Clang when a working GCC is available.

Now we detect this issue by compiling a simple program.  If it does not
compile, configure stops with an error suggesting the user to select a

11 years agoAllow ELF64 relocation type to be more than 8 bits.

Allow ELF64 relocation type to be more than 8 bits.

Current targets don't have more than 256 relocations so they don't hit this
limit, but ELF64 actually allows more than 8 bits for a relocation type. These
were being truncated on AArch64.

Sink a function that refers to the SelectionDAG into that library in the
one file where it is called as a static function. Nuke the declaration
and the definition in lib/CodeGen, along with the include of
SelectionDAG.h from this file.

There is no dependency edge from lib/CodeGen to
lib/CodeGen/SelectionDAG, so it isn't valid for a routine in lib/CodeGen

lib/CodeGen/SelectionDAG on lib/CodeGen. This breaks one violation of
this layering.
