Bug ID: 61056
Summary: strchr (x, 0) is not converted to strlen (x)
Product: gcc
Version: 4.10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: olegendo at gcc dot gnu.org
Target: sh*-*-*
At least on SH and r210026 the following:
extern "C" const char* strchr (const char*,int);
const char* test (const char* x)
{
return strrchr (x, 0);
}
does not get converted to a strlen (x). It seems that tree-ssa-strlen is
trying to do something but always fails.
