d186d37694 Fix a bug where calling materializeModule could corrupt the module, reading 
multiple copies of the function into the Function*.

b43eb600c2 For PR1146: 
Use ParamAttrsList for writing parameter attributes. Since they are sparse
now, we also write them sparsely (saves a few bytes). Unfortunately, this
is a bytecode file format change.

4269ae1274 For PR789: 
Make the sys::Path::getFileStatus function more efficient by having it
return a pointer to the FileStatus structure rather than copy it. Adjust
uses of the function accordingly. Also, fix some memory issues in sys::Path.

fc2686da00 From Dan Gohman: 
While preparing http://llvm.org/PR1198 I noticed several asserts
protecting unprepared code from i128 types that weren't actually failing
when they should because they were written as assert("foo") instead of
something like assert(0 && "foo"). This patch fixes all the cases that a
quick grep found.

5a58a65c10 Switch ValueSymbolTable to use StringMap<Value*> instead of std::map<std::string, Value*> 
as its main datastructure.  There are many improvements yet to be made, but
this speeds up opt --std-compile-opts on 447.dealII by 7.3%.

d5427f5249 For PR1194: 
The bcreader counts on "primitive" types being inserted before they are
referenced in other types. With recent changes to the bcwriter, this fact
became exposed since IntegerType is no longer "primitive". We can no longer
count on all IntegerTypes being inserted early. This patch modifies
getOrCreateTypeSlot to insert any sub-type that can't possibly recurse
before we create the slot for the type. This has the benefit of reducing
the number of OpaqueType objects the reader needs to deal with.

02141c9762 Change the table datastructure to be a vector<smallvector>, instead of 
vector<vector> to avoid allocations.  This speeds up bcwriting of 447.dealII
from 0.8276 to 0.7637s (8.4%).

This concludes this round of proding the bcwriter into submission.  Final
speedup from 24.4s to 0.7637s (32x).

6301eb8919 Make BytecodeWriter::outputValueSymbolTable *significantly* less abusive 
of memory, through a combination of DenseMap and SmallVector.  This speeds
up bcwriter on 447.dealII from 1.31s to 0.82s (60% faster).

c2542fe089 make the datastructure used in BytecodeWriter::outputValueSymbolTable 
*slightly* less abusive of memory.  This speeds up the bcwriter from
1.83s to 1.32s (39% faster) on 447.dealII.

98373d22fb The ModuleLevel vector is often quite sparse. Switch it to a DenseMap. This 
speeds up bcwriting of 447.dealII by 40%, from 4.63s to 3.32s.

llvm-svn: 34135
 2007-02-10 06:38:19 +00:00

dc8f129004 Make the ModuleLevel datastructure more sane. When a function-local value 
is inserted into the table, it remembers that the value needs to be popped
off.  This makes purgeFunction much faster, speeding up bcwriting of 447.dealII
from 6.8->4.6s (47%).

d043d112d0 Only compute the module levels info once per module, instead of once 
per function.  This speeds up bcwriting on 447.dealII from 10.16s to 6.81s
(49%).

b005a435cd Clone and specialize CreateSlotIfNeeded into CreateFunctionValueSlot to handle 
function-local values.  This speeds up bcwriting a small 2.2% (10.384->10.156s
on 447.dealII), but paves the way for more important changes.
