            Bug ID: 17330
           Summary: Fails to build on sh4: pcrel too far
           Product: binutils
           Version: 2.25 (HEAD)
            Status: NEW
          Severity: normal
          Priority: P2
         Component: binutils
          Assignee: unassigned at sourceware dot org
          Reporter: glaubitz at physik dot fu-berlin.de

Hello!

binutils currently fails to build from source when compiling on SH4 (Hitachi
SuperH).

gcc-4.9 seems to generate invalid assembly code which trips the assembler:

/bin/sh ./libtool --tag=CC   --mode=compile gcc -DHAVE_CONFIG_H -I.
-I../../opcodes  -I. -I../../opcodes -I../bfd -I../../opcodes/../include
-I../../opcodes/../bfd    -W -Wall -Wstrict-prototypes -Wmissing-prototypes
-Wshadow -g -O2 -MT hppa-dis.lo -MD -MP -MF .deps/hppa-dis.Tpo -c -o
hppa-dis.lo ../../opcodes/hppa-dis.c
libtool: compile:  gcc -DHAVE_CONFIG_H -I. -I../../opcodes -I. -I../../opcodes
-I../bfd -I../../opcodes/../include -I../../opcodes/../bfd -W -Wall
-Wstrict-prototypes -Wmissing-prototypes -Wshadow -g -O2 -MT hppa-dis.lo -MD
-MP -MF .deps/hppa-dis.Tpo -c ../../opcodes/hppa-dis.c  -fPIC -DPIC -o
.libs/hppa-dis.o
/tmp/ccZrwibi.s: Assembler messages:
/tmp/ccZrwibi.s:1903: Error: pcrel too far

The full build log can be found on Debian's buildd website [1]. I have also
filed a bug report to Debian [2] where I reference I similar bug which was
previously found in gcc [3]. In the end, it might be a gcc bug but I am not
sure as I have observed this bug only for this particular version of binutils.

Cheers,
Adrian
