Do not define it for MIPS64 until its backend supports it. See the bug report [1] for more information.

Although this would not result in any crash or invalid behaviour as r1 is a caller saved register in AAPCS, this is unnecessary. Simply perform the division ignoring the remainder. ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/branches/release_35@216035 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@213479 91177308-0d34-0410-b5e6-96231b3b80d8
2014-07-20ARM: fix division in some casesSaleem Abdulrasool
For ARM cores that are ARMv6T2+ but not ARMv7ve or ARMv7-r and not an updated ARMv7-a that has the idiv extension (chips with clz but not idiv), an incorrect jump would be calculated due to the preference to thumb instructions over ARM. Rather than computing the target at runtime, use a jumptable instead. This trades a bit of storage for performance. The overhead is 32-bytes for each of the three routines, but avoid the calculation of the offset. Because clz was introduced in ARMv6T2 and idiv in certain versions of ARMv7, the non-clz, non-idiv case implies a target which does not support Thumb-2, and thus we cannot use Thumb on those targets (as it is unlikely that the assembly will assemble). Take the opportunity to refactor the IT block macros into assembly.h rather than redefining them in the TUs where they are used. Existing tests cover the full change already, so no new tests are added. This effectively reverts SVN r213309. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@213467 91177308-0d34-0410-b5e6-96231b3b80d8

2014-07-12[ASan] Collect unmangled names of global variables in Clang to print them in ↵Alexey Samsonov
error reports. Currently ASan instrumentation pass creates a string with global name for each instrumented global (to include global names in the error report). Global name is already mangled at this point, and we may not be able to demangle it at runtime (e.g. there is no __cxa_demangle on Android). Instead, create a string with fully qualified global name in Clang, and pass it to ASan instrumentation pass in llvm.asan.globals metadata. If there is no metadata for some global, ASan will use the original algorithm.
