From 7f6aa2b162e5daaf7b9ccf05d749597d3d7cf460 Mon Sep 17 00:00:00 2001 From: Nick Lewycky Date: Wed, 8 Jul 2009 03:04:38 +0000 Subject: Remove the vicmp and vfcmp instructions. Because we never had a release with these instructions, no autoupgrade or backwards compatibility support is provided. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74991 91177308-0d34-0410-b5e6-96231b3b80d8 --- docs/LangRef.html | 111 ------------------------------------------------------ 1 file changed, 111 deletions(-) (limited to 'docs') diff --git a/docs/LangRef.html b/docs/LangRef.html index c57518b..416b105 100644 --- a/docs/LangRef.html +++ b/docs/LangRef.html @@ -155,8 +155,6 @@

    The 'vicmp' instruction returns an integer vector value based on -element-wise comparison of its two integer vector operands.

    -
    Arguments:
    -

    The 'vicmp' instruction takes three operands. The first operand is -the condition code indicating the kind of comparison to perform. It is not -a value, just a keyword. The possible condition code are:

    -
      -
    1. eq: equal
      2. -
    2. ne: not equal

    The remaining two arguments must be vector or -integer typed. They must also be identical types.

    -
    Semantics:
    -

    The 'vicmp' instruction compares op1 and op2 -according to the condition code given as cond. The comparison yields a -vector of integer result, of -identical type as the values being compared. The most significant bit in each -element is 1 if the element-wise comparison evaluates to true, and is 0 -otherwise. All other bits of the result are undefined. The condition codes -are evaluated identically to the 'icmp' -instruction.

    Example:
    -
    -  <result> = vicmp eq <2 x i32> < i32 4, i32 0>, < i32 5, i32 0>   ; yields: result=<2 x i32> < i32 0, i32 -1 >
-  <result> = vicmp ult <2 x i8 > < i8 1, i8 2>, < i8 2, i8 2 >        ; yields: result=<2 x i8> < i8 -1, i8 0 >

    The 'vfcmp' instruction returns an integer vector value based on -element-wise comparison of its two floating point vector operands. The output -elements have the same width as the input elements.

    -
    Arguments:
    -

    The 'vfcmp' instruction takes three operands. The first operand is -the condition code indicating the kind of comparison to perform. It is not -a value, just a keyword. The possible condition code are:

    -
      -
    1. false: no comparison, always returns false
      2. -
    2. oeq: ordered and equal
      3. -
    3. ogt: ordered and greater than

    6. ole: ordered and less than or equal

    The remaining two arguments must be vector of -floating point typed. They must also be identical -types.

    The 'vfcmp' instruction compares op1 and op2 -according to the condition code given as cond. The comparison yields a -vector of integer result, with -an identical number of elements as the values being compared, and each element -having identical with to the width of the floating point elements. The most -significant bit in each element is 1 if the element-wise comparison evaluates to -true, and is 0 otherwise. All other bits of the result are undefined. The -condition codes are evaluated identically to the -'fcmp' instruction.
