Chris Lattner a333819d63 refactor the top-level 'patches' section into a subsection of General Policies. 
Much of its content is now in other parts of the doc, and this brings it up
immediately after 'stay informed' and right before 'code reviews'.

Reid Spencer da81bf4d3e For PR1207: 
Revert patches that caused the problem. Evan, please investigate and reapply
when you've discovered the problem.

llvm-svn: 34399
 2007-02-19 03:20:00 +00:00
Reid Spencer 577f4bd78c Add some new constants. 
llvm-svn: 34398
 2007-02-19 03:18:22 +00:00
Reid Spencer 861c1cb67a 1. Fix some indentation and variable names in the get{Min,Max}Value methods. 
2. Implement toString for power-of-2 radix without using divide and always
   printing full words. This allows hex/binary to look at the bit
   respresentation of the APInt as well as avoid bugs in divide.

llvm-svn: 34396
 2007-02-18 22:29:05 +00:00
Chris Lattner 9f4707eb04 fix comment

llvm-svn: 34393
 2007-02-18 20:37:44 +00:00
Reid Spencer be4ddf6856 1. Use APINT_WORD_SIZE instead of sizeof(uint64_t) 
2. Teach slt about signedness.
3. Teach roundToDouble to properly sign extend.

llvm-svn: 34391
 2007-02-18 20:09:41 +00:00
Reid Spencer 68b6184884 1. "unsigned" -> "uint32_t" to gaurantee its bit width on all platforms. 
Size matters in this case.
2. Remove the unused whichByte private function, which was also broken.
3. Remove the non-const overload of the getWord function, getWord() is
   never used as an lvalue.
4. Rename some local variables for clarity (e.g. API -> Result).

llvm-svn: 34390
 2007-02-18 18:42:35 +00:00
Reid Spencer a856b6e985 1. Remove dead code (lshift function). 
2. Consolidate memory allocation into just two inline functions.
3. Convert "unsigned" to uint32_t to gaurantee its size.
4. Eliminate magic constants and replace with symbolic equivalent.
5. Improve code documentation slightly.
6. Simplify the logical operator code because bitwidths must be the same.
7. Fix indentation per coding standards.
8. Use exit-early style to reduce indentation in several functions.

llvm-svn: 34389
 2007-02-18 18:38:44 +00:00
Reid Spencer ee0a685ea1 Make add_1 exit early if carry is 0. 
Fix line breaks and 80 cols violation.
Simplify operator^= since bitwidths must be the same.

compile-time regression in LLC.

 2007-02-17 22:38:07 +00:00
Evan Cheng 2605082f0e - Changes how function livein's are handled, they now have a start index of 0. 
- When coalescing a copy MI, if its destination is "dead", propagate the
  property to the source MI's destination if there are no intervening uses.
- Detect dead function live-in's and remove them.

llvm-svn: 34383
 2007-02-17 11:15:40 +00:00

Evan Cheng 6accd480a2 Added findRegisterDefOperand(). 
llvm-svn: 34380
 2007-02-17 11:10:18 +00:00
Evan Cheng ef932b067d - Use MRegister::regsOverlap(). 
- Allow LiveVariables to track liveness of more registers.

llvm-svn: 34379
 2007-02-17 11:09:47 +00:00
Evan Cheng 0479014657 Added removeLiveIn and more livein iterators.

llvm-svn: 34376
 2007-02-17 11:06:00 +00:00
Evan Cheng 6457b9eff4 - Added regsOverlap() to test if two registers overlap. Or in case they are 
virtual registers, test if they the same.
- Added a virtual method to return target specific reserved registers, e.g. SP.

llvm-svn: 34375
 2007-02-17 11:04:35 +00:00
Chris Lattner 1f7d60262e Fix ixaddrs as well, allowing ppc64 to compile to: 
_test2:
        li r2, 0
        lis r3, 1
        std r2, 9024(r3)
        blr

instead of:

_test2:
        lis r2, 1
        li r3, 0
        ori r2, r2, 9024
        std r3, 0(r2)
        blr

This implements CodeGen/PowerPC/LargeAbsoluteAddr.ll:test2

llvm-svn: 34373
 2007-02-17 06:57:26 +00:00
Chris Lattner 3723c90455 new test 
llvm-svn: 34372
 2007-02-17 06:57:11 +00:00

_test:
        lis r2, 743
        li r3, 0
        stw r3, 32751(r2)
        blr

instead of:

_test:
        li r2, 0
        stw r2, 32751(48693248)
        blr

both ppc32 and ppc64.
