One of conditions in skip_prologue() was never visited if there was mflr instruction that moves the link register to a register different than r0. This condition expects non shifted value of `lr_reg`. Previously offset of link register was never saved for registers different than r0. gdb/ChangeLog: 2018-01-31 Nikola Prica <nikola.prica@rt-rk.com> * rs6000-tdep.c (skip_prologue): Remove shifting for lr_reg and assign shifted lr_reg to fdata->lr_register when lr_reg is set. gdb/testsuite/ChangeLog: 2018-01-31 Nikola Prica <nikola.prica@rt-rk.com> * gdb.arch/powerpc-prologue-frame.s: New file. * gdb.arch/powerpc-prologue-frame.c: Likewise. * gdb.arch/powerpc-prologue-frame.exp: Likewise.
