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. --- Diffs of the changes: (+6 -11) LangRef.html | 17 ++++++----------- 1 files changed, 6 insertions(+), 11 deletions(-) Index: llvm/docs/LangRef.html diff -u llvm/docs/LangRef.html:1.242 llvm/docs/LangRef.html:1.243 --- llvm/docs/LangRef.html:1.242 Sun Apr 29 13:35:00 2007 +++ llvm/docs/LangRef.html Mon May 14 11:14:57 2007 @@ -4655,16 +4655,11 @@ <li>A mask of the retained bits is created by shifting a -1 value.</li> <li>The mask is ANDed with <tt>%val</tt> to produce the result. </ol> -<p>In reverse mode, a similar computation is made except that:</p> -<ol> - <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.
