Evan Cheng 86468ccaf3 Backend is reponsible for aligning the stack. 
llvm-svn: 33388
 2007-01-20 02:08:16 +00:00
Evan Cheng 7ab6fa3a67 We not align the final stack slot but instead let the target do so in emitPrologue(). Each target can make adjustments to the stack frame and re-align the stack as it deem appropriate. Do not align it twice which can end up wasting stack space.

Evan Cheng fec133d2d1 Add test case extracted from lencod. Spiller was infinite looping in GetRegForReload(). 
llvm-svn: 33383
 2007-01-19 22:43:14 +00:00
Evan Cheng fc74e2de26 GetRegForReload() now keeps track which registers have been considered and rejected during its quest to find a suitable reload register. This avoids an infinite loop in case like this: 
t1 := op t2, t3
  t2 <- assigned r0 for use by the reload but ended up reuse r1
  t3 <- assigned r1 for use by the reload but ended up reuse r0
  t1 <- desires r1
        sees r1 is taken by t2, tries t2's reload register r0
        sees r0 is taken by t3, tries t3's reload register r1
        sees r1 is taken by t2, tries t2's reload register r0 ...

 2007-01-19 22:04:24 +00:00
Reid Spencer a96084901c Help the lli interpreter find the stderr/stdin/stdout symbols. These are 
needed for output to be generated. On Linux these are both global vars and
macro definitions so we have to special case Linux.

Reid Spencer e928a15c9e For this transform: store V, (cast P) -> store (cast V), P 
don't allow the transform if V and the pointer's element type are different
width integer types.

Reid Spencer a94d394ad2 For PR1043: 
This is the final patch for this PR. It implements some minor cleanup
in the use of IntegerType, to wit:
1. Type::getIntegerTypeMask -> IntegerType::getBitMask
2. Type::Int*Ty changed to IntegerType* from Type*
3. ConstantInt::getType() returns IntegerType* now, not Type*

This also fixes PR1120.

Patch by Sheng Zhou.

Evan Cheng df62250cee Modify emission of jump tables on darwin to emit an extra "l" label that 
delimits the boundaries of jump tables.  This lets the linker's dead code
stripping optimization do a better job.

Evan Cheng 9201100b29 Remove this xform: 
(shl (add x, c1), c2) -> (add (shl x, c2), c1<<c2)
Replace it with:
(add (shl (add x, c1), c2), ) -> (add (add (shl x, c2), c1<<c2), )

This fixes test/CodeGen/ARM/smul.ll

Evan Cheng 97057f37a5 - Target PIC style is no longer affected by relocation model. 
- In x86-64 mode, symbols with external linkage (not just symbols which are
  defined externally) requires GOT indirect reference.

Reid Spencer c050af9126 Clean up some code around the store V, (cast P) -> store (cast V), P 
transform. Change some variable names so it is clear what is source and
what is dest of the cast. Also, add an assert to ensure that the integer
to integer case is asserting if the bitwidths are different. This prevents
illegal casts from being formed and catches bitwidth bugs sooner.
