Brian Gaeke 87b4f0765c lib/CWriter/Writer.cpp: Copy AsmWriter's ConstantFP checking code here 
into a new function FPCSafeToPrint(), and use it in printConstant()

floating-point constants or as references to stack-allocated variables.

Chris Lattner 98fa07b1d5 Fix Bug: Linker/2003-04-26-NullPtrLinkProblem.ll 
This was a problem with constants having their types resolved to some new type,
but there was already a constant of the new type created.  Before, these types
were never merged together, now they are.

 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.

llvm-svn: 4801
 2002-11-21 16:54:22 +00:00
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: 4255
 2002-10-21 20:00:28 +00:00
Chris Lattner 33100eddd2 - Eliminate SymbolTable::ParentSymTab, ST::localLookup, and

llvm-svn: 4186
 2002-10-15 21:26:29 +00:00

 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

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

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 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

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.

Chris Lattner 675e7a9e3d - Fighting with linking problem due to removing the ::ID elements. Now the 
implementation .cpp files for analyses are not being included into gccas
    and friends because it is linking to the .a file and there is no explicit
    symbol reference to bring in the .o file.  The new IncludeFile hack is the
    result.
