|
||||
* sim-trace.c (toplevel): Include bfd.h.
|
||||
(trace_options): Note that --trace-linenum also turns on
|
||||
--trace-insn.
|
||||
--trace-insn. Add --trace-{branch,semantics}.
|
||||
(trace_option_handler): If --trace-linenum, also turn on
|
||||
--trace-insn.
|
||||
--trace-insn. Add --trace-branch support. If --trace-semantics,
|
||||
turn on ALU, FPU, branch, and memory tracing.
|
||||
(trace_one_insn): New function to trace an instruction. Support
|
||||
--trace-linenum.
|
||||
(OPTION_TRACE_*): Use an enum, rather than lots of defines.
|
||||
|
||||
* sim-trace.h (TRACE_LINENUM_P): Define macro.
|
||||
* sim-trace.h (TRACE_{SEMANTICS,BRANCH}_IDX): Add new macros.
|
||||
(MAX_TRACE_VALUES): Use 32, not 12 by default.
|
||||
(TRACE_branch): Add new mask.
|
||||
(TRACE_*_P): Define all possible trace_p macros.
|
||||
(trace_one_insn): Declare function.
