[LLVMdev] llvm-mc fixups

[Greg Fitzgerald]

When I use llvm-mc’s ‘-show-encoding’, it only goes as far as printing
“fixups”:



$ echo -e "adr r0, lbl\nnop\nlbl:" | llvm-mc -triple=thumbv7 -show-encoding



Outputs:

@ encoding: [A,0xa0]

@    fixup A – offset: 0, value: lbl, kind: fixup_thumb_adr_pcrel_10





To find out that it is encoded as 0xa001, I can do:



$ echo -e "adr r0, lbl\nnop\nlbl:" | llvm-mc -triple=thumbv7
-show-encoding -filetype=obj
> tmp.o

$ llvm-objdump -d tmp.o



Is there a way to get that encoding directly from llvm-mc?



Thanks,

Greg
