* CodeGen: Unify two implementations of canDevirtualizeMemberFunctionCall.Benjamin Kramer2013-08-253-139/+25
| | | | | | | | | They were mostly copy&paste of each other, move it to CodeGenFunction. Of course the two implementations have diverged over time; the one in CGExprCXX seems to be the more modern one so I picked that one and moved it to CGClass which feels like a better home for it. No intended functionality change. llvm-svn: 189203
* DebugInfo: Emit info for casted decls in template argsDavid Majnemer2013-08-252-2/+21
| | | | | | | | | | | | | | | | | | Summary: Previously the backend wouldn't get to see the underlying GlobalValue that corresponds to the template argument because it would be hidden by a cast at the IR level. Instead strip the pointer casts off of the value until we see the underlying GlobalValue.

* Add gcc ARM flags -munaligned-access / -mno-unaligned-accessRenato Golin2013-08-242-5/+14
| | | | | | | | | | | | | | | | clang already had a mstrict-align which mentiones "Force all memory accesses to be aligned (ARM only)". On gcc arm this is controlled by -munaligned-access / -mno-unaligned-access. Add the gcc versions to the frontend and make -mstrict-align and alias to -mno-unaligned-access and only show it in clang -cc1 -help. Since the default value for unaligned accesses / strict alignment depends on the tripple, both the enable and disable flags are added. If both are set, the no-unaligned-access is used. Patch by Jeroen Hofstee. llvm-svn: 189175
* Add the -ffixed-r9 flag for ARM.Renato Golin2013-08-242-1/+12
| | | | | | | | | | | | This patch adds the -ffixed-r9 flag to clang to instruct llvm to globally preserve the contents of r9. The flag is added to the newly created ARM specific group. While at it, also place marm / mno-thumb in that group. Patch by Jeroen Hofstee. llvm-svn: 189174

* CMake: Don't look for llvm-tblgen when building outside LLVM treeHans Wennborg2013-08-231-11/+9
| | | | | | | | | | | Previously, the CMake build would look for llvm-tblgen to determine if a directory is an LLVM build or install directory. Since we don't want to include llvm-tblgen in the install, look for llvm-config instead, and use that to find llvm-tblgen.

* [analyzer] Refactor conditional expression evaluating codePavel Labath2013-08-234-64/+100
| | | | | | | | | | | | | | | | | | | Summary: Instead of digging through the ExplodedGraph, to figure out which edge brought us here, I compute the value of conditional expression by looking at the sub-expression values. To do this, I needed to change the liveness algorithm a bit -- now, the full conditional expression also depends on all atomic sub-expressions, not only the outermost ones.

* Sema: Properly support Microsoft-mode template argumentsDavid Majnemer2013-08-233-99/+155
| | | | | | | | | | | | | | | | | | | | | | | | Summary: There were two things known to be wrong with our implementation of MSVC mode template arguments: - We didn't properly handle __uuidof/CXXUuidofExpr and skipped all type checking completely. - We didn't allow for MSVC's extension of allowing certain constant "foldable" expressions from showing up in template arguments. They allow various casts dereference and address-of operations. We can make it more general as we find further peculiarities but this is the known extent.
