| | | | | | patterns with custom lowering to a target specific nodes. llvm-svn: 149216
* Add bitcode reader and writer support for ConstantDataAggregate, whichChris Lattner2012-01-304-3/+112
| | | | | | should be feature complete now. Lets see if it works. llvm-svn: 149215

| | | | | | a better doxyment group for convenience predicates. llvm-svn: 149211
* Move Clang's file-level locking facility over to LLVM's supportDouglas Gregor2012-01-293-0/+291
| | | | | | library, since it doesn't really have anything to do with Clang. llvm-svn: 149203
* Cleanups for EABI standard functionsAnton Korobeynikov2012-01-291-2/+7
| | | | llvm-svn: 149195
* Use base AAPCS for varargs functions even for AAPCS-VFP CCAnton Korobeynikov2012-01-291-1/+3
| | | | llvm-svn: 149194
* Fix some scavenger performance issues.Jakob Stoklund Olesen2012-01-292-24/+13
| | | | | | | | | | | | | - Don't call malloc+free in the very hot forward(). - Don't call isTiedToDefOperand(). - Don't create BitVector temporaries. - Merge DeadRegs into KillRegs. - Eliminate the early clobber checks, they were irrelevant to scavenging. - Remove unnecessary code from -Asserts builds. This speeds up ARM PEI by 3.4x and overall llc -O0 codegen time by 11%. llvm-svn: 149189
* Avoid creating BitVector temporaries.Jakob Stoklund Olesen2012-01-291-7/+7
| | | | llvm-svn: 149188
* Add a BitVector::reset(BitVector&) method.Jakob Stoklund Olesen2012-01-291-0/+10
| | | | | | | The alternative LHS &= ~RHS is way too slow because it creates a temporary that calls malloc/free. llvm-svn: 149187
* Fix typo.Nick Lewycky2012-01-281-2/+2
| | | | llvm-svn: 149185
* Add a note about a potential optimization for clz/ctz patterns for ARMBob Wilson2012-01-281-0/+16

* Ensure .AliasedSymbol() is called on all uses of getSymbol(). Affects ARM ↵James Molloy2012-01-284-2/+14

* Handle recursive variable definitions directly. This gives us better errorRafael Espindola2012-01-283-12/+28

| | | | llvm-svn: 149172
* Reapply r149159 with a fix to add to a PHI node with a non-null parent.Bill Wendling2012-01-281-34/+64
| | | | llvm-svn: 149164
* Remove code that adds live ranges for dead defs. It seems to be breaking things.Lang Hames2012-01-281-24/+0
| | | | llvm-svn: 149163
* Revert r149159 until I can fix tests.Bill Wendling2012-01-281-61/+32
| | | | llvm-svn: 149162
* Don't always create a separate block for the call to _Unwind_Resume.Bill Wendling2012-01-281-32/+61
| | | | | | | | | | | Sometimes there is only one 'resume' instruction per function. In those situations, we don't need a separate block for the call to _Unwind_Resume. In fact, it adds a lot of overhead to code-gen if we do that -- especially at -O0. If we have a single 'resume' instruction, just generate the call within that block. <rdar://problem/10694814> llvm-svn: 149159
* Fix Record Name ReferenceDavid Greene2012-01-281-1/+1
| | | | | | Get the record name though the init to avoid an assert. llvm-svn: 149153
* Silence warning about parens for && within ||Lang Hames2012-01-271-1/+1
| | | | llvm-svn: 149152
* Add r149110 back with a fix for when the vector and the int have the sameRafael Espindola2012-01-276-9/+78
| | | | | | width. llvm-svn: 149151
* Remove Deprecated FeaturesDavid Greene2012-01-271-250/+51
| | | | | | | | | | | | Move to a model where we build whatever branches are checked out in the source directories. This was a bit too smart (and complicated) in handling details best left to the user and the revision control system. In addition, get rid of support for llvm-gcc and building gcc as these are no longer necessary. llvm-svn: 149149
* Revert r149110 and add a testcase that was crashing since that revision.Rafael Espindola2012-01-274-53/+15
| | | | | | | Unfortunately I also had to disable constant-pool-sharing.ll the code it tests has been updated to use the IL logic. llvm-svn: 149148
* Add a "moveInstr" method to LiveIntervals. This can be used to move instructionsLang Hames2012-01-274-1/+234
| | | | | | | | | around within a basic block while maintaining live-intervals. Updated ScheduleTopDownLive in MachineScheduler.cpp to use the moveInstr API when reordering MIs. llvm-svn: 149147
* Backing out ill-considered 'refactor'.Lang Hames2012-01-271-39/+53
| | | | llvm-svn: 149146

* continue making the world safe for ConstantDataVector. At this point,Chris Lattner2012-01-2710-75/+108
| | | | | | | we should (theoretically optimize and codegen ConstantDataVector as well as ConstantVector. llvm-svn: 149116
* Unix line endingsMatt Beaumont-Gay2012-01-271-19/+19
| | | | llvm-svn: 149115
* Place the GEP instructions nearer to the instructions which use them.Bill Wendling2012-01-271-37/+36
| | | | | | | | | | | GEP instructions are there for the compiler and shouldn't really output much code (if any at all). When a GEP is stored in the entry block, Fast ISel (for one) will not know that it could fold it into further uses. For instance, inside of the EH handling code. This results in a lot of unnecessary spills and loads which bloat code and slows down pretty much everything. <rdar://problem/10694814> llvm-svn: 149114
* make sure the file's matching header is #include'd first.Chris Lattner2012-01-271-3/+1
| | | | llvm-svn: 149113
* Rewrite CanShareConstantPoolEntry to be implemented in terms of theChris Lattner2012-01-271-26/+26
| | | | | | | | mid-level constant folding APIs instead of doing its own analysis. This makes it more general (e.g. can now share a <2 x i64> with a <4 x i32>) and avoid duplicating a bunch of logic. llvm-svn: 149111
* enhance constant folding to be able to constant fold bitcast of Chris Lattner2012-01-273-2/+51
