[Bug target/28285] New: [4.2 Regression] duplicate case value in alpha_swapped_comparison operator

[gcc-bugzilla at gcc dot gnu dot org]

Bootstrapping current mainline on Tru64 UNIX fails in stage1 as of 20060705:

gcc -c   -g -fkeep-inline-functions -DIN_GCC   -W -Wall -Wwrite-strings
-Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition
-Wmissing-format-attribute -fno-common   -DHAVE_CONFIG_H -I. -I.
-I/vol/gcc/src/gcc/gcc -I/vol/gcc/src/gcc/gcc/.
-I/vol/gcc/src/gcc/gcc/../include -I/vol/gcc/src/gcc/gcc/../libcpp/include
-I/vol/gnu/obj/gmp-4.1.3/mpfr -I/vol/gnu/obj/gmp-4.1.3
-I/vol/gcc/src/gcc/gcc/../libdecnumber -I../libdecnumber    insn-preds.c -o
insn-preds.o
/vol/gcc/src/gcc/gcc/config/alpha/predicates.md: In function
`alpha_swapped_comparison_operator':
/vol/gcc/src/gcc/gcc/config/alpha/predicates.md:571: error: duplicate case
value
/vol/gcc/src/gcc/gcc/config/alpha/predicates.md:570: error: previously used
here
make[3]: *** [insn-preds.o] Error 1

Inspecting the generated insn-preds.c (alpha_swapped_comparison_operator),
there are indeed two case GTU entries.

Environment:
System: OSF1 bartok V5.1 2650 alpha
Machine: alpha

host: alpha-dec-osf5.1b
build: alpha-dec-osf5.1b
target: alpha-dec-osf5.1b
configured with: /vol/gcc/src/gcc/configure --prefix=/vol/gcc
--with-local-prefix=/vol/gcc --disable-nls --host alpha-dec-osf5.1b --build
alpha-dec-osf5.1b --target alpha-dec-osf5.1b
--with-gmp-dir=/vol/gnu/obj/gmp-4.1.3
--with-mpfr-dir=/vol/gnu/obj/gmp-4.1.3/mpfr
--enable-languages=c,c++,fortran,java,objc,ada --disable-libmudflap

How-To-Repeat:
Bootstrap mainline as above.
