Bug ID: 28292
Summary: v850-elf-ld: Opcode "st.b" is cracked in relocation
process
Product: binutils
Version: 2.37
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: binutils
Assignee: unassigned at sourceware dot org
Reporter: t-hosh...@pony-e.jp
Target Milestone: ---
Created attachment 13637

crtE.asm and test.ld
Attached crtE.asm has 2 instruction their uses st.b.
These instructions would be finally identical I guess through relocation by
linker.
However, relocated binary shows two different instruction.
(second st.b have been replaced by sum of 0x5740 and 0xF06E?)
-- Assembly (from crtE.asm)
st.b r10, -0x0F92[r0] -- use immediate
st.b r10, VSWC[r0] -- VSWC externally defined by linker script
-- Linker script (test.ld)
SECTIONS { .text 0x00000000 : { *(.text*) } }
VSWC = -0x0F92; /* FFFFF06EH */
-- Assemble and link commands
v850-elf-as crtE.asm -o crtE.o \
&& v850-elf-ld --script=test.ld -o a.out crtE.o
-- v850-elf-objdump -d a.out
00000000 <__start>:
