%description
This package provides an easy way for build jobs to force the CPU reported
to be ARMv6.

This helps to make sure that uname returns armv6 and that the instructions we
execute are only within the ARMv6 instruction space.

%prep
%setup -q -T -c -n %{name}

%build
gcc %{optflags} -shared -fPIC -o libfakearmv6l.so %{SOURCE2} -ldl
LD_PRELOAD=$PWD/libfakearmv6l.so /bin/uname -m

%install
install -D -m 755 libfakearmv6l.so %{buildroot}/%{_lib}/libfakearmv6l.so
mkdir -p %{buildroot}/etc/profile.d
install -m 644 %{SOURCE1} %{buildroot}/etc/profile.d/ldpreload-cputype-armv6.sh

%post
# Disable software emulation of cp15 barriers on arm64 kernels.
# This is slow and breaks some LLVM generated code:
# https://github.com/rust-lang/rust/issues/60605
if [ -e /proc/sys/abi/cp15_barrier ]; then
	echo 2 > /proc/sys/abi/cp15_barrier
