To: gcc-bugs
* the exact version of GCC;
gcc version 3.4.0
* the system type;
The host/build/target system is i686-pc-linux-gnu,
* the options given when GCC was configured/built;
Configured with: /home/niva/src/gcc-3.4-binutils/configure
--with-gnu-as --with-gnu-ld --enable-generated-files-in-srcdir
--disable-checking --enable-languages=c
--srcdir=/home/niva/src/gcc-3.4-binutils
--prefix=/home/niva/local-osina --enable-cpp --enable-shared
* the complete command line that triggers the bug;
/home/niva/local-osina/bin/gcc -O3 -c ttt.c -mtune=i486
/home/niva/local-osina/bin/gcc -O3 -c ttt.c -mtune=i386
Note: we have initially detected the bug in gcc-3.4.0 targeted
for i386-*-elf
* the compiler output (error messages, warnings, etc.); and
ttt.c: In function `modlookup':
ttt.c:30: internal compiler error: in get_loop_body, at cfgloop.c:988
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
* the preprocessed file (*.i*) that triggers the bug, generated by
adding -save-temps to the complete compilation command, or, in the
case of a bug report for the GNAT front end, a complete set of
source files (see below).
int bytestart[5000 + 1];
unsigned char modtext[400 + 1];
unsigned char bytemem[2][45000L + 1];
long
modlookup (int l)
{
signed char c;
long j;
long k;
signed char w;
long p;
while (p != 0)
{
while ((k < bytestart[p + 2]) && (j <= l) && (modtext[j] == bytemem[w][k]))
{
k = k + 1;
j = j + 1;
}
if (k == bytestart[p + 2])
c = 1;
else if (j > l)
c = 3;
else if (modtext[j] < bytemem[w][k])
c = 0;
else c = 2;
}
}
