It is more restricted than a function, and also applies to a global  
though.

How, why?  I don't see why an alias would have a calling convention.   
What would it be used for?

Why?  What client of getCalledFunction would that benefit?  If the  
aliased-to callee is already available there would be no reference to  
the alias in any call.

Sure, but when the LLVM linker runs, it can resolve them.

I don't see how this is any better than just adding an explicit list  
of GlobalAliases.

It could be.  isn't a useful vector so it probably  
doesn't

have an ABI Alignment. It should, however, default to whatever the
target's alignment is for float. Perhaps that case isn't covered in
TargetData or there's something else wrong with TargetData?

Did you walk through it in the debugger?


Yes. It appears that TargetData doesn't have logic to match the case
of vector types smaller than the smallest defined ABI vector type.
It's asserting in TargetData::getAlignmentInfo:

assert(BestMatchIdx != -1 && "Didn't find alignment info for this
datatype!");


Ahh.


I don't think it has enough information to be able to determine
whether or not it's being asked for the alignment of a smaller vector
type that could be mapped onto a non-vector type.

My feeling is that in this case getAlignmentInfo should return a
conservative fallback alignment the same way that's done for  
integers.


I think it should fall back to the ABI alignment of the scalar type.
If a target doesn't have an entry for a vector type, we can assume
that it will be scalarized.


Here's a patch to do it.

Urm... does seem fine now.  All I know is that my nightly tester ran one 
hour after the mirror was updated (according to the svn log), and yet it 
did not pick up 315.

I just updated and the changes that Chris committed for me last night

Re: [llvm-commits] CVS: llvm/test/C++Frontend/dg.exp

[Reid Spencer]

Christopher,

Sorry about that, my bad. This is now fixed.

I forgot that the ++ in C++ would be treated as regular expression
special characters and is, in fact, an invalid regular expression.  The
change was to just use "string first" to scan the string, not use a
regular expression. 


Reid.

For the record, GCC 3.4.6 also has this problem.

Perhaps that case isn't covered inTargetData or there's something else wrong with TargetData?Did you walk through it in the debugger? Yes. It appears that TargetData doesn't have logic to match the caseof vector types smaller than the smallest defined ABI vector type.It's asserting in TargetData::getAlignmentInfo:assert(BestMatchIdx != -1 && "Didn't find alignment info for thisdatatype!"); Ahh. I don't think it has enough information to be able to determinewhether or not it's being asked for the alignment of a smaller vectortype that could be mapped onto a non-vector type.My feeling is that in this case getAlignmentInfo should return aconservative fallback alignment the same way that's done for integers. I think it should fall back to the ABI alignment of the scalar type.If a target doesn't have an entry for a vector type, we can assumethat it will be scalarized. Here's a patch to do it.--Christopher Lamb

Yes. Definitely. But with separate commit (not with *.l and *.y).

It appears that Mac's have an older version of Bison that the one  
Reid was using. If this is a problem Reid should probably regenerate  
the files.

I think it doesn't matter, which bison version is used. The only
requirement - it should be "known to work" (e.g 2.x).

Ugh.  Is this really true in all cases?  Should we add something like:

#ifndef LLVM_TYPE_H
#error "dont' do this"
#endif

to the top of this file?

Yep, Anton's right.  We check in the .cvs files separately from  
the .l/.y files to make it easier to review the code.  The .cvs files  
are used by people without bison/flex (e.g. on win32).

It could be.  isn't a useful vector so it probably  
doesn't

have an ABI Alignment. It should, however, default to whatever the
target's alignment is for float. Perhaps that case isn't  
covered in

TargetData or there's something else wrong with TargetData?

Did you walk through it in the debugger?


Yes. It appears that TargetData doesn't have logic to match the  
case

of vector types smaller than the smallest defined ABI vector type.
It's asserting in TargetData::getAlignmentInfo:

assert(BestMatchIdx != -1 && "Didn't find alignment info for this
datatype!");


Ahh.


I don't think it has enough information to be able to determine
whether or not it's being asked for the alignment of a smaller  
vector

type that could be mapped onto a non-vector type.

My feeling is that in this case getAlignmentInfo should return a
conservative fallback alignment the same way that's done for  
integers.


I think it should fall back to the ABI alignment of the scalar type.
If a target doesn't have an entry for a vector type, we can assume
that it will be scalarized.


Here's a patch to do it.

I think that this can be written as:
((1 << (SubclassData>>1)) >> 1

which is branchless and simpler.

If that's the case then ATU.h should just be folded into Type.h and we
don't ever have to talk about this again :)

We'd have to fold value/type/atu together, not a good idea,

Tthe llvm.org DNS was down, rendering the site unreachable, at 7:30am  
Sunday. I don't know when Comcast fixed the link, but as an aside, I  
don't think that the secondary DNS for llvm.org is working. For me it

I just updated and the changes that Chris committed for me last  
night

are in the repository mirror. The rev # is 315.  Seems fine to me.



Urm... does seem fine now.  All I know is that my nightly tester
ran one
hour after the mirror was updated (according to the svn log), and
yet it
did not pick up 315.

That wasn't the problem.  svn reached the server; it just didn't find a 
new revision to pull.
