[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:

    (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.

Can you attach the preprocessed source (the difference between solaris 8 and solaris 10 might be the 
headers are different).

I just tried to reproduce the ICE with the stage3 compiler (I had removed
the stage1 and stage2 directories already to free some space), but failed:
the file compiles without problems!?

I've no idea what's going on here.  I'll try again with current mainline.

I've used the following patch to successfully bootstrap on
sparc-sun-solaris2.10 with Sun Studio 8 cc:

Great!  But it's the wrong PR.  PR rtl-optimization/18224 is an ICE during
postreload.  The bootstrap pb with Sun CC is PR bootstrap/18058.

Drat; too many bugs at once :-)

I could successfully bootstrap mainline on sparc-sun-solaris2.10 with gcc
on 20041029, so the problem seems to be either gone or masked.

I haven't tried a full bootstrap since, but I suppose the PR can be closed.
