[Bug fortran/43996] ICE in simplification of spread intrinsic
--- Comment #9 from dominiq at lps dot ens dot fr 2010-05-06 08:51 --- (In reply to comment #8) For increasing N it (a) takes longer and longer - probably quadratic time - N=100: 0.716u 0.031s 0:00.75 N=200: 5.297u 0.071s 0:05.37 N=400: 40.334u 0.125s 0:40.76 It looks like cubic time in N. For M=1, I would expect that MATMUL is quadratic in N (although I did not check). Does this mean that building each element is O(N)? and (b) eventually all memory will be used which leads to a crash. As in http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40472#c27, I think there is a confusion between front-end and middle-end problems: When the initialization expressions appear in PARAMETERS, they have to be computed by the front-end (?) which may lead to a very long compilation time, but I have never seen any memory problems (with Gbs of RAM), i.e., I did not have the patience to test large enough expressions. This is different to what happens for instance in pr32489 where the expression passed to the middle-end is so complicated that the middle-end is confused and exhausts the available memory. Adding a max-constructor-size check to MATMUL will again bring us here. Test by unconditionally returning NULL in MATMUL: ... I cannot reproduce that, am I correct to understand that you used some patched gfortran? Apparently, all the intrinsics should be audited for this kind of problem. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43996

[Bug rtl-optimization/44013] New: VTA produces wrong code
I first found this bug in GCC 4.5.0, but it is repeatable in mainline as of 159067. The attached preprocessed testcase, when compiled using -O2 -S will show the problem. We have a basic block [bb 3] with the following piece of code. [32] X(SI) = unspec_volatile (const_int 3) [33] var_location (some_var) = X [34] (subreg:SI (reg:DI Z) 0) = X ... [41] Y(SI) = unspec_volatile (const_int 3) [42] var_location (some_var) = Y [43] (subreg:SI (reg:DI Z) 4) = Y Combine combines 32-34 and 41-43 and converts this into [33] var_location (some_var) = unspec_volatile (const_int 3) [34] (subreg:SI (reg:DI Z) 0) = unspec_volatile (const_int 3) ... [42] var_location (some_var) = unspec_volatile (const_int 3) [43] (subreg:SI (reg:DI Z) 4) = unspec_volatile (const_int 3 I am not sure if this is a valid transformation in itself. var_location debug instructions now dont just use registers, but they have unspec_volatile which is assumed to clobber all register/memory. The scheduler dependency for this becomes 34-42-43 since the debug_insn in 42 actually clobbers everything. But, when scheduling instructions we ignore the debug_insn in 42 and hence the dependency is broken. 34 and 43 are both deemed ready, but 43 gets scheduled first which results in the two unspec_volatile instructions being reordered. I am not sure which of the steps above is incorrect. Any pointers on this would be greatly appreciated. Please let me know if you need any information.

Does the testcase fail with -fcompare-debug? From your description it is unclear what is going on. Perhaps you should attach snippets before and after scheduling and say what do you think is wrong and why. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44013

Well, it is a symptom of insane use of always_inline attribute (as seen in the testcase). The function is public yet marked always inline, so compiler really can't inline it everywhere no matter how hard it is trying. We are thinking about making this invalid in future relase of GCC. Always inline functions should be static and should not be used in scenarios we can not inline into. Honza alright.. so it's nothing too serious then.. From over here, I'm not going to be able to test this patch right away.. (but will), in the meantime if somebody already has 4.6.0 setup and everything they should run your patch and see.(right now in the process of working on an issue with SELinux, then hopefully in the next few days will throw in the system with 4.6.0 and try the patch out). -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43791

--- Comment #22 from dominiq at lps dot ens dot fr 2010-05-06 14:59 --- Have you been able to identify if there is an invalid optimization? I have started to follow the spaghetti plate without success so far. However, although I don't think the problem comes from any invalid optimization, I realized that '-funsafe-math-optimizations' (implied by -ffast-math) implies '-freciprocal-math'. Thus with a vanilla trunk at revision 159085 (gfcp), I tried: gfcp -O3 -ffast-math -fno-reciprocal-math ../doduc.f90 which worked. Then I did the following change: --- doduc.f90 2005-10-11 14:53:32.0 +0200 +++ doduc_nr.f902010-05-06 15:38:37.0 +0200 @@ -2378,13 +2378,13 @@ dvg = DNUg(I) drf = -dvf*rf*rf drg = -dvg*rg*rg -rp = r*(dvf/vf-dvg/vg) +rp = r*(dvf*rf-dvg/vg) alo = .925*(vf/vg)**.239 a = .67 IF ( al.GE.alo ) a = .47 vgj = VGJo(I) alop = alo*rp*.239/r -vbcrp = .25*vbcr*(dvf/vf-rp/(1.-r)) +vbcrp = .25*vbcr*(dvf*rf-rp/(1.-r)) alb = ALFb(I) alt = ALFt(I) tao = alop/(a*alo) (since rf = 1./vf) and it worked too (note that it did not with only one change in rp or vbcrp). Now the questions are: (1) why a change dealing with the propagation of minus signs interferes with reciprocal-math? (2) why moving VEC_safe_push from negate_value to eliminate_plus_minus_pair trigger the miscompilation? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43716

I do not understand why gcc distinguish between 'specifying register as output' and 'specifying as clobbering'. I always considered, that 'clobber list' specify list of items which may be changed *AFTER* the end of instruction(s). So I do not understand why adding eax in clobber list will break compilation. I found some posts where people create size_t dummy; and specify this variable as output. insted of just specifying this register in clobber-list. Why not to fix bug I have reported?

(2) why moving VEC_safe_push from negate_value to eliminate_plus_minus_pair trigger the miscompilation? Just to be clear, I do not think there is a miscompilation here. Just to be clear, (1) I have understood your point from the very beginning, (2) I disagree with it: if you get the right result with '-O3 -ffast-math' on *-linux-* and I get a segmentation fault on x86_64-apple-darwin10, it means that doduc.f90 is miscompiled for the latter. Note that I have gotten the correct result for doduc.f90 with '-O3 -ffast-math' several hundred times over the past years. The patch that [among other things] moved VEC_safe_push from negate_value to eliminate_plus_minus_pair did that to enable (a + (-b)) - (a - b) optimization in more cases. Unless I missed something, the only significant change in revision 158105 is the move of VEC_safe_push. The other ones are renaming broken_up_subtracts to plus_negates and moving static VEC(tree, heap) *plus_negates; where it is needed due to the move of VEC_safe_push. Unless there is something very weird, I cannot see how these two changes can affect the generated code. Note also that if the only effect of moving VEC_safe_push was to enable (a + (-b))- (a - b) optimization, it should not interfere with the optimization a/b - a*(1.0/b)). -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43716
