[polly] dependence on Intrinsics.gen

[Sebastian Pop]

Hi Tobi,

I am currently seeing this kind of errors when compiling polly with cmake:

In file included from ../include/llvm/IR/IntrinsicInst.h:30:0,
                 from ../tools/polly/lib/CodeGen/BlockGenerators.cpp:28:
../include/llvm/IR/Intrinsics.h:41:34: fatal error: llvm/IR/Intrinsics.gen: No such file or directory
 #include "llvm/IR/Intrinsics.gen"
                                  ^

 #include "llvm/IR/Intrinsics.gen"
                                  ^

I think LLVMPollyLib should depend on intrinsics_gen:

diff --git a/lib/CMakeLists.txt b/lib/CMakeLists.txt
index dc66491..659c4b0 100644
--- a/lib/CMakeLists.txt
+++ b/lib/CMakeLists.txt
@@ -80,7 +80,7 @@ add_polly_loadable_module(LLVMPolly
 
 if (TARGET intrinsics_gen)
   # Check if we are building as part of an LLVM build
-  add_dependencies(LLVMPolly intrinsics_gen)
+  add_dependencies(LLVMPollyLib intrinsics_gen)
 endif()
 
 target_link_libraries(LLVMPolly LLVMPollyLib)


as there is no dependence between LLVMPolly and LLVMPollyLib, and LLVMPollyLib
does contain a dependence on building the .cpp files above.

Ok to commit this change?

Thanks,
Sebastian
