Allow it to handle powf, add support for pow(x, 2.0) -> x*x. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49411 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/Transforms/SimplifyLibCalls/Pow.ll | 16 ++++++++++++---- 1 file changed, 12 insertions(+), 4 deletions(-) (limited to 'test') diff --git a/test/Transforms/SimplifyLibCalls/Pow.ll b/test/Transforms/SimplifyLibCalls/Pow.ll index fa638ef..c039d80 100644 --- a/test/Transforms/SimplifyLibCalls/Pow.ll +++ b/test/Transforms/SimplifyLibCalls/Pow.ll @@ -1,11 +1,10 @@ ; Testcase for calls to the standard C "pow" function ; -; Equivalent to: http://gcc.gnu.org/ml/gcc-patches/2003-02/msg01786.html -; RUN: llvm-as < %s | opt -simplify-libcalls | llvm-dis | \ -; RUN: not grep {call double .pow} -; END. +; RUN: llvm-as < %s | opt -simplify-libcalls | llvm-dis | not grep {call .pow} + declare double @pow(double, double) +declare float @powf(float, float) define double @test1(double %X) { %Y = call double @pow( double %X, double 0.000000e+00 ) ; [#uses=1] @@ -22,3 +21,12 @@ define double @test3(double %X) { ret double %Y } +define double @test4(double %X) { + %Y = call double @pow( double %X, double 2.0) + ret double %Y +} + +define float @test4f(float %X) { + %Y = call float @powf( float %X, float 2.0) + ret float %Y +} -- cgit v1.1
