[PATCH] Flatten tree.h and tree-core.h (Version 3)

[PATCH] Flatten tree.h and tree-core.h (Version 3)

[Michael Collison]

[-- Attachment #1: Type: text/plain, Size: 42924 bytes --]

This patch flattens tree.h and tree-core.h. This is a revised patch that 
does not include tree-core.h as a result of flattening.

Version 3 of the patch adds the header files removed from tree-core.h to 
gcc-plugin.h in order to allow ggc-common.c to compile. This is a recent 
issue seen on trunk.

I removed the includes in tree.h and tree-core.h except for the include 
of tree-core.h in tree.h.

I modified genattrtab.c, genautomata.c, genemit.c, gengtype.c, 
gengtype.c, genoptinit.c, genoutput.c,
genpeep.c, genpreds.c, and optc-save-gen-awk to include the the 
necessary include files removed from
tree.h and tree-core.h when generating their respective files.

I removed three inline functions from tree.h and relocated them to 
fold-const.c and exported them in fold-const.h. The functions are:

convert_to_ptrofftype-loc
fold_build_pointer_plus_loc
fold_build_pointer_plus_hwi_loc

All other changes include the necessary include files removed from 
tree.h and tree-core.h. Note the patches modifies all the front-ends.

I bootstrapped on x86 with all languages. I also bootstrapped on all 
targets listed in contrib/config-list.mk with c and c++ enabled.

Is this okay for trunk?

Please note that the GCC tree has many different ChangeLog files, so
it is incorrect to put everything into gcc/ChangeLog.  E.g. fortran/
entries belong into gcc/fortran/ChangeLog and should not have
fortran/ prefixes, etc.  I've fixed it up for this time, but please
take care about it next time.

Oops, sorry about that, I will take care henceforth.
Thanks for fixing it up.

Which languages was this tested with?

This broke the build of the jit, with dozens of errors e.g.:

In file included from ../../src/gcc/tree.h:23:0,
                 from ../../src/gcc/jit/jit-common.h:26,
                 from ../../src/gcc/jit/jit-logging.h:24,
                 from ../../src/gcc/jit/jit-logging.c:25:
../../src/gcc/tree-core.h:171:9: error: ‘MAX_MODE_COMPLEX_FLOAT’ was not
declared in this scope
       + MAX_MODE_COMPLEX_FLOAT
         ^

I've fixed it with the attached; tested with "make check-jit", with
jit.sum having:
  # of expected passes  7152

Committed to trunk as r219411.

Great work! Almost no fallout.

Though I see some fallout for tilepro-linux, see eg. these builds:
tilegx:  http://toolchain.lug-owl.de/buildbot/show_build_details.php?id=396528
tilepro: http://toolchain.lug-owl.de/buildbot/show_build_details.php?id=397033

#include "symtab.h" is there, so probably too late? Fails for both, tilepro and tilegx.

Re: [BUILDROBOT] tilepro-linux/tilegx-linux fallout from flattening

[Michael Collison]

The issue is that tilegx includes expr.h which includes tree-core.h. A 
simple solution is to include "symtab.h" before "expr.h" in tilegx.c. 
The port has a unrelated link error after this change.

The second possiblity is to resolve this using Prathmesh latest patch 
(submitted today) for flattening expr.h which removes the dependency on 
tree-core.h. Thoughts?

Yes, I am seeing this link error after building expr.h too -;(

I retained tree-core.h in expr.h, so I guess flattening won't remove

No objc++ is non-default:

$ grep build_by_default */config-lang.in
go/config-lang.in:build_by_default="no"
java/config-lang.in:#build_by_default=no
jit/config-lang.in:build_by_default="no"
lto/config-lang.in:build_by_default=no
objcp/config-lang.in:build_by_default=“no"

I saw changes to objcp, so, I had assumed you did it, otherwise I was going to mention it.

Michael had built objcp for tree.h flattening patch and tested it.

Thanks,
