"sig" arguments, add "regcache" argument. * gdbarch.c, gdbarch.h: Regenerate. * infrun.c (resume): Update SOFTWARE_SINGLE_STEP call arguments. (handle_inferior_event): Call remove_single_step_breakpoints directly instead of calling SOFTWARE_SINGLE_STEP to remove breakpoints. * alpha-tdep.c (alpha_software_single_step): Update argument list. Remove handling of !insert_breakpoints_p case. * arm-tdep.c (arm_software_single_step): Likewise. * cris-tdep.c (cris_software_single_step): Likewise. * mips-tdep.c (mips_software_single_step): Likewise. * rs6000-tdep.c (rs6000_software_single_step): Likewise. * sparc-tdep.c (sparc_software_single_step): Likewise. * spu-tdep.c (spu_software_single_step): Likewise. * alpha-tdep.h (alpha_software_single_step): Update prototype. * mips-tdep.h (mips_software_single_step): Likewise. * rs6000-tdep.h (rs6000_software_single_step): Likewise. * sparc-tdep.h (sparc_software_single_step): Likewise.
