Devang Patel c180029be4 Revert 80839 for now. It causes test failures.

2009-09-02 21:49:26 +00:00
Devang Patel 36309cd391 Use CallbackVH, instead of WeakVH, to hold MDNode elements.
Use FoldingSetNode to unique MDNodes in a context.
Use CallbackVH hooks to update context's MDNodeSet appropriately.

Torok Edwin 82131d6ad7 Opaque types didn't work if llvm_is_multithreaded().
AlwaysOpaqueTy is always NULL at this point, and it causes an assertion failure.
Fix it by using the just constructed tmp instead.

Torok Edwin d18e668fbc Free the constants that have no uses in ~LLVMContext.
This fixes leaks from LLVMContext in multithreaded apps.
Since constants are only deleted if they have no uses, it is safe to not delete
a Module on shutdown, as many single-threaded tools do.
Multithreaded apps should however delete the Module before destroying the
Context to ensure that there are no leaks (assuming they use a different context
for each thread).

Dale Johannesen 2aaf539564 Add an 'inline hint' attribute to represent source

Dan Gohman faf516f34d Use covariant return types for Instruction::clone, and eliminate
the forms of ExtractElementInst and InsertElementInst that are
equivalent to clone.

Dan Gohman 23d2c76f31 This should use isIndenticalToWhenDefined.
llvm-svn: 80039
2009-08-25 22:24:20 +00:00
Dan Gohman c8a27f2a5c Rename Instruction::isIdenticalTo to Instruction::isIdenticalToWhenDefined,
and introduce a new Instruction::isIdenticalTo which tests for full
identity, including the SubclassOptionalData flags. Also, fix the
Instruction::clone implementations to preserve the SubclassOptionalData
flags. Finally, teach several optimizations how to handle
SubclassOptionalData correctly, given these changes.

This fixes the counterintuitive behavior of isIdenticalTo not comparing
the full value, and clone not returning an identical clone, as well as
some subtle bugs that could be caused by these.

Thanks to Nick Lewycky for reporting this, and for an initial patch!

Dan Gohman 97d2cb8394 Allocate the basic types inside the LLVMContextImpl instance,
rather than separately with new. Move the members above the
TypeMap members to avoid destruction order issues. This fixes
a leak of these objects, and eliminates an extra level of
indirection in Type::getInt32Ty and friends.

Devang Patel 02aac922b4 Update DebugInfo interface to use metadata, instead of special named llvm.dbg.... global variables, to encode debugging information in llvm IR. This is mostly a mechanical change that tests metadata support very well.

Dan Gohman 0809712def Take the fast path for any named value and any GlobalValue, which doesn't

2009-08-13 21:58:54 +00:00
Dan Gohman 8061d9e23f Fix a 4x slowdown in llc -asm-verbose caused by the use of
WriteAsOperand in more places.

Now that more things are using WriteAsOperand, its behavior of
constructing a TypePrinting object and populating it with strings for all
the numbered types in the Module on each call is a significant bottleneck.
Fancier solutions could be pursued here, but for now, just bypass the
TypePrinting overhead in obvious cases.

2009-08-13 15:27:57 +00:00
Dan Gohman b4583b1b36 Change the indentation for LLVM Assembly files from 1 tab to 2 spaces.
This is vaguely consistent with LLVM's own source code, but more
importantly it lets more lines stay within 80 columns.

llvm-svn: 78879
2009-08-13 01:41:52 +00:00
Dan Gohman 69273e6474 Now that numbered types have their number printed, it's no longer
interesting to print the number in a comment. Numbered instructions

Also, tidy up newline printing.

2009-08-12 23:54:22 +00:00
Dan Gohman 466876b0a6 Extend the AsmWriter to print unnamed numbered types as "%0 = type ..."
and unnamed numbered global variables as "@0 = global ...". Extend the
AsmParser to recognize these forms.

llvm-svn: 78859
2009-08-12 23:32:33 +00:00
Dan Gohman 12dad639b5 Make AsmWriter more careful with formatted_raw_ostream so that
it doesn't leave the underlying stream in unbuffered mode when
the stream was originally buffered.

Also, change WriteAsOperand back to plain raw_ostream. This
lets it work for either formatted_raw_ostream or plain
raw_ostream, so that it doesn't have to force a buffer flush
on a plain raw_ostream.

2009-08-12 20:56:03 +00:00
Dan Gohman e274526d78 Make LLVM Assembly dramatically easier to read by aligning the comments,
using formatted_raw_ostream's PadToColumn.

Before:

  %2 = sext i32 %i.01 to i64            ; <i64> [#uses=1]
  %3 = getelementptr double* %p, i64 %2         ; <double*> [#uses=1]
  %4 = load double* %3, align 8         ; <double> [#uses=1]
  %5 = fmul double %4, 1.100000e+00             ; <double> [#uses=1]

Getelementptrs that are defined to wrap are virtually useless to

all intermediate addresses are within bounds. I'm going to take
a different approach.
