------- Comment #24 from yanov at il dot ibm dot com 2006-01-09 16:15 -------
You might be right; Compiling the code below without Mustafa's patch to
cfgrtl.c we get the following ICE on Power5: powerpc-linux if SMS is enabled:
gcc -O -c -fmodulo-sched smaller_comb.c
smaller_comb.c: In function foo:
smaller_comb.c:9: error: wrong amount of branch edges after conditional jump 9
smaller_comb.c:9: internal compiler error: verify_flow_info failed
this is the testcase:
int foo(short* vec1, short* vec2, short* vec3,int len )
{
int temp,i;
for (i=0; i<len; i++) {
temp = vec1[i] * 2;
temp += vec2[i] * 3 ;
vec3[i] = temp;
}
}
n_branch is 0 at the time the error occurs.
