[LLVMdev] -ffixed option in llvm-gcc
Hi I am trying to register shadow a global variable using -ffixed option in llvm-gcc. I am able to accomplish this using gcc however llvm-gcc seems to ignore this option and generate code using the register. command line: >gcc -Wall -m64 -O3 -pthread -ftls-model=initial-exec -ffixed-r12 test.c -o test >objdump -d ./test | grep r12 >llvm-gcc -Wall -m64 -O3 -pthread
