Summary: ARM/THUMB thunk calls broken
Product: gcc
Version: 3.3.1
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: c++
AssignedTo: unassigned at gcc dot gnu dot org
ReportedBy: thomas at koeller dot dyndns dot org
CC: gcc-bugs at gcc dot gnu dot org,thomas dot koeller at
baslerweb dot com
GCC build triplet: i686-pc-linux-gnu
GCC host triplet: i686-pc-linux-gnu
GCC target triplet: arm-ecos-elf
When compiling ARM programs in THUMB mode, thunks use a 'b' instruction to branch to
the target function. Since the 'b' instruction has a very limited adressing range (+/- 256
bytes), and the thunk and its target function are placed in different sections, linking errors
are very common:
csr_camerastatus.o: In function `non-virtual thunk [nv:-24] to
CSR_CAMERASTATUS::SetProtocolError(ProtocolErrorHandler::EPROT_ERR_VAL)':
csr_camerastatus.o(.gnu.linkonce.t._ZThn24_N16CSR_CAMERASTATUS16SetProtocolErrorEN20ProtocolErrorHandler13EPROT_ERR_VALE+0x2):
relocation truncated to fit: R_ARM_THM_PC11
CSR_CAMERASTATUS::SetProtocolError(ProtocolErrorHandler::EPROT_ERR_VAL)

Log message:

PR target/12476
* config/arm/arm.c (arm_output_mi_thunk): In Thumb mode, use
'bx' instead of 'b' to avoid branch range restrictions. Output
the thunk immediately before the thunked-to function.
* config/arm/arm.h (ARM_DECLARE_FUNCTION_NAME): Do not emit
.thumb_func if a thunk is being generated. Emit .code 16 along
with .thumb_func if a thunk is not being generated.

This should be fixed in 3.4. The code already exists on the csl-arm branch and
just needs pulling up. I believe Mark has already approved doing so.

Not a regression so moving to 3.4.1 (if you fix it before make sure you move the target
back).

Target milestones are only for regressions and ABI bugs, this is neither. I said if the fix
gets applied then just change the target milestone back to where it was fixed. This is
standard practice for all of GCC. I am just move the milestone to 3.5 for now (as I assume
the csl-arm branch will be merged into the mainline), you can move it back when the fix
is applied to the mainline.
