Bug ID: 99410
Summary: Nios II Error: branch offset out of range
Product: gcc
Version: 7.3.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: giulio.benetti at benettiengineering dot com
Target Milestone: ---
When building git package on Buildroot gcc throws:
'''
[ 98%] Building C object
src/CMakeFiles/bellesip.dir/antlr3c/src/antlr3treeparser.c.o
/tmp/ccDtjRfo.s: Assembler messages:
/tmp/ccDtjRfo.s:210798: Error: branch offset out of range
/tmp/ccDtjRfo.s: Fatal error: branch relaxation failed
'''
To reproduce it:
# git clone git://git.busybox.net/buildroot
# wget https://git.busybox.net/buildroot-test/tree/utils/br-reproduce-build
- modify BASE_GIT=... with your buildroot path in br-reproduce-build then:
# chmod a+x br-reproduce-build
# ./br-reproduce-build 71f26fd81db8e9b19b3f18f3f3cefd9c768f094f
The only way I've found to build correctly is to turn off optimization
overriding CFLAGS with -O0.
