* Driver: Simplify a use of the path APIJustin Bogner2014-08-031-1/+1
| | | | | | | It's a bit more obvious what's going on if we use path::filename rather than decrementing an iterator here. llvm-svn: 214668

* [ASan] Use metadata to pass source-level information from Clang to ASan.Alexey Samsonov2014-08-022-25/+22
| | | | | | | | | | | | | | | | | Instead of creating global variables for source locations and global names, just create metadata nodes and strings. They will be transformed into actual globals in the instrumentation pass (if necessary). This approach is more flexible: 1) we don't have to ensure that our custom globals survive all the optimizations 2) if globals are discarded for some reason, we will simply ignore metadata for them and won't have to erase corresponding globals 3) metadata for source locations can be reused for other purposes: e.g. we may attach source location metadata to alloca instructions and provide better descriptions for stack variables in ASan error reports. No functionality change. llvm-svn: 214604
* InstrProf: Update for LLVM API changeJustin Bogner2014-08-011-7/+9
| | | | | | | | | | | | We've added support for a multiple functions with the same name in LLVM's profile data, so the lookup returning the function hash it found doesn't make sense anymore. Update to pass in the hash we expect. This also adds a test that the version 1 format is still readable, since the new API is expected to handle that. llvm-svn: 214586

* Add -fbuild-session-file as an alternative to -fbuild-session-timestampBen Langmuir2014-08-011-1/+15
| | | | | | | | Build systems tend to traffic in files and modification times, so having them touch a file at the beginning of the build can be easier than having them update the compile command they use every time they build. llvm-svn: 214577
* [Sanitizer] Introduce SanitizerMetadata class.Alexey Samsonov2014-08-017-81/+150
| | | | | | | | | | | | | | It is responsible for generating metadata consumed by sanitizer instrumentation passes in the backend. Move several methods from CodeGenModule to SanitizerMetadata. For now the class is stateless, but soon it won't be the case. Instead of creating globals providing source-level information to ASan, we will create metadata nodes/strings which will be turned into actual global variables in the backend (if needed). No functionality change. llvm-svn: 214564

* [mips] Defer va_arg expansion to the backend.Daniel Sanders2014-08-011-33/+1
| | | | | | | | | | | | | | | | | | | | | | | Summary: This patch causes clang to emit va_arg instructions to the backend instead of expanding them into an implementation itself. The backend already implements va_arg since this is necessary for NaCl so this patch is removing redundant code. Together with the llvm patch (D4556) that accounts for the effect of endianness on the expansion of va_arg, this fixes PR19612.

* [modules] Remove IRGen special case for emitting implicit special members ifRichard Smith2014-08-013-14/+10
| | | | | | | | | | | they're somehow missing a body. Looks like this was left behind when the loop was generalized, and it's not been problematic before because without modules, a used, implicit special member function declaration must be a definition. This was resulting in us trying to emit a constructor declaration rather than a definition, and producing a constructor missing its member initializers. llvm-svn: 214473

| | | | | | | | | | | | | | | of a function has a resolved exception specification, then all declarations of the function do. We should probably improve the AST representation to make this implicit (perhaps only store the exception specification on the canonical declaration), but this fixes things for now. The testcase for this (which used to assert) also exposes the actual bug I was trying to reduce here: we sometimes fail to emit the body of an imported special member function definition. Fix for that to follow. llvm-svn: 214458

* Add a state variable to the loop hint attribute.Tyler Nowicki2014-07-314-106/+124
| | | | | | | | | | This patch is necessary to support constant expressions which replaces the integer value in the loop hint attribute with an expression. The integer value was also storing the pragma’s state for options like vectorize(enable/disable) and the pragma unroll and nounroll directive. The state variable is introduced to hold the state of those options/pragmas. This moves the validation of the state (keywords) from SemaStmtAttr handler to the loop hint annotation token handler.

Adding a test for nonnull since it has little test coverage, but has truly variadic arguments. llvm-svn: 214407
