llvm dev - Mar 2010 - [LLVMdev] Problem with ALWAYS_INLINE

Using GCC 3.4.6 20060404 (Red Hat 3.4.6-11) I've had this problem with
the ALWAYS_INLINE directive in SelectionDAGISel.cpp:

/arm/scratch/egrimley/llvm.svn/lib/CodeGen/SelectionDAG/SelectionDAGISel.cpp: In
function `bool CheckChildType(const unsigned char*, unsigned int&,
llvm::SDValue, const llvm::TargetLowering&, unsigned int)':
/arm/scratch/egrimley/llvm.svn/lib/CodeGen/SelectionDAG/SelectionDAGISel.cpp:1880:
sorry, unimplemented: inlining failed in call to 'bool CheckType(const
unsigned char*, unsigned int&, llvm::SDValue, const
llvm::TargetLowering&)': function body not available
/arm/scratch/egrimley/llvm.svn/lib/CodeGen/SelectionDAG/SelectionDAGISel.cpp:1894:
sorry, unimplemented: called from here
make[3]: ***
[/arm/scratch/egrimley/llvm-svn-obj/lib/CodeGen/SelectionDAG/Debug/SelectionDAGISel.o]
Error 1

I've not investigated any further as I'll probably switch to a newer GCC
quite soon anyway. As a work-around I've changed 4 to 5 in these lines
in include/llvm/Support/Compiler.h:

#if (__GNUC__ > 3 || (__GNUC__ == 3 && __GNUC_MINOR__ >= 4))
#define ALWAYS_INLINE __attribute__((always_inline))

Perhaps this change should be committed.

Sounds good, thanks for the heads up.  Committed in r97662
