Fix SourceForge bug report #129892, "profiler map__lookup failed
Estimated hours taken: 3 Fix SourceForge bug report #129892, "profiler map__lookup failed in grade hlc.gc.memprof". The remaining problem that was still causing failures for this test case was that demangling isn't implemented for the MLDS back-end. When symbols that the MLDS back end generates are fed through the demangler, it demangles some distinct symbols to the same name. This causes the profiler to abort, because it assumes that each distinct symbol demangles to a different name. The fix is to turn off demangling when profiling programs built in MLDS grades. NEWS: Mention that we haven't implemented symbol demangling in the profiler for the MLDS back-end yet. doc/user_guide.texi: Document that for profiling of programs built with `--high-level-code' you need to use the `--no-demangle' option. tools/test_mercury: When testing the profiler in hl* grades, pass `--no-demangle' to mprof, and compare with *.mprof-exp2 rather than *.mprof-exp. tests/benchmarks/poly.mprof-exp2: New file. Contains alternative expected output for this test case, to match what is output for grade hlc.gc.memprof (at -O2). profiler/options.m: The `--(no-)demangle' option is not a filename option, so document it under the "Profiler options" section, rather than the "Filename options" section. Also fix a typo (s/Ouput/Output/) and a thinko (s/unmangled/mangled/) in the description of that option.
