Estimated hours taken: 6 Add a `--debug' option for Mercury-level debugging using the trace-based debugger. scripts/init_grade_options.sh-subr: scripts/parse_grade_options.sh-subr: scripts/mgnuc.in: scripts/ml.in: compiler/options.m: compiler/handle_options.m: compiler/mercury_compile.m: Split the old `--debug' option into `--low-level-debug' (formerly the absence of -DSPEED, now handle by -DLOWLEVEL_DEBUG) and `--c-debug' (passes -g to C compiler). Delete the old `debug' grade. Add support for new options `--require-tracing' (makes --trace minimum equivalent to --trace interfaces, and passes -DMR_REQUIRE_TRACING to C compiler) `--stack-trace' (passes -DMR_STACK_TRACE to C compiler; actually this one was already supported) and `--debug' (implies previous two), with corresponding grade modifiers `.trace', `.strce', and `.debug'. Actually I think there's little point in specifying just one of `--require-tracing' and `--stack-trace' so for the moment I'm just providing `--debug': the code for the more fine-grained options and grade modifiers has been added but commented out. runtime/mercury_conf_param.h: Document the new configuration parameter MR_REQUIRE_TRACING and the existing but undocumented parameter MR_STACK_TRACE. runtime/mercury_grade.h: Include MR_REQUIRE_TRACING in the mangled grade identifier. compiler/globals.m: compiler/handle_options.m: compiler/options.m: Allow new tracing type `--trace default', and make it the default. This gets replaced with `full' if require_tracing is yes or `minimal' if require_tracing is no. Also `--trace minimum' gets replaced with `interface' if require_tracing is yes. doc/user_guide.texi: Document the new `--debug', `--low-level-debug', and `--c-debug' options. scripts/mgnuc.in: compiler/mercury_compile.m: doc/user_guide.texi: Change things so that `--c-debug' does not imply `--no-c-optimize'. configure.in: Add `-fomit-frame-pointer' to CFLAGS_FOR_GOTOS on alpha-*. Empirically, this seems to be needed, otherwise lots of the test cases fail when compiled with `--no-c-optimize'. (It might also be needed for other architectures, I don't know.)
