[BUG] libffi-3.0.8 doesn't compile on MX31

[Robert Schwebel]

Hi,

[Please Cc: me on reply, I'm not subscribed to the libffi list]

I'm trying to build libffi for ARM, especially for ARM1131EJ-S
(Freescale MX31):

 arm-1136jfs-linux-gnueabi-gcc -DHAVE_CONFIG_H -I. -I. -I./include -Iinclude -I./src -isystem /home/rsc/svn/oselas/bsp/pengutronix/OSELAS.BSP-Pengutronix-AllYes-trunk/platform-phyCORE-i.MX31/sysroot-target/include -isystem /home/rsc/svn/oselas/bsp/pengutronix/OSELAS.BSP-Pengutronix-AllYes-trunk/platform-phyCORE-i.MX31/sysroot-target/usr/include -I. -I./include -Iinclude -I./src -g -O2 -MT src/arm/sysv.lo -MD -MP -MF src/arm/.deps/sysv.Tpo -c src/arm/sysv.S  -fPIC -DPIC -o src/arm/.libs/sysv.o
src/arm/sysv.S: Assembler messages:
src/arm/sysv.S:203: Error: selected processor does not support `stfeqs f0,[r2]'
src/arm/sysv.S:208: Error: selected processor does not support `stfeqd f0,[r2]'

src/arm/sysv.S:286: Error: selected processor does not support `ldfd f0,[sp]'
src/arm/sysv.S:289: Error: selected processor does not support `ldfd f0,[sp]'

Does anyone have an idea what goes wrong here?

I've filled out a bug report along with some analysis:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40242

as it breaks (cross)compiling gcc with certain options enabled.

cheers, Marc

To be honest, you're probably the only person who is going to fix this, at
least in the short term.  It's pretty clear that you're going to have to
distinguish between these cases on the basis of configure options rather
than compiler #defines.
