("[MC][ELF] Emit a relocation if target is defined in the same section and is
non-local"), the following assembly for arm no longer compiles:
# clang -target armv6-gnueabihf -c adr-reloc.s
adr r0, foo
.global foo
foo:
Before:
$ clang-llvmorg-10-init-17163-g241f330d6ba -target armv6-gnueabihf-freebsd13.0
-c adr-reloc.s
$ llvm-objdump -d adr-reloc.o
adr-reloc.o: file format ELF32-arm-little
Disassembly of section .text:
00000000 $a.0:
0: 04 00 4f e2 sub r0, pc, #4
After:
$ clang-llvmorg-10-init-17164-g2bfee35cb86 -target armv6-gnueabihf -c
adr-reloc.s
adr-reloc.s:2:1: error: unsupported relocation on symbol
adr r0, foo
