Subject: [Qemu-devel] [PATCH v2 0/2] ARM: fix Neon vrecpe instruction.
Date: Wed, 16 Feb 2011 15:51:21 +0100 [thread overview]
Message-ID: <1297867883-18390-1-git-send-email-christophe.lyon@st.com> (raw)
From: Christophe Lyon <christophe.lyon@st.com>
These 2 patches fix the ARM Neon vrecpe instruction by matching the
algorithm descibed in the ARM ARM.
With these patches, qemu passes my ARM/Neon tests.
Patch #1 modifies softfloat by exporting float32_nan and
float32_infinity. For consistency, I have also moved all the
target-dependent definitions of floatXX_default_nan to softfloat.h (ie
the 16, 64, x80 and 128 bits versions in addition to the 32 bits
ones).
Patch #2 uses these newly exported values and uses the vrecpe
algorithm described in the ARM ARM.
Christophe Lyon (2):
softfloat: export float32_nan and float32_infinity.
target-arm: fix support for vrecpe.
