            Bug ID: 103370
           Summary: [12 Regression] Assembler error building glibc for
                    ColdFire soft-float
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Keywords: assemble-failure
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: jsm28 at gcc dot gnu.org
                CC: rguenth at gcc dot gnu.org
  Target Milestone: ---
            Target: m68k*-*-*

Created attachment 51849
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=3D51849&action=3Dedit
preprocessed source

Compile and assemble the attached preprocessed source (from glibc) with -O2
-fPIC -c, using a compiler configured for m68k-linux-gnu --with-arch=3Dcf
--with-cpu=3D54455 --disable-multilib (this is m68k-linux-gnu-coldfire-soft=
 in
build-many-glibcs.py).  This produces an assembler error:

/tmp/cctaeK7A.s: Assembler messages:
/tmp/cctaeK7A.s: Fatal error: Tried to convert PC relative branch to absolu=
te
jump

    tree-optimization/102880 - improve CD-DCE

though I'm guessing it was most likely to have been latent before then.=
