2012-02-05reapply the patches reverted in r149470 that reenable ConstantDataArray,Chris Lattner
but with a critical fix to the SelectionDAG code that optimizes copies from strings into immediate stores: the previous code was stopping reading string data at the first nul. Address this by adding a new argument to llvm::getConstantStringInfo, preserving the behavior before the patch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149800 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-09Land the long talked about "type system rewrite" patch. ThisChris Lattner
patch brings numerous advantages to LLVM. One way to look at it is through diffstat: 109 files changed, 3005 insertions(+), 5906 deletions(-) Removing almost 3K lines of code is a good thing. Other advantages include: 1. Value::getType() is a simple load that can be CSE'd, not a mutating union-find operation. 2. Types a uniqued and never move once created, defining away PATypeHolder. 3. Structs can be "named" now, and their name is part of the identity that uniques them. This means that the compiler doesn't merge them structurally which makes the IR much less confusing. 4. Now that there is no way to get a cycle in a type graph without a named struct type, "upreferences" go away. 5. Type refinement is completely gone, which should make LTO much MUCH faster in some common cases with C++ code. 6. Types are now generally immutable, so we can use "Type *" instead "const Type *" everywhere. Downsides of this patch are that it removes some functions from the C API, so people using those will have to upgrade to (not yet added) new API. "LLVM 3.0" is the right time to do this. There are still some cleanups pending after this, this patch is large enough as-is. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134829 91177308-0d34-0410-b5e6-96231b3b80d8

2010-06-02Speedup bitcode writer. Do not walk all values for all functions to emit ↵Devang Patel
function local metadata. In one testcase, probably worst case scenario, the 70x speed up is seen. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@105360 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-03Add special case bitcode support for DebugLoc. This avoidsChris Lattner
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

2009-12-28This is a major cleanup of the instruction metadata interfaces thatChris Lattner
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

2009-11-01Revert 85678/85680. The decision is to stay with the current form of Chris Lattner
indirectbr, thus we don't need "blockaddr(@func, null)". Eliminate it for simplicity. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85699 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-31Make blockaddress(@func, null) be valid, and make 'deleting a basic Chris Lattner
block with a blockaddress still referring to it' replace the invalid blockaddress with a new blockaddress(@func, null) instead of a inttoptr(1). This changes the bitcode encoding format, and still needs codegen support (this should produce a non-zero value, referring to the entry block of the function would also be quite reasonable). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85678 91177308-0d34-0410-b5e6-96231b3b80d8
