Problem with assembly sources on Solaris 10 SPARC with Oracle Studio 12.4

[Dennis Clarke]

Ran into this just yesterday with a build of libgmp 6.1.0 wherein the 
configure line was simply :

./configure ABI=64 --enable-cxx --prefix=/usr/local \
 > --libdir=/usr/local/lib


When I try to compile I very soon run into :

  /opt/solarisstudio12.4/bin/cc -D_STDC_C99= -c -DHAVE_CONFIG_H -I. -I.. 
-D__GMP_WITHIN_GMP -I.. -DOPERATION_gcd_1 -I/usr/local/include 
-I/usr/local/ssl/include -D_TS_ERRNO -D_POSIX_PTHREAD_SEMANTICS 
-D_LARGEFILE64_SOURCE -errfmt=error -erroff=%none -errshort=full

-xcache=8/16/4:4096/64/16 tmp-gcd_1.s -KPIC -DPIC -o .libs/gcd_1.o
libtool: compile:  ../mpn/m4-ccas --m4=/usr/local/bin/m4

-D__GMP_WITHIN_GMP -I.. -DOPERATION_gcd_1 -I/usr/local/include 
-I/usr/local/ssl/include -D_TS_ERRNO -D_POSIX_PTHREAD_SEMANTICS

-xstrconst -xildoff -m64 -xmemalign=8s -xnolibmil -Xc -xcode=pic32 
-xregs=no%appl -xlibmieee -mc -g -xs -ftrap=%none -Qy -xbuiltin=%none 
-xdebugformat=dwarf -xunroll=1 -xtarget=ultraT2 
-xcache=8/16/4:4096/64/16 gcd_1.asm -o gcd_1.o >/dev/null 2>&1

gmake[2]: *** [gcd_1.lo] Error 1
gmake[2]: Leaving directory `/usr/local/build/gmp-6.1.0/mpn'
gmake[1]: *** [all-recursive] Error 1
gmake[1]: Leaving directory `/usr/local/build/gmp-6.1.0'
gmake: *** [all] Error 2


When I search for the file gcd_1.asm I see multiple for various 
architectures and I make the guess that mpn/tmp-gcd_1.s is based on the 
source ./sparc64/gcd_1.asm for this system.

Also I see these warnings over and over :


"../gmp-impl.h", line 3699: warning:  attribute "mode" is unknown, ignored
"../gmp-impl.h", line 3700: warning:  attribute "mode" is unknown, ignored
"../gmp-impl.h", line 3701: warning:  attribute "mode" is unknown, ignored
"../gmp-impl.h", line 3702: warning:  attribute "mode" is unknown, ignored
"../gmp-impl.h", line 3703: warning:  attribute "mode" is unknown, ignored


So the simple work around is to build with configure option 
--disable-assembly and then everything works fine.

If more info is required ( I am guessing ) then let me know.
