Bug ID: 83211
Summary: Warning: ignoring incorrect section type for
.init_array.00200
Product: gcc
Version: 6.4.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: rdiezmail-gcc at yahoo dot de
Target Milestone: ---
I recently upgraded my embedded ARM Cortex-M4 toolchain from GCC 6.3 to GCC
6.4, and Binutils from 2.28 to 2.29.1 (among other minor component upgrades).
My C++ code is using the following for a static routine:
__attribute__ ((constructor (200)))
After the upgrade I am getting this warning now:
/tmp/cc79zoMV.s: Assembler messages:
/tmp/cc79zoMV.s:5079: Warning: ignoring incorrect section type for
.init_array.00200
/tmp/cc79zoMV.s:5112: Warning: ignoring incorrect section type for
.fini_array.00200
Normally, GCC emits this kind of section statements during compilation:
.section .init_array,"aw",%init_array
But for the "__attribute__ ((constructor (200)))" code, it emits this instead:
.section .init_array.00200,"aw",%progbits
Binutils saw this change recently:
https://sourceware.org/bugzilla/show_bug.cgi?id=21287
So I am guessing that is what is causing the new warning.
I suppose that GCC needs an update to match that Binutils change.
