[Bug ld/16017] New: LD creates invalid PLT instructions on CORTEX-M3
https://sourceware.org/bugzilla/show_bug.cgi?id=16017
Bug ID: 16017
Summary: LD creates invalid PLT instructions on CORTEX-M3
Product: binutils
Version: 2.23
Status: NEW
Severity: normal
Priority: P2
Component: ld
Assignee: unassigned at sourceware dot org
Reporter: lotharlutz at gmx dot de
When compiling a shared library for cortex-M3, ld creates ARM instructions for
jumping to the plt and the plt itself. But the cortex only supports thumb
instructions, which results in a runtime error.
Test case:
compile test.c with
arm-none-eabi-gcc -fPIC -nostartfiles -nostdlib -mcpu=cortex-m3 -mthumb -shared
-o libtest.so test.c
test.c:
int foo();
int bar()
{
return foo();
}
Result:
Disassembly of section .plt:
0238 <.plt>:
238: e52de004push{lr}; (str lr, [sp, #-4]!)
23c: e59fe004ldr lr, [pc, #4]; 248
240: e08fe00eadd lr, pc, lr
244: e5bef008ldr pc, [lr, #8]!
248: 8098muleq r0, r8, r0
24c: e28fc600add ip, pc, #0, 12
250: e28cca08add ip, ip, #8, 20 ; 0x8000
254: e5bcf098ldr pc, [ip, #152]! ; 0x98
Disassembly of section .text:
0258 :
258: b580push{r7, lr}
25a: af00add r7, sp, #0
25c: f7ff eff6 blx 24c
260: 4603mov r3, r0
262: 4618mov r0, r3
264: bd80pop {r7, pc}
266: bf00nop
24c, 250, 254 as well as 25c are ARM instructions and therefore invalid on
cortex-m3 cores.

https://sourceware.org/bugzilla/show_bug.cgi?id=15993 --- Comment #5 from Sergio Durigan Junior --- I will ask you to create another bug for those. gdb-7.6.1/bfd/elf32-rl78.c:1112 and gdb-7.6.1/bfd/elf32-rx.c:3180 are BFD bugs and should be opened against binutils. gdb-7.6.1/sim/erc32/float.c:95 is a GDB bug and can be opened against it. You can put me on the Cc list and I will take ownership.
