[LLVMdev] LLVM new backend compiling/linking problem

[NAKAMURA Takumi]

Good afternoon, Prasanna.
M68k is interesting (to me)!

Can lib/Target/M68K be compiled from top-level?

I guess you are building on 2.7, but anyway, why do you refer to 2.5 docs?

Does your tools/llvm-config/llvm-config.in have "M68K" in @TARGETS_BUILT?
"tools" uses llvm-config to determine libraries.
$ Release+Asserts/bin/llvm-config mblaze --libs
-lLLVMMBlazeDisassembler -lLLVMMBlazeAsmParser -lLLVMMBlazeCodeGen
(snip)
-lLLVMSupport -lLLVMSystem

You may seek and refer to initial commits about recent backends in svn tree.
(eg. mblaze, nvptx)


Cheers I loved m68k, ...Takumi
