 2002-12-15 16:20:23 +00:00
Chris Lattner 903a25d225 User defined operators are not supposed to live beyond the lifetime of the 
pass.  Detect and flag them.

Chris Lattner 98cf1f5d64 - Eliminated the deferred symbol table stuff in Module & Function, it really 
wasn't an optimization and it was causing lots of bugs.

llvm-svn: 4779
 2002-11-20 18:36:02 +00:00
Chris Lattner b251c3d727 Eliminate the concept of a deferred symbol table. The optimization really isn't, 
and it causes obscure bugs to show up in passes.

llvm-svn: 4777
 2002-11-20 18:07:48 +00:00
Chris Lattner b2e46c0714 Add a new Module::getNamedFunction method 
llvm-svn: 4758
 2002-11-19 18:41:44 +00:00
Chris Lattner 1f985e0d3c Add a method "getMainFunction()" that efficiently locates 'main' in a module 
llvm-svn: 4629
 2002-11-08 20:34:02 +00:00
Chris Lattner 4d2997f25d Fix nasty bug in ::isNeg() 
llvm-svn: 4470
 2002-10-31 17:09:06 +00:00
Chris Lattner f6cfaedcff Can simplify code now with the isCommutative() method. 
llvm-svn: 4461
 2002-10-31 04:24:23 +00:00
Chris Lattner cab6c33811 New isAssociative/isCommutative inspection methods, graciously contributed by 
Casey Carter.

llvm-svn: 4459
 2002-10-31 04:14:01 +00:00
Misha Brukman 632df28deb Fix spelling of `propagate'. 
llvm-svn: 4423
 2002-10-29 23:06:16 +00:00
Chris Lattner 820d971233 - Rename AnalysisUsage::preservesAll to getPreservesAll & preservesCFG to 
setPreservesCFG to be less confusing.

llvm-svn: 4255
 2002-10-21 20:00:28 +00:00
Chris Lattner 33100eddd2 - Eliminate SymbolTable::ParentSymTab, ST::localLookup, and 
Function::ParentSymTab.  These aren't needed at all.

llvm-svn: 4186
 2002-10-15 21:26:29 +00:00
Chris Lattner 163b890dfb - Dramatically simplify the Constant::mutateReferences implementation, 
allowing it to be called on all constant types (structures/arrays)

llvm-svn: 4160
 2002-10-14 03:30:23 +00:00
Chris Lattner 251a7e6231 Minor cleanups, no changes to functionality 
llvm-svn: 4157
 2002-10-14 00:48:57 +00:00
Chris Lattner 149376dee5 - Change Function's so that their argument list is populated when they are 
constructed.  Before, external functions would have an empty argument list,
    now a Function ALWAYS has a populated argument list.

llvm-svn: 4149
 2002-10-13 20:57:00 +00:00
Chris Lattner 69ce8674b5 - Rename Instruction::First*Op to *OpsBegin, and Num*Ops to *OpsEnd to 
reflect the fact that it's a range being defined.

llvm-svn: 4147
 2002-10-13 19:39:16 +00:00
Chris Lattner 2c6abeac43 - Make Value::replaceAllUsesWith work with constants correctly. This fixes 
bug FuncResolve/2002-08-19-ResolveGlobalVars.ll and gzip looks better.

llvm-svn: 4103
 2002-10-09 23:12:59 +00:00
Chris Lattner b1dd9bbc68 - Add new Constant::replaceUsesOfWithOnConstant which has an end result 
similar to User::replaceUsesOfWith but actually does the right thing for
    constants.

llvm-svn: 4102
 2002-10-09 23:12:25 +00:00
Chris Lattner 6023f638a1 - Remove Value::use_remove 
llvm-svn: 4090
 2002-10-09 00:25:05 +00:00
Chris Lattner 3ea0c188b7 Fix NASTY N^2 behavior that was causing the gzip benchmark to take forever to 
assemble.  Now we scan the use-list from the back when removing users instead
of from the front.

llvm-svn: 4086
 2002-10-08 23:46:55 +00:00
Chris Lattner 0d779712e7 Fix bug: Assembler/2002-10-08-LargeArrayPerformance.ll by using 
std::vector::reserve when possible

llvm-svn: 4085
 2002-10-08 23:33:52 +00:00
Chris Lattner caf5b504a3 Changes to support PHINode::removeIncoming changes 
llvm-svn: 4080
 2002-10-08 21:36:34 +00:00
Chris Lattner fae98a2d28 - Change PHINode::removeIncomingValue to delete the phi node if the last 
incoming value is removed!

llvm-svn: 4078
 2002-10-08 21:34:58 +00:00
Chris Lattner acb038e5c7 Expose new "recalculate" method from dominatorset 
llvm-svn: 4074
 2002-10-08 19:12:08 +00:00
Chris Lattner d131986b0f Global variables are now external if they don't have initializers, not 
"uninitialized"

llvm-svn: 4052
 2002-10-06 22:48:09 +00:00
Chris Lattner 78bc0fa29f Check that we don't have external varaibles with internal linkage 
llvm-svn: 4051
 2002-10-06 22:47:32 +00:00
Chris Lattner 4cd9df88a7 PHI nodes are not allowed to exist with zero incoming values, check that 
there aren't any like this.

llvm-svn: 4044
 2002-10-06 21:00:31 +00:00
Chris Lattner 2cedf1ce82 Fix a nasty problem with dominance calculation for unreachable blocks. 
If we had a CFG that look like Entry -> B, Unreachable -> B, then we would
not correctly determine that Entry dominated B, because Entry did not
apparently dominate "unreachable".  This patch fixes this by making the entry
node dominate all blocks, including unreachable ones.

llvm-svn: 4037
 2002-10-04 14:45:48 +00:00
Chris Lattner 58185f2df9 - Print the predecessors of a basic block instead of the number of uses of 
the block in the AsmWriter

llvm-svn: 4019
 2002-10-02 19:38:55 +00:00
Chris Lattner 52db271374 Make sure to use the TimerGroup that we created! 
llvm-svn: 3995
 2002-10-01 20:12:06 +00:00
Chris Lattner d5fc9023a8 Make sure not to count the PassManager wrapers 
llvm-svn: 3994
 2002-10-01 20:08:11 +00:00
Chris Lattner af751b8e72 Factor timer code out of PassManager implementation, into a generic interface 
exposed by Support/Timer.h.

llvm-svn: 3993
 2002-10-01 19:54:07 +00:00
Chris Lattner 6b6f540959 Fix a problem that was caused by stale analyses being in CurrentAnalyses 
llvm-svn: 3981
 2002-09-29 22:50:22 +00:00

- Make DominatorTree::Node not inherit from std::vector

llvm-svn: 3939
 2002-09-26 16:14:41 +00:00
Chris Lattner 4dfede8070 - Add new ctor to BasicBlock to allow insertion before any BB, not just at 
the end of the function.

llvm-svn: 3934
 2002-09-26 05:03:22 +00:00
Chris Lattner 480b37d479 * Fix ugly bug in previous checkin where I reused the name 'i' one too many times 
* Print out immutable passes in the -debug-pass=Structure report.

llvm-svn: 3923
 2002-09-25 22:26:52 +00:00
Chris Lattner ee0788d42d Add support for ImmutablePasses, which are not run, and cannot be 
invalidated.

llvm-svn: 3921
 2002-09-25 21:59:11 +00:00
Chris Lattner a450397247 Make sure that we abort if an error happens as early as neccesary. Before 
it was possible for the passmanager to continue running passes after the
verifier even if the module was not well formed.

llvm-svn: 3820
 2002-09-19 16:12:19 +00:00
Vikram S. Adve 0267d0c62e Remove specification of argument default from cpp file. 
llvm-svn: 3772
 2002-09-17 01:17:57 +00:00
Chris Lattner fc91ee91e8 Change the MallocInst & AllocaInst ctors to take the allocated type, not the 
pointer type returned.

llvm-svn: 3711
 2002-09-13 22:28:50 +00:00
Chris Lattner 426752738b include/llvm/DataTypes.h includes this #define so we don't need it anymore 
llvm-svn: 3708
 2002-09-13 22:24:57 +00:00
Chris Lattner 548002f3d5 Another portability fix provided via Casey Carter: 
ISSUE: getTimeRecord in lib/VMCore/Pass.cpp uses timeval and
gettimeofday() without including sys/time.h.

ACTION: Include sys/time.h.
llvm-svn: 3699
 2002-09-13 14:47:12 +00:00
Chris Lattner bae3c67050 Add a new BasicBlockPass::doInitialization/Finalization(Function &) pair of 
methods that may be useful for BasicBlockPasses.

llvm-svn: 3676
 2002-09-10 23:54:58 +00:00
Chris Lattner 66d3a46afc Tighten up assertion checking for binary operators, not allowing invalid 
instructions to _even be created_.
