Re: Some thoughts and quetsions about the data flow infrastracture

Combiner is an older approach of code selection. Combine can be considered both as code selection or optimization. Likewise, CSE. In many cases, especially now that we have the tree optimizers, CSE does more code selection (best choice of operand) than CSE. So you could say that CSE and

Performance regression on the 4.3 branch?

I noticed a performance regression on the following code: $ cat a.c #include stdint.h #include stdio.h void add256 (uint64_t x[4], const uint64_t y[4]) { unsigned char carry; x[0] += y[0]; carry = (x[0] y[0]); x[1] += y[1]+carry; carry = carry ? (x[1] = y[1]) : (x[1] y[1]); x[2] +=

Re: Some thoughts and quetsions about the data flow infrastracture

Well before GCC 4.x there was an attempt that a few of us worked on to try to move the algebraic simplifications from combine to simplify-rtx.c, just like we put tree folding in fold-const.c. At that point, combine just becomes bookkeeping. The problem with that approach was what to do with

Re: Some thoughts and quetsions about the data flow infrastracture

Actually, simplify-rtx.c now uses nonzero_bits and num_sign_bit_copies: these ask combine for the value in the case of pseudos, via the RTL hooks mechanism. Right. That was certainly a step (and was discussed a while ago), but doing it more globally would make it even easier. 1) what to

minimal version of bison for Gcc?

Hello, It seems according to http://gcc.gnu.org/install/prerequisites.html that the minimal version of bison required in GCC (for those hacking the few .y files) is 1.28 (released in july 1999). Is there a reason why a 2.x version of bison would not be acceptable? FWIW, I am not considering

Yes, one possibility is to use a RTX hook for this too. By default you would return NULL (and this would propagate up); in combine you could override it to return the CLOBBER. I really don't see why. Look at when combine calls the simplify routines now. If they return zero, it uses the

mudflap vs bounds-checking

Hi all, I was somewhat used to the bounds-checking patches for GCC 3.x from Herman ten Brugge. Now that GCC-4.x ships with mudflap, I am a bit confused, since the bounds-checking patches also exist at least for until GCC-4.0.2. What is the difference between the two systems? Thanks,

Re: Some thoughts and quetsions about the data flow infrastracture

Some of the combine simplifications (you obviously know that) work by hoping that the CLOBBER is simplified away. I don't think you can preserve all their power if you propagate NULL. In most cases you can replace CLOBBER with NULL, but I don't think that's possible everywhere. Yeah, but
