FIXME in gcc/gimplify.c

FIXME in gcc/gimplify.c

[nick]

Greetings all,

Not sure why this exists still as tree-eh.h is including in tree-eh.c which defines this header
as used for this FIXME:
 #include "tree-pass.h"          /* FIXME: only for PROP_gimple_any */

Unless there is something in the build ordering that would cause issues it's indirectly including
that way so this header inclusion should now be removed. Unless I'm missing something else
which is fine.

If not just let me known and I will just send a patch for it,
Nick

Hi.

Martin,

Seems this was refactored in commit id,7c29e30e. Andrew MacLeaod seems to be the author so I'm asking him
for why this fixme was added during his major reordering and refactoring of included headers in various .c
or .cc files in gcc.

Presumably because I didn't add it?  I just refactored the major 
spaghetti-interdependencies, not all the include files.
If you look back into 2012 before I did any refactoring, that file 
looked like:

#include "config.h"
#include "system.h"
#include "coretypes.h"
#include "tm.h"
#include "tree.h"
#include "gimple.h"
#include "tree-iterator.h"
#include "tree-inline.h"
#include "tree-pretty-print.h"
#include "langhooks.h"
#include "tree-flow.h"
#include "cgraph.h"
#include "timevar.h"
#include "hashtab.h"
#include "flags.h"
#include "function.h"
#include "ggc.h"
#include "diagnostic-core.h"
#include "target.h"
#include "pointer-set.h"
#include "splay-tree.h"
#include "vec.h"
#include "gimple.h"

#include "langhooks-def.h"      /* FIXME: for lhd_set_decl_assembler_name */
#include "tree-pass.h"          /* FIXME: only for PROP_gimple_any */


so that comment predates anything I did to it.   I specifically left any 
comments that existed as I refactored the core bits.

Andrew,

I assumed so but it was the last commit and have your names. I will leave this thread open for discussion if anyone knows what
the outstanding issues with header refactoring as required for fixing those comments. If someone comments and is able to give
me a heads up about what needs refactoring I will be glad to do it in a patch or probably patch series.

Once upon a  time someone went thru the compiler and added comments to a 
few of thesecomments to  #include's when there were only one or two 
dependencies.

I'm not sure what the original intention was, or why it was tagged as 
"FIXME".    The problem with this approach is it can rapidly get out of 
date.. as can be seen by the other undefined messages that caused the 
compilation issue when the #Include is removed.  There is actually half 
a dozen things required from this include file.

We almost removed all those comments when the re-factoring was being 
performed, but it was automated and there were other comments that were 
relevant, so we elected to just preserve all comments.

I don't see any particular reason or need to fix these includes. I think 
the comments are out of date and unnecessary, but won't lose any sleep 
over them.

tree-pass.h is required to compile this file. It is not included by any 
other include file, so there is no ordering issue I can see, nor any 
need to remove the #include.
