* Add a natural stack alignment field to TargetData, and prevent InstCombine fromLang Hames2011-10-101-2/+10
| | | | | | | | | | | | | | promoting allocas to preferred alignments that exceed the natural alignment. This avoids some potentially expensive dynamic stack realignments. The natural stack alignment is set in target data strings via the "S<size>" option. Size is in bits and must be a multiple of 8. The natural stack alignment defaults to "unspecified" (represented by a zero value), and the "unspecified" value does not prevent any alignment promotions. Target maintainers that care about avoiding promotions should explicitly add the "S<size>" option to their target data strings. llvm-svn: 141599

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 134829
* Fix a regression caused by r102515 where explicit alignment on globals isCameron Zwarich2011-04-131-1/+1

| | | | | | | the max itself, so it is not easy to write a test case for this, but I added a test case that would fail if the code in AsmPrinter were removed. llvm-svn: 129432
* If a global variable has a specified alignment that is less than the preferredCameron Zwarich2011-04-131-2/+6
| | | | | | | alignment for its type, use the minimum of the specified alignment and the ABI alignment. This fixes <rdar://problem/9275290>. llvm-svn: 129428
* Merge System into Support.Michael J. Spencer2010-11-291-1/+1
| | | | llvm-svn: 120298
* Get rid of static constructors for pass registration. Instead, every pass ↵Owen Anderson2010-10-191-0/+2
| | | | | | | | | | | | | | | | | exposes an initializeMyPassFunction(), which must be called in the pass's constructor. This function uses static dependency declarations to recursively initialize the pass's dependencies. Clients that only create passes through the createFooPass() APIs will require no changes. Clients that want to use the CommandLine options for passes will need to manually call the appropriate initialization functions in PassInitialization.h before parsing commandline arguments. I have tested this with all standard configurations of clang and llvm-gcc on Darwin. It is possible that there are problems with the static dependencies that will only be visible with non-standard options. If you encounter any crash in pass registration/creation, please send the testcase to me directly. llvm-svn: 116820
