[Bug bootstrap/18224] New: Bootstrap failure on Solaris 10/SPARC: ICE in reload_cse_simplify_operands, at postreload.c:391

[gcc-bugzilla at gcc dot gnu dot org]

Bootstrapping current mainline on Solaris 10/SPARC fails with an ICE in
stage2 (both with GCC 3.3.2 und 3.4.3 as bootstrap compiler):

stage1/xgcc -Bstage1/ -B/vol/gcc/share/sparc-sun-solaris2.10/bin/ -c   -g -O2 -DIN_GCC   -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -pedantic -Wno-long-long -Wno-variadic-macros -Wold-style-definition -Werror -fno-common   -DHAVE_CONFIG_H    -I. -Ijava -I/vol/gnu/src/gcc/gcc-dist/gcc -I/vol/gnu/src/gcc/gcc-dist/gcc/java -I/vol/gnu/src/gcc/gcc-dist/gcc/../include -I/vol/gnu/src/gcc/gcc-dist/gcc/../libcpp/include  /vol/gnu/src/gcc/gcc-dist/gcc/java/check-init.c -o java/check-init.o
/vol/gnu/src/gcc/gcc-dist/gcc/java/check-init.c: In function 'check_init':
/vol/gnu/src/gcc/gcc-dist/gcc/java/check-init.c:899: error: insn does not satisfy its constraints:
(insn 2359 4710 2366 195 /vol/gnu/src/gcc/gcc-dist/gcc/java/check-init.c:674 (set (reg:SI 10 %o2 [orig:1171 num_current_words ] [1171])
        (mem/i:SI (zero_extend:SI (reg:QI 1 %g1)) [4 num_current_words+0 S4 A32])) 51 {*movsi_insn} (nil)
    (nil))
/vol/gnu/src/gcc/gcc-dist/gcc/java/check-init.c:899: internal compiler error: in reload_cse_simplify_operands, at postreload.c:391

The problem vanishes with -O1, and I've been able to finish the bootstrap
by manually building java/check-init.o in stage2 and stage3 this way.

The error doesn't exist on Solaris 8/SPARC for some reason.

Environment:
System: SunOS padouk 5.10 s10_55 sun4u sparc SUNW,Sun-Fire-880
Architecture: sun4

	
host: sparc-sun-solaris2.10
build: sparc-sun-solaris2.10
target: sparc-sun-solaris2.10
configured with: /vol/gnu/src/gcc/gcc-dist/configure --prefix=/vol/gcc --with-local-prefix=/vol/gcc --disable-nls --disable-libmudflap

How-To-Repeat:
Bootstrap mainline as above.
