[patch 0/9] Flattening and initial module rebuilding

[patch 0/9] Flattening and initial module rebuilding

[Andrew MacLeod]

This is a series of 9 patches which does some flattening, some module 
building, and some basic cleanups.

  I am presenting them as 9 patches for easier review. The latter couple 
of patches affect a lot of the same files that follow on patches then 
adjust, I've decided NOT to put the automated changes in with each of 
those patches.

There are 8 patches showing the key changes, and then the 9th patch is 
an aggregate of the first 8 key changes, plus the final result of the 
impact on all the source files.  This is the only patch I'd like to commit.

  The automated tools which generate the source changes have been 
significantly enhanced.  When a header is flattened, the source file is 
checked for the existence of the headers which need moving, and any 
which are already present are left if they are in the right order. Any 
duplicate are also removed.

  A similar process is used when an aggregation file like backend.h or 
ssa.h is processed. Any occurrences of the aggregated headers are 
removed from the source file so there are no duplicates.  The aggregated 
headers are typically only placed in a source file if 3 or more of the 
headers would be replaced.  (ie, if only bitmap.h is included, I don't 
just blindly put backend.h in the file.)   This number came from 
analysis of a fully flattened and include-reduced tree, and seemed to be 
the sweet spot.

  With the aggregation and flattening, the order of some includes can 
get shifted around with other files in between, so the tools also ensure 
there is a "blessed" order which will make sure than any pre-reqs are 
always available.  Right now, its primarily:

config.h
system.h
coretypes.h
backend.h
tree.h
gimple.h
rtl.h
df.h
ssa.h

And if any of the aggregators are not present, then any headers which 
make up the aggregator are in the same relative position.

The tools actually produced all these patches with no tweaking to solve 
compilation failures.. which was very helpful.  The old ones needed some 
guidance and were a bit finicky.

I can adjust any of this quite easily, or present them in a different 
way if you don't like it this way.  Again, my goal is to check in just 
the final patch which does all the work of first 8 patches.    It would 
be a lot less turmoil on the branch.   I can do it in smaller chunks if 
need be.

[patch 1/9] header additions and aggregators

[Andrew MacLeod]

[-- Attachment #1: Type: text/plain, Size: 2452 bytes --]

This patch implements most of the core concepts described in my previous 
email (https://gcc.gnu.org/ml/gcc-patches/2015-06/msg01846.html)  It 
goes into detail of the analysis which resulted in this layout.  Most of 
the unnecessary prerequisites have been removed, so we can start 
introducing back some of the required files.

  The changes in this patch:

* symtab.h is required for tree-core.h to compile, so include it.

* rtl.h does not require flagfs.h, but it does need hard-reg-set.h, and 
it turns out that any build files which need rtl.h actually have 
hard-reg-set.h available... so we can simply include it there.
   Furthermore, now that hard-reg-set.h is being included, all the 
conditional compilation code on HARD_CONST can also be removed. This 
removes a subtle ordering that you needed to make sure hard-reg-set.h 
was included before rtl.h, or certain routines didn't appear to be 
available.

* regs.h includes both hard-reg-set.h and rtl.h.  Turns out 153 of the 
155 files which include regs.h also included rtl.h already... so simple 
remove the includes.

* cfg.h requires dominance to compile, so include it.

* gimple.h requires tree-ssa-alias.h and gimple-expr.h to compile, so 
include them

* introduce backend.h which includes the files most frequently required 
by libbackend.a objects. they are tm.h, function.h, bitmap.h, sbitmap.h, 
predict.h, basic-block.h, and cfg.h

gimple-ssa.h does not need tree-hasher.h., so remove it.

* Introduce ssa.h as an aggregator for commonly needs ssa files.  I 
originally thought I could use tree-ssa-operands.h, but alas, there are 
ordering issues where many of the headers require the contents of 
tree-ssa-operands.h.  So I'd either have to put all these includes at 
the bottom of the file, or create a new file.  I think a new file is a 
better solution.

This patch actually compiles as is, but there are  a number of followup 
manipulations in the final source update. For each source file, any 
includes which occur in one of these files are removed, avoiding 
duplicates.

In the case of backend.h and ssa.h, any backend file which used 3 or 
more of the aggregated includes are replaced with the aggregator.

Further aggregations may be done for front end and other components 
after the include reduction is eventually performed.

Bootstraps from scratch on x86_64-unknown-linux-gnu with no new 
regressions. Also compiles all the files in config-list.mk.

[patch 2/9] flatten regset.h

[Andrew MacLeod]

[-- Attachment #1: Type: text/plain, Size: 622 bytes --]

This patch flattens regset.h.  it only includes bitmap.h which will come 
from backend.h and hard-reg-set.h which is going to be included by 
rtl.h.  The vast majority of files which include regset already include 
rtl.h, so its almost never needed.

This patch shows the result on all files in a virgin state (ie, as if no 
other patch has been applied) note sel-sched-ir.h and df.h both include 
regset.h.. its flattened into them as well, but will later come out when 
those 2 are flattened.

bootstraps from scratch on x86_64-unknown-linux-gnu with no new 
regressions. Also compiles all the files in config-list.mk.

[patch 4/9] Flatten sel-sched-dump.h and sel-sched-ir.h

[Andrew MacLeod]

[-- Attachment #1: Type: text/plain, Size: 364 bytes --]

This patch flattens both sel-sched-dump.h and sel-sched-ir.h. Both these 
files end up including cfgloop.h, so in preparation for flattening 
cfgloop.h, flatten these.  Note they actually have only a small effect 
on what includes them.

Bootstraps from scratch on x86_64-unknown-linux-gnu with no new 
regressions. Also compiles all the files in config-list.mk.

[patch 5/9] Flatten ira-int.h

[Andrew MacLeod]

[-- Attachment #1: Type: text/plain, Size: 372 bytes --]

  Flatten ira-int.h, yet another header that includes cfgloop.h. Most of 
the includes from here do actually make it into the source files, so 
once the include reduction is completed and we see if they are actually 
needed, some may go back in.

Bootstraps from scratch on x86_64-unknown-linux-gnu with no new 
regressions. Also compiles all the files in config-list.mk.

[patch 7/9] Flatten cfgloop.h

[Andrew MacLeod]

[-- Attachment #1: Type: text/plain, Size: 473 bytes --]

This patch flattens cfgloop.h.  cfgloopmanip.h is utilized by numerous 
files which include cfgloop.h, so it seems to make sense to leave it 
here. The other 3 header files are going to form part of backend.h, so 
take them out.

I didn't bother posting the changes to all the source files since 
aggregating with backend.h would undo every one.

Bootstraps from scratch on x86_64-unknown-linux-gnu with no new 
regressions. Also compiles all the files in config-list.mk.

[patch 8/9] Flatten df.h

[Andrew MacLeod]

[-- Attachment #1: Type: text/plain, Size: 714 bytes --]

This patch fixes up df.h. It contains 5 headers that will form part of 
backend.has well as hard-reg-set.h which is now going to be included by 
rtl.h.

The other 3 includes are required for df.h to compile, and it makes 
sense to leave them here.

furthermore, resource.h, sched-int.h and valtrack.h all include df.h, 
amongst other things, so flatten them as well. Now only source files 
will include df.h and we can see if it may belong in some other 
aggregator (or even become one) after include reduction.

All the requisite adjustments to source files will be in the final patch.

Bootstraps from scratch on x86_64-unknown-linux-gnu with no new 
regressions. Also compiles all the files in config-list.mk.

[patch 9/9] Final patch with all changes

[Andrew MacLeod]

[-- Attachment #1: Type: text/plain, Size: 431 bytes --]

This is the big daddy. THe first patch is an aggregation of the header 
file changes from the first 8 patches.

The second patch is adjustments to the gen*.c build files to remove 
duplicate includes and such.

The third patch is the net cumulative effect on all the source files.

Bootstraps from scratch on x86_64-unknown-linux-gnu with no new 
regressions. Also compiles all the files in config-list.mk.

OK for trunk?

This patch removes #include "insn-attr.h" from sel-sched-ir.h without adding
it to .c files.  I'm curious how it works, is that file now arranged to be
included elsewhere?  (sorry if I missed it, but the patch series does not seem

That is because every file which includes sel-sched-ir.h  already 
included insn-attr.h so didn't need adjustment...

The set of 9 patches is fine for the trunk.  Just a few discussion points...

One of the things I keep thinking about as these changes fly by is your 
scripts.  Is there a reasonable possibility for you to add your scripts 
to the contrib/ directory or something similar to aid us in any future 
header file refactoring?  Yes, I know that in theory we should never 
have to do this again, but I also know that reality can be rather different.

Presumably the aggregators, by policy, are to have #includes and nothing 
else, right?  If so, we might want a comment to that effect in them.

It's a bit of a shame that function.h is in backend.h, along with 
predict (which is presumably needed by basic-block/cfg?).

yes, with a bit of tweaking and enhancement they can be generally 
useful.  They are all in python.  And no one is allowed to make comments 
like "OMG thats so inefficient" or "what a horrible way to do that" 
:-)   My goal was getting things done and sometimes the brute force 
approach works great when the machine sare fast enough :_)

Yeah, will do.

Yeah,once things settle down someone could tweak things more. If I make 
the tools available, people can do their own analysis and adjusting.

function.h provides cfun which is used all over the place..9 backend 
header files use it,and a few like gimple.h actually require struct 
function to be defined.

predict.h is actually required by gimple.h for a few reasons, enum 
be_predictor is used in parameter lists and a few inlines use the TAKEN, 
NOT_TAKEN macros
Its also needed by cfghooks.h, and betwen those 2 files, its just needed 
by  a very good chunk of the backend. .. 219 of the 263 files which 
include backend.h need it.
We could move the 2 enums and TAKEN/NOT_TAKEN to coretypes or something 
like that and it would probably cut the requirements for it by a *lot*.

Works for me...  I'm sure Martin S. is cringing at my python scripts 
right now, so I completely understand.

Right.  I suspect that we may want to look at cleaning that up a bit in 
the future.  There's bits in there that are relatively backend specific, 
some bits that look like front-end things, and cfun which is a context 
container.  Untangling that mess is likely to be painful.

Might be something for a follow-up (moving the enums).

blah, not so trivial.  One of the primary things predict.h does is 
create enum br_predictor by including predict,def.. so moving that enum 
doesnt really make sense.

Fixing gimple,h isn't too bad, I could split the prediction stuff out 
into gimple-predict.h and include it in the 4 places its needed (as you 
might be able to tell, Ive tried this :-)

However, it doesn't do much good.  cfghooks.h is included by 
basic-block.h.. which is needed virtually everywhere :-P

There are just 2 entries in the hooks table which require  'enum 
br_predictor', but I dont think it makes sense to move things out of the 
cfghook structure.. I suppose once could create a prediction_hooks 
structure.. and put it in predict_hooks.h...  but I think thats probably 
going to far to avoid including a file which makes some logical sense..

The other option is to pull cfghooks.h out of basic-block.h and include 
it seperately on its own.. What is the reason its in there now? It 
appears to not have a cyclic dependency which is the usual reason to 
have an include in the middle of a file.  Or perhaps the reason no 
longer exists?  There is a comment at the top of cfghooks.h :
    /* Only basic-block.h includes this.  */
but no rationale.

I moved it to the very bottom of the file and everything still seems to  
compile fine   I can try flattening it out of basic-block.h and only 
including it in places that need it... that should eliminate the need to 
put predict.h in a lot of places I would think.

I don't guess we're approaching a world where the front-ends don't need 
basic-block (and thus cfghooks, predictions, etc etc).

I don't recall.  It may have seemed to make sense at the time :-)  You'd 
have to do the archaeology and even if you did, you might not get an answer.

If it's not too much trouble, seems like it might be worth trying.  It 
just feels like the prediction bits shouldn't be that pervasive.

ok,  so the results are in. a bit painful to unravel :-)  these are the 
steps
- Splitting the prediction bits of gimple.h out to gimple-predict.h and 
putting that file where it matters (5 files as it turns out)
- Next split cfghooks.h out from basic-block.h and put it in the files 
that it is needed in.
- then I moved  predict.h out of backend.h  I added it as an include to 
cfghooks.h and gimple-predict.h and adjusted source files accordingly..
- Finally, try to remove the extraneous cfghooks.h and predict.h files.

caveat, I did no reductions on config/* files nor on languages beyond 
stage1 builds... havent gotten to enhancing to tool to deal with that 
yet.. its coming as a part of the general include reduction.. so I'll 
havdle these bits then.  .
Then result using numbers which exclude those caveat files:
predict.h ends up in 68 files out of the original 179 it was in by 
itself. . ( ie excluding files with cfghooks.h or gimple-predict.h)
cfghooks.h ends up in 89 of the original 268 that basic-block was 
present in.

The total result affect 227 files.

Now, predict.h is *still* more pervasive than it needs to be, but thats 
a different patch :-).  There are  a set of routines in there like  
optimize_{fucntion,loop,edge,bb}_for{speed,size}_p()  that are the 
reason half the files need it.   those should probably be moved 
somewhere else since they aren't really prediction related :-P Maybe a 
better spot will show up when the rest of the include reductions are done.

I've attached a patch.  It bootstraps on x86_64-unknown-linux-gnu, and 
I'm running regressions.  To be safe, I'll run config-list.mk overnight 
to be sure.
assuming its all fine, OK for trunk then?

OK assuming everything is fine with your overnight run.

BTW, you're showing your age -- a .Z file...  Thankfully gzip will 
handle that just fine.  (And yes, I realize the irony here that gzip is 
probably considered ancient as well given bzip2 and xz).

Ha. I just type compress and move on. :-)  but yeah, lookitthat. bzip2 
is about 40% the size :-)    ok, maybe next time :-)   If i remember...
