* infrun.c (handle_inferior_event): Move the check for return trampolines ahead of the check for function trampolines. * mips-tdep.h (MIPS_S2_REGNUM, MIPS_GP_REGNUM): New macros. * mips-tdep.c (mips_str_mips16_call_stub): New variable. (mips_str_mips16_ret_stub): Likewise. (mips_str_call_fp_stub): Likewise. (mips_str_call_stub): Likewise. (mips_str_fn_stub): Likewise. (mips_str_pic): Likewise. (mips_in_frame_stub): New function. (mips_unwind_pc): Return the return address rather than the PC if the PC of an intermediate frame is inside a call thunk. (mips_is_stub_suffix): New function. (mips_is_stub_mode): Likewise. (mips_get_mips16_fn_stub_pc): Likewise. (mips_skip_mips16_trampoline_code): Update to handle all the currently generated stub types. Don't recurse into __fn_stub thunks. Remove heuristics to handle stubs beyond etext/_etext. Use cooked register accesses. (mips_in_return_stub): Reintroduce function. (mips_skip_trampoline_code): Traverse trampolines recursively. (mips_gdbarch_init): Handle MIPS16 return trampolines. gdb/testsuite/ * gdb.arch/mips16-thunks-inmain.c: New file. * gdb.arch/mips16-thunks-main.c: New file. * gdb.arch/mips16-thunks-sin.c: New file. * gdb.arch/mips16-thunks-sinfrob.c: New file. * gdb.arch/mips16-thunks-sinfrob16.c: New file. * gdb.arch/mips16-thunks-sinmain.c: New file. * gdb.arch/mips16-thunks-sinmips16.c: New file. * gdb.arch/mips16-thunks.exp: New file.
