Summary0000280: Parser stack overflow with MSVC
DescriptionAttempting to compile compiler/options.c (from the rote-2012-04-10 srcdist) with MSVC
results in:

    fatal error C1026: parser stack overflow, program too complex

It looks as though the C code we generate for the predicate long_option/2 is too
heavily nested; I'll try to separate it out a bit and see if that avoids the limitation.
TagsNo tags attached.

Actually, the problem may be that the source distribution is built with --no-smart-indexing.
(The other approaches for string switches shouldn't bump into these sort of limitations.)

It's fine if you rebuild the .c files with --smart-indexing. In the long term, I would like to be able
to compile the MSVC version of Mercury directly from the source distribution. Some options here are:

(1) Work out whether --smart-indexing is still causing problems with the source distribution.

(2) Manually, break long_options/2 into smaller chunks.

(3) If compiling with --no-smart-indexing then change the MLDS code generator so that
it breaks deeply nested if-then-else chains into separate C functions -- i.e. get the code generator
to do (2).

The source distribution C files are now built with --smart-indexing enabled (option 1 above).
