* Speedup bitcode writer. Do not walk all values for all functions to emit ↵Devang Patel2010-06-021-4/+7

* Add special case bitcode support for DebugLoc. This avoidsChris Lattner2010-04-031-1/+8
| | | | | | | | | | | | | | having the bitcode writer materialize mdnodes for all the debug location tuples when writing out the bc file and stores the information in a more compact form. For example, the -O0 -g bc file for combine.c in 176.gcc shrinks from 739392 to 512096 bytes. This concludes my planned short-term debug info work. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100261 91177308-0d34-0410-b5e6-96231b3b80d8

* This is a major cleanup of the instruction metadata interfaces thatChris Lattner2009-12-281-9/+4
| | | | | | | | | | | | | | | | | | | | | | | I asked Devang to do back on Sep 27. Instead of going through the MetadataContext class with methods like getMD() and getMDs(), just ask the instruction directly for its metadata with getMetadata() and getAllMetadata(). This includes a variety of other fixes and improvements: previously all Value*'s were bloated because the HasMetadata bit was thrown into value, adding a 9th bit to a byte. Now this is properly sunk down to the Instruction class (the only place where it makes sense) and it will be folded away somewhere soon. This also fixes some confusion in getMDs and its clients about whether the returned list is indexed by the MDID or densely packed. This is now returned sorted and densely packed and the comments make this clear. This introduces a number of fixme's which I'll follow up on. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92235 91177308-0d34-0410-b5e6-96231b3b80d8

* Reimplement the parameter attributes support, phase #1. hilights:Chris Lattner2008-03-121-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | 1. There is now a "PAListPtr" class, which is a smart pointer around the underlying uniqued parameter attribute list object, and manages its refcount. It is now impossible to mess up the refcount. 2. PAListPtr is now the main interface to the underlying object, and the underlying object is now completely opaque. 3. Implementation details like SmallVector and FoldingSet are now no longer part of the interface. 4. You can create a PAListPtr with an arbitrary sequence of ParamAttrsWithIndex's, no need to make a SmallVector of a specific size (you can just use an array or scalar or vector if you wish). 5. All the client code that had to check for a null pointer before dereferencing the pointer is simplified to just access the PAListPtr directly. 6. The interfaces for adding attrs to a list and removing them is a bit simpler. Phase #2 will rename some stuff (e.g. PAListPtr) and do other less invasive changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48289 91177308-0d34-0410-b5e6-96231b3b80d8
