[forwarded from http://bugs.debian.org/203835] A regression from 3.3 probably introduced between 20030722 and 20030728.

Fixed on the mainline by http://gcc.gnu.org/ml/gcc-patches/2003-06/msg02445.html. Aldy would you mind asking for this to go into the 3.3 branch after the release of 3.3.1.

I get the following similar error on i386 setup as cross compile to i386 I assume it is the same bug, but if not I can submit more info. /home/david/smart/tools/uClibc/bin/i386-uclibc-gcc -I./include -Wall -Wstrict-prototypes -Wshadow -Os -march=i386 -mpreferred-stack-boundary=2 -falign-functions=0 -falign-jumps=0 -falign-loops=0 -fomit-frame-pointer -D_GNU_SOURCE -DNDEBUG -c -o libbb/dump.o libbb/dump.c libbb/dump.c: In function `rewrite': libbb/dump.c:307: error: unrecognizable insn: (insn:HI 1049 918 1050 33 0x402a6e70 (set (reg:CC 17 flags) (compare:CC (const:SI (plus:SI (symbol_ref:SI ("lcc")) (const_int 1 [0x1]))) (reg/f:SI 110))) -1 (nil) (expr_list:REG_DEAD (reg/f:SI 110) (nil))) libbb/dump.c:307: internal compiler error: in extract_insn, at recog.c:2175 notebook:/home/david/smart/busybox-1.00-pre2 # gcc --ver Reading specs from /usr/lib/gcc-lib/i486-suse-linux/3.3/specs Configured with: ../configure --enable-threads=posix --prefix=/usr --with-local-prefix=/usr/local --infodir=/usr/share/info --mandir=/usr/share/man --libdir=/usr/lib --enable-languages=c,c++,f77,objc,java,ada --disable-checking --enable-libgcj --with-gxx-include-dir=/usr/include/g++ --with-slibdir=/lib --with-system-zlib --enable-shared --enable-__cxa_atexit i486-suse-linux Thread model: posix gcc version 3.3 20030226 (prerelease) (SuSE Linux)
according to Benjamin Herrenschmidt (http://bugs.debian.org/203835), http://gcc.gnu.org/ml/gcc-patches/2003-06/msg02445.html does fix the ICE on the mainline.
There is a patch for 3.3 at: http://gcc.gnu.org/ml/gcc-patches/2003-08/msg01356.html
This patch is OK for GCC 3.3.2.
committed.
This one is not fixed by the patch commited, that was a different bug. The patch for this bug is in <http://gcc.gnu.org/ml/gcc-patches/2003-06/msg02445.html>.

Aldy, please submit a patch for 3.3.
*** Bug 13436 has been marked as a duplicate of this bug. ***
Aldy could you back port the fixes, this is one of the most reported bugs now.
Hmmm.. this bug applies to 3.3.3 also, not only to 3.3.1 as described in the bug... I got this error with gcc 3.3.3.

(In reply to comment #16) > Aldy, please submit a patch for 3.3. Aldy, would you have a chance to submit a backport for 3.3.x?

This is a dup of 11092, which has not yet been fixed on the 3.3 branch. I verified the patch there works fine, though.
I don't know if it's the same bug, but I just tried snapshot from gcc-3.4: gcc -v Reading specs from /usr/local/lib/gcc/powerpc-unknown-linux-gnu/3.4.0/specs Configured with: ../gcc-3.4-20040114/configure --enable-altivec Thread model: posix gcc version 3.4.0 20040114 (experimental) and got ICE compiling ffmpeg like this: gcc -Wall -maltivec -mabi=altivec -g -O3 -DHAVE_AV_CONFIG_H -I.. -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -D_GNU_SOURCE -c -o ppc/idct_altivec.o ppc/idct_altivec.c ppc/mpegvideo_altivec.c: In function `dct_quantize_altivec': ppc/mpegvideo_altivec.c:165: internal compiler error: in add_location_or_const_value_attribute, at dwarf2out.c:9513 Please submit a full bug report, with preprocessed source if appropriate. See <URL:http://gcc.gnu.org/bugs.html> for instructions.
Note the ICE in dwarf-2 for 3.4 is PR11983.
