[Bug gas/29349] New: ADR instructions generate wrong offsets in Thumb code for armv7-m

[Mr.Bossman075 at gmail dot com]

https://sourceware.org/bugzilla/show_bug.cgi?id=29349

Bug ID: 29349
   Summary: ADR instructions generate wrong offsets in Thumb code
for armv7-m
   Product: binutils
   Version: 2.37
Status: UNCONFIRMED
  Severity: normal
  Priority: P2
 Component: gas
  Assignee: unassigned at sourceware dot org
  Reporter: Mr.Bossman075 at gmail dot com
  Target Milestone: ---

In U-Boot after this commit, armv7-m fails to boot because of this commit.
https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=d3e52e120b68bf19552743fbc078e0a759f48cb7

The bug is demonstrated below in a cleaner format:
```
.syntax unified
.global bug;
.align 4
bugs:
 adr r3, bugs
.size bugs, .-bugs
.type bugs 2; // This changes offset from 4 to 3 in
include/linux/linkage.h:ENDPROC
//arm-linux-gnueabi-as  -march=armv7-m -c -o bug.o bug.S &&
arm-linux-gnueabi-objdump --disassemble=bug bug.o
```
what is more confusing is
https://sourceware.org/binutils/docs/as/ARM-Opcodes.html conflicts with the arm
docs about the ADR instruction giving a multiple of 4 on thumb.
