when I use the option '--parallel' for mmc, but did not explicitely
specify a parallel grade, the compilation fails with:
mercury_compile: error: the Mercury standard library cannot be found in grade asm_fast.par.gc.
This is unsuprising, as this grade is not installed (does is even
I fixed this locally by adding
% The pthreads headers on some architectures (Solaris, Linux)
% don't work with -ansi.
option_implies(parallel, ansi_c, bool(no), !Globals),
-> option_implies(parallel, stack_segments, bool(yes), !Globals), <-
in handle_options.m for the convert_options_to_globals predicate. This
change seems to work with 14.01.1.
Yet, I am fully aware that this is the *wrong solution*. It adds 'stseg'
to any parallel grade, even for hlc.par, where is does not make any
I still think that selecting a valid parallel grade for asm_fast would
be a better idea than failing on compilation when specifying the
'parallel' option without explicit parallel grade. IIRC, I never had a
low-level parallel grade without '.stseg', therefore I propose adding
the 'stack_segments' option to parallel, low-level C target.
