s += Extend(utype, abd) + ";"; } else { s += Extend(typestr, abd) + ";"; } break; } after: def OP_ABDL : Op<(cast "R", (call "vmovl", (cast $p0, "U", (call "vabd", $p0, $p1))))>; As an example of what happens if you do something wrong now, here's what happens if you make $p0 unsigned before the call to "vabd" - that is, $p0 -> (cast "U", $p0): arm_neon.td:574:1: error: No compatible intrinsic found - looking up intrinsic 'vabd(uint8x8_t, int8x8_t)' Available overloads: - float64x2_t vabdq_v(float64x2_t, float64x2_t) - float64x1_t vabd_v(float64x1_t, float64x1_t) - float64_t vabdd_f64(float64_t, float64_t) - float32_t vabds_f32(float32_t, float32_t) ... snip ... This makes it seriously easy to work out what you've done wrong in fairly nasty intrinsics. As part of this I've massively beefed up the documentation in arm_neon.td too. Things still to do / on the radar: - Testcase generation. This was implemented in the previous version and not in the new one, because - Autogenerated tests are not being run. The testcase in test/ differs from the autogenerated version. - There were a whole slew of special cases in the testcase generation that just felt (and looked) like hacks. If someone really feels strongly about this, I can try and reimplement it too. - Big endian. That's coming soon and should be a very small diff on top of this one. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@211101 91177308-0d34-0410-b5e6-96231b3b80d8

* Hide the concept of diagnostic levels from lex, parse and semaAlp Toker2014-06-15
| | | | | | | | | | | | | | | | The compilation pipeline doesn't actually need to know about the high-level concept of diagnostic mappings, and hiding the final computed level presents several simplifications and other potential benefits. The only exceptions are opportunistic checks to see whether expensive code paths can be avoided for diagnostics that are guaranteed to be ignored at a certain SourceLocation. This commit formalizes that invariant by introducing and using DiagnosticsEngine::isIgnored() in place of individual level checks throughout lex, parse and sema. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@211005 91177308-0d34-0410-b5e6-96231b3b80d8

* MS ABI: Fix inheritance model calculation in CRTPDavid Majnemer2014-06-13
| | | | | | | | | | | | | | | | | CRTP-like patterns involve a class which inherits from another class using itself as a template parameter. However, the base class itself may try to create a pointer-to-member which involves the derived class. This is problematic because we may not have finished parsing the most derived classes' base specifiers yet. It turns out that MSVC simply uses the unspecified inheritance model instead of doing anything fancy.
