* Add clang_darwin_embedded platform for embedded projectsTim Northover2013-11-151-1/+1
| | | | | | | | | | | | | | This should build a separate set of embedded runtime libraries, supporting the option product: {PIC, static} x { Hard-float, soft-float } The emphasis is on ARM platforms (Cortex-M4F, Cortex-M3, Cortex-M0) but X86 variants are also built where possible. rdar://problem/10817205 git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@194873 91177308-0d34-0410-b5e6-96231b3b80d8
* ARM: make assembly files compile Thumb2 with nop IT block.Tim Northover2013-11-118-7/+33
| | | | | | | | ARM's UAL syntax allows the same assembly file to be compiled in both ARM and Thumb mode. Conditional execution is handled by requiring the Thumb IT blocks, but essentially ignoring them when compiling for ARM. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@194429 91177308-0d34-0410-b5e6-96231b3b80d8
* Switch __ARM_ARCH_7S__ to __ARM_ARCH_EXT_IDIV__ for use of sdiv/udiv assembly.Stephen Hines2013-10-256-6/+6
| | | | | | | | | __ARM_ARCH_EXT_IDIV__ is the define that ARM is using to indicate the presence of hardware integer divide (sdiv/udiv). Previously, this code was only being invoked for processors marked 7S. We now can correctly generate hardware divides on cortex-a15 devices. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@193392 91177308-0d34-0410-b5e6-96231b3b80d8

* Remove the old, and non-functional CMake build system from CompilerRT.Chandler Carruth2012-04-041-0/+0
| | | | | | | | | I cannot build any part of this successfully on either Linux or Darwin, and the replacement is worlds simpler by requiring that this be built as a subproject of LLVM.
