[llvm-commits] CVS: llvm/tools/lli/JIT/JIT.cpp Makefile

Changes in directory llvm/tools/lli/JIT:
JIT.cpp updated: 1.10 -> 1.11
Makefile updated: 1.1 -> 1.2
---
Log message:
* If compiling on X86 or Sparc, automagically enable the JIT for that arch
* Setting ENABLE_X86_JIT or ENABLE_SPARC_JIT on the `make' command-line will
force the inclusion of that JIT on a different architecture
* If neither JIT is enabled (e.g., compiling on a different architecture), the
-march option will not be available to LLI.
* As a side effect of the $ARCH variable, the Sparc LLI can now link just a bit
faster by not including the x86 library.
