Introduce llvm::sys::getProcessTriple() function. In r143502, we renamed getHostTriple() to getDefaultTargetTriple() as part of work to allow the user to supply a different default target triple at configure time. This change also affected the JIT. However, it is inappropriate to use the default target triple in the JIT in most circumstances because this will not necessarily match the current architecture used by the process, leading to illegal instruction and other such errors at run time. Introduce the getProcessTriple() function for use in the JIT and its clients, and cause the JIT to use it. On architectures with a single bitness, the host and process triples are identical. On other architectures, the host triple represents the architecture of the host CPU, while the process triple represents the architecture used by the host CPU to interpret machine code within the current process. For example, when executing 32-bit code on a 64-bit Linux machine, the host triple may be 'x86_64-unknown-linux-gnu', while the process triple may be 'i386-unknown-linux-gnu'. This fixes JIT for the 32-on-64-bit (and vice versa) build on non-Apple platforms.

- Added ExecutionEngine/MCJIT tests - Added HOST_ARCH to Makefile.config.in The HOST_ARCH will be used by MCJIT tests filter, because MCJIT supported only x86 and ARM architectures now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157015 91177308-0d34-0410-b5e6-96231b3b80d8 2012-05-17 21:07:47 +00:00
