I'm not sure what your suggestion is exactly; the issue isn't the
size, it is
that the code in HandleArgument for general RECORD_TYPEs is looking
at getDeclaredType, not the type in the field. (So what this patch
does is
use the INTEGER_REGS case instead.) The wide use of getDeclaredType
and the comments describing it make me think it would be unsafe in
general
to change that. It would certainly be more elegant if it works, though.

Hi Dale,
> Treat struct { long long: 29; }; as int sized and
> aligned, rather than long long. ABI issue.
if you look at the DECL_SIZE of the bitfield, rather than
the type size, I think it gives you 29. If so, DECL_SIZE
should simplify things for you. In fact as far as I can
see you should never use the type size for a record field.
For example the struct conversion stuff uses DECL_SIZE everywhere
(except at one point in the field indexing - I have a patch to fix
that which I'll apply at some point). Not using the type size
makes all these "it's a big type shoved in a small place" problems
magically go away.
Ciao,
Duncan.

I've added a comment for that. I've also lifted the restriction that the dividend should be at least 32 bits wide. Currently, the dividend is computed with the minimum necessary bitwidth and extended, if needed, just before the division. The patch is here: http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20080211/058097.html I think it's a good idea to keep the PR open. It will prevent us from forgetting to turn off the hack in future... Wojtek ___ llvm-commits mailing list llvm-commits@cs.uiuc.edu http://lists.cs.uiuc.edu/mailman/listinfo/llvm-commits

to the RHS. This simple change allows to compute loop iteration count
for loops with condition similar to the one in the testcase (which seems

Re: [llvm-commits] [llvm-gcc-4.2] r46958 - in /llvm-gcc-4.2/trunk/gcc: config/i386/llvm-i386-target.h llvm-types.cpp
This fixes an ABI issue with unions on i386 (Darwin for sure, and I
hope Linux as well).
I believe the FIXMEs I added indicate a latent bug, but I'm not sure
what the intent was, so could whoever wrote this code originally take
a look?
(As an aside, assuming that there is a struct type that gets passed
the same way as any union type strikes me as dangerous. I don't think
there's any reason such a struct needs to exist.)

[llvm-commits] [llvm] r46955 - in /llvm/trunk: include/llvm/Analysis/ScalarEvolution.h include/llvm/Analysis/ScalarEvolutionExpander.h include/llvm/Analysis/ScalarEvolutionExpressions.h lib/Analysis/S
Author: wmat
Date: Mon Feb 11 05:03:14 2008
New Revision: 46955
URL: http://llvm.org/viewvc/llvm-project?rev=46955&view=rev
Log:
Fix PR1798 - an error in the evaluation of SCEVAddRecExpr at an
arbitrary iteration.
The patch:
1) changes SCEVSDivExpr into SCEVUDivExpr,
2) replaces PartialFact() function with BinomialCoefficient(); the
computations (essentially, the division) in BinomialCoefficient() are
performed with the apprioprate bitwidth necessary to avoid overflow;
unsigned division is used instead of the signed one.
Computations in BinomialCoefficient() require support from the code
generator for APInts. Currently, we use a hack rounding up the
neccessary bitwidth to the nearest power of 2. The hack is easy to turn
off in future.
One remaining issue: we assume the divisor of the binomial coefficient
formula can be computed accurately using 16 bits. It means we can handle
AddRecs of length up to 9. In future, we should use APInts to evaluate
the divisor.
Thanks to Nicholas for cooperation!

Hi Evan,
This breaks these:
test/CodeGen/X86/fold-mul-lohi.ll
test/CodeGen/X86/stride-nine-with-base-reg.ll
test/CodeGen/X86/stride-reuse.ll
on Linux. These tests should probably explicitly set the relocation
model to
static so that they always test what they're intended to test.
