Owen Anderson c1a3a471c4 Reduce contention on the Attributes lock by using atomic operations for reference counting rather than locking.

Dan Gohman 16f5415f5b Rename hasNoUnsignedOverflow and hasNoSignedOverflow to hasNoUnsignedWrap 
and hasNoSignedWrap, for consistency with the nuw and nsw properties.

Owen Anderson 3042539089 Privatize part of the leak detector mechanism, which turned out to be heavily contended 
when trying to run opt in parallel.  This lets parallel opt crunch 403.gcc in about a third
of the time.

llvm-svn: 79387
 2009-08-19 00:37:02 +00:00
Owen Anderson e8f2185a2f Privatize the ValueHandle global map. Because this is used so heavily throughout the code base, locking all accesses to 
it is not practical performance-wise.

Devang Patel c6faffde6c Add prefix only if it is needed.

Chris Lattner ee97b8b11c the MinPad argument to PadToColumn only really makes sense to be 1, 
just remove the argument and replace it with 1.

Erick Tryzelaar dd99135721 Expose creating constant ints and floats from strings in llvm-c. 
llvm-svn: 79213
 2009-08-16 23:36:46 +00:00
Erick Tryzelaar fc2280d874 Add helper functions to ConstantInt and ConstantFP to accept strings. 
llvm-svn: 79212
 2009-08-16 23:36:33 +00:00
Dan Gohman ff3af725ea Add a getOffsetOf, for building a target-independent expression for 
offsetof, similar to getSizeOf for sizeof.

llvm-svn: 79208
 2009-08-16 21:26:11 +00:00
Erick Tryzelaar 9813beadcd Add an llvm-c function that lets you insert an instruction with a name. 
llvm-svn: 79163
 2009-08-16 02:20:57 +00:00
Erick Tryzelaar 4cc690cce4 Expose most of the Constant creation functions to llvm-c. 
llvm-svn: 79160
 2009-08-16 02:20:12 +00:00
Erick Tryzelaar 3045b8b5d6 Expose most of the rest of IRBuilder's functions to llvm-c.

 2009-08-16 02:19:59 +00:00
Chris Lattner b1bf2009a4 switch DominanceFrontier::splitBlock to use a smallvector for 
the pred list instead of a vector, saving a boat load of malloc/free's.

llvm-svn: 79062
 2009-08-15 01:39:28 +00:00
Erick Tryzelaar 262332f24b Expose LLVMContext to llvm-c.

Owen Anderson a42ac6953b Actually privatize a IntegerTypes, and fix a few bugs exposed by this. 
llvm-svn: 78955
 2009-08-13 23:27:32 +00:00
Dan Gohman d57cbfc7d8 Make formatted_raw_ostream restore the buffer settings of the 
underlying stream when it is finished, so that clients don't
have to do this manually.

llvm-svn: 78952
 2009-08-13 23:16:59 +00:00
Dan Gohman 0809712def Take the fast path for any named value and any GlobalValue, which doesn't 
need TypePrinting despite being a subclass of Constant. This fixes
compile-time problems especially visible on 403.gcc when -asm-verbose is
enabled.

llvm-svn: 78951
 2009-08-13 23:07:11 +00:00
Owen Anderson 55f1c09e31 Push LLVMContexts through the IntegerType APIs. 
llvm-svn: 78948
 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.

llvm-svn: 78906
 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
don't need their number in a comment either.

Also, tidy up newline printing.

llvm-svn: 78865
 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.

llvm-svn: 78837
 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:

bb1:            ; preds = %bb
  %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]
  %6 = sext i32 %i.01 to i64            ; <i64> [#uses=1]
  %7 = getelementptr double* %p, i64 %6         ; <double*> [#uses=1]

After:

bb1:                                        ; preds = %bb
  %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]
  %6 = sext i32 %i.01 to i64                ; <i64> [#uses=1]
  %7 = getelementptr double* %p, i64 %6     ; <double*> [#uses=1]

Several tests required whitespace adjustments.

Dan Gohman 5476cfdb15 Remove a bunch more now-unnecessary Context arguments. 
llvm-svn: 78809
 2009-08-12 16:23:25 +00:00
Owen Anderson 117c9e8497 Add contexts to some of the MVT APIs. No functionality change yet, just the infrastructure work needed to get the contexts to where they need to be first. 
llvm-svn: 78759
 2009-08-12 00:36:31 +00:00
Dan Gohman 76733748e1 Simplify this code, and use an in-bounds GEP. 
llvm-svn: 78755
 2009-08-12 00:32:55 +00:00
Owen Anderson 9f94459d24 Split EVT into MVT and EVT, the former representing _just_ a primitive type, while 
the latter is capable of representing either a primitive or an extended type.

something else.

llvm-svn: 78702
 2009-08-11 19:56:00 +00:00
Daniel Dunbar 919fe2bd2f Simplify ConstantExpr::getInBoundsGetElementPtr and fix a possible crash, if 
constant folding eliminated the GEP instruction.
 - clang was hitting this on its test suite (for x86_64, at least).
