Reid Spencer 363fd46199 Fix test/Assembler/2007-03-19-NegValue.ll by using the new "isSigned" 
parameter on ConstantInt::get to indicate the signedness of the intended
value.

 2007-03-19 20:40:22 +00:00
Reid Spencer 362fb29d80 Allow ConstantInt::get(Ty, uint64_t) to interpret the 64-bit values as a 
negative number. This is needed to fix test/Assembler/2007-03-19-NegValue.ll

llvm-svn: 35181
 2007-03-19 20:39:08 +00:00
Reid Spencer 6fae35acd3 Implement extension of sign bits for negative values in the uint64_t 
constructor. This helps to fix test/Assembler/2007-03-19-NegValue.ll

llvm-svn: 35180
 2007-03-19 20:37:47 +00:00
Reid Spencer 568b8b54dc Add an indication of signedness to the uint64_t constructor so sign bits 
can be extended. This helps fix test/Assembler/2007-03-19-NegValue.ll

llvm-svn: 35179
 2007-03-19 20:36:48 +00:00
Reid Spencer 732f0a838e Test case noticed by Sheng that fails because negative values that are 
greater than 64-bits don't have the sign bits extended on construction of
the APInt.

Reid Spencer fe65ae88fe For PR1248: 
Eliminate support for type planes in numbered values. This simplifies the
data structures involved in managing forward definitions, etc. Instead of
requiring maps from type to value, we can now just use a vector of values.
These changes also required rewrites of some support functions such as
InsertValue, getBBVal, and ResolveDefinitions. Some other cosmetic changes
were made as well.

llvm-svn: 35173
 2007-03-19 18:39:36 +00:00
Reid Spencer 49bd921f08 Add and Operator== method to ValID so equality can be done properly for 
named or numbered ValIDs.

llvm-svn: 35172
 2007-03-19 18:34:28 +00:00
Reid Spencer 508167861d For PR1258: 
Radically simplify the SlotMachine. There is no need to keep Value planes
around any more. This change causes slot numbering to number all un-named,
non-void values starting at 0 and incrementing monotonically through the
function, regardless of type (including BasicBlocks). Getting slot numbers
is now a single lookup operation instead of a double lookup.

llvm-svn: 35171
 2007-03-19 18:32:53 +00:00
Reid Spencer 7953b683fc For PR1258:

Evan Cheng ee2763f76f Special LDR instructions to load from non-pc-relative constantpools. These are 
rematerializable. Only used for constant generation for now.

llvm-svn: 35159
 2007-03-19 06:20:37 +00:00
Evan Cheng 0420161130 Add a TargetInstrDescriptor flag to mark an instruction as "re-materializable". 
It means the instruction can be easily re-materialized at any point. e.g.
constant generation, load from constantpool.
