Patch1:         idfpml-20U1-sharedlib.patch
BuildRequires:  dos2unix

# Upstream does not provide support for ARM architecture.  Patching to treat
# armv7l as IA32 will get it to compile, but it fails the test suite.
# Need to file a bug in Red Hat Bugzilla, and block bug #485251.

%description
Software implementation of the IEEE 754R Decimal Floating-Point
Arithmetic specification.  Ensures compliance with the upcoming
revision of the IEEE Standard for Floating-Point Arithmetic.  The
library implements the functions defined for decimal floating-point
arithmetic operations in the 'DRAFT Standard for Floating-Point
Arithmetic P754', which is a revision of the IEEE Standard 754-1985
for Binary Floating-Point Arithmetic.

# On i686 but not x86_64, the test program will log some failures of the
# binary32_to_bid{32,64,128} functions to set the inexact status flag,
# but the numeric (or NaN) results are correct. The test code contains
# some mysterious code for a status "pollution_workaround", and doesn't
# abort when that occurs, so it's apparently not considered a major
# problem, and we'll ignore it.
