      idtree: Fix undefined behaviour (left shift of signed value) · 36a15d7d
      David Gibson authored
      ~0 will be signed and negative on any 2s complement system, and
      left shifting a negative value has undefined behaviour in C.

      idtree: Fix comparison is always false warning · 2b48199f
      David Gibson authored
      idtree.c:146 triggers a "comparison is always false" warning on some
      compiler configurations, since the 'id' variable is unsigned.
      
      Elsewhere in the module ids seem to be represented by (signed) ints, so
      use the same convention here, suppressing the warning and also maybe being
      more correct in other ways.

      htable: Mark functions constructed by HTABLE_DEFINE_TYPE as UNNEEDED · 71b4e3ad
      David Gibson authored
      The HTABLE_DEFINE_TYPE macro builds a type-specific hash table by
      constructing a bunch of simple wrapper functions.  The user of the hash
      table may not end up using all of these.  With gcc the fact that the
      functions are inline stops an warnings about unused functions, but that's
      not the case with clang.
      
      Suppress these warnings by marking all the constructed functions except
      for name##_add() as UNNEEDED (using the macro from ccan/compiler).  _add
      is left alone on the grounds that a hash table you never add anything to
      isn't much use, so this will help you to spot an entirely redundant
      HTABLE_DEFINE_TYPE invocation.  *_init() would be a more obvious choice,
      except that there is both *_init() and *_init_sized() and you only need
      to use one of these.

      strmap: Convert to using TCON_WRAP() instead of plain TCON() · ab244401
      David Gibson authored
      The usual way of construction strmap objects is to use the STRMAP_MEMBERS()
      macro which expands to both a raw strmap structure and a tcon type canary.
      However, the tcon type canary involves a flexible array member which means
      that in standard C99 STRMAP_MEMBERS() must appear only at the end of a
      structure definition.  But worse, that structure can then only appear at
      the end of any other structure it is included in, which is pretty
      inconvenient for the intended purpose of creating type specific strmaps.
      
      gcc extensions allow this to work (somehow), but clang complains loudly
      about it.
      
      The tcon module already includes the TCON_WRAP() mechanism, which already
      provides this same sort of type-specific definitions in a more general way.
      So convert strmap (and its users) to that approach.
      
      This removes STRMAP_MEMBERS() entirely, breaking compatibility.  I'm hoping
      strmap is used in few enough places that we can get away with that.

      deque: check HAVE_STATEMENT_EXPR, tweaks from feedback · 3022d16d
      Dan Good authored
      Thanks to the detailed feedback from David Gibson, I made the
      following improvements:
      
      * add missing includes
      * check for statement expression support, give an error if absent
      * ccanlint directive to skip "without features" steps
      * add license ref to top of source files
      * rename run1.c test to api1.c

      strgrp: Cache cosine popcounts to reduce computation · 4a439212
      Andrew Jeffery authored
      Neatly, this reduces some of the OpenMP-related noise in the
      implementation by removing the need for the include. The loop body of
      grp_for() is also clearer as a result of the change; the changes to the
      function interfaces motivated a re-think of the complexity here.
