[llvm-commits] CVS: llvm/docs/LangRef.html

[Reid Spencer]

Changes in directory llvm/docs:

LangRef.html updated: 1.242 -> 1.243
---
Log message:

Revise definition of part_select. The wrapping behavior is not useful so
in the reverse case the only difference is that the bits are returned in 
reverse order.

   <li>A mask of the retained bits is created by shifting a -1 value.</li>

-  <li>The bits selected wrap around to include both the highest and lowest bits.
-  For example, part.select(i16 X, 4, 7) selects bits from X with a mask of 
-  0x00F0 (forwards case) while part.select(i16 X, 8, 3) selects bits from X 
-  with a mask of 0xFF0F.</li>
-  <li>The bits returned in the reverse case are reversed. So, if X has the value
-  0x6ACF and we apply part.select(i16 X, 8, 3) to it, we get back the value
-  0x0A6F.</li>
