[Bug fortran/44471] Wrong call with variadic declaration
--- Comment #3 from burnus at gcc dot gnu dot org 2010-06-12 07:12 --- (In reply to comment #2) It is possible to get the front-end to construct a real argument types list from the arguments list of the external call, as is done in the patch attached. I think doing so is the proper way - the question is whether one should already do it earlier such that in resolve.c one can give a diagnostic for external foo call foo(3.0) call foo(4) ! error, inconsistent interface end Cf. PR 40976.) In any case, (re)constructing the interface from the call is sensible. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44471

[Bug middle-end/42505] [4.4/4.5/4.6 Regression] loop canonicalization causes a lot of unnecessary temporary variables
--- Comment #9 from sandra at codesourcery dot com 2010-06-12 07:42 --- I now have a specific theory of what is going on here. There are two problems: (1) estimate_reg_pressure_cost is not accounting for the function call in the loop body. In this case it ought to use call_used_regs instead of fixed_regs to determine how many registers are available for loop invariants. Here the target is Thumb-1 and there are only 4 non-call-clobbered registers available rather than 9, so we are much more constrained than ivopts thinks we are. This is pretty straightforward to fix. (2) For the test case filed with the issue, there are 4 registers needed for the two candidates and two invariants ivopts is selecting, so even with the fix for (1) ivopts thinks it has enough registers available. But, there are two uses of the form (src + offset) in the ivopts output, although they appear differently in the gimple code. RTL optimizations are combining these and allocating a temporary. Since the two uses span the function call in the loop body, the temporary needs to be assigned to a non-call-clobbered register. This is why there is a spill of the other loop invariant. Perhaps we could make the RA smarter about recomputing the src + offset value rather than resort to spilling something, but since I am dumb about the RA ;-) I'm planning to keep poking at the ivopts cost model instead. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42505

[Bug tree-optimization/44507] [4.5/4.6 Regression] vectorization ANDs array elements together incorrectly
--- Comment #3 from rguenth at gcc dot gnu dot org 2010-06-12 08:42 ---
Confirmed.
The vectorizer changes
# andVal_34 = PHI andVal_15(5), 0x0(3)
andVal_15 = curVal_13 andVal_34;
to
# vect_var_.26_52 = PHI vect_var_.26_53(5), { 1, 1, 1, 1 }(3)
vect_var_.26_53 = vect_var_.21_42 vect_var_.26_52;
4.4 works.

[Bug c++/44500] [C++0x] Bogus narrowing conversion error
--- Comment #12 from gpiez at web dot de 2010-06-12 08:46 --- I am closing this, as it isn't a gcc bug, as it behaves according to the standard. The bug is in the standard, as it mandates f1,1 // ok fCHAR_MAX, CHAR_MAX() // error gINT_MAX, INT_MAX() // no error, but undefined behaviuour f(char, char) // error g(int, int) // ok which is inconsistent and surprising. C++0x should really have got rid of the implicit integer promotion. Wasn't the intent of the implicit promotion to be able to write char a,b,c,d; a = b*c/d; and get a correct result even if b*c CHAR_MAX? I believe nobody does write code like this anymore, and even if, you could simply say undefined behaviour ;-) It doesn't work for ints anyway. Instead I have now an implicit integer promotion which forces me to use an explicit cast in compound initializers, where narrowing conversion isn't allowed, while in a simple assignment of course it is allowed (or else a hell would break loose... ). Why not make -Wconversion an error, at least this would be consistent ;-) -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44500

I'm in the long slow process of manually trimming down a testcase, but it is slow going. Essentially replace #include with a emacs buffer insert of that file and repeat. Then, trim down things while ensuring it still fails. gdb isn't happy for me, as this is a stage2 failure, not a stage1 failure, and debugging requires access to the .o files. The values in question are 0 and 0. If I remove a #define BLABLA_H, then the problem goes away, meaning the slightest sneeze, and this just shimmers. -- mrs at gcc dot gnu dot org changed: What|Removed |Added CC||mikestump at comcast dot net http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44509

(In reply to comment #3)
Fixing by reverting Steven patch is not enough to regain bootstrap on arm,
here
is the error during stage2:
This is a new unrelated error caused by r160458. You should IMO have opened a
new PR for it. Anyway, the patch below should fix it. Tested in a cross so
far, I'll do a native bootstrap of 4.6 head + this tomorrow. The declaration
bug for 'vec' is obvious. The fact that 'op1' is extracted but unused makes me
a bit nervous.
