>Description:
cc1 version 3.1 20020114 (experimental) 486-suse-linux)
fails with an ICE when compiling the attached amd74xx.i,
which is a cut down version of drivers/ide/amd74xx.c from
Linux kernel 2.4.17, with -march=i686 -O2 :
amd74xx.i: In function `ata66_amd74xx':
amd74xx.i:42: insn does not satisfy its constraints:
(insn 157 120 79 (set (mem:QI (plus:SI (reg/f:SI 6 ebp)
(const_int -56 [0xffffffc8])) [10 ata66 S1 A8])
(reg:QI 4 sil)) 60 {*movqi_1} (nil)
(nil))
amd74xx.i:42: Internal compiler error in reload_cse_simplify_operands, at reload1.c:8345
When passing -march=i586 or lower, compilation succeeds, so
it seems to be i686 specific.
Output of 'gcc -v' is:
Reading specs from /usr/lib/gcc-lib/i486-suse-linux/3.1/specs
Configured with: ../configure --enable-threads=posix --enable-long-long --prefix=/usr --with-local-prefix=/usr/local --infodir=/usr/share/info --mandir=/usr/share/man --enable-languages=c,c++,f77,objc,java,ada --with-gxx-include-dir=/usr/include/g++ --with-slibdir=/lib --with-system-zlib --enable-shared i486-suse-linux
Thread model: posix
gcc version 3.1 20020114 (experimental)
>How-To-Repeat:
Compile the attached amd74xx.i with
gcc -c -march=i686 -O2 amd74xx.i
