llc only supports one input file #36

Open otsmr opened 11 months ago

otsmr commented 11 months ago

When the target library is compiled to a static library with the following CMAKE options:

add_library(testbase STATIC ${SOURCE_FILES})
llvmir_attach_bc_target(testbase_bc testbase)
llvmir_attach_opt_pass_target(testbase_opt testbase_bc -load-pass-plugin=${LLVM_PASS_CTRACE} -passes=ctrace)
llvmir_attach_obj_target(testbase_obj testbase_opt)
llvmir_attach_library(testbase_instrumented testbase_obj STATIC)

I got the following error message:

FAILED: llvm-ir/testbase_obj/testbase_obj.o /[...]/build/llvm-ir/testbase_obj/testbase_obj.o

The problem is that LLC only supports one input file. This PR fixes this issue by going over each bc file separately.
