Bug ID: 85235
Summary: [mips] Error: branch out of range
Product: gcc
Version: 6.4.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: rtl-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: mattst88 at gmail dot com
Target Milestone: ---

preprocessed (gzip'd) source file
On mips when attempting to compile cython's (cython.org) Code.c file, gcc
produces code that gas is unable to assemble, with
{standard input}:417146: Error: branch out of range
{standard input}:417161: Error: branch out of range
...
MIPS' gas supports --relax-branch which seems like it's supposed to be able to
sort this out, but it doesn't seem to.
Fails on gcc 6.4.0 and 7.3.0. Other versions untested. Totally guessing on the
Component field.
The attached Code.i demonstrates the problem with
mips64el-unknown-linux-gnu-gcc -mabi=n32 -O2 -march=loongson3a -mplt -pipe
-fno-strict-aliasing -fPIC -x c -c Code.i -o Code.o
